160 THE BOTVINNIK SEMI-SLAV B line 'b', while the game Lammi­ Dokhoian, Helsinki 1992 provided the entertaining continuation 8 'iWc2 b5 9 .Jtxf6 (if 9 e4 g5 10 .Jtg3 Black can play safe with 1O ... .Jtb7 or even try the riskier 10 ... g4!?) 9 ... 'it'xf6!? 10 axb5 cxb5 11 'it'e4 'it'f5! 12 'it'xa8 'it'c2 13 lDd2 'it'xb2 14 .l:.dl.Jtxc3 15 e3 .Jtxd2+ 16 .l:.xd2 'iWal + 17 ~e2 0-0 18 'iWxb8 c3 19 .l:.c2 .Jta6 and Black was winning. b) 7 e3 b5 8 a4.Jtb4 is most likely better for Black, but it is worth noting that it is the kind of position that usually provides White with quite reasonable practical chances. Sometimes it is even easier for White to make use of his extra centre pawn than it is for Black to get something out of his rather shaky pawn majority on the queenside. The following are the most common options in practice: bl) 9 axb5 cxb5 10 tDd2 'it'b6?! (10 ... .Jtxc3 11 bxc3 .Jtb7 transposes right into 'b43' below) 11 .Jtxf6 gxf6 12 'it'f3 .Jtb7 13 'it'xf6 .l:.h7 14 .Jte2 tDd7 15 'it'h4 .Jte7 16 'iWh5 .Jtxg217 .l:.gl .Jtc6 18 .Jtf3 and White has very good compensation as Black has great difficulties finding a safe place for his king, Lesiege-Fridman, Bermuda 1998. b2) 9 'it'c2 .Jtb7 10 tDd2 a6 11 .Jte2 tDbd7 120-0 'iWb613 tDf3 0-014 :fdl nfc8 + Pajeken-Steckner, Hamburg 1992. b3) 9 tDe5 'it'aS 10 'iWeI 'iWb6 11 i.e2 i.b7 12 0-0 tDbd7 13 f4 a6 14 .Jtf3 0-0 15 tDe4 'it'c7 16 tDxf6+ tDxf6 17 'iWc2 tDd5 18 .Jtxd5 exd5 19 f5 f6 20 tDg6 nfe8 gives Black a clear advantage, Hillarp Persson-A.Matthiesen, Copenhagen 1996. b4) 9 tDd2 is the most common . White unpins the c3-knight while also toying with ideas of exchanging on b5 followed 'it'f3. The hope is that Black may feel obliged to concede his darksquared bishop quickly in order to prevent this. Now we have: b41) 9 ... a61O axb5 .Jtxc3 (1O ... cxb5 is preferable, with an unclear position after 11 tDxb5 axb5 12 nxa8 .Jtb7, but the real idea is that 11 'iWf3? :a7 12 'it'g3 fails in view of 12 ... g5 13 'it'xb8 l:lb7 14 'iWe5? .Jtd6 -+) 11 bxc3 cxb5 12 'iWf3 'it'd5 13 e4 'iWh5, Bronstein­ Pachman, Moscow 1967, and now 14 'iWg3! tDbd7 15 .Jte2 'it'g6 16 'iWd6! 'it'xg2 17 .Jtf3 'ii'h3 18 e5 is clearly better for White. b42) 9 ... .Jtxc3 10 bxc3 tDbd7 11 axb5 cxb5 12 'iWf3 is good for White since either the rook must move, which permits l:ha7, or Black has to play 12 ... tDb6, when 13 tDe4 illustrates the danger of Black conceding the dark-squared bishop.
