India`s Viswanathan Anand retained the title with a 24-move draw against Russian Vladimir Kramnik in the penultimate game of the 12-game World Chess Championship final in Bonn today. The Indian Grandmaster, playing with white pieces, took an unbeatable 6.5-4.5 lead to retain the title. Needing just half a point, Anand drew after 24 moves as Kramnik failed to find a win despite trying to complicate the game. Anand earlier won three games -- the third, fifth and sixth -- and lost the 10th game in a match that looked one-sided till Kramnik brought back some life with a win in 10th game. The two players shared the purse of 1.5 million euros equally.
