The most dramatic happening of the week has been for a Russian Irishman to play the starring role in The Cherry Orchard. We are, however, talking more checkmate than Chekhov here, for the Monarch Assurance International has just finished at the Cherry Orchard Hotel, Port Erin, on the Isle of Man, and the winner was Alexander Baburin, the former Moscow grandmaster now resident in Dublin.

The event, which attracted a dozen grandmasters, won won by Baburin with the fine score of 8 out of 9, two points ahead of the runners-up, Liss (Israel) and Hebden (England). The joint British Champion, Matthew Sadler, was among the group sharing fourth place.

Baburin, like most Moscow-trained grandmasters, has a polished professional style combining a well-rehearsed opening repertoire with as high a level of aggression and energy as positional correctness allows. His first-round win is a good example. When White played 15.g4 and followed it with 18.f4, he must have had high hopes for his K-side initiative, but after Black's accurate 16 ... g5 and 18 ... f5, it was he who gained the advantage on that wing.

Black's 26 ... Qe7! was designed to meet the threat of 27.b5, but White must have missed the idea of 27.b5 Nxd4! 28.Rxd4 Qxc5 29.Bf2 Rxf2! At the end 44.Ke1 Qg1 is mate.

White: B. Baum

Black: A. Baburin

Matthew Sadler's hopes of first place vanished after a good start, with too many draws and a loss to Andrew Ledger. He did, however, play one characteristically forceful game to beat Tony Kosten.

White's 11.g4 and 12.Bd3 began to look very dubious when Sadler broke open the centre and sacrificed a pawn with 15 ... d4! Black's 21 ... Ncxd4! exploited all White's weaknesses: 22.fxe5 Nf3+ wins a piece. After White's final move, 23 ... Rxd4 24.fxe5 is not too bad for him, but 23 ... Qe7! with its threat of Qh4+ was fatal.

White: A. Kosten
