The following games of Jan Timman's from the recent Sigeman tournament in Malmo, Sweden, demonstrate the sort of fighting spirit that it takes to win a GM tournament. They were not necessarily his best games from the event, but they were the most difficult for both players and make an interesting study. MG
J. Timman (2616) - E. Berg (2539) [E15]
14th Sigeman & Co/Malmo SWE (1) 2006
With the idea of Rd1, trying to create pressure on the d-pawn. White immediately threatens to give Black a pawn weakness by cxd5, since the Queen and Bishop will be attacking the Bishop at a6 - though in many cases Black does fine despite the isolated pawn.
A daring solution to Black's difficulties, sacrificing material in order to exploit the insecure position of White's king in the center.
White has great difficulties despite his piece advantage.
Though this allows Black to gain a strong attack along the c-file, White has foreseen a forced draw.
Going for perpectual check. White has no better.
Mistakenly trying to escape the draw, and that's all Timman needs.
Winning one of the pawns that really matter.
68. Nd5!! 1-0

threatening Qe1 mate and putting white practically in zugzwang.
Black will eventually force mate, for example:
