Black regroups. The d5 square is now open for the bishop and White's bishop pair is not important yet. 46. g4?! Nd6?! White weakens his kingside in an attempt to gain activity and Topalov misses the best reply in 46...Ne7! winning a pawn. In the final moves of the game 60...b3! 61.Rc3 Rd4! Anand makes a last attempt to win, setting a trap if Topalov attempts to push his b-pawn to promotion (61...b2?? 62.Rxc5! b1=Q?? 63.Ne6+ Kg8 [or Kh8] 64.Rc8+ Rd8 65.Rxd8#) but Topalov did not blunder into it. The position after move 11 had only been played once before. Prior to the game, Topalov asked for one minute of silence in memory of Andor Lilienthal, who had died the day before.
