Garry Kasparov made a subdued start to the Chess Olympics, drawing four games before scoring his first win. But when it came, it had been worth the wait.

Playing against the Czech top board, Hracek, Kasparov's explosive finish began with the diagram. It's White to play and win.

The answer was pure geomerty: 1.Bxd5! when 1...Qxd5 loses to 2.Qf4, 1...exd5 loses to 2.Qe3+ and 1...Rxf5 is met by 2.Bc6+!

Once the d-pawn was gone, Black had no chance. 23...Rxf5 loses to 24.Bxe6! and in the final position there was again no defence to the threat of Bxe6.

White: Kasparov

Black: Hracek
