Grandmaster Viswanathan Anand on Wednesday retained the world chess championship crown after drawing with Russian challenger Vladimir Kramnik in the 11th game, capping a remarkable victory in a tension-filled match here.Playing white, Anand did not give any chance to a resurgent Kramnik who had got a bit of life after winning the 10th game of the match.Anand finished the match with an overall score of 6.5-4.5 points, which means a handy two point lead for the Indian ace in the 12-game match.Kramnik, who had got a whiff of life after winning the 10th game of the match, could not do an encore with the black pieces and turned out to be a graceful loser in the end.Anand won three while Kramnik won one game in the 11 games played in the match while rest of the games were drawn.Anand, for the first time in the match, got his king pawn opening rolling and Kramnik was taken aback early even as he went for the sharp Sicilian defense.
