India's Viswanathan Anand beat challenger Vladimir Kramnik again on Tuesday to put another nail in the coffin of the Russian challenger's fast-disappearing hopes of reclaiming the chess world championship. The win - Anand's third in four games - gave the defending champion a 4.5-1.5 lead in their 12-game match. Such a streak is virtually unheard of in world championship match play, where the vast majority of games are drawn. When Kramnik defeated then-world champion Garry Kasparov in 2000, for example, he won two games, while the other 13 were drawn. Kramnik lost the world championship to Anand last year. Kramnik, who has never before lost three games out of four, has slim chances of digging himself out of his hole with only six games to go - three of them with the white pieces. That means Anand can afford to keep drawing in the remaining games. Anand's ninth move, in a Classical Nimzo-Indian, was a prepared novelty that he later called “interesting because it forces him to start thinking very early.” Former world champion Anatoly Karpov of Russia said that “Kramnik's reaction was not good.” Anand will have the white pieces in game seven on Thursday.
