Jonathan Speelman had an excellent win against Viktor Korchnoi in the first round of the New York leg of the Intel Speed Chess Grand Prix

Their first game - with each player allowed 25 minutes for all his moves - was a 61-move draw full of excitement from start to finish. With Speelman playing Black, the game opened 1.d4 e6 2.c4 b6 3.e4 Bb7 4.f3 Bb4+ 5.Bd2 Bxd2+ 6.Qxd2 Nh6! 7.Nc3 0-0 8.0-0-0 f5. His weird strategy did not equalise, but it was worth a few minutes on the clock.

An ingenious combination later won Korchnoi two knights for rook and pawn, but the knights seemed to trot in circles while Speelman's pawns galloped down the board.

Just as Korchnoi's game looked hopeless, he set a fine trap and swindled his way into an endgame two pawns up. Speelman then showed good technique to hold the draw - a fair result, all things considered.

After game two was also drawn, a play-off was needed. Speelman (White) had six minutes; Korchnoi had five, but needed only a draw to go through to the next round. Here is what happened. Five moves from the end, Black looks secure, but Speelman seeped in beautifully for a quick mating attack.

White: Speelman Black: Korchnoi
