Botvinnik Semi-Slav, The (Pedersen)
164 THE BOTVINNIK SEMI-SLAV thus it avoids Black winning it with a ... b4 followed by ... lDxe4 sequence, but since this is often too risky for Black, I prefer 9 J.e2. Nevertheless, it is not unusual in the main lines for White to adopt a set-up with the queen on c2 and while I could have gathered all the 'iVc2 set-ups together here, I have decided rather to cover them in later branches where appropriate. Here, though, are three independent attempts for Black that do not fit in elsewhere: cl) 9 ... g4 (with this Black goes for another pawn but it looks too risky) 10 lDeS 'iVxd4 11 ':'dl 'ii'b6?! 12 J.e2 hS?! 13 lDg6! (an instructive motif; White deflects the pawn from f7 and thus ruins the cover of Black's king with the aim of following up with eS, opening an entrance for the queen) 13 ... fxg6 14 eS ~f7 (Black cannot allow White's queen to capture on g6 with check) IS exf6 eS 16lDe4 J.b4+ 17 ~f1':'eS IS a3 J.fS 19 ':'d6! with a winning attack, Gabriel-Zhu Chen, Bad Homburg 1995. c2) 9 ... b4!? 10 lDa4 b3 11 'iVxc4 lDxe4 12lDc3 lDxg3 13 hxg3 bxa2 14 ':'xa2 as! with an unclear position, Bellon-Bator, Stockholm 1999. c3) 9 ... J.g7!? 100-0-00-0 11 eS (it is a bit unusual for White to castle queenside in the Anti-Moscow Variation, and following up with eS looks inconsistent; I would prefer 11 h4 g4 12 lDeS) 11...lDdS 12 lDe4 (White's play seems a little primitive and in the following it is obvious that the white king is the more exposed) 12 .. :ii'aS (threatening ... lDb4!) 13 a3 b414 J.xc4 bxa3 IS bxa3 J.a6 16 ':'d3 J.xc4 17 'ii'xc4lDd7 IslDfd2 cS 19lDxcs ':'fcS 20 lDde4 J.f8, Yurtaev-Shirov, Elista OL 1995. White's attack never really got going and hence Black already has a winning position. Now we return to 9 J.e2 (D): B We shall now consider four main options for Black: A: 9 ... b4?! 164 B: 9 ... J.b4!? 167 C: 9 ... J.b7 169 D: 9 ... lDbd7!? 177 9 ... lDhS had a successful outing in Oll-Liiva, Estonian Cht (Tallinn) 1995 but is not worth repeating. After 10 J.eS ':'gS 11 J.xbS ':'xbS 12lDe5 lDf4 13 lDxc6 'ii'b6 14 lDxbS lDxg2+ IS ~f1 lDf4 White could now have got a winning position with 16 J.xc4!. A) 9 ... b4?!
THE ANTI-MoSCOW VARIATION: 6 ~h4!? 165 This is an extremely ambitious attempt but in view of Sakaev's fantastic 12 lLlcS!, it can now more or less be written off. Since White's knight has to move, Black will gain the e4-pawn, and, he hopes, will be able to exchange off White's dark-squared bishop. But as we shall see, White will be able to keep this bishop alive and, just as importantly, obtain a dangerous initiative. 10 lLla4 This is definitely best. Even though it is not strictly necessary, White is advised to move the knight and from a4 it keeps on eye on the cS-square. Others: a) 10 eS? bxc3 11 exf6 cxb2 12 %:tb1 'iWaS+ 13 cJi>f1 c3 +- Pecorelli Garcia-Nogueiras, Villa Clara 1998. b) 10 tiJb1 tiJxe4 11 0-0 i..g7 12 i..eS tiJf6 13 tiJbd2 c3 14 bxc3 bxc3 IS tiJc4 0-0 16 i..d6 lIe8 17 tiJfeS i..a6!? 18 i..xb8 i..xc4 19 i..xc4 l:txb8 + Karason-Thorsteinsson, Icelandic Ch (Akureyri) 1997. 10 ..• tiJxe4 11 .teS! Unfortunately White does not have to cooperate! l1...f6? is now too loosening in view of 12 'iWc2!, so by moving the bishop and simultaneously attacking the rook, White gets time to deal with the e4-knight. An alternative is 11 i..xc4 but as has been shown, Black's life is a lot easier without White's dark-squared bishop. After 11...lLlxg3 12 hxg3 (Timman's suggestion of instead opening the f-file by 12 fxg3!? remains untested) 12 ... tiJd7 13 0-0 i..g7 14 %:tel 0-0 White seems to have fairly decent compensation. Black's pawn-structure is the usual mess but he still has one pawn more, and White needs a real target. The c pawn is the most obvious, and there are two ways to begin the pressure against it: a) IS l:tc1 is the most logical but, as pointed out by Timman, this allows Black to equalize with lS ... tiJb6!? 16 i..b3 tiJxa4 17 i..xa4 i..b7 18 i..xc6 i..xc6 19 %:txc6 'iWdS 20 'iWa4 l:tfd8, rather than IS ... i..b7 16 i..d3 cS (this does not look very convincing, but Black needs to free his position somehow) 17 dxcS i..c6 18 i..e4 'iWc7 19 i..xc6 'iWxc6 20 %:te2!, when Black was struggling because of White's strong passed pawn and good control of the centre in Korchnoi-Timman, Wijk aan Zee 1997. b) IS .td3!? anticipates the ... tiJb6 idea and was suggested by Timman afterwards, with the intention of meeting lS ... tiJb6 with 16 tiJcS. 11 ... tiJf6 (D) If this is the big idea of the 9 ... b4?! line, I am not surprised that White is able to find a refutation. The logic behind it is less than impressive. Black exchanges his c-pawn for White's e pawn but also wrecks his own pawnstructure even more. However, 11.. .:g8 has no bright future either: a) 12 i..xc4 g4 13 tiJd2 tiJxd2 14 'iWxd2 lLld7 IS i..f4 'iWaS 16 lLlcs tiJxcs 17 dxcS i..xcs 18 :dl i..e7 190-0 ± Ligterink-Kuijf, Dutch Ch (Hilversum) 1986.
