Magnus Carlsen is almost sure of becoming the next chess world champion after he won for the third time in the World Championship match in Chennai against Viswanathan Anand on Thursday. In a sharp Nimzo-Indian, the 43-year-old Indian got a nice attacking position and had his chances, but there was never a clear mate. At some point Anand lost his way in the complications and blundered; on move 28 he had to resign and so Carlsen has increased his lead to 6-3. The 22-year-old Norwegian needs only a draw tomorrow to win the title.
