Chess: Keep pushing

'WHEN you don't know what to do', advised the Danish grandmaster Bent Larsen, 'push a rook's pawn.' In today's game (a half-hour tie- split from the Interpolis tournament) Anatoly Karpov pushed his a-pawn four times between moves 17 and 25 and he knew exactly what he was doing on each occasion.

After 16 moves, Vyzmanavin had a sound position and the bishop pair. His c-pawn was backward, but difficult to attack, his bishop on a6 was a little uncomfortable, but these problems seemed temporary. His real difficulty was that his natural freeing moves all had undesirable side-effects: b4 gives up the c4 square to a white knight; e5 allows both d5 and Nf5, while c5 allows d5. Karpov provoked a crisis with 17. a3] tempting c5 before it was ruled out by White's b4.

The next move of the a- pawn, 19. a4] shifted the black pawn from b5 to gain c4 for the white knight. 20. Nb5] was well judged, calculating that 23 . . . a6 could be met by 24. d6] followed by a5] Black moved his bishop from e7, to avoid attack by the d-pawn, but Karpov's next two a-pawn moves firmly cemented his advantage.

After 25. a6] Ba8, the black bishop was cornered and immobile. The rest of the game was a patient exploitation of that fact, culminating in 36. Qe8 excommunicating the bishop entirely.
