World chess champion Garry Kasparov pushed challenger Anatoly Karpov to the brink of elimination from their title match Saturday with a flashy 41-move win in the 20th game.

Kasparov now leads the 24-game series 11-9 with four wins, two losses and 14 draws.Kasparov, playing white, combined speed and power to unleash a ferocious attack on the black king, which eventually caused his challenger huge material losses.

Karpov was forced to defend a very risky position with only seconds separating him from loss by forfeit.

The champion manipulated the game in his best crowd-pleasing style, sacrificing assets to strip his opponent of defenders, then invading to recoup his investment with interest.

The players exchanged a firm handshake at the end of the game as applause erupted from a capacity crowd of about 1,000.

Despite their long-running rivalry and the drama of the day's clash, the players remained onstage for several minutes, discussing the intricacies of the game.

The next game is Monday.
