S113.2 Alekhine Voronezh Variation ΑΙ 7.14 Blackmar-Diemer Gambit νο 16.10 Slaν Botνinnik Variation SL 7.8 Nimzo-Indian 4.'iYc2 d5 Ν123.3 ΕνθΓ since the Theory Forum was introduced ίη Yearbook 39 (way back ίπ

1996), two opening lines (SI 13.2 and SL 7.8) have been involved an exciting battle for the title of Most Discussed Variation. It is probably going to be a photo finish, but at the present moment it seems that S113.2 (Najdorf 6.~c4) may just have its nose ίη front, thanks to Valentin Stoica's extensive reaction to lan Rogers's discussion of Pedzich-Maciejewski ίπ Yearbook 41. ΗοννθνθΓ, the Slav Botvinnik, SL 7.8, is running a close second with Sergey lvanov's mammoth analysis of his fascinating game against Aseeν, with which he continues his argument from the previous Volume, aiming to show that earlier reports of the death of the Botvinnik Variation are much exaggerated. Far outdistanced by the two front runners, the rest of the field consists of three more contributions. Jeroen Noomen argues that the Blackmar-Diemer is eνθη better for Black than was already thought, Maher Saleh of Canada has discovered an improvement for Black ίη the Voronezh Vaήatίοn of the Alekhine and Jan Timman refutes Hillarp Persson's deviation from Sosonko's analysis of ΝΙ 23.3 ίη Yearbook 34. ίπ

Rauzer νθΓίθΙίοn

It has become virtually impossible to keep υρ with deνelopments ίπ the Rauzer Variation. Α survey featuring the position after White's 11th move was recently published ίπ Yearbook 41, but an update has already become necessary. Ιπ Yearbook 41 Lev Gutman could still write about Ά Big Success for Black', and a reply from the supporters of the white side was bound to appear. Ιπ Linares, Vladimir Kramnik introduced the novelty 17 ... J:ιb8 ίπ his game against Alexey Shirov, who was so impressed that he awarded the move double exclamation marks. Gary Kasparov, however, kept his cool and managed to wrest a clear advantage with 18.c3!. There is also some news to report about 12.~θ2, which yielded Shabalova win oνeΓ Serper. Nonetheless, 12.~d3 was the most important moνe until recently, and as the examples show, it can lead to great complications. Other alternatiνes are not considered ίπ this survey. This means doing an injustice particularly to 12.1fe3, a move that has also seen some interesting recent developments, οπ which we hope to report another time.

SiciIian Defence The 4...1fb6 System

The Unpleasant 7.'We2 Line Ιπ the basic position of the 4 ... 'Wb6 system after the introductory moves 1.e4 c5 2.ttJf3 ttJc6 3.d4 cd4 4.ttJd4 ~b6 5.ttJb3 ttJf6 6.ttJc3 e6 the continuation 7.'We2 is less frequently played ίπ practice compared to classic continuation 7.~d3 and 7.~θ3. Nevertheless, this unpleasant continuation, played with the idea of castling queenside quickly and starting the standard attack οπ the kingside g2-g4-g5 should by πο means be underestimated. The light-squared bishop developed along the a8-h1 diagonal won't be exposed and ννίll support the positional pressure οπ Black's position. Practice has shown that this system can be extremely dangerous for an unprepared opponent. After 7.~θ2 Black has the choice between two completely different systems. The continuations 7 ... §Le7, 7 ... ~c7 and 7 ... d6 lead to a more complex game and a type of position that resembles the Keres Attack ίπ a rather favourable version for White. White's space advantage is the dominant factor ίπ the position and it is not easy for Black to organize counterplay. This claim is most convincingly confirmed by those games ίπ which both sides castle queenside. Experts οπ the 4 ...'Wb6 system, such as Akopian, Anastasian and Avshalumov, had problems with this lίΠθ (see the section Study Material). The most reliable and flexible continuation is 7 ... ~b4. After 8.§Ld2 ο-ο 9.a3 Black again faces a choice. The older 9 ...~θ7 is playable but less ambitious than 9... ~c3. Ιπ several older games White managed to achieve a small positional advantage ίπ the main lίne 8.~d2 ο-ο 9.a3 §Le7 10.e5 ttJd5 11.ttJd5 ed5 12.0-0-0 d6 13.ed6 §Ld6. But the impressions remains that Black can keep the balance with accurate play. One of the critical positions for the whole system 7.'We2 arises after 9 ... ~c3 10.~c3 e5 11.0-0-0. Ιπ practice this position was played ίπ three games. The latest example is ουΓ featured game Adams-B. Knezevic, French Team Championship 1997, ίπ which White, after 11 ... nd8, played the novelty 12.nd6!, and by sacrificing the exchange

MARCIANO MARCIANO

Sicilian Defence Nimzowitsch νθΓίθΙίοn

The provocative 2 ... 4Jf6 is considered inferior by current theory but has scared some of the best players ίπ the world. Ιπ Kramnik-Seirawan, Amsterdam 1996, the Russian refused the fight by playing 3.4Jc3, allowing Black easy equality. Smirin also avoided the main lίΠθ against Bruk ίπ the 19961sraeli Championship by playing 5.4Je4. Were they right to avoid what is supposed to be the theoretical refutation? Let's take a look. After 5.4Jd5 ed5 6.d4 Black has three main lines. The most common continuation, 6 ...4Jc6 7.dc5 ~c5 8:ifd5 ~b6, forces White into complίcations. ΗοννθνθΓ if White plays all the right moves - moνes which are almost forced anyway - Ι think Black's position becomes νθΓΥ difficult to defend. The second try, 8 ... d6 9.ed6 ~b6, gives White a wider choice and thus also more chances of going wrong. Η οννθνθΓ, yet again, if he plays the best Iίne Ι think Black has compensation for only half a pawn and not the whole pawn which has been sacrificed! Finally, Black can try delaying 6 ... 4Jc6 with 6 ... d6 ΟΓ θνθΠ 6 .. :ti'b6, but statistically both are disastrous for Black (below 30%!) and White has many ways to obtain the advantage. Επ passant, it should be noted that neither 4 ... 4Jc3 ΠΟΓ 4 ... 4Jc7 give Black a pleasant position. ΜΥ conclusion is clear: this opening is νθΓΥ tricky but ίπ the end favours White, and Ι don't believe it ννίll be met νθΓΥ often at top lθνeΙ More generally Ι think 2 ... 4Jf6 is not really correct. .

Caro-Kann Defence Adνance νθΓίθΙίοn

15 Black ίn trouble? The popularity of the Caro-Kann Adνance Variation is subject to fluctuations. Sometimes years ννίll pass during which ηο grandmaster ννίll condescend to play the moνe 3.e5, while ίη other times it is played θνθη at the highest lθνel.

Ιη the early '80s, John νan der ννίθl and John Νυηη used to seize their opponents by the throat with 4.llJc3 and 5.g4. Ιη the '90s, Nigel ShoΓt and Viswanathan Anand ννθΓθ the principal champions of the Adνance Variation, although they preferred the positional 4.llJf3 to the berserk tactics of 4.llJc3 and 5.g4. Boris Gelfand has also been seen to use the νariation as White, against ηο less a person than the pre-eminent Caro-Kann specialist Anatoly Karpoν ίη their Candidates' match, Sanghi Nagar 1995. Ιη the hands of grandmaster Vladimir Epishin, who acted as Karpoν's second ίη the Sanghi Nagar match, the Caro-Kann seems a νθΓΥ hard nut to crack, the three-times Russian champion Peter Sνidler also haνing failed so far to make a dent ίη Black's defensiνe Iines. Currently the attempt 8.~g5, introduced by Kνeinis, seems to be White's best bet; Black has to watch his step νθΓΥ carefully to aνoid slipping into an inferior position. The question we would Iίke to see answered is: Is Black ίη trouble after 8.~g5 ΟΓ is his fortress strong enough to weather the storm?

Scandinavian Defence Portuguese Variation

grandmasters and Ieading theoreticians have aIways had a strict ranking of openings. Οπ 1.e4 the Scandinavian was never ranked highIy because of the basic ruIe saying that one shouId πο! waste time with queen moves ίπ the opening, as this wouId ΟΠΙΥ heIp your opponent's deveIopment. Because of the simiIarities of the pawn structure, 2 ... 'ii'd5 is sometimes caIIed an inferior Caro-Kann. 2 ... ttJf6 has aIways been even Iess popuIar amongst theoreticians, but what about 3.d4 iιg4? Enough Ιο make their hair stand up, certainIy. Η oweveΓ, some taIented young pIayers ίπ PortugaI (and earIier ίπ BeIgium) took a cIoser Iook at this line, and as they were ποΙ prejudiced they found many interesting new ideas. The contributions of CarIos Santos and others turned GM Spraggett, who Iives ίπ PortugaI, ίπΙο an adherent of this variation. EarIier this year he pubIished an articIe οπ ί! ίπ the Canadian magazine En Passant. The main repIy Ιο the naturaI4.ttJf3 is 4 ... 'ii'd5. 4 ... ttJd5 Ieads Ιο the main Iines anaIyzed by GM GipsIis ίπ ΥΒΙ37. 4 .. :ifd5 is connected with a quίck ttJc6, foIIowed by 0-0-0, giVΊng the game a sharp character. Οπ 5.~e2 ttJc6 6.ttJc3 the wideIy recommended 6 ... 'ii'f5 seems dubious οπ account of 7.d5!, see Hjartarson-GaIego, but there is nothing wrong with 6 ... 'ii'h5, as ίπ Cao-Damaso. 4.iιe2 is Ιοο passive Ιο refute the variation. After 4 ...iιe2 5.'ii'e2 'ii'd5 6.ttJf3 the correct reply is 6 ... e6!, defending against the push d4-d5, and after castlίng ίπ opposite directions Black has good tacticaI counterchances, see Kouwenhoven-Hodgson. 4.f3 is the fundamentaI answer, but this is also the move tacticians are waiting for. 4 ...iιf5 5.c4 e6! 6.de6 ttJc6! is a beautiful idea, casting a speII οπ many pIayers searching for bIood οπ the chess board. Ιπ Burovic-Monange BIack got everything he could possibIy have expected from the opening, and Campora-Ribeiro and MainkaSariego gave birth ιο immense compIications. 5.iιb5 ttJbd7 6.c4 is again met by the pawn sacrifice 6 ... e6!, when

Alekhine Defence Α

Practical Approach

Although universally condemned as dubious and too risky, ηο theoretical refutation of 4 ... tιJc6 ίη the Alekhine is known. It is, moreover, hard to meet ονθΓ the board, as οηθ can easily lose oneself ίη a morass of complications against a well-prepared ορροηθηΙ Ιη the featured game, for instance, Black was happy to 'blitz' his first 17 moves, relying υροη a previous game Lau-Fleck. This Survey disregards 7.tιJg5, 7.1ιd3 and 7.1ιθ3, simply because there are too few theoretical developments worth mentioning. The 'old' main lίηθ is 7.h4 e5 8.d5 tιJd4 9.tιJd4 ed4 10.'t!fd4 e5, and ηονν 11.'t!fd1 promises White a smaII advantage (again there are ηο recent major developments to be reported). This is a slightly unattractive position for Black, so players οη the black side might like to investigate 10... 't!fd7!? instead (see the end of this Survey). Ι ννίll concentrate οη 7.tιJc3.lts basic idea is to get to a slightly favourable version of the lίne just mentioned: 7 ... e5 8.d5tιJd4 9.tιJd4 ed410.'t!fd4, when White has a knight οη c3 instead of a pawn οη h4. The Study Material shows that even here Black need not despair. However, it avoids hair-raising complications, and if a tenable but obviously ';Ι;' position is all Black can get, then why bother playing 4 ... tιJc6 ίη the first place? This explains other replies to 7.tιJc3 Iike 7 ... tιJd7?! and 7 ... g6. The former is not a good idea: both Kuzmin-Pogorelov and Minasian-Sobolewski are virtually winning for Whίte with the middle game barely started. More logical is 7 ... g6, making use of the fact that White has refrained from 7.h4, which he ννίll πονν have to play anyway. After 8.h41ιg7 9.h5!? Kindermann-Fleck, 1983, is still the game to study (Black was busted ίη the more recent examples). Againstthe solid 9.1ιθ3, 9 ... d5 is interesting, following a virtually untested suggestion by Nunn. Also quite playable are 9 ... e5 and 9 ... 0-0, see Lau-Fleck, 1984, and the featured game Bosch-Pajeken, 1997. Black should avoid Kudrin-Behrhorst and the recent Korneev-Diachkov.

SURVEY: A.C.VAN ΟΕΑ ΤΑΚ NOTES: JESUS NOGUEIRAS LUIS SIEIRO GONZALEZ A.C.vAN ΟΕΑ ΤΑΚ

Ruy Lopez Marshall Attack

New games with the Marshall Attack keep οπ pouring ίπ ... The gambit remains popular, especially among correspondence chess players, but such greats as Adams, lνaπ Sokolov, Short and Khalifman have adopted it οπ occasion as well. It could very well be, however, that the times are gradually changing, for ίπ both main games of this survey things did not turn out right for Black. Each time White produced a novelty which got Black into trouble. Ιπ Morovic-Adams White comes υρ with the strong 22.4Jf3! ίπ a position previously assessed by Adams as unclear. Apparently caught by surprise, Black does not find the right solution and ends υρ ίπ a lost position. Only the fact that White slips υρ at move 30 allows the British grandmaster to effect an ingenious escape. Ιπ the postal game Halamus-Zvetkov White refutes an entire lίΠθ! He convincingly demonstrates that a drawing mechanism which has been ίπ the books ΙΟΓ many years does ίπ fact not work. Το all probability 18 ...f5 will have to be replaced by 18... ba4. The Study Material certainly contains enough material for dozens οΙ hours of burning the midnight οίl. The correspondence game Turzynski-Ozimek is very interesting. Ιπ it White tries to improve οπ Popovic-Nikolic, Pula 1984.

SURVEY: DAVID MARCIANO NOTES: DΑνlD MARCIANO

King's Pawn Opening Α

Centre Game Update

IS it really possible to play chess successfully by moving your queen twice ίπ the first four moves, flying ίπ the face of basic principles and yet obtaining a good position? Ι don't believe ίΙ Like Paul van der Sterren ίπ his survey ίπ Yearbook 34, Ι belieνe that the Centre Game is a νθΓΥ dangerous weapon if an opponent is not weII prepared but if Black knows a good defensiνe lίΠθ then the opening can boomerang. The modern 8.'ii'g3 can meet many interesting responses: the obvious 8 ... ttJe4, grabbing the loose pawn, looks good enough though it is very complίcated. After a few hours of analysis Ι have the feelίng that White may already be fighting for a draw. 8 ... J:ιθ4 is probably also good, although with his pieces οπ unusual squares it is more difficultfor Blackto findthe best moves. White, οπ the other hand, only has to find obνious developing and attacking moνes. Ιπ practice this results ίπ White scoring well. Maybe Lane's idea J:ιd4-d6-e6 is the best way to relocate the exposed rook, maintaining a solid position. It is θνθΠ possible to refuse the pawn, but, θνθΠ though the great Karpov himself chose this option, Ι can see πο reason to decline so generous an offer. The old line 8.~c4 has almost disappeared from top lθνθl play ίπ recent years, as the bishop is more a target than an attacking piece, and this gives Black time when mounting his own attack. White has also tried to improve earlier with 5.~d2 but again Black has many good choices such as 5 ... ~b4 (often transposing to the main Iίne after 6.ttJc3 ttJf6) and 5 ... ~θ7, with the choice between a slightly inferior but drawn endgame (Thorhallsson-Nielsen), ΟΓ more complicated positions if fighting for the full ροίπΙ The final alternative, the old 5.e5, is almost obsolete, as Black easily gets the upper hand ίπ the main lίΠθ. Ιπ conclusion Ι believe this opening will soon be out of fashion, as more and more players get to know how to fight against ίΙ

SURVEY: ΡΑυι νΑΝ ΟΕΑ STERREN NOTES: ΑΝΑΤΟΙΥ ΚARPOV

Queen's Gambit Declined Lasker's Defence

Since the Candidates' Match Karpoν-Yusupoν ίπ 1989, Lasker's defence against the Queen's Gambit has enjoyed a moderate but unwaνering popularity. Ιπ that match Karpoν managed to break through Black's solid position ίπ just ΟΠθ game, the final and decisiνe ΟΠθ, and this was the only game ίπ which he played 9.J:ιc1. As a result this has become more ΟΓ less the main lίΠθ, although the more committal 9.cd5, which Ι discussed ίπ Yearbook 40, has also remained important. Ιπ 1989, Yusupoν (after the standard continuation 9.J:l.c1 c6 10.iιd3 tbc3 11.J:ιc3 dc4 12.iιc4 tbd7 13.0-0) chose 13... e5, which was then regarded as the normal moνe. Black lίberates his position ίπ classical style, and it is not at all obνious what White's should do against ίΙ Howeνer, Karpoν showed himself to be well-prepared. He played the flexible 14.iιb3 and demonstrated that White's potential ίπ the open position after 14 ... ed4 15.ed4 was far greater than people thought at the time. This stimulated a search for new ideas for Black, which yielded seνeral interesting methods (mostlyrediscoνeries). Ιπ the first place, answering flexibility with flexibility has proνed useful: the moνes 14... J:l.e8 and 14 ... J:ιd8 stood υρ to practical tests fairly well. Ιπ the second place and more importantly, 13... b6 has become a νθΓΥ popular alternatiνe. Ιπ this way Black immediately solνes the problem of his bishop, at the same time preparing to attack White's centre from the other side with c6-c5, while keeping the option of playing e6-e5 open. This plan has caused White θνθΠ more headaches than the old 13 ... e5, and it was recently adopted by Kramnik and Kasparoν.

SΤAΤISΤICS

Position after 13.0-0

Ιη ουΓ main game it is again Karpov (against Yusupov!) who shows where White's chances lίθ: unhurriedly, he prepares Black's counterplay as well as he can. But however impressive this game, Ι think there is still plenty ΟΙ room lor improvement lor Black. One interesting possibility is 16 ... a5 instead ΟΙ 16 ... ~b7. Flexibility is everything ίη this lίηθ.

MIKHALCHISHIN MIKHALCHISHIN

Queen's Gambit Accepted Απ early~c7

The idea ofthe lines involving an early _c7 is to lure the white queen from the centre ίπ order to ννίπ some tempos later οπ by attacking her. Ιπ the game Malaniuk-Mikhalchishin, Black ended υρ ίπ quite a dangerous situation, but he still managed to equalize. Α good method for White was demonstrated ίπ the game Lukacs-M ikhalchishin, while games by Sermek and Kaidanov present good examples of Black's play. Α hybrid of this system, which arises after 3.e3 c5 4.~c4 cd4 5.ed4 Wic7, is also interesting. This move order does not force White to play 6.Wib3, of course, and it allows him the other possibility 6.~b3 ~g4!? υρ to πονν the battle has brought successes for both sides, which means that the chances are roughly equal. Here the games Matamoros-Sermek and Gelfand-Leko are of great importance. Editorial addition: Besides the obνίous 7.f3, White can also play 7.tίJf3 to meet 6 ... ~g4, which leads to a 'total gambit' after 7 ... ~f3 8.Wif3 Wic1 9.We2. Igor Zaitsev nearly produced a masterpiece with this continuation, with a veritable barrage of piece sacs. Unfortunately he satisfied himself with a repetition of moνes ίπ the final position. Οπ his way home ίπ the Underground he found the forced ννίπ (without using a board!). Zaitsev belieνes that θνθΠ if Black doesn't capture everything and plays 9... Wib2 instead, White has a strong attack, but this is unfortunately not bome out ίπ practice.ln Matamoros-Sermek, White's initiative turned out to be only good enough for perpetual check ... 7.f3 yields White the initiative at the cost of weakening his pawn structure, with all the problems this entails. Here, too, it is difficult to show a clear advantage for White. One thing is certain: whoeνer intends to include this system into his repertoire as Black would be well advised to make a thorough study of the games of Slovenian grandmaster Drazen Sermek!

Catalan Opening

6.iVa4

The idea of the lίηθ 1.d4 tlJf6 2.c4 e6 3.g3 d5 4.~g2 dc4 5.tlJf3 tlJc6 is to save a tempo and play 1:[a8-b8 and b7-b5 without the preliminary a7-a6. Ιη Yearbook 27 Sosonko examined the continuation 6.0-0, which results ίη the sacrifice of white pawns. Here ννθ willlook at 6:ifa4, after which Black has the possibility 6 ... tlJd7 7.'ilνc4 tlJb6 8:ifd3 e5, which yielded him good play ίη the game Wojtkiewicz-Mikhalchishin. White should follow along the lines of Tukmakov-Gelfand. Recent games such as Razuvaev-Dautov (1995/96) and Kachiani-Hunt (1997) confirm the long-standing verdict that Black is struggling for a draw ίη this ending. The second possibility is the very sharp exchange sacrifice which was reintroduced into modern practical play by Kortchnoi ίη Tilburg 1989 against lvanchuk: 6.'ilνa4 ~b4 7.~d2 tlJd5 8.~b4 tlJb4 9.a3 b5! 10.'ilνb5 tlJc2. The latest practical examples, ίη particular the game Chetverik-Grabliauskas, confirmed the conclusion that Black has excellent play. As a result White started to try the pawn sac 9.0-0 ΟΓ the even stronger 8.'i!νb5, which was used by Romanishin ίη his games against Brodsky and Dokhoian. It is this lίηθ that is posing the real problems at the moment.

Nimzo-Indian Defence The Karpov Line

The typical isolated pawn position from the diagram may also arise from the CK Panov lίηθ: 1.e4 c6 2.d4 d5 3.ed5 cd5 4.c4 tίJf6 5.tίJc3 e6 6.tίJf3 ~b4 7.~d3 dc4 8.~c4 ο-ο 9.0-0 b6, etc.ln this survey we will try to compare 11.J:le1 with the more frequently played 11.J:lc1. Please remember there are several transpositions, which causes some headaches forthe opening classification. The idea behind 11.J:lc1 is to take back οη c3 with the rook and ίηνοlνθ it ίη a kingside attack along the third rank. The featured game Acs-Vadasz serves as a good example for this plan. Taking back with the rook is more efficient when Black's knight is οη d7, so after 11 ... i.c3 12.J:lc3, 12 ... tίJc6! is the correct reaction, see Illescas-Short. 12.bc3! tίJbd7 13.J:le1 ! is a more accurate move order, transposing to a lίηθ usually arising via 11.J:le1 i.c312.bc3 tίJbd7 13.J:lc1!, as seen ίη Η. Olafsson-Thorhallsson and Lukacs-Von Herman. 11 ... ~θ7 is also met by 12.J:le1. After 11 ... tίJbd712.'ife2, the idea of 13.J:lfd1 is not dangerous for Blackdue to 12 ... ~c3! 13.bc3 'ifc7!, threatening both 14 ... tίJθ4 and also 14... tίJg4. See G. Giorgadze-Kolev. This leads us to the conclusion that 12.J:le1 ! is better, because nowthe previous plan is harmless: 12 ... ~c313.bc3 Wic714.~d3 tίJg4?! 15.h3!. This is the real difference between 12.'ife2 and 12.J:le1 !. After 12.J:le1 Black can keep the tension with 12 ... J:lc8 13.~d3 J:le8. Now it is not easy for Whίte to make a really useful moνe; 14.Wie2 ~c3 15.bc3 Wic7 gave Black comfortable play ίη Gulko-Short. The aggressive 13.'ifb3 led to a huge advantage for White after 13.. :~θ7?! 14.i.d5!! ίη Browne-Ljubojevic. 13 ... i.e7 does not solve all Black's problems either, see Hazai-Danielsen after 14.~f6! tίJf6? 15.~θ6!. The best defence is probably 13 ... ~c3! 14.J:lc3 (after 14.bc3 the queen οη b3 is not particularly useful) 14 ... h6 15.~h4 ~d5!, steering towards a rather dull endgame with excellent chances for a quick draw, see Lukacs-Macieja. According to the latest theory this is the criticallίne against 11.J:le1 as well.

SΤAΤISΤICS

Position after 10... i.b7 101

After 11.J:ιc1 the most consistent reply is 11 ... tDc6!. Now 12.J:ιe1 is interesting, but not enough for a clear advantage. Although Black lost ίη Speelman-Levitt, this cannot be attributed to the opening. 12.a3 iιe7 13.~d3 leads to Tarrasch opening positions. Here, 13 ... 1:!.c8! is the most flexible reply, preparing for tDd5, e.g. 14.J:ιfd1 tDd5! (Portisch-Karpov), with simplifications leading to equality. 1I White wants to avoid 11.1:!.c1 tDc6! he may begin with 11.J:ιe1. Here 11 ... tDc6 is not quite to-the-point because οΙ 12.a3 iιe7 (12 ... iιc313.bc3, and the ρίη is rather nasty) 13.~d3 J:ιc814.J:ιad1.lt makes a significantdifference between the rook οη d1 instead οΙ c1, see Sarwinski-Przewoznik. 11 ... tDbd7 12.J:ιc1 leads to the positions discussed aboνe. Summarizing ουΓ ορίηίοη, 11.J:ιe1 is perhaps more precise, but 11.1:!.c1 contains venom ίΙ Black wants to take οη c3 early.

SURVEY: ΡΑυL νΑΝ DΕΑ STERREN NOTES: BORIS GELFAND

Nimzo-Indian Defence Ivanchuk's 12... ~ c7!

lη Yearbook 35, Ι wrote a survey οη the popular Nimzo-Indian lίηθ ίη which White plays ~d3 followed by tlJe2 against the classical d5 and c5 by Black. White often plays like this ίη order to avoid the Ηϋbner Variation (4.e3 c5 5.~d3 tlJc6 and if πονν 6.tlJf3, then 6 ... ~c3 7.bc3 d6), so the line has considerable practical importance. Ivanchuk had just introduced the very interesting new moνe 12 ... 'ii'c7 then, and Ι remarked that this idea would undoubtedly arouse great interest. Well, it certainly has.lt was played by Karpov ίπ his FIDE World Championship match against Kamsky and it has superseded all other moves. What is eνen more telling is that ίπ none of these games White was able to come υρ with a convincing reply. Ιπ fact he was mostly found struggling for a draw very soon. Ιπ the recent tournament ίπ Biel, Vadim Μίlον faced this variation twice. He, too, was unable to make any impression whatsoeνer οπ the solid Black position, neither against Gelfand (the main game of this survey) ΠΟΓ ίπ a later round against Karpov. Full marks to Ivanchuk for yet another νeΓY strong opening novelty!

Hungarian Variation

Relatively recently, ίη Yearbook 41, the Hungarian Variation with 7 ... a6 was discussed ίη view of events ίη the Karpov-Kamsky match, which justified the conclusion that Black was not doing well. Black, however, has scored some clear-cut victories during the last few months. Ιη the two most important branches (8.e5 and 8.~e2) clear corrections ίη the assessment ίη Black's favour have had to be made. Piket had undoubtedly prepared an improvement οη his οννη game against Polgar from Lίnares 1997 when he played the Hungarian Variation against Tίmman ίη the 1997 Dutch Championship. Tίmman, however, beat him to it with a spectacular new idea, which he had thoroughly analyzed together with Ivan Sokolov during the MalmQ tournament, which had finished a few days before the start of the Dutch championship. Piket obviously did not need to lose this game, but he used υρ oceans of time during the opening and eventually caved ίη under the pressure. 8.~e2 has a reputation of being solid. The first moves of my game against Svidler ίη St. Petersburg 1997 were played quίte fast, as υρ to and including move 18 we were repeating the game Piket-Ivanchuk, Monaco 1995. Although White lost this game, Ι believe his play can be improved υροη. 20.J:ιa3 (instead of 20.a3) would have guaranteed White a plus. It must be said that the white c5 pawn plays a central part ίη this position, which is rather difficult to handle for both White and Black. Black doesn't have time to ννίη back this pawn, which has arrived there after the breaking move c7-c5, which is typical of the Grϋnfeld. Το hang οη to this trump card - isn't it, after all, a well protected passed pawn? - White is prepared to give υρ his central e-pawn, and if necessary even his queenside pawns. ΜΥ opponent uncorked a strong novelty at move 19, leading to advantage ίη the ensuing dynamic middle game, although afterwards he immediately showed me an improvement for White. According to the latest information, the ball ίη this variation of the Grϋnfeld is firmly back ίη White's court.

King's Indian Defence Classical Variation

Say 'Rook e1' to any King's Indian player and he will immediately know what you mean. The moνe 10.]:[e1 ίπ the 9.b4 lίΠθ of the Classical Variation has come, been seen and conquered. Not only those habitually ίπ the fast lane who always pick υρ any new idea howeνer good ΟΓ bad, but θνeπ players less trendy ίπ their opening policy haνe come to the conclusion that 10.J:l.e1, introduced by lνaπ Sokoloν ίπ 1995, is simply a good moνe that cannot be ignored. Speaking for myself, Ι haνe θνθΠ found this brand-new νariation a kind of eye-opener. Most of the νariations ίπ this, the most classical and yet the sharpest of all King's Indian lines, always seemed to me to somehow fall outside the laws that goνern 'normal' openings. Νο matter if you played 9.ttJe1, 9.ttJd2, 9.b4 ΟΓ whateνer, Black always seemed to get a kingside attack and it always seemed uncannily easy for White to lose control and get blasted off the board. Απ awful lot of 10.1:[e1 games that Ι haνe studied, show a completely different picture: normal positional play, attempts by Black to get the initiatiνe successfully thwarted, understandable positions. And the results haνe been amazingly good. Theoretically, it is unlikely that any moνe, 10.1:[e1 ΟΓ otherwise, could refute the King's Indian ΟΓ θνeπ seriously threaten it, but psychologically it has changed at least my νiew of the Classical King's Indian. It has been brought back to earth. Απ eχcellent oνerνiew of theactual νariations was giνen by Viktor Gaνrikoν ίπ N/C Magazine 97/4. This surνey contains some games that were played since, and the main game is an especially memorable ΟΠθ: Kramnik (who has been νθΓΥ quick to make 10.1:[e1 a magnificent weapon ίπ his opening arsenal) beats Kasparoν ίπ the popular and relatiνely solid lίΠθ 10 ... ttJf4 11.~f1 a5 12.ba5.

King's Indian Defence Benjamin Variation

Some years ago, the American grandmaster Benjamin introduced the move 7 .. :iWb6 ίπ the ΙίΠθ 1.d4l2Jf6 2.c4 g6 3.g3 it.g7 4.~g2 ο-ο 5.l2Jf3 d6 6.0-0 c6 7.l2Jc3 instead of KaνaIek's approved 7 ... 'iWa5. For a coupIe of years he was the ΟΠΙΥ ΟΠθ to use this idea successfuIIy, but Iast year it aroused the interest of VasiIy Ivanchuk and his trainer. The first time Ivanchuk pIayed this way ίπ an officiaI game was against Karpov ίπ Las PaImas 1996. Karpov's reaction was somewhat panicky - 8.c5?! - aIthough this continuation ννίΙΙ doubtIessIy be seen ίπ practicaI pIay more often. 8.b3 is stronger and occurred ίπ the game MikhaIchishin-Buturin, Ινίν 1996, where BIack pIayed excessiveIy passiνeIy. The game Razuvaev-Filippov, Novgorod 1995 cannot serve as a modeI game for BIack either.

NIC SURVEY

816.3

SURVEY: LlAFBERN RIEMERSMA NOTES: LlAFBERN RIEMERSMA

Benoni Defence The Half Samisch

Ιπ his extensive theoretical article ίπ NIC Yearbook 39 Albert Kapengut dealt with the main body of theory of a most popular lίΠθ of the Βθποπί, often arising from the ~g5 Samisch. As a supplement to his work, this survey wiII feature the sidelίne with 9 ... ~d7. With this move Black avoids most of the mainstream theory, and aims for b7-b5 only. Unlike the main Iίnes, White's possibilities are quite restricted. The g1-knight should always go to e2 and subsequently to g3. Only the position of the Iίght-squared bishop is Ιο some extent flexible; apart from that White's main concern is finding an appropriate move order. After 9 ...~d7 White's options are 10.a4, 10.~c4 followed by a2-a4, 10.~d3 and 10.llJge2. The awkward-Iooking 10.~d3, employed by Lautier ίπ an exhibition match against Piket, is interesting, but gives Black a lο! of play οπ the queenside and has not found many adherents. Οπ a few occasions 10.llJge2 has been played, but it allows an immediate b7-b5 and White has υρ to now been unable to take advantage of this early queenside thrust. This leaνes us with 10.a4 and 10.~c4 which usually willlead to the same positions, though the latter might be slightly more accurate. The deployment of the bishop to c4 is logical, as for the time being πο black knight will reach e5. Also it is often convenient to ρυ! υρ a blockade οπ c4. If Black does πο! ορ! for Νenasheν's 11 ... llJc7 (see Ker-Nenashev among the study material), which is νθΓΥ passive, either of two key positions wiII arise: the position after 13.0-0 (Riemersma-Krakops) ίπ which Black prevents a4-a5 by playing b7-b6, ΟΓ the position where Black plays J:ra8-b8 instead of b7-b6 ίπ Behrhorst-Horstman (via a different move order). Ιπ the former lίΠθ White must put υρ with b6-b5, but has dangerous play ίπ centre. Ιπ my game against Krakops Ι was probably a bit too aggressive and far too careless. But the main idea must be correct - as Black has neglected his control of f6 and e5, the standard attack with ~xf6 followed by e5 and f5 seems crucial.

SΤAΤISΤICS

Position after 9 ... ~d7 142

Survey ΒΙ 6.3 Ιπ the latter lίΠθ White keeps control ο! the queenside, but Black can free his pieces with ~d7-b5 and tLJf6-d7. White is ίπ πο hurry ίπ this line. Still he has the opportunity to break through ίπ the centre immediately, but this is probably premature (see the analysis to Behrhorst-Horstmann). White seems to be better ίπ both lines, as the black knight is awkwardly placed οπ b4. The white player, however, should remain careful throughout the game. ΙΙ he makes ΟΠθ mistake, he might be crushed ίπ similar fashion as for example lonescu against Wahls (after an untimely a4-a5).

The Modern Main

Ιίnθ

The article from Yearbook 28 by one of these authors was devoted to a topical system against the Modern Benoni which has two important features. ιι has superseded all other systems ίπ tournament practice and many games with this system arise from various systems of the King's Indian Defence. One of the main conclusions of that article was the recommendation for Black after 10.tLJb5 ιο avoid A.Chernin's idea of 12.tLJg5!, used for the first time by L.Alburt against N.de Firmian ίπ 1990. This lίne can be bypassed by substituting 10 ... tLJe4 with 10 ... J:ιe8, played for the first time ίπ a 1989 game between S.Kalinichev and A.Semeniuk. Over the last few years this has indeed become the main line - ουΓ database at present holds well over 100 games ίπ the period 1993-97 alone. Ιπ the overwhelming majority of cases White continues 11.0-0 tLJe412.J:ιe1. However, the survey game is devoted to an interesting new idea (12.1Ifa4), which wasdismissed as unpromising ίπ Yearbook28. The future maycertainly modify ΟΓ refute the conclusions of the auIhors, buI for Ihe time being we haνe 10 say Ihal Black has some serious problems 10 solνe.

NIC THEORV

QG 8.3

The subject of our inνestigatίons is the so-called Furman Vaήatίon of the Queen's Gambit Accepted. Characteήstίc of this line is the continuation 1. d4 d5 2. c4 dc4 3. ltJf3 ltJf6 4. e3 e6 5. ..tc4 c5 6. 'iνθ2 a6 Positions with an isolated pawn after 6 ...cd4 7.ed4 will nοΙ be considered ίn this article. 7. dc5 ..tc5

This νaήatίon takes its name from the well-known Russian theoretician and grandmaster Semen Furman, who played numerous games with ίι ίn the 1950s and 1960s. During the eightίes Furman had few comrades-in-arms, but the popυlaήΙy of the νaήation rapidly increased when ίι was adopted by renowned players like Portίsch, 188

ΑLΕΧΑΝDΕΑ RAETSΚY

Queen's Gambit Accepted The Furman Variation Tιmman,

Kortchnoi, Gelfand, and later Anand and Topa1oν. The most important cοntήbutίοns to the deνelopment of the νaήatίon were made by grandmasters Ι. Sokoloν, Yakoνich and Ma1aniuk. The main idea of the Furman νaή­ ation is that White, haνing aνoided the queen swap, prepares the centra1 adνance e3-e4-e5, followed by a kingside attack. Black for his part tήes Ιο preνent this by taking control of square e5 with his pieces. The ensuing positίons are quite complicated and interesting. Ιn practίca1 play White often refrains from the adνance e3-e4, but immediately fianchettoes his darksquared bishop, resultίng ίn a quiet, rather boήng game. The author had considerable problems classifying the mateήaΙ due Ιο the numerous possible transpositίons, which is why the diνision ίnΙο chapters, νaήations and sub-νaή­ ations is Ιο a certain extent arbitrary. Ιn the diagrammed positίon White may choose Ιο delay castling; ίι is examined ίn Chapter Ι (8.a3) and Chapter Π (8.e4). The main continuation, 8.0-0, makes υρ Chapter ΙΠ. Chapter Ι 8.a3 Chapter Π 8.e4 Chapter ΙΠ 8.0-0

Chapter Ι 8. a3 This is less flexible than 8.0-0, so ίι occurs quite rarely. 8. ... b5 The moνe 8 ...
