Short - Timman Tilburg, 1991
7/30/2003  
White to move
Solution: In this well known position, English GM Nigel Short conceived a novel and somewhat humorous solution. He launched his winning plan with 31.Kh2 Rc8 32.Kg3! Rce8 33.Kf4! Bc8 (too late) 34.Kg5!. At this point, Jan Timman resigned himself and the game to the inevitable, as 34...Kh7 35.Qxg6+ Kh8 36.Qh6+ Kg8 37.Kf6 ends with the same ignominious mate on g7.

Solution: In one of the most instructive endgame positions ever, American virtuoso Harry Nelson Pillsbury surprised his opponent with 29.c6! Kd6 (if 29...axb5, then 30.c7 wins) 30.fxe6! Nxc6 (if 30...axb4, then 31.e7 Kxe7 32.c7 ) 31.Nxc6 Kxc6. Now, Pillsbury continued with a precise clearance sacrifice, after which the game is all but over: 32.e4! dxe4 33.d5+ Kd6 (if 33...Kxd5 34.e7) 34.Ke3 b4 35.Kxe4 a4 36.Kd4 h5 37.gxh5 a3 38.Kc4 f5 39.h6 f4 40.h7 1-0

7/10/2003  
White to move. This was game eight of the world championship match.
Solution: Fischer was not the sort of player to let an opportunity pass and he won a pawn and the game by playing: 20.Nd5! Qxd2 21.Nxe7+ Kf8 22.Rxd2 Kxe7 23.Rxc4. The rest of the game went: 23...Rb1+ 24.Bf1 Nc5 25.Kg2 a5! 26.e4 Ba1 27.f4 f6 28.Re2 Ke6 29.Rec2 Bb2 30.Be2 h5 31.Rd2 Ba3 32.f5+ gxf5 33.exf5+ Ke5 34.Rcd4 Kxf5 35.Rd5+ Ke6 36.Rxd6+ Ke7 37.Rc6 1-0

Andruet - Spassky Koblenz, 1988
5/20/2003  
Black to move
Solution: On his birthday in 1988, Spassky cranked out the brilliant 25...Qf3!! and White resigned, since after 26.gxf3 Nexf3+ 27.Kh1 Bh3, he cannot prevent 28...Bh2#.
