Garry Kasparov has just finished a whirlwind tour of Britain during which he gave simultaneous displays in Oakham, Oxford and London in the space of three days. The event at Oakham School was the most interesting, where he played eight opponents in the clock simul. Each player had 100 minutes to complete all their moves, with Kasparov facing the little problem that whenever he stopped to think, his clock might well be running on all eight boards at the same time.

I have always felt that the best strategy for the team facing a champion in such a display is to co-ordinate their efforts to produce synchronised moving, but as far as I know the Oakham team did not do so. Perhaps that explains why they lost 8-0, though Kasparov's excellent technique may also have contributed.

The two best games both saw Kasparov tempting his opponents into tactical adventures which led to his advantage in the endgame. In his game against Nicholas Pert, Kasparov allowed White to win two pieces for a rook in the complications that began with 13...Bd3, but he had seen through as far as 20...Rxa2 and realised that the black a-pawn would prove too strong.

David Garner's game was very similar. After 14 moves, he saw an opportunity for a series of exchanges. Perhaps when playing 15.Nxc6, White expected 17...Rxe4 with a more or less equal game, but Kasparov had it all under control with the clever 18...Red8! leading to a double rook endgame in which, despite initial appearances, Black always had the advantage.

Kasparov's technique in keeping the white rooks tied down to the defence of his weak pawns, then gradually advancing his own pawns and increasing his grip, is very instructive. At the end, White resigned without waiting for the decisive 38...Rff3, winning the pawn on h3 and leaving White's cause hopeless.
