GM Wesley So(2627) - GM Frank Holzke (2524) [C78]
Corus C Wijk aan Zee NED Round 8, 25.01.2009


1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0–0 Bc5 6.Nxe5 Nxe5 7.d4 Nxe4 8.Re1 Be7 9.dxe5 Nc5 10.Nc3 0–0 11.Bf4 Nxa4 12.Nxa4 d5 13.exd6 Bxd6 14.Bxd6 cxd6 15.Qd4 b5 16.Nb6 Rb8 17.Nd5 Re8 18.Rxe8+ Qxe8 19.Ne3 Qd8 20.Rd1 Rb7 21.Rd3 Rd7 22.h4 Qf8 23.h5 h6 24.c4 Rc7 25.Qb6 bxc4 26.Rxd6 Qe7 27.Rc6 Rxc6 28.Qxc6 Be6 29.Qxa6 Qb4 30.Qa8+ Kh7 31.Qe4+ Kg8 32.Qc2 Qe1+ 33.Kh2 Qa5 In diagram below, Wesley is a pawn up and his pawn majority on the queenside should gave him a big advantage . Move like 34.a4 giving back the pawn for tempo is correct for e.g 34...Qxh5+ 35.Kg1 Qa5 (35...Qe5 36.Qc3 Qxc3 37.bxc3 Kf8 38.a5 Bc8 39.Nxc4) and only now 36.Nxc4 Qc5 37.b3

34.Nxc4?? a terrible blunder. Probably Wesley missed black's next move 34... Qc7+ Now black will win a piece after 35.Kg1 Qxc4 36.Qxc4 Bxc4 37.b3 Bd5 38.f3 Kf8 39.Kf2 Ke7 40.Ke3 Kd6 41.g4 f5 42.Kf4 Ke6 0–1
