BONN, GERMANY -- World chess champion Viswanathan Anand of India took a commanding lead over challenger Vladimir Kramnik on Monday when the Russian handed him a victory by making a horrible blunder under time pressure.

The win gave Anand a 3 1/2 to 1 1/2 point lead after five games in their 12-game match. It was Anand's second victory with the black pieces; the other three games have been drawn.

Kramnik called his situation "difficult but not completely hopeless."

Anand repeated the same line of the Meran Variation that brought him spectacular success in game three but varied from that game on move 15, thus sidestepping anything that Kramnik and his team might have come up with in the meantime.
