1.d4 Nf6 2.Nc3 d5 3.e4 dxe4 4.f3 exf3 5.Nxf3 Bf5 6.Ne5 e6 7.g4 Bg6 8.Qf3 c6 9.g5 Qxd4

More common Black moves here are 9...Nd5/d7/g8 and 9...Bh5. The text gives up a piece for a pawn mass that might prevail in an endgame.

10.Nxg6 hxg6 11.gxf6 gxf6 12.Be3 Qe5


[12...Qh4+ 13.Bf2 Qg5 14.Ne4 Qa5+ 15.c3 Nd7 16.Nxf6+ Nxf6 17.Qxf6 Rh5 18.Bd3 Re5+ 19.Kd2 Rd8 20.Kc2 Rxd3 0-1 Adams,S-Tan,K/Singapore ch prelims 1996/[Adams] (26)]

13.0-0-0 Nd7

[13...Qxe3+ 14.Qxe3 Bh6 15.Qxh6 Rxh6 16.Ne4 Ke7 17.Nd6 b6 18.Nc8+ Ke8 19.Bg2 f5 20.Rd2 Kf8? 21.Rd8+ 1-0 Peilen,M-Andre,K/cr 1986 (23)]

[24.Qb8+ is crushing. Black's Queen is immobilized by the need to prevent mate at d8; for example: 24...Ke7 25.b3 Bg7 a) 25...f5 26.Bg5+ f6 27.Bxf6+ Kxf6 28.Qxf8+ Kg5 29.Qe7+ Kg4 30.h3+ Kh5 31.Bf3+ Kh6 32.Qh4+ and mates.; b) 25...c5 26.Bf4 (threatening Bc7) 26...Ne5 (26...e5 27.Nd5+) 27.Bxe5 fxe5 28.Nd5+ exd5 29.Qxe5+ mates; 26.a3 Nxa3+ 27.Bxa3]

24...Ne5 25.Qf2 Bg7 26.Qd2 Rg4 27.Bb2 Qc7 28.Ne4 Kf8 29.h3 Rh4 30.Qf2 

[30.Bxe5! fxe5 31.Qg5 wins the Rook.]

30...Rh5 31.Qxa7 Nd7 32.Qa8+ Nb8 33.Ba3+ Kg8 34.Bd6 1-0
