Foxwoods Preston CT (2), 10.04.2009

1.d4 e6 2.c4 d5 3.Nc3 Nf6 4.Nf3 Be7 5.Bg5 Even though Black has already played ...Be7, White intends 6.e3 and wants to get his dark bishop outside the pawn chain. 5...0–0 6.e3 White prepares to develop his light bishop. 6...c6 [6...h6 is stronger.] 7.Bd3 Prepare to castle.

 7...c5 8.Bxf6 White wanted to give Black an isolani without the possiblity of Black's knight recapturing. [Fritz suggests 8.cxd5 cxd4 9.Nxd4 exd5 which gives Black an isolani, but 8...Nxd5 is possible.] 8...Bxf6 9.cxd5 cxd4 10.Nxd4 exd5 Black has two bishops, and an isolani. It's up to White to prove that the isolani is more of a liability than the benefit of two bishops.

11.0–0 White is playing tough but conservative. As a result he missed a simple combination to pick up a pawn. [Perhaps 11.Qh5 could be considered for the power of double attack (mate and double attack on d5). 11...g6 only 12.Qxd5] 11...Nc6 White has a choice, retreat the d4 knight (say to f3), and risk creating an isolani, or exchange knights, and help Black create hanging pawns. In the judgement of White, creating the hanging pawns was the more profitable choice because he is confident that he can keep them from advancing, which means that they then become a target and a liability. In fact, immediately after the bxc recapture, the c-pawn is backward, and White thinks he can put pressure on it quickly. Black won't be able to immediately advance to c5 because of the Bxh7+ tactic. 12.Nxc6 bxc6 13.Rc1 White starts to apply pressure on the c6 pawn.

13...c5? Black wants to get his hanging pawns moving, but this fails to tactics. 14.Nxd5 Black cannot recapture. Black also has an isolani again. White is attacking c5, while Black is attacking b2. 14...Bxb2 Black wants to trade off his isolani. However, with White's Rxc5 recapture, this attacks the c7 square twice. 15.Rxc5 Be6 16.Nc7 White feels he has an advantage. 16...Qd6?? Black is double attacking White's rook and knight, trying to force them back. [16...Rc8 Doesn't work 17.Nxe6 Rxc5?? (17...fxe6 18.Rxc8 Qxc8 19.Qc2) 18.Nxc5; 16...Rb8 A little better 17.Nxe6 fxe6 but still results in an isolani. 18.Rb5] 17.Bxh7+ White didn't see this tactic twice in one game (also on Black's 13th move).

17...Kxh7 18.Qxd6 Rad8 19.Rh5+ Black still has two bishops, so White still has to be very careful, and keep Black on the run. 19...Kg6 [19...Kg8 Holds out longer.] 20.Qc5 Threatens 21.Qg5#.

20...Bf6 only. 21.Nxe6 [White missed 21.Qc2+ Kxh5 22.Qh7+ Kg5 (22...Kg4 23.f3+ Kg5 24.h4#) 23.f4+ Kg4 24.Qh3#] 21...fxe6 22.Rh3 White prepares mate, expecting Black's king to run to f7. 22...Rf7 Oops. 23.Qh5# 1–0
