1.d4 d5 2.Nf3 Nf6 3.Bg5 h6 This move gains the two bishops but weakens blacks pawns and can lead to a passive defence. [A more active defence is 3...Ne4 4.Bh4 c5 5.dxc5 (Or 5.e3 Qb6 6.Qc1 Nc6 7.c3 Bf5 ; 5.c3 Qb6 6.Qb3 Nc6 7.Qxb6 axb6 8.e3 c4 ) 5...Nc6 6.e3 g6 7.Nbd2 Nxc5 8.Nb3 Bg7 9.c3 ( 9.Nxc5 Qa5+ regains the knight.) 9...Ne4 as in Timman-Shirov Corus 2001- which black won]
4.Bxf6 exf6 5.e3 Bd6 6.c4 dxc4 7.Bxc4 Be6?! swaps bishops but gives white an advantage after his next move. [An alternative setup is 7...0-0 8.0-0 Nd7 9.Nc3 Nb6 10.Bb3 c6 ]
8.Bxe6 fxe6 9.Qb3 Qc8 10.0-0 a5 aiming to bring the black rook into play via a6 or a5 after ..a4
11.d5 Nd7 12.Nc3 Nc5 13.Qc4 e5 14.Ne4 Here white chooses the wrong plan allowing black to free his game. [A better idea is 14.e4 0-0 15.Nh4 trying to play on the weak squares around blacks kingside.]
14...Nxe4 15.Qxe4 f5 16.Qh4 0-0 Now black is at least equal.
17.Rfe1 [Playing on the queenside is another idea - 17.Qc4 a4 18.b4 axb3 19.axb3 Qd7 20.Rfd1 ]
17...a4 18.e4 Qd7 19.exf5 Rxf5 20.Re4 Raf8 21.Rxa4? After this move white is lost. Black traps the white queen and rook in a cross-pin. [21.Rae1 Rf4 22.Rxf4 is also better for black. 22...exf4 ]
21...Be7 22.Qg4 h5 23.Qe4 [23.Nxe5 Qd6 24.Nc4 hxg4 25.Nxd6 saves the rook but also loses 25...Bxd6 ]
23...Rf4 now black has a won game.
24.Qxe5 Rxa4 25.Re1 Bf6 26.Qxh5 Rxa2 27.g4 desperation
27...Qf7 28.Qh3 Bxb2 29.Re3 Ra3 30.Rxa3 Bxa3 31.Ng5 Qxf2+ 32.Kh1 Qe1+ 33.Kg2 Rf2+ [33...Qf1+ 34.Kg3 Qf2# mate is even quicker]
34.Kg3 Bd6+ 35.Kh4 Rxh2+ 36.Kh5 Rxh3+ 37.Nxh3 Qh1 White loses his knight or is mated after a few moves 0-1
