Can open, 2001
1.c4 Nf6 2.Nc3 d5 3.cxd5 Nxd5 4.Nf3 c5 5.d4 cxd4 This line is difficult to play, and therefore must not be recommended against a better player. Statistically black scores something like 15 or 20 percent in this line. Is that good? 6.Qxd4 Nxc3 7.Qxc3 Nc6 8.e4 e6 9.Bb5 Bd7 10.0-0 Qb6 Inspite of the apparent symmetry in the pawn structure, black has difficulties completing his development. White just has to make simple moves like Rd1 and Bf4 to cause black to ache... 11.a4 Qc5 A common manoevre in this line. 12.Qd3!? This move is more common in practice. [12.Qe1!? a6 13.Be3 Qb4 14.Bd2 Qd6 15.Be2 Be7 16.Rd1 Qc7 17.b4! 0-0 18.b5 axb5 19.axb5 Nb8 20.Bc3 f6 21.Rc1 Qd8 22.Bc4 Qe8 23.Qe2 and white was clearly on top, as in the recent Tukmakov-Suetin, 2000, 1-0 in 35 moves] 12...Qd6 13.Qe2 Qc7 [13...Be7!? this is more usual in practice, and in as much as it helps to develop should take preference over the game move] 14.a5!? Be7 [14...Nxa5? 15.Bxd7+ Kxd7 16.Qd2+ oops!; 14...a6!] 15.Rd1 0-0 [15...a6!] 16.Bf4! Qc8 [16...Qxf4 17.Rxd7 Bf6 18.a6 is hard to meet] 17.a6 Black is busted 17...e5 As good as any, I suppose. Black overlooked what now happens, but at least he avoids suffering much 18.axb7 Qxb7 19.Rxd7! Qxd7 20.Nxe5 Nxe5 Well, why not!?! 21.Bxd7 Nxd7 22.h4 The rest is technique. Somewhat surprisingly, black finds a way to resign with a clear conscious... 22...Rfc8 [22...Bxh4 23.Qg4] 23.h5 h6 24.Bxh6 Enough! I am sure that Black got up on the wrong side of the bed this day. 1-0
