After having exa m ined all the main positions i n detail, the following chapters will now show you how to get there !

Black could just about manage to parry the attack but he wil still have a disadvantage in the endgame. Conclusion: The type of posi t ions after 7 . . .0-0 are exactly what the normal London System player wishes for. 7 ... �xe5, on the other hand, is an interesting attempt for equality, as Black avoids castling kingside for the time being and thereby does not give White a target for an attack. lt is very

Very unusual at this stage, but in contrast to some other positions, White cannot avoid the bishop exchange by tactical means. A retreat to d2 or e3 is out of question and the petty 4.�c1 - in the hope of 4 ...lt:\f6 with a repetition of moves - is firstly embarrassing and secondly Black can continue with 4 ... f5 Very bad on the other hand is: [3...�g4? White can win a tempo with 4.tt:'le5, which is already sufficient refutation. �h5 (4 ...�f5 5.tt:'ld2 tt:'lbd7 6.e3 e6 7.g4 �e4 8.f3 �g6 9.h4 h6

Allowing the exchange. [5.�d2!? I personally consider this to be a clever choice. White waited until Black played ... h6 and only now retreats his bishop to d2. The idea of .. .f5 is not recommendable because of the weakness of the square g6 and the fact that bringing the tt:'lh5 back into the game will also cost some more time. Unfortunately White can forget about getting into a position of the London System, but the game will be a long way off any theoretical variations ... !] 5 ... g5

3 ... tLlh5!? [5 ... tt:lc6 is inconsequent because although White cannot avoid the exchange of his bishop after 6.e3 g5 7.tt:lfd2 he is able to win some valuable time: 7 ... tt:lg7 8.ii.g3 tt:lf5 9.c4 with a certain advantage.] Chapter 9 -

6.ii.g3 tt:lxg3 7.hxg3 ii.g7 (064)

Protects the rook and thus prevents 4lxg5. lt is not easy to give a defin ite evaluation of the position. Black's kingside has been weakened, but this has secured him the pair of bishops. On the other hand, the :gh1 was developed for free. Therefore, castling short would be extremely risky for the black monarch. The chances for White can be regarded as slightly better. More important than anything else is to know how to deal with this position.

[7 ... ii.f5? 8.e3? ii.g7 9.ctJbd2 tLlc6 1 O.c3 \Wd6 1 1 .\Wb3 0-0-0= is equal, as pointed out by Kovacevic (Salamon-Kelly,Budapest 2003), which is certainly correct. However, 1 would just take the pawn with 8.ctJxg5 on the 81h move, and although Black will get some compensation, it should not be sufficient.] 8.e3 c5 9.c3 (065)

Opening up the position with 9.c4 is not exactly what White wants, as the il,g7 would become too strong. This is the critical position after 3 ... ctJh5. Black has many moves to choose from and it is still not clear which is the best. 65

My recommendation! strongly believe that the following alternative is not quite as strong as the text move: [1 O.dxc5 Opening up the position with the �g7 still being on the board looks double-edged, but White may well allow himself the luxury of playing like this. 10 ... 0-0 1 1 .tt:'lbd2 (1 1 .1Wc2 The only game with 10.dxc5, but I must admit that I do not quite understand the following moves. 1 1 ... e5 12.tt:'la3 '.We? 1 3.tt'lb5 d4 14.tt:'ld6 dxe3 1 5.0-00 (15. fxe3+- is easy and good.) 15 ...�e6 16.fxe3 f5 1 7.g4 fxg4+­ Masek-Trefny Czech Republic, 1993.) 1 1 ... e5 12."1Wb3 followed by castling queenside looks very promising.]

Similarly to Chapter 2 (with 2 ... e6 and 3 ... .id6), Black strives for a quick exchange of bishops. He is not worried about voluntarily trading off his good bis hop (Black's central pawns are mainly standing on light squares!) for White's bad one. The fight for control over e5 is more important to Bla ck. There are two serious possibi lities for White, 5 ..ig3 (wh ich will be analysed i n the next chapter) and the text move: 5.tLle5

[5 ... c5? is already bad. 6 ..ib5+ and the king must move because on 6 ... 4Jbd7 (6... '\tJel!?-;) a smashing strike would follow: 7.4Jxf7! xf7 8 . .ixd6 Wb6 9 ..ixd7 Wxd6 (9. . .

[6 ... t/Jbd7?! Black can probably continue adopting his Queen's Gambit set-up without having to pay attention to the white piece placement. But it is important to notice that the knight blocks the queen's view onto the bishop. 7.id3 Black cannot afford to (6 ... b6 7.id3 White keeps his c-pawn move· the c-pawn as his id6 would on its initial square, ready to counter no longer be protected and t/Jxf7 ia6 with c4 - if necessary. would be possible. 7 ..

After having avoided a few small pitfalls, Black can really be satisfied with himself. In contrast to the position in Chapter 1 , the ctJf3 has moved to e5 without awaiting the threat of ... e6e5.

Even though a lot of good playe �s . chose .id3, I believe the b1shop IS better off on e2, where it stands very safely - particularly after Black has advanced his pawn to eS. 237

The Gruenfeld set-up can arise after 1 �:;:_;:=..:;:;�..::r-����"h either 1 . . . d5 or also after 1 . . . Sf6. We will examine the positions where Black starts with the double step of his d-pawn, after wh ich the centre ha s . been fixed to a certain extend. Black,s most important idea consists of . . . tt'lfd7/. . . e 5 - a plan which i s d ifficult to H aving two attractive squares for t� e prevent. If Black pursues a completely bishop is the main reason why Wh ite . d ifferent approach without p repanng usually starts with tt'l bd2! the breakthrough . . . eS, White normally gets a pleasant game as Black's 5 ... 0-0 . bishops are difficult to act1vate.

I n general it is risky for Black to attack the bishop with . . . tt:lh5 after having played . . . c5, as White may take on c5 and it will be extremely d ifficult for him to get the c5-pawn back.
