Round 11 at the 75th Tata Steel Chess 2013: World Champion Anand dropped the ball against former Women’s World Champion Hou Yifan. What seemed destined to become a model endgame victory turned tragic for the Indian Grandmaster when he decided to transpose a winning knight endgame into a drawn pawn endgame: After, for example, 42…h5 Black should be winning, but after Anand’s mistake 42…Nf5?, Hou Yifan found the narrow path to a draw with 43.Nxf5 Kxf5 44.a4 Ke6 45.g4! Kd5 46.Kc3 Ke4 47.Kc2! Kd4 48.Kb3 e4 49.b5 axb5 50.axb5 e3 51.Kc2 Ke4 52.Kd1!.
