ASEAN Masters Chess Circuit 2008 (5), 12.01.2008

1.e4 Nf6 Susanto choose the Alekhine Defense 2.e5 Nd5 3.d4 d6 4.c4 Nb6 5.exd6 Wesley play the Exchange variation. White trades pawns, accepting a more modest spatial advantage. Black's main decision is whether to recapture with the solid 5...exd6 or the more ambitious 5...cxd6. 5...exd6 6.Nc3 Be7 7.Bd3 Nc6 8.Nge2 Bg4 9.Be3 Qd7 10.0–0 Nb4 11.b3 Nxd3 12.Qxd3 d5 13.c5 Nc8 14.Ng3 although black have the bishop pair, his piece seems uncoordinated. 14...Bh4?! i think black should complete his development with 14...0-0 15.f3! Wesley sense that Susanto have probably overlooked this possibility 15...Bxg3? White have a tactical combination with 16.fxg4 Bh4 17.g5! Wesley is threatening to trap the bishop with 18.g3! 17...h6 18.gxh6 gxh6 19.g3 Be7 20.Rae1 black king side position is totally wrecked!15... Be6 16.Nh5 0–0 17.Qd2 Bd8 now it's clear that black 14...Bh4 is just wasting a tempo 18.Rae1 f6 19.Re2 Bf7 20.Nf4 Ne7 21.Rfe1 Nc6 22.Bf2 Be7 23.b4 a6 24.a4 Rfe8 25.b5 axb5 25...Nb4 26.Ne6 26.axb5 Na5? This move cause black a pawn and leads into a difficult endgame 26...Na7 although passive should be played

27.Ncxd5!± Wesley didn’t missed his chance! 27...Bxd5 28.Nxd5 Qxd5 29.Rxe7 Rxe7 30.Rxe7 Nb3 31.Qc3 Ra1+ 32.Re1 Rxe1+ 33.Qxe1 black can't get back his pawn with 33...Nxd4?? cause 34.Qe8++mate 33..Kf7 34.Qc3 Ke6 35.h4 h5 36.Be3 Kd7 37.Qc2 white plan to exploit black weak king side pawn with 38.Qg6 so Susanto prevent it with 37...f5 37...Nxd4? would be a mistake after 38.Qd1 Nxf3+ 39.Qxf3 Qxf3 40.gxf3+- 38.Qc3 38.b6! is better because after 38... cxb6 ( 38...c6 39.Qa2 Qe6 40.Bf2 Qf7 41.Qa8 the b7 pawn will drop!;) 39.cxb6+- black will have too many problem especially the b3 knight and weak c7 square 38...g6 39.Bf2 Qe6?? shortens the misery for Black 39...c6 40.b6+- 40.Bg3 40.c6+ and White wins after 40...bxc6 41.bxc6+ Kc8 42.Qb4 Qxc6 43.Qxb3+- 40...Qd5 41.Be5 c6 41...Ke6 42.Qe3 Kd7 43.Kh2+- 42.bxc6+ Kxc6 43.Qb4 Nc1?

44.Qb6+? probably both player was in time trouble because white can simply win the queen with 44.Qa4+ b5 45.Qa8+ Kd7 46.Qxd5+ 44...Kd7+- 45.Qxg6 1–0
