INTRODUCTION It simply isn’t an adventure worth telling if there aren’t any dragons. J.R.R. Tolkien

My Favorite Sicilian I was introduced to the Accelerated Dragon when I was ten years old, more than seventeen years ago. It was arguably my rst ‘serious’ defense against 1.e4: prior to then I would develop my pieces in a manner my father and I called ‘P-Play’ (the ‘P’ deriving from our family name) but which I later discovered is widely known as the Hippopotamus Defence. He and I were of similar strength at the time, and we studied the opening together from the then recently published, and now classic, Accelerated Dragons by IMs Donaldson and Silman. What drew me to the opening initially was the abundance of cheapos I could set up for my opponents in the early stages of the game, which even experts and masters seemed unprepared for. e following was always one of my favorites: 1.e4 c5 2.Nf3 g6 3.d4 cxd4 4.Nxd4 Bg7 5.Nc3 Nc6 6.Be3 Nf6 7.Bc4 Qa5 8.Qd2? 8.0-0 8...Nxe4! 9.Nxc6 9.Nxe4 Qxd2+ 10.Bxd2 Nxd4μ

As I have matured as a player, my perspective on this opening has correspondingly transformed, but my respect and appreciation for its strength has only been enhanced. is book is an attempt to convey my current understanding and approach with black. I have always felt that the Accelerated Dragon does not get its due respect among

the Sicilians. Even its prodigal brother, the un-accelerated Dragon, had its time in the spotlight when it was used by Kasparov to twice defeat (and twice draw) Anand in their 1995 PCA World Championship match. Why then, has the Accelerated Dragon — the theoretically no worse off, and much safer of the two (I like to think of it as the only Sicilian where Black needn’t worry about getting mated in 25 moves) — historically been only an occasional guest in top events, and, unlike every other respectable Sicilian, never occupied the central battle eld of a World Championship match?1 Part of the discrepancy is a vestige of the old (pre1970s) dogma that in the Sicilian, to avoid suffocation, Black must prevent White from obtaining a ‘clamp’ pawn center (pawns on e4 and c4). Indeed, the Maroczy Bind (5.c4) has always been the bane of the Accelerated Dragon’s existence. However, while this attitude towards the Sicilian may have been justi able half a century ago, Black has since demonstrated counterattacking prospects against the e4/c4 clamp in a variety of structures, as in the Hedgehog, Kalashnikov, Kan, Taimanov, and certainly no less in the Accelerated Dragon. I suspect that computers have deterred many potential devotees away from the Accelerated Dragon. Computer evaluations in the main lines tend to uctuate between +0.25 and +0.5, which plausibly leads to the rationale that playing the Accelerated Dragon instead of the Berlin or Marshall — where evaluations are closer to +0.15 — is like playing with a small handicap straight out of the opening. ings, however, are not

so simple. Computers evaluate each position by objective features, without regard for subjective factors which are very often more important in tournament chess. Machines systematically ignore the value of, for example, being able to follow one of a small number of thematic plans, irrespective of what the opponent does, saving on clock time as well as risk of mishandling the position. is sort of human element is unaccounted for by the engine, resulting in an in ated estimation of White’s chances. In this regard, there are similarities between the Accelerated Dragon and the King’s Indian Defense — another opening notoriously bastardized by the engine. King’s Indian devotees are used to seeing +0.5 computer evaluations, but they are not discouraged because they recognize that there is a narrow margin of error for White, and to err is human. e same can be said for the Accelerated Dragon. Fortunately, the tide of fashion is turning, and contemporary Accelerated Dragon experts like (super) Grandmasters Tiviakov, Mamedov, Iturrizaga, and Malakhov have demonstrated that this opening can be a reliable counter to 1.e4 even against top opposition. Recently, in fact, World Champion Magnus Carlsen upheld the Black side of a Maroczy to put a halt to Caruana’s 7-0 run in the 2014 Sinque eld Cup. I predict a bright future for this opening, for many reasons, but most of all because 1) e resulting positions are difficult for computers to properly assess- many ‘+=’ evaluations are more accurately ‘=’ but more importantly ‘easier to play for Black’, a factor which should not be underestimated especially

considering the increasingly short time controls, and 2) ere is plenty of unexplored terrain, which cannot be easily navigated by the positional dictums we are brought up with, because the Accelerated Dragon is a genuinely nonstandard opening. is means that there is a competitive advantage to those who work out its unusual nuances, unlike in, say, the Najdorf or Sveshnikov where it often feels like the strategic ideas are all well known, and only concrete novelties are yet to be discovered (if it is unclear what I mean by this, I hope it isn’t by the end of the book!).

e Accelerated Dragon State of Mind A friend of mine (a strong IM) recently commented to me that if he could be certain that his opponents wouldn’t play the Maroczy bind, he would always play the Accelerated Dragon instead of his usual (un-accelerated, but I sometimes teasingly prefer ‘un-playable’) Dragon, because White can’t play the critical Yugoslav Attack against the Accelerated Dragon (despite this being lesson #1 of the Accelerated Dragon, a surprising number of masters have not gotten the memo). “However”, he continued, “in the Maroczy, Black is just playing for a draw, you can never win!” A loyal defender of my beloved pet opening, I insisted he had it all wrong, and that I welcome the Maroczy in must-win games with Black. “at’s really weird dude, you’re probably the only one” was his retort, but I think when it comes to the Accelerated Dragon, there’s a requisite state of mind needed in order to properly handle it — some

players have had a conversion experience after catching a glimpse of its incredible power, while others haven’t. Plausibly as a result of this, from my experience there is a peculiar camaraderie among Accelerated Dragon practitioners. Whereas Najdorf ‘bros’ espouse a Darwinian angst that their novelty on move 25 in the Poisoned Pawn variation will be discovered, used, and rendered useless by their colleagues, I have found that Accelerated Dragon players enjoy discussing their ideas with each other. A personal anecdote of mine is fairly typical: in the nal round of the 2013 US Masters tournament I was in a must-win ‘money game’ with Black against Cuban GM Abreu, and I noticed GM Rauf Mamedov (a leading expert on the Black side of the Accelerated Dragon) was taking an interest in the Maroczy Bind on my board. I won the game in a tense struggle, and afterwards when I was collecting my prize, Rauf kindly congratulated me on the win and took an interest in the 15...e6 line I played (see chapter 5), which he said he hadn’t studied before. I told him I was not too happy with the more popular 15...Qb6, but he asserted that from his analysis Black has no problems there — “it’s equal” he said. His con dent proclamation was just the nudge I needed to look closer into some of the lines I thought were undesirable for Black, and on closer inspection I realized (unsurprisingly) he was right! While this elusive ‘state of mind’ is somewhat ineffable, and better grasped from experience than anything else (if I am successful then the contents of this book will convey precisely this), I think it is helpful to think of the Maroczy as a

close cousin of the Hedgehog. I understand the ‘philosophy’ of the Hedgehog in terms of how Mihai Suba describes it in his excellent Dynamic Chess Strategy. It is worth quoting him at length. “White’s position looks ideal. at’s the naked truth about it, but the ‘ideal’ has by de nition one drawback — it cannot be improved. ...In the early 1970s, the successes of Karpov and Andersson showed that [Hedgehog] positions are not only playable but offer as many winning chances as any other opening. is was in glaring con ict with classical strategy. White enjoys more space, better development [and] his position has no weaknesses. How is it possible that Black not only resists in these positions but sometimes wins? e only plausible answer lies in the hidden dynamics of the positions. After the opening, White’s position has all the qualities of a successful picture, but lacks concrete possibilities for improvement. Within our terminology, it is rigid (not elastic). Black’s position, in contrast, ‘looks’ bad but has greater scope for improvement.” (p. 26) is description applies equally well to the Maroczy. In fact, you might say that the Accelerated Dragon (speci cally the Black side of the Maroczy) ‘state of mind’ is, to borrow Suba’s phrase, an appreciation for the “hidden dynamic factors” in each position which compensate for the static de ciencies (again, the best way to ‘sense’ these is by studying the opening — the variations in this book are meant to illustrate these factors). Moreover, as a long time Hedgehog player myself, I must say that in my opinion, Black has much more

freedom in the Maroczy than in the Hedgehog; for instance, in the Hedgehog, it is usually unfavorable for Black to exchange queens, whereas in the Maroczy (and the Accelerated Dragon more broadly), White often takes pains to avoid exchanging queens so as to not lose the initiative, and that is a liability which contributes to the “rigidity” (another apt term of Suba’s) of White’s position. Terms like ‘elastic’ and ‘counterattacking potential’ will be interspersed throughout this book — they are much more informative than reductive evaluations like ‘=’.

An Inclusive Opening One of the remarkable things about the Accelerated Dragon is its appeal to players with vastly different styles. Compare Bent Larsen, the epitome of dynamic, offbeat, risky chess, with Sergei Tiviakov, who claimed in an interview recently that his style has been shaped most by Petrosian (who was a great Accelerated Dragon devotee himself ), Smyslov, and Karpov — both these players have championed the Accelerated Dragon as their main weapon against 1.e4 and yet their styles are in many ways polar opposites of each other! How can this be? I think the answer to this question is subtle and instructive. I think that when playing the Accelerated Dragon it ‘feels’ like you are playing White, not Black (albeit in a hypermodern manner). What I mean is, in chess, White tends to be the one to control the tempo of the game — usually it is White who chooses whether to enter into an opposite side castling situation, or to exchange pieces early on and maneuver around in a

simpli ed middlegame, or invoke the center as the locus of battle, ensuring king safety above all.2 Furthermore, Black usually needs to play accurately to not end up slightly worse, or at least give the initiative to White. e situation is, to the well prepared Accelerated Dragon player, precisely the reverse: in the Maroczy, for example, there are half a dozen different ways for Black to develop, and players of diverse styles can choose the one which suits them best (or vary their choice depending on practical considerations). Black controls the tempo and determines the character of the struggle, which is why it is so effective in must-win games. Furthermore, unlike in many 1...e5 openings, or in most other Sicilians like the Kan, Sveshnikov, or even the Najdorf, White’s choices are rather limited if he does not want to end up slightly worse out of the opening. In practice, White meets the Accelerated Dragon with either the Maroczy Bind or the 7.Bc4 variation; this is simply not so in the Najdorf where every single reasonable move is a viable candidate from the starting position of the Najdorf (6.h3, 6.Rg1, 6.g3, 6.f3, 6.Be3, 6.f4, 6.Be2, 6.Bc4, 6.Bg5, 6.a4, and that is not even to mention variations therein), and the margin for White error is far greater (for example 6.Be2 e5 7.Nf3!? is a serious challenge to the Najdorf but 6.Be2 Bg7 7.Nf3?! is just dubious against the Accelerated Dragon). e above may sound a little hyperbolic, and I would like to make it clear from the outset that I am not claiming that ‘Black is better’ in the Accelerated Dragon; to do so would be dishonest. My claim is a serious one: the character of the Accelerated

Dragon is that of a White opening. In fact, the Accelerated Dragon reversed is a White opening, called the English, and is fashioned by most of the top players in the world, including Carlsen, Kramnik, Aronian, Anand, Giri, and others: the exact piece arrangement occurs with colors reversed (and a tempo up) after 1.c4 e5 2.g3 Nf6 3.Bg2 d5 4.cxd5 Nxd5 5.Nc3, as well as 1.c4 c5 2.Nf3 Nf6 3.Nc3 d5 4.cxd5 Nxd5 5.g3 Nc6 6.Bg2 Nc7 7.0-0 e5 (reversed Maroczy). I have enjoyed playing this ‘reversed Accelerated Dragon’ with White as well. In addition to being inclusive in the above sense, that it can suit players of diverse styles, and also that it can be a coherent complement to a 1.c4 repertoire with White, there are many interesting ways that the opening ‘ ts’ with defenses against 1.d4/1.c4/1.Nf3, and can often directly transpose from them. King’s Indian: 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 i) 5.Nf3 0-0 6.Be2 c5 7.0-0 cxd4 8.Nxd4 Nc6 ii) 5.f3 0-0 6.Be3 c5 7.Nge2 cxd4 8.Nxd4 Nc6 Benoni/Benko Gambit: 1.d4 Nf6 2.c4 c5 3.Nf3 cxd4 4.Nxd4 Nc6 5.Nc3 g6 6.e4 1.d4 Nf6 2.Nf3 g6 3.c4 c5 4.Nc3 (4.d5 either 4...b5 or 4...e6) 4...cxd4 5.Nxd4 Nc6 6.e4 Symmetrical English:

1.c4 c5 2.Nf3 g6 3.d4 cxd4 4.Nxd4 Bg7 5.e4 Nc6 1.Nf3 c5 2.c4 g6 3.d4 cxd4 4.Nxd4 Bg7 5.e4 Nc6 Of course, there is no obligation on Accelerated Dragon players to deploy these defences in order to allow for transpositional possibilities — Tiviakov has been a lifelong Nimzo-Indian/Queen’s Indian devotee as a counterexample — but I have found it useful to play these systems in tandem myself. One more point on the topic of move orders: since the Accelerated Dragon (especially the Maroczy) can come about from so many different move orders, I have taken some liberties with the games in this book to convert the initial moves to the 1.e4 c5 2.Nf3 g6 ‘Hyper-Accelerated Dragon’ move order we will be focusing on. I have done this, following a not uncommon practice, purely for didactic purposes — I don’t want readers happy with their 1.d4 defenses to be confused by transpositions from openings they don’t play.

About is Book is book presents a repertoire for Black after 1.e4 c5 2.Nf3 g6 — the HyperAccelerated Dragon. I am relatively lax about distinguishing between ‘Accelerated Dragon’ (1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 g6) and ‘Hyper-Accelerated Dragon’, and I use the two interchangeably unless to emphasize move order nuances, for example, “the HyperAccelerated Dragon avoids the Rossolimo”. However, this is not merely ‘a’

Hyper-Accelerated Dragon repertoire, it is my repertoire, and I present the material as such, from a rst person perspective, making brazen use of my own games and offering personal anecdotes and opinions. is stylistic choice risks my coming across as presumptuous and at times even boastful, but my hope is rather that the conversational mode of presentation makes readers feel as though I am their tour guide through what might otherwise feel like an insurmountable labyrinth of variations. Further on the point of stylistic choices, I am regrettably not sufficiently skilled in writing without gender-speci c pronouns, so please regard all generic references to ‘he’ as ‘s/he’ (or alternative) and so on. I provide as much information as I think is necessary for readers to play this opening with Black; however, this is absolutely not meant to be an anthology on the opening. I make no claim to cover every conceivable variation White can play. Any attempt at such, couched under the heading of a ‘complete repertoire’ would not only be misleading, but in this day and age obsolete. is is not to say that opening books are altogether obsolete; on the contrary, as inundated with information as we all are nowadays, it can be enormously helpful to have an author divulge opening secrets from their years of experience which would not easily be gathered from a database search. What is obsolete is the attempt to thoroughly and comprehensively ‘prove equality’ with Black, and more importantly for our purposes it is antagonistic to the spirit of the Accelerated Dragon, which is that of an opening

refusing to be evaluated on static grounds alone. As Jonathan Rowson instructs in his Seven Deadly Chess Sins, “You need to assess not only the position as it stands but the position as it has changed and how it is likely to continue to change”. (p.75) So, I am not a big fan of evaluations like ‘=’ or ‘=+’ or ‘+=’ (though I capitulate to these at times) because ‘=’ makes me think of a draw and ‘+=’ makes me feel like I ought to be satis ed with a draw as Black, when in reality Black can very much be optimistic about his position despite such evaluations, and that is why I prefer evaluations like “counterplay” or “mutual chances”. If you encounter a variation not covered in this book, for example 1.e4 c5 2.Na3, my general prescription is this: nd a database (no excuses, they are free online), and search the position with an Accelerated Dragon player (I gave you a list above) as Black to see how they have chosen to play the position. Ideally you’ll nd a model game that you can recall whenever you face the system; after all, when it comes to rare systems like 2.Na3 it is foolish to memorize concrete variations since you’ll never remember them anyway, but the key ideas of a model game you can. Even in the main lines of the Accelerated Dragon, don’t try to memorize the moves given in this book as if they are the ultimate truth. ey aren’t. Your learning will be enhanced if you actively seek out novelties of your own, and try to understand how the various positional ideas for both sides t together. To make this book as valuable to the Petrosian-style (risk-averse) Accelerated

Dragon player as to the Larsen-type (riskcraving), I have recommended two systems against each of the 7.Bc4 and Maroczy Bind variations. I hope at least one of these suits you. For those among you who will embark on the risky course (‘My System’ against 7.Bc4 and the Breyer Variation of the Maroczy), may I caution you to do so with a realistic attitude towards the cost of risk-taking in chess. It is in the (mathematical) nature of risktaking that it increases the variability of outcomes — both good and bad. e mature risk taker is mindful of this, cognizant that their risk-taking is compatible with their aims and justi cations. is was the attitude of Bent Larsen. If you would like to play the Accelerated Dragon ambitiously, with a tolerance for risk, keep in mind the following description of Larsen, given by Reshevsky: “He is a rm believer in the value of surprise. Consequently, he often resorts to dubious variations in various openings. He also likes to complicate positions even though it may involve considerable risk. He has a great deal of con dence in his game and fears no one. His unique style has proven extremely effective against relatively weak opponents but has not been too successful against top-notchers.” Alas, this is the risk-taker’s predicament, but far from discouraging it, I am thankful for the risk-takers among you who resist the ‘genetic’ drift of our chess community towards timidity and results-oriented pragmatism. I sincerely hope you nd this to be an enjoyable and enriching experience.

1 We begin with the variation which epitomizes the Accelerated Dragon philosophy. In most defenses to 1.e4, White has the option of playing a ‘Classical’ variation by developing the light squared bishop to e2. is is particularly the case in Sicilians like the Najdorf, Scheviningen and Taimanov, but also in other defenses like the Pirc/Modern and

Alekhine. In all these systems, the Classical Variation offers White serious chances to obtain an opening advantage, and the immortal games of past champions like Geller and Karpov provide textbook illustrations of successful ‘Classical’ 1.e4 play. In contrast, the Be2 (Classical) variation against the ordinary, un-Accelerated Dragon is rather harmless for Black, the Yugoslav Attack being its critical test. As Accelerated Dragon players, we are in an even more favorable situation than ordinary Dragon players when it comes to the Classical variation, because we can choose to transpose to harmless variations of the Classical Dragon by opting for ...d7-d6 at opportune moments, and in some lines we can strike with ...d7-d5 directly, saving a full tempo compared with analogous lines in the Dragon. Despite the fact that this system offers White no advantage, it is still seen in about 15% of Accelerated Dragons (the other 85% are nearly evenly distributed between the Maroczy and Bc4 variations), the bulk of which occur at the club level. 1.e4 c5 2.Nf3 g6 3.d4 cxd4 4.Nxd4 Bg7 5.Nc3 Nc6

is is not part of the Be2 system so I just mention it in passing. Some people who like to anchetto their light bishop in other Sicilians play this ‘Chameleon’ line; such variations are apt against tamer Sicilians like the Najdorf, not the unforgiving Accelerated Dragon.

Black’s compensation is of a long-term nature. For the sacri ced piece he currently has two pawns, control over the center, and most of White’s pieces are awkwardly placed.

Black is not supposed to be able to play this; the general rule is that, except in extraordinary circumstances, Black must castle before playing this. Obedience to that rule is likely why this move has never

been played by a 2400+ player (at least according to the database). Computers are helpful for showing us the exceptions to our rule of thumb heuristics. Nevertheless, Black is not better off here than he is in the main line (7...0-0), it is just another path to easy equality. 8.Bb5 8.exd5 Nxd5 9.Nxc6 bxc6 10.Nxd5 Qxd5 11.0-0 0-0= We have transposed to the 7...0-0 8.0-0 d5 line. 8...0-0 9.Bxc6 9.Nxc6 bxc6 10.Bxc6 Rb8© 9...bxc6 10.Nxc6 Qc7 11.exd5 e6!

In their words, “We call this system the Anti-Yugoslav because 7...Qa5 more or less forces White to castle kingside and thus avoids the dangers of the Yugoslav Attack in the Dragon.” is concession from White is not without compromise from Black. In his repertoire book on the White side of 1.e4, Negi points out the defects in Black’s position: “...the queen on a5 is badly placed — it just gets in the way of Black’s typical plans like ...Na5, or ...b5/...a5. Now ...b5 can always be met by a2-a3 without any worries. Black also has the typical plan of ...Nxd4 and ...Bc6 available but if White avoids playing f2-f4, the positions after Nd5 (intending to meet ...Bxd5 with exd5) seem quite pleasant for him. Moreover, it is not easy for Black to

nd a new square for the queen. Going to c7 will only encourage Bg5, with ideas of Bxf6 and Nd5, so the most common plan is ...Qh5. Although this may offer a few tactical tricks, it’s hard to believe that the queen can be well placed there.” I do not disagree with Negi — Black’s queen usually does need to be relocated from a5, because the c6-Knight wants that square, and very often Black’s maneuvers in this system are (in his words) “hard to believe”. at being said, the fact that White players will be incredulous towards Black’s maneuvers is a positive feature of Black’s strategy (in this speci c variation and more broadly in the Accelerated Dragon), not a reason to avoid this line. In my experience playing this system over the board for more than sixteen years, White players have real difficulty managing their position, because Black’s Queen on a5 means that play neither resembles the Yugoslav Attack nor does it follow the usual paths in the Bc4/0-0 Dragon. White therefore must be extremely accurate in order to pose any problems whatsoever for Black, and more often than not White players are unprepared to do so. Black, in his favor, is usually con ned to deciding between a few typical themes, and that makes his life much easier. In the introduction to the book I mentioned that I was initially drawn to this system for its incredible “cheapo potential”, but to reassure the reader that this is a serious, safe, and reliable counter to 7.Bc4, I point out that Ivanchuk relied on this system at the highest stage when he employed it against Grischuk in the

London Candidates, 2013 (see 10.Nd5!? in the next subchapter). 8.0-0 Conventional wisdom dictates that this is basically forced, but in my opinion 8.f3 is not to be underestimated either. 8.Qd2? For White players who have never seen 7...Qa5, this blunder is not a rare occurrence. 8...Nxe4! 9.Nxc6 (9.Nxe4 Qxd2+ 10.Nxd2 Nxd4μ) 9...Qxc3!!μ

I’ve had the pleasure of playing this over the board many times. Black is up at least a pawn in all variations.; 8.Nb3? Another frequent sighting when facing unprepared opposition. 8...Qb4! 9.Bd3 (9.Nd2 Apparently, according to Donaldson and Silman, this was an idea of the late GM Pilnik, who felt that White had enough compensation for a pawn.

Black must not allow White to play Qd2 and 0-0-0, establishing a Yugoslav setup. e ‘Anti-Yugoslav variation’ wouldn’t be aptly named if it allowed this! 9.Ndb5! White takes advantage of Black’s queen being on b4, and therefore the c7 square being vulnerable. is move has

surprisingly been overlooked by other commentators. (9.Bb3? Nxe4 10.Nxc6 Bxc3+ 11.bxc3 Qxc3+ 12.Ke2 dxc6 13.Qd4 Qxd4 14.Bxd4 Nf6 15.Rhe1 Rg8!

By far the most popular move for White here is 9.Bb3, which will be the subject of the next few chapters. Here we consider alternatives for White. 9.Nb3 is is a clever line: if Black continues 9...Qa5-d8, White intends to accept the loss of a tempo with Bc4-e2, because Black has lost two tempi with ...Qd8-a5d8. us, a position from the Classical Dragon is reached a full tempo up for White. is was reason enough for Donaldson and Silman to attribute a “?” to 9...Qd8, but in my judgment the Classical Dragon is ‘so equal’ that even a tempo down, Black has no problems. 9.f3?!

I recommend calling White out on their cleverness. If White plays the 7.Bc4

XIIIIIIIIY

variation against the Accelerated Dragon (as opposed to 7.Be2) in the hope that they will be able to favorably transpose into a 7.Be2 line, then they probably don’t have much experience with Be2 systems, so we should welcome this transposition. Besides, it is no more correct to say that Black is down a tempo in this line than it is to say that Black is up a tempo in the Classical line as compared to this one! Retreating the queen to d8 is the simplest way for Black to handle the position; he intends to continue in the same fashion as I recommended in the Be2 chapter. It is worth mentioning that super GM Malakhov has adopted this move in more than one tournament game. 9...Qh5

I used to enjoy playing this when I was younger. It amazed me that Black’s queen could get away with such tightrope acrobatics.

10.Bg5² Perhaps it is a little harsh to evaluate this as +=, because the truth is, it is just an interesting game after, for example, 10...e6!?. In this opening, though, what matters is the level of counterplay, not objective assessment. With White threatening Bg5xf6 and Nc3d5, Black’s counterplay is put on hold in order to defend further, and so compared to 10...Qd8! which genuinely offers equal chances, I assess this as slightly preferable for White. (10.f4 d6 11.Be2 a6 12.Qe1 Bg4 13.Bxg4 Nxg4 14.Nd5 Qd8 (14...Qb8 15.c3 e6 16.Nb6 Nxe3 17.Qxe3 Qa7 18.Rad1 Rad8=) 15.Bb6 Qd7 16.Rd1 Nf6 17.Nxf6+ Bxf6 18.e5² 1–0 (62) Wei Yi (2641)-Bu Xiangzhi (2710) Zhongshan CHN 2014) 10.Be2 10.Bg5 d6 11.Re1

Since this variation is discussed, tempo up, in the chapter on the Be2 (Classical) Accelerated Dragon, here we will only consider attempts by White to take advantage of the extra tempo with aggressive play.

Black has counterattacking ideas such as ...Kh8/Rg8, ...Ne8-g7, and ...Bd7-c6. White’s king is weaker than Black’s, because whereas Black’s king can hide on h8, White’s corresponding h1 square is vulnerable to ...Bd7-c6 (a consequence of White’s overextension).

Black has solved his opening problems. It is crucial to understand that if Black succeeds in exchanging on d4, and exchanging queens with ...Qa5-c5, then Black is to be preferred (though not enough to seriously plan for more than a draw), for typical Sicilian reasons: more central pawns, potential queenside minority attack, etc.; 10.Qd2?

As I have mentioned, Black’s main plan in this system begins with exchanging on d4 and playing ...Bd7-c6. e prophylactic 11.Nf3!? prevents this idea, but it is better for White to wait a move to ask Black to commit a piece before playing Nd4-f3, especially since on this move 11...Nxd4 is dubious. 11...Rfc8 It was hard to decide which move to recommend in this line, but I am happy with this choice for two reasons: 1) Black’s next few moves (except after 12.f4) can be pretty much played on autopilot (...Bd7-e8, ...Nf6-d7-c5) — one shouldn’t underestimate the value of such conveniences.

close to equal but without many winning chances; 11...Rac8 (Even though I am not recommending this, it will be instructive for the reader to play through these variations to get a feel for why 11...Rfc8 is a better choice, especially to play for a win.) 12.Nf3 a) 12.Qe2!? Prophylaxis against ...Nc6e5, because now White will be able to hit the e5 knight with f2-f4, and the c4square will be unavailable to it. 12...a6 13.Rad1 Qc7 14.Nd5 Nxd5 15.exd5 Ne5 16.Qd2 Rfe8 17.Bh6 Bf6 18.Bg5 Bg7 19.Bh6 Bf6 1/2–1/2 (19) Brkic, A (2573)-Mamedov,R (2653) Sarajevo BIH 2010; b) 12.Nd5 Rfe8 13.Nxc6 bxc6 14.Nc3 Rcd8 15.Qd2 Bc8 16.Rad1 Nd7 17.Bd4 Nc5 18.Bxg7 Kxg7 19.Qe3 e5!= 0–1 (62) Mehar,C (2246)Kuzubov,Y (2626) Gurgon IND 2009; 12...Qh5 a) 12...Qc7?! 13.Bg5!

In the summer of 2013 I had not yet discovered the equalizing 10...Qd8! novelty, and I found myself struggling to meet the 7.Bc4 variation. I searched the database for some guidance, but to no avail. At the time I was simultaneously a Taimanov Sicilian player as well, and at some point it occurred to me that nobody plays Bc4 against the Taimanov, presumably because its scope on c4 is stunted by the e6 pawn. is led to the idea of meeting the Bc4 variation with an eventual ...e7-e6, and transporting ideas from the Taimanov such as ...a6-...Qc7-...b5-...Bb7-...Nc6a5(e5), and even ...Nf6-e8-d6. e process of developing this system has been some of the most enjoyable chess research I have

engaged in, and I am pleased to say it has resulted in a powerful and truly novel system. As the ‘prime mover’ of this project, my work is undoubtedly incomplete. ere are reams of unexplored possibilities, and I encourage readers to attempt their own contributions. e following chapters are by no means the nal — only the rst — word on this system. 7...0-0 8.Bb3 Black’s next few moves can almost be played automatically, irrespective of what White does: ...a6, ...Qc7, ...b5, ...Bb7.

From my experience playing this system over the last few years, most players, never having seen this system before, follow a safe course of castling kingside as White usually does in the 7.Bc4 system. However, in this particular system, White castling kingside leads to easy equality for Black, which I take to be a signi cant practical upshot of this system. We will postpone our discussion of White’s queenside castling until the next chapter. 8...Qc7 is move has been championed by Grandmasters Aronin, Pogorelov, and Balogh, also with the intention of expanding on the queenside, but they did without our core idea of ...e7e6. It is a matter of taste which move (8...a6 or 8...Qc7) is played rst; usually they will transpose. 8...Qc7 avoids 9.Nxc6 followed by 10.e5 since the e5 square is covered, but depending on your taste you might prefer to welcome the uncritical 9.Nxc6. When I came up with the idea of this system I was unaware of 8...Qc7, and for some (possibly arbitrary) reason went with 8...a6.

9.Ndb5 Qa5 10.f3 a6 11.Nd4 Qc7 transposes to our main line in the next chapter. 9.0-0 Although Black can choose whether to play 8...a6 or 8...Qc7, whichever he chooses on move 8 it is important to follow it up with the other on move 9 before embarking on 10...b7-b5. 9.h3 Qc7 As per protocol. 10.0-0 (10.Nxc6?! dxc6 11.0-0 b5 12.a3 c5 13.Nd5 Nxd5 14.Bxd5?!

Variations like this illustrate what I meant in the intrduction when I claimed that it often feels like you’re playing White when you play the Accelerated Dragon. A couple of careless moves by White and Black is not only equal, Black is already better. It is uncommon for White to be forced to play under such a slim margin of error as he must in this line.)

It turns out that Black can contain White’s kingside attack and solidify the center with ...e7-e6, and only then proceed with queenside and/or central counterplay. For his part, White must keep the attack going with urgency, because Black’s queenside counterplay is just a few moves away, and it will come with devastating effect (...Rac8, ...Rfd8, ...Na5, etc.). 12...Na5!?

is may turn out to be playable as well, but it is not in the spirit of the concept I am advocating. To allow White h4-h5 without immediate counterplay is akin to

the ordinary Yugoslav Attack in the Dragon; our aim is to play in ‘Taimanov style’ with ...h7-h5 and ...e7-e6. 13.h5 b4 14.Na4 (14.Nce2 Rfc8 15.hxg6 Nxb3+ 16.Nxb3 hxg6 17.Nc5 Bc6 18.Bh6 Bh8∞) 14...Nxb3+ 15.Nxb3 Nxh5 16.Nb6 (16.g4 Nf6 (16...Ng3? 17.Qh2) 17.Nb6 Rad8 18.Na5∞) 16...Rad8 17.Na5² 13.g4

e character of the position demands that this be played. Timidity will not suffice; time is of the essence in the race to determine which of the ank attacks will succeed. My initial attitude towards this system was that I should delay ...e7-e6 for as long as possible, because I felt I would always have the option later on, and I thought there could be more useful attacking moves on the queenside such as 13...Na5 (which also guards the important d5-square). However, as I delved deeper into this variation, I realized that Black should keep the knight on c6 for a little longer to deter White’s Be3-h6. e result

is a rather peculiar middlegame ‘standoff’, where White cannot make progress with Be3-h6 until Black moves his knight from c6, but at the same time Black cannot make progress on the queenside until he does either. 13.Nxc6 is may look unnatural — and it is — but the ‘computer move’ which it is based on (14.Bd4!) is not to be underestimated. Black’s f6-knight is the MVP (most valuable piece) of his position, as without it, White’s g2-g4xh5 would be decisive. Fortunately, the f6-knight is difficult to get at, as 13.Bg5?? loses to 13...Nxe4. White’s 13.Nxc6 takes aim at Black’s f6-knight by paving the way for 14.Bd4. 13...Bxc6 (13...dxc6 Black does not quite equalize here. 14.Bc5 a5 15.a3 (15.a4 Ba6∞) 15...Rfd8 (15...b4 16.Na4 Ba6∞) 16.Qe3 Rxd1+ 17.Rxd1 a4 18.Ba2 Rd8 19.Rxd8+ Qxd8 20.e5 Nd5 21.Nxd5 cxd5 22.f4²) 14.Bd4

Fair warning is in order: what follows is a total mess. at being said, look closely and you will see that it is White who needs to be accurate and nd several (nontrivial) ‘only’-moves in order to survive the complications.

Like 13...Na5, this move also prevents White’s g4-g5 followed by Nc3-d5, but by keeping the knight on c6, White’s Be3-h6 is hindered. What follows is somewhat a game of ‘cat and mouse’ — White’s main resource of Be3-h6 is unavailable at present, and it is difficult to see how to continue the attack without that. Black would welcome White’s g4-g5, which locks up the kingside and directs Black’s knight to d6 via e8. On the other hand, Black’s queenside attack is stalled by the

fact that he can’t play ...Nc6-a5 without allowing Be3-h6. at being said, whereas White is at a loss for ways to improve his position, Black can place his rooks on the d-and-c (or b-) les and threaten both central counterplay and a queenside pawn storm. 13...Na5?!

Computers take some time to appreciate the power of this idea, but anyone who has studied the Yugoslav Attack will

know that White’s recipe is to, as Fischer said, “pry open” les to Black’s king, then “sac, sac, mate”. 15...e6! (15...Nxb3+ 16.axb3 b4 17.Na4 d5 18.Rg5! is is the point.

e aggressively inclined Black player may be in dismay — White is initiating dangerous threats like Rg5xh5, and Black’s counterattack seems far off. However, as Suba teaches in his book Dynamic Chess Strategy, “initiative is a psychological advantage”, so it is up to us as defenders to grant or deny this advantage to our opponents. e aggressor is not better simply by virtue of being on the offensive: White was the rst to initiate action but if we defend well, he may quickly run out of steam and be left with no attack and static pawn weaknesses. 16...Kh7!

Maroczy was one of the best players in the world in the early 1900s, and was even set to play a World Championship match with Emanuel Lasker in 1906, but for various political reasons the match did not end up taking place. He was an engineer by training, and a nancial auditor by profession. Capablanca, near the end of his life in the early 1940s, said of Maroczy that “with the exception of Botvinnik and Keres, Maróczy in his time was superior to all the other young masters of today.” Maroczy popularized White’s setup in his capacity as a chess journalist, but there are no published games of his where he played the system with White. In fact, the rst recorded game in the Maroczy Bind is Swiderski-Maroczy, 1904, where Maroczy defended the Black side of the Accelerated

Dragon against the (to be named) Maroczy Bind. In order to combat the Maroczy Bind, Black must follow a darksquares strategy. Notice that in asserting the central c4/e4 ‘clamp’, White has forever denied the (dark) d4-square protection from a pawn. We will see in the subchapter 3 that the Breyer Variation is based on seizing this square from White’s grip. In keeping with the dark-squares strategy, exchanging dark-squared bishops is in general congenial to Black. In fact, GM Tiviakov once highlighted the importance of this exchange by playing the highly creative, though slightly dubious, 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 g6 5.c4 Bh6!?. 5...Nc6 6.Nc2

is is not the most challenging line for Black, but since it has been played by Keres, Tal, Korchnoi, and Carlsen, it has earned our serious attention. White usually waits for Black to play ...Bc8-d7 before retreating this Knight, because Black’s two most common ways of countering Nc2 are either a) ...Nf6-d7-c5, often capturing on c3 with the g7 bishop (an option made available by White’s departure from d4), or b) ...Bc8-e6 (which

is not recommended when White’s knight is on d4) and quickly targeting the c4 pawn with ...Ra8-c8, ...Nc6-e5, etc. e latter of these plans will be covered when we discuss the ‘Main Line’ Maroczy. Here I will go over two additional systems for the reader who wishes to take advantage of White’s premature retreat. 6...Nf6 7.Nc3 0-0 8.Be2 b6 e double- anchetto is particularly adept at meeting White’s Nd4-c2. With the knight on d4, a reliable way to meet Black’s double anchetto is with Nd4xc6, which is not possible here. 9.0-0 Bb7

Black intends to continue with the at rst glance unbelievable, but in this book thematic, ...Nf6-e8-d6, followed by ...f7f5. 10.f3 10.Bf4 is deters Black’s ...Ne8-d6 idea but after ...Nf6-e8 Black may instead gain a tempo on the f4-bishop after ...Ne8-c7-e6. Also, White’s f4-bishop is under X-ray attack from Black’s f8 rook after an eventual ...f7-f5. 10...Rc8 11.Ne3 Ne8 12.f3

Black will continue with ...Ne6-d4, ...e7-e6, and eventually ...d7-d5.; 10.Bg5 Not the most popular, but quite possibly White’s best. 10...Ne8! (10...Rc8?!

16.Nxf5 Rxf5 17.Be3 Rc8 18.b3 Black cannot allow White to coordinate like this, because Black has made antipositional moves and he can only get away with them if he plays energetically enough to prevent White from ‘achieving harmony’. erefore, Black lives and dies by the power of his counterplay: here, unfortunately, Black has capitulated control over the center, and is consequently unable to achieve the desired ...d7-d5. 18...Nf7 19.Rad1 Nd6 20.Bd4²) 13.exf5

Both recaptures on f5 are interesting, but my analysis indicates that 13...Nxf5 is the better of the two. 13...Nxf5 (13...Rxf5?! 14.Bh6! is move, which is all too easy for White to nd, makes life difficult for Black. From a broader perspective this should not surprise us: by exchanging pieces White dulls Black’s counterplay, which is Black’s only compensation for his hanging central pawns and multiple weaknesses.

Irrespective of where White moves his bishop, Black will continue with ...e7-e6 and ...d7-d5.

e idea of this move occurred to me while I was analyzing the ...Ne8-d6 maneuver in the 6...Nf6 line, where Black often plays ...f7-f5 and recaptures on f5 with the knight. I wondered whether Black could reach similar positions and save some time by taking the route Ng8e7-f5 rather than Ng8-f6-e8-d6-f5. I was also aware of similar ideas with colors reversed in the English opening, such as after 1.c4 e5 2.g3 Nf6 3.Bg2 d5 4.cxd5 Nxd5 5.Nc3 Nb6 6.e3!? or 1.c4 c5 2.Nc3 Nf6 3.g3 d5 4.cxd5 Nxd5 5.Bg2 Nc7 6.e3!?. Black’s basic idea is to go for a quick ...f7-f5, and then recapture on f5 with the knight, from

where it controls the important d4 square and also often pressurizes White’s e3 bishop. White can take one of (at least) two strategies: either try to develop normally and hope that Black’s offbeat play will lead to static positional weaknesses in the middlegame, or White can aim for a refutation of the system with an early h2-h4 or Bc1–f4-d6. According to my analysis, Black equalizes in all variations. 1.e4 c5 2.Nf3 g6 3.d4 cxd4 4.Nxd4 Bg7 5.c4 Nc6 6.Nc2 e6! 7.Be2 7.Nc3 Nge7 8.Bf4 is is the most obvious way to counter Black’s setup — planting a bishop on d6.

e Breyer variation of the Maroczy is characterized by Black’s 7...Ng4. Unlike the Maroczy Bind (5.c4), which was never played by its namesake Geza Maroczy, the Breyer variation was indeed rst played by Gyula Breyer in Kostic-Breyer, Gothenburg 1920. It has since been entrusted for important games by World Champions Botvinnik (SmyslovBotvinnik, Alekhine Memorial 1956) and Kasparov (Ribli-Kasparov, World Cup 1988). 1.e4 c5 2.Nf3 g6 3.d4 cxd4 4.Nxd4 Bg7 5.c4 Nc6 6.Be3 Nf6 7.Nc3 7.f3 Qb6!

Computers generally tend to prefer White in the Breyer, but from my experience even 2600+ GMs nd it very uncomfortable to ‘play around’ Black’s d4 knight, which (invariably) leads them to mishandle White’s position. is line has a very Sveshnikov Sicilian feel to it. Fischer taught us that “you have to give squares to get squares”; Black has opted to relinquish control over the light squares (especially d5) in order to stake a claim over the allimportant d4 square. is is the rst signi cant branching point for White: he will either develop routinely with Bd3, 00, Qd2, etc., or he will attempt to immediately take advantage of Black’s weaknesses with 10.Nb5. We consider these options in the coming chapters, but we begin with an underrated sideline. 10.Be2 If this move is followed by routine development, then it lacks independent value, since White’s bishop is better placed on d3. However, there are some idiosyncrasies to this line if White combines Bf1–e2 with Nc3-b5.

10...0-0 10...d6 e reader can make life easier for themselves by playing 10...d6 in response to any of White’s major options, but since he can get away with it, it is at least symbolically more exible for Black to castle rst. 11.Nb5!

10...d6!N I refer to this as a novelty, even though (as we will see) I have played this move twice (and won both times!) in tournament play — in unpublished games against WGM Nemcova (2350) and IM Gorovets (2550). Black saves a crucial tempo by delaying ...0-0 which allows him to generate central counterplay one move sooner. is does not violate the laws of opening play; after all, White is not castled either. It is actually quite in line

with the advice given by American legend GM William Lombardy in his recent book: “Not only should one not rush to castle, but should delay that passive maneuver for as long as good judgment relates that there are more urgent, if only slightly better, tasks to accomplish”. 11.Nxd4 is is of course the rst line to check: presumably 10...d6 was never played because it was thought to lose a pawn in this way. 11.Be2!?

Our compensation becomes of a longterm nature with this move. White cannot exchange bishops without returning his extra pawn, so he has to look for ways to disentangle his pieces — starting with his king on e2. I suspect most players will not play the most critical lines for White here (it can’t be easy to if you have never seen this position before), so Black may pragmatically opt to just remember 13...Be5! and gure things out over the board from here. 14.f3

is position may not look equal; White does after all have a slight material advantage, but his rooks will be permanently tied down to the defense of the queenside pawns and therefore never able to get activated. e position is just a draw. 28.Kg1

e simpli ed nature of the position should not induce a comatose attitude. From Shereshevsky’s marveous book “Endgame Strategy” we are shown the plight of the passive defender; Black must be vigilant to avoid ending up on the wrong end of a masterpiece.

We continue to delay castling — Lombardy would be proud. e importance of the saved tempo is already felt: if 12...0-0 then we transpose into the 10...0-0 line and White is allowed 13.Bc4+=. It amazes me how good Black’s position is here: it is already ‘zeroes’ according to the computer, and if White makes the slightest inaccuracy (as both my strong opponents did) then Black is already better. Once again, this opening forces us to look past our intuitive, visceral response to each position, which might mislead us into thinking White is better here due to Black’s backward d-pawn and apparent lack of counterplay.

In my opinion this is White’s best move, but authors like Khalifman recommend 10.Nb5 because they claim that “White should straighten out the situation with the black knight on d4 at once. Should it be left unmolested now, it will be much harder to contend with it later.” 10...d6 11.0-0 0-0 White has many possibilities here, but Black’s play is fairly straightforward regardless. He will either play on the queenside with ...a7-a6 and ...b7-b5 or on the kingside with ...f7-f5 (and often he combines play on both sides). However, he should not rush with either of these plans, because that would give White something to respond to, while at present the onus is on White to reveal how he plans to improve his position.

Black’s counterplay will take root in either (or both) ...f7-f5 or ...b7-b5, but suppose for a moment that Black ‘does nothing’ — what will White do? ere are basically two plans at White’s disposal that Black must constantly be prepared to meet: White will either aim for Nc3-e2 or go for f2-f4. Black generally has three ways of meeting Nc3-e2: capture on e2, ignore it and play ...b7-b5, or retreat ...Nd4-c6. Which of these Black plays will depend on the concrete timing of White’s Nc3-e2; sometimes all three options are viable for Black. In response to f2-f4, Black will either (and not both this time) play ...f7f5, or he will capture on f4 and re-route his knight from d4 to e5 via c6. Of course, Black should not ‘do nothing’; he should remain exible so as to be able to play either ...f7-f5 or ...b7-b5 depending on what White does. Black’s a8 rook will either be placed on c8 or b8. Black’s Queen usually goes to d7, but as we will see it can also nd a home on e7,c7, or a5. An important disclaimer is in order before

we continue: computers favor White by approximately +0.4 in most lines. However, when one presses the computer to formulate a plan, it is totally at a loss: while maintaining its += evaluation, it recommends shifting White’s pieces back and forth aimlessly. So, my point is, do not be discouraged by the engine’s prejudice — it has similar biases against the King’s Indian and other respectable openings as well. 13.Rad1 13.Rac1 a6

I was pleasantly surprised to come across this very rare idea in a book on pawn structures by Andy Soltis. Soviet (grand) masters of the 1950s and 1960s like Simagin, Bagirov, Aronson, and Veresov developed some truly original ideas in this system. Even if their crafty maneuvers are ultimately ‘too good to be true’, it is instructive to play over their games to get a feel for this system. Black plans to continue with ...Bc8-b7, ...Rf8e8, ...Ra8-c8, followed by ...Bf8c5/...Nd4-e6, or ...Re8-e6-d6! I envy them for playing chess in the pre-computer era; the analysis of this variation must have brought them such joy. Computers do spoil the fun a little, but there is no clear refutation of the idea either.

Compared with the Breyer Variation, this line is far more nuanced and, frankly, difficult to play well (for both sides). As with all practical matters, the choice involves a tradeoff: the Breyer is easy to play for Black, but if White plays accurately (which very few are able to do in practice) then he can achieve a slightly more pleasant position (if you nd this state of affairs to be unacceptable, I recommend abandoning the Sicilian altogether in favor of the Berlin or Marshall). In this line Black’s counterplay is more reactive in nature — Black can’t just ‘wear a blindfold’ and proceed with a plan on autopilot, but in return Black can count on dynamic equality and a tense

struggle where all three results are on the table. 9.0-0 ere are many ways to play this position for Black, but the main tabiya involves Black playing (in various move orders) ...Bc8-d7, ...Nc6xd4, ...Bd7-c6, ...a7-a5, ...Nf6-d7-c5. e question of move order is an important one for Black here: should Black start with 9...Bd7 or rst play 9...Nxd4 10.Bxd4 Bd7? In practice they usually transpose, because most White players are unwilling to play a different line against each of these, preferring instead to enter the Qd2 main line regardless of Black’s move order. at being said, according to my research, 9...Bd7 is the signi cantly better move order (and it is introducted in the next chapter), in light of 9...Nxd4 10.Bxd4 Bd7 11.Qd3!. 9...Nxd4 10.Bxd4 Bd7

11.Qd3! is is not a new move, it was rst played in Smyslov-Pirc 1956 (1–0); for some reason it has not caught on. I owe Kevin Spraggett for revealing its strength to me. White’s basic idea is to

prophylactically defend the e4-pawn so that ...Bd7-c6 can be met with b2-b4! White usually wants to wait for Black’s bishop to be on c6 before playing b2-b4, because the weak c4-pawn is under less pressure when Black’s bishop is on c6 as opposed to e6. In general Black wants to prevent White from playing b2-b4 (at least) until his knight has landed on c5, so the central theme of this variation is White trying to achieve b2-b4 and Black trying to either prevent it or render it premature. Unfortunately, nothing seems to work for Black. I will present the following lines without comment, because I am recommending we avoid this altogether, but I encourage the reader to try to nd improvements on my analysis, and to at least skim through the ensuing variations to get a feel for which positions are playable for Black and which are to be avoided. 11.b4 Be6 12.f3 Nd7 13.Nd5 Bxd4+ 14.Qxd4 Bxd5 15.cxd5 a5 16.a3 axb4 17.axb4 Rxa1 18.Rxa1 Qc7= 11...a6!?

e downside of this line is 10.Nc2, whereas the downside of the 9...Nxd4 move order is 11.Qd3! In my judgment we should prefer to allow White 10.Nc2 here. Let’s rst have a look at some side moves. 10.Nb3 e logic of this move is similar to 10.Nc2: since White has more space, he wants to avoid exchanges to keep Black’s position cramped. Furthermore, the ‘soft’ c4-pawn can be defended by Nb3-d2, as it often is by Nc2-a3 in the 10.Nc2 line. 10.Rc1 Nxd4 11.Bxd4

is move was a real headache for me to deal with when preparing this book. I did not have the luxury of recommending the usual 9...Nxd4 because I was in on the secret of Smyslov’s powerful 11.Qd3! e database games were not much help either; the consensus seems to be that Black must sit back passively and demonstrate resiliency in the face of White’s b2-b4 or f4-f4/g2-g4 expansions (see the alternatives to 10...Rc8 for an illustration). I analyzed all kinds of weird ideas for Black, like ...a7-a5/...Nc6-b4/...Bd7c6/...Nf6-d7-c5, but I realized that White’s position is too solid for Black to get away with unprincipled play. I concluded that if Black is going to be able to equalize in this line, it will be via ‘healthy’, thematic moves in the spirit of the opening.

Until around 2012 this was by far the most popular move, and it still is overall, but it has been absent from the top games in the last ve years, particularly in favor of 10...Qa5.

An important novelty. White is forced to make a decision of how to deal with the hanging c3-knight, and Black will respond accordingly.

Here, Black will consider relocating his h5 knight to c5, or perhaps instead he will relocate his g7 bishop to a7 and keep the knight on f6. Eventually things will zzle out: White will play Nd5, Black will take it with either knight or bishop, and rooks will get exchanged on the c- le. As always, Black’s counterplay is to be found in ...f7-f5 or ...b7-b5.; b) 13.Bd2 Qb6 14.Nd5 Nxd5 15.exd5 f5„; 13...b5!

is is one of the few times in the book where I’ll give White a slight advantage in a main recommendation. e reader should be suspicious of authors who claim pure equality in all lines in anything other than the most topical lines of the Ruy Lopez or perhaps the Najdorf Sicilian. is is the sort of += we have to live with as Accelerated Dragon players. White played very well to get here; he had to navigate his way around many landmines. After all that, we can seek consolation in the fact that objectively speaking, there are only three results in chess, and ‘+=’ is just short-hand for ‘= after accurate play’. e onus is on White to improve his position; Black can shift his pieces around until White makes a concession. For example, if

White goes for g4-g5, then Black may relocate his knight to c5 via d7, and place

his bishop on e5, perhaps combined with ...Qa5-b4.

Here White’s main alternative to 12.f3 is 12.Bd3. 12.Bd3 A move rst played by GM (and now professor of economics at Harvard) Ken Rogoff against Bent Larsen in 1976. By abstaining from f2-f3, White intends to meet ...Nf6-d7 with the exchange of dark squared bishops, followed by the rook lift Ra1(f1)-e1–e3-h3, threatening Qd2-h6. 12.Rfd1 e5 13.Be3 Nxe4 14.Nxe4 Bxe4 15.Qxd6 Qh4=; 12.Qe3 e5 13.Bxa7 Nxe4!N 14.Nxe4 Bxe4 15.Rfd1 Bc6! 16.Bc5 dxc5 17.Rxd8 Rfxd8= I’d rather be Black: ...e5-e4 and ...Bg7-d4 are to follow.

12...Nd7 12...a5 It is hard to say which move order — 12...a5 or 12...Nd7 is more accurate. In practice neither is because they will quickly transpose. 13.b3 Nd7 14.Be3 Nc5 transposes to 12...Nd7. 13.Bf2!? is is only played about 6% of the time, 13.Be3 being by far the most popular (80%), and 13.Bxg7 second most (13%).

e rst stage of Black’s plan is complete. Far and away the most common (nearly 80% of the time) way to continue for Black is with the spectacular, if unbelievable ...Qb6, ...Rfc8, ...h5, ...Qd8, ...Kh7, and ...Qh8 with pressure on the long diagonal. is is the line I mentioned early in the book, which Mamedov suggested was equal. Playing this plan on autopilot has its appeal, but because of its extravagance most White players are aware of it nowadays, and will not be caught off

guard. e line I recommend in lieu of this is, in contrast, quite rare (it is played only about 8% of the time, but it has been growing in popularity) and in my judgment equally sound, but with far greater surprise value. e idea is to ght for the center with ...e7-e6 and ...Bg7-e5, ideally followed by ...f7-f5. Black’s bishop is rather safe on e5, because White can scarcely achieve f3-f4 without losing the e4-pawn. White tends to focus his attention in one (or more) of three directions: either he will directly target the weakness on d6 that Black creates after ...e7-e6, or he will try to achieve f3-f4 which indirectly targets d6 by hitting its defender (the bishop to be on e5), or as always White can ‘ignore’ Black’s central gestures and continue with the usual a3/b4 queenside expansion. 15.Rab1 is is by far the most popular move, played nearly 90% of the time. 15.Rfc1 Be5 (15...e6!?

A point made by GM Rowson in his book Chess for Zebras: a pawn on f4 weakens the king in a way which should not be underestimated.

I rst came across this move when Cuban GM Abreu seemed to come up with it over the board against me after a long think in the game I mentioned in the introduction of this book. However, he was not the rst to play it; that honor goes to the late Bulgarian GM Georgi Tringov who played it in 1986.16.Bd1 is a perfectly logical move: the bishop will relocate to c2, from where it simultaneously bolsters the critical e4, b3, and a4 squares. White already threatens

17.a3 since the knight cannot hop into b3 after 17...a4 18.b4. In the last few years, 16.Bd1 has been played more times than it has in all previous years combined. I think the most common move, 16...Be5, does not equalize for Black, but 16...Qc7 does. It makes sense too — Black targets the c4-square which has been abandoned by the relocation of the e2-bishop. I thank IM Dave Ross for suggesting this move to me. 16...Qc7! is move is a good illustration of the aforementioned ‘reactive’ nature of Black’s play in this line. White relocates his bishop to c2, so Black targets the c4-pawn with his queen, and in some lines with his knight by relocating to e5 via d7. a) 16...f5?! 17.exf5 gxf5 (17...Rxf5 18.Ne2± 1–0 (43) Tringov, G-Haik,A Vrnjacka Banja 1986) 18.Bc2 f4 19.Bf2 Qg5 20.Kh1 Be5 21.Rfe1 Qg7 22.Ne2 b6 23.Nd4 Bb7 24.a3 Rf6 25.b4 Nd7 26.Nb5 Kh8 27.Bg1 axb4 28.axb4 Rg8 29.Re2 d5 30.Rbe1 (¹30.cxd5 Bxd5 31.Bb3 Bxb3 32.Rxb3±) 30...dxc4 31.Nd4 Rh6 32.Rxe5??

e database reveals that it was Danish IM Jan Sorensen who introduced the idea of ...e6/...Be5 into tournament practice. In 1990 and 1991 he scored 1.5/2 against then IMs (now GMs) J. Kristiansen and A.

Fishbein.

e Hyper Accelerated Dragon move order (2...g6) avoids the Bb5 Sicilian at the cost of allowing 4.Qxd4 here. In my opinion, the tradeoff is very much worth it: the Bb5 Sicilian is a real buzzkill for the dynamic and ambitious Black player, whereas the 4.Qxd4 line is for the most part rich in dynamical possibilities and offers Black real chances to play for a win. 4...Nf6 5.Nc3 We cover White’s main move, 5.e5, in the next subchapter. is line has some venom, and in my judgment Black does not equalize in the most popular way of dealing with it. 5.Bb5 I have faced this move several times in online blitz but never over the board. It’s basically just a cheapo attempt: if Black plays 5...Bg7 then 6.e5! is strong for White. However, this unrespectable move actually has, according to Donaldson and Silman, a highly respectable originator — David Bronstein. 5...a6 (5...Bg7? 6.e5±) 6.e5 is can be a little scary the rst time you see it, but it’s just a bluff by White.

9.Nxd7 Here 9...Qxd7 is the most popular move by a 6:1 margin but it looks to me that Black struggles to equalize there. Giving up the two bishops is already a concession Black has to live with in this line; he should rush to nish his development with 9...Nxd7 rather than spend several tempos on queen moves as he must after 9...Qxd7. 9.Nxc6 Donaldson and Silman give this as += however... 9...Qb6!N A nice little novelty which renders 9.Nxc6 harmless.

ANTI-SICILIANS: ALAPIN AND MORRA 1.e4 c5

after 1.e4 c5 2.Nf3 g6: the Alapin, also known as the c3-Sicilian, and the Morra Gambit, also known as the Esserman Gambit. e Alapin can be played on move two (1.e4 c5 2.c3) or on move three (1.e4 c5 2.Nf3 g6 3.c3), so for convenience and consistency I recommend a line for Black which works against either of these. e Morra Gambit (1.e4 c5 2.d4 cxd4 3.c3 or 1.e4 c5 2.Nf3 g6 3.d4 cxd4 4.c3), a sister to the Alapin, has recently seen a revival, especially at the club level, thanks to the publication of IM Esserman’s masterpiece “Mayhem in the Morra”. 1.e4 c5 2.d4 cxd4 3.c3

Here we have the Morra Gambit, a system emblematic of the Romantic Era in chess — not chronologically, but in spirit:

“e masters of that time found a sound and fruitful plan: disregarding pawns, achieve a rapid development of the pieces for a swift attack on the enemy king. “ (World Champion Emanuel Lasker). On Steinitzian grounds one might insist that the principled continuation for Black is to accept the gambit — “the best way to refute a gambit is to accept it”. However, there is a hidden premise in this assertion: the gambit must be refutable! It is not at all clear to me that the Morra Gambit is refutable; on the contrary, Esserman’s aforementioned book is a convincing defense of its soundness. Furthermore, as Hyper Accelerated Dragon players we offer White the option of a ‘delayed’ Morra Gambit 1.e4 c5 2.Nf3 g6 3.d4 cxd4 4.c3 after which our options are far more limited. As best I can tell, Black cannot safely accept the delayed Morra Gambit, so for the sake of consistency I recommend declining after 1.e4 c5 2.d4 cxd4 3.c3 as well. e usual way to decline the gambit is to transpose to the Alapin with ...Ng8-f6, but this is not in keeping with my recommended Alapin repertoire. Fortunately, the ...d4-d3 line is a reliable way of transposing into Maroczystructures which we are familiar with and happy to play as Black. I cannot overstate how frustrating it is for Morra Gambit players to be denied their Romantic fantasies and instead be lulled into a slow, maneuvering Maroczy structure. 3...d3 4.Bxd3 g6 5.c4 Bg7 6.Nf3 d6 7.h3 Nf6

If Black wants to play my idea, then White must not be permitted to recapture on c3 with the queen, so Black must play ...Bxc3 before White achieves Bc1–e3 and Qd1–d2. (8...0-0 9.Be3 Nfd7 10.Qd2 is is of course playable for Black but not in keeping with our theme.) 9.Be3 Bxc3+ 10.bxc3 Ne5!

In a similar position, Esserman cautions that White should not allow “the queen’s knight to be lopped off by the swooping ...Bxc3 wrecking the pristine Maroczy structure...Black’s dark squared de ciencies are overshadowed by White’s mangled formation.” Here, however, White does not have much of a choice: Black is ready to capture on c3 and White’s only ways to prevent it are rather contrived. 9...Nc6 Black’s most popular move, but in my judgment it is insufficiently sensitive to the time factor in the position. White does, after all, have more space, so he will go on to have a more comfortable position (‘achieve harmony’) if Black is unable to pose any disruptive threats. 10.Be3 Nd7 11.Qd2 Nc5 12.Bh6!² Black should be able to defend, but White is playing for two results.

10.Be3 I think if White wants to attempt an opening advantage then this is his best hope. Allow the doubled pawns, and hope there is enough dynamic compensation. In researching this structure I have come to regard White’s attacking potential as quite formidable, even though computers tend to think that Black is equal ‘no matter what’. I recommend immediately aiming for simpli cations with 11...Ne5! to neutralize White’s initiative. 10.Bg5 Bxc3! 11.bxc3

11...Ne5 Computers take some time to appreciate this idea, but from a human perspective it is clear that exchanging pieces bene ts Black. is is because White’s compensation for his static pawn weaknesses must be predicated on dynamic piece play.

is is a concession — the bishop would prefer a more active square.

11...Ne5! I recall an interview with Aronian where he said (paraphrasing) that the greatest joy in chess preparation nowadays comes from nding ideas the computer is unable to immediately appreciate. at was certainly the case with this move. e computer’s suggestions all enabled White to develop a dangerous kingside attack, but I was looking for something requiring less accuracy from Black. e engine initially thinks that White is += after the exchange on e5, but the human realizes that either Black is getting into immediate trouble or he’ll successfully develop his pieces and be ne. If it is the latter, which it fortunately is, then ‘+=’ is not a very meaningful assessment. 11...Nc5?! 12.Bxc5 dxc5 13.e5²;

White’s attack is not devastating, but it’s just not very comfortable to be Black here. e position is reminiscent of lines in the Scaemish or Rubinstein Nimzo Indian where Black doubles White’s c-pawns and expends several tempos to win the c4pawn at the cost of allowing White an f4f5 attack.; 11...Na6

is move ts with Nimzowitsch’s philosophy of blockade: “First restrain,

next blockade, lastly destroy”. Unfortunately, the ideal blockade is not always the most relevant aspect of a position, and I believe Black’s rst priority should be to avoid a kingside onslaught by liquidating with 11...Ne5! 12.Bc2 Nac5 (12...f6 13.Nd4 Nac5 14.Bh6 Re8 15.f4 Kh8 16.h4 Rg8 17.Re1 Nb6 18.e5 dxe5 19.fxe5 Nxc4 20.exf6 exf6 21.h5±) 13.Nd4 Re8 (13...b6 14.Nc6 Qe8 15.Bh6±) 14.f4 b6 15.f5 Ne5 (15...Bb7 16.Qf3 (16.fxg6 fxg6) 16...Ne5 17.Qf4 Kh8 18.fxg6 fxg6 19.Qh4 Kg8 20.Rad1²) 16.Nf3 Qc7 17.Qe1 Nxc4 18.e5∞

If we accept Euler’s estimation of the value of the pieces, then the material is numerically equal (three pieces for a

queen). However, in chess (and in many spheres of life) there is a phenomenon whereby the whole is greater than the sum of its parts. My father used to refer to this as ‘cooperation points’: for every combination of pieces, add a point, so two pieces are worth 3+3+1, ie. more than a rook+pawn (pawns don’t count as pieces) . Similarly, three pieces are worth 3+3+3+1+1+1. is may be a bit of an exaggeration, but it’s not a bad rst approximation. I suspect my father thought of this himself (in the context of a variation in the Pirc where three pieces outshine a Queen and two pawns), but I also came across the idea in Lasker’s Chess Manual. 4...g6

e rst strong player to consistently play this move was Yugoslavian Grandmaster Ognjen Cvitan, who played it several times throughout the 1990s. Since then, the move has found a brigade of supporters, most notably Radjabov, Karjakin, Dreev, and Almasi. It was also played several times by a young Magnus Carlsen. 5.dxc5

5...Nc6!? In this book I have tried, where possible, to present novel ideas, even where the accepted wisdom is perfectly adequate. ere is value in exploring new terrain, both from a scienti c perspective of enriching the literature on an opening, but also from the practical, ‘surprise value’ perspective. 5...Nc6 is an extremely rare move, about fty(!) times less common than the main move, 5...Bg7. I am not sure, nor do I frankly care very much, which of 5...Bg7 or 5...Nc6 is ‘objectively’ the better move. It seems to me though, that the new ideas which follow lead to rich, unexplored positions where a wellprepared Black player can pose serious problems for their opponent. Praxis and the test of time will determine whether these ideas have wings, or whether Black is better off adhering to the usual 5...Bg7. Before continuing I would like to mention

that the following is joint analysis between myself and Canadian (exiled by marriage to America) IM Dave Ross. 5...Bg7 e reader may consult GM Ftacnik’s book on the Sicilian for his treatment of this move. Black may be ne with accurate play, but the amount of awkward queen moves Black is lured into is not to my taste. 6.Nbd2!

One of the nice things about this 5...Nc6 system is that it is particularly well-suited to meet 6.Na3, which is the most popular move against 5...Bg7. Indeed, when I was practicing this line in online blitz I came across Alapin specialist GM A. Zhigalko and 6.Na3 was his choice as well. As we see, though, Black’s 5...Nc6 enables him to quickly castle queenside and pose White with immediate problems. 6...Bg4 7.Nb5 (7.Be2 cxd4 8.cxd4 Nf6 9.Nb5 Rc8 10.Nc3 Qa5 11.d5 Rd8 12.0-0 Bg7³; 7.Bc4 Bxf3 8.gxf3 Qf5„ It is a great practical upshot of this system that natural moves by White allow Black to equalize with ease. 9.Bd3 Qh5 10.Be4 Nf6 11.Nb5?

White is suddenly caught off guard — Black isn’t supposed to be able to castle queenside in this opening! Reap the rewards of 5...Nc6. Black has taken over the initiative and White needs to be extremely accurate to not lose outright in the next few moves. 8.Be2™

Black is down a pawn, and will likely stay down a pawn for the foreseeable future, but as compensation he has better control over the center and the potential to harrass White’s king which has lost its castling rights.

is move order is recommended by GM Sveshnikov in his book ‘e Complete c3 Sicilian’ as particularly effective against the system I am recommending against 2.c3. White’s idea is to delay d2-d4, so that after 3...d5 4.exd5 Qxd5 White has the option of 5.Na3, considered better for White by Sveshnikov. Black has two ways to transpose to the main line of this chapter: either play 3...d5 and allow Sveshnikov’s 5.Na3, or play 3...Nc6 and allow a ‘delayed’ Rossolimo (4.Bb5). According to my analysis, either of these is ne for Black, but 3...Nc6 is more in keeping with my recommended repertoire for reasons I will make clear in this subchapter. 3...d5 4.exd5 4.Bb5+ is effectively leads to a forced draw, which may be (for some) another reason to prefer 3...Nc6. 4...Bd7 5.Bxd7+ Qxd7 6.Ne5 Qe6 7.Qb3!?

Sveshnikov is quite optimistic about White’s chances: “White develops quickly and takes a rm grip on the initiative”. 5.d4 Nc6 is transposes to the main line

of the Alapin (2.c3 d5 3.exd5 Qxd5 4.d4 g6 5.Nf3 Nc6). 5...Bg7 6.d4 is transposes to 1.e4 c5 2.c3 d5 3.exd5 Qxd5 4.d4 g6 5.Nf3 Bg7 6.Na3, and I think it is ne for Black. However, I recommend (in the main line of the Alapin section) that Black plays 5...Nc6 instead of 5...Bg7, so this variation does not ‘come up’ in the main move order. at being said, I recommend 5...Nc6 because I don’t like Black’s position after 5...Bg7 6.Nbd2! which is not the case here, so some readers may prefer to allow this line rather than allowing a delayed Rossolimo with 3...Nc6. 6.Bc4 is is Sveshnikov’s recommendation (following up with: 6...Qe4+ 7.Be2). 6...Qe4+ 7.Be2 a) 7.Qe2 Qxe2+ 8.Bxe2 (8.Kxe2 a6!=) 8...Nf6 9.d4 (9.Nb5 Nd5=) 9...cxd4 10.Nxd4 0-0 11.0-0 Rd8 12.Rd1 Bd7 13.Bf3 Nc6=; b) 7.Kf1 Be6 8.Be2 Nc6 9.Ng5 Qf5 10.Nxe6 Qxe6 11.Qb3 Qd7=; 7...Nf6 8.0-0

I’ve seen some grandmasters in America play this line against lower rated players in Swiss tournaments presumably to obtain winning chances but in my view White is

playing with little risk: the isolated pawn is inadequately blockaded, so it can always be pushed if White is content to neutralize the position. 12.Rae1 12.Nb5 Nc6 13.Nc3 (13.Bd3 Qd5 14.Qa3 Nxe3 15.fxe3 Qd8=) 13...Qg4 14.Be2 Nxe3 15.fxe3 Qh5= 12...Nxe3 13.Rxe3 13.fxe3 Nc6= 13...Qf4 14.d5 exd5 15.Bxd5 Na6 16.Rc1 Qf6=

I prefer this move order, because I quite like the delayed Rossolimo (4.Bb5) for Black, especially if it is an Alapin player on the White side. 4.Bb5 is transposes to a harmless variation of the Rossolimo: 1.e4 c5 2.Nf3 Nc6 3.Bb5 g6 4.c3. 4.d4 d5 5.e5

Aside from transposing to the main line of the Alapin subchapter with 5.exd5, this is White’s only serious attempt at playing for an advantage. However, I prefer Black in the tense struggle which ensues. (5.dxc5 is offers White no advantage whatsoever. 5...dxe4 6.Qxd8+ Nxd8 7.Nd4 Bg7 8.Bb5+ Bd7 9.Bxd7+ Kxd7 10.0-0 Nc6 11.Rd1 Nxd4 12.cxd4 f5 13.Nc3 Ke6! 14.d5+ Kf7=; 5.exd5 Qxd5 is transposes to 1.e4 c5 2.c3 d5 3.exd5 Qxd5 4.d4 g6 5.Nf3 Nc6.) 5...cxd4 6.cxd4 Bg4 Black has ideas of ...Qd8-b6, ...Ng8-h6-f5, etc. e position plays itself. 7.Be2 a) 7.Nbd2 Nh6 8.h3 Bxf3 9.Nxf3 Nf5 10.Qa4 (10.g4 Ng7=) 10...a6 11.Bd3 Qd7 12.Bxf5 Qxf5 13.Qb3 Qd7=; b) 7.Bb5 Qb6 8.Bxc6+ Qxc6 9.0-0 e6 10.h3 Bxf3 11.Qxf3 Bg7 12.Nc3 Ne7 13.Bg5 Nf5 14.Ne2 h6 15.Bd2 0-0=; 7...Nh6 8.Nbd2

I very much like this move, which grew up in the 1960s in the arsenals of grandmasters Mednis, Taimanov, and Pirc. Black demands a decision from White, and the ‘wasted’ tempo on ...a7-a6 is not really a waste when we consider that White rarely couples Bb5xc6 with c2-c3 in the Rossolimo. 6.Bxc6 6.Ba4 b5 7.Bc2 d5 8.d4 cxd4 9.cxd4 Bg4= 6...dxc6! White wishes the c-pawn were on c2; on c3 it obstructs the natural square for the knight, and also weakens the d3-square. e only way for White to make sense of his position is to play for d2-d4. 6...bxc6 7.d4 cxd4 8.cxd4 Nf6 9.Nc3 00 10.Re1 d6 11.h3 Rb8 12.Qc2 Qb6 13.b3² 7.d3 7.h3 Qd3! 8.Re1 Nf6 9.Re3 Qd8 10.d4 0-0 11.Nbd2 cxd4 12.cxd4

A thematic idea for this structure: Black has his eye on the to-be d5 hole after an eventual ...f7-f5.
