At the age of 64, Viktor Korchnoi seems more exciting than in his youth. One of the great defensive and counter-attacking players, in his best years he always appeared reticent to launch attacks himself, yet he now seems to have lost all such inhibition. His win over Jan Timman from the Horgen tournament last week was a splendidly aggressive exhibition.

After surrendering the bishop pair in the opening, Timman's strategy was to establish his knight on the excellent d5 square and leave White's bishops aiming into thin air, but the surprising 23.Bh7!, threatening 24.Qxh6!! gxh6 25.Rg8 mate, exposed the fatal weakness in the plan. Timman won the bold bishop, but his king was too exposed to survive. 32.f7+! was a brilliant finish: 32...Kxf7 loses to Rxh7+, 32...Rxf7 loses to Rh8+, and 32...Qxf7 is met by Qc2! with the fatal double threat of Qxc8 mate and Rxh7.
