Kf4 ½–½A draw by threefold repetition (with perpetual check). Anand moved 40. Rh8+?, hoping to repeat moves in order to make time control. However, this a mistake that lets the Black king escape. It was better to play 40. Re4 b4 41. Rxa7 b3 42. Rb7 b2 43. Kh2 Qc1 44. Ra4 Nd7 45. Rab4. Anand missed a chance to win when he played 64. Kg3?. A winning move was 64. Rdd7 a3 65. Kg3 Qa1 (65...b2 66.

To avoid unnecessary complications, Anand played 25...Nd4?! but the best chance was in 25...Bxa6 likely followed by 26.Qxc6 Qa1+ 27.Kf2 Qxa2+ 28.Kg3 Qa3! 29.Qa8+ Qf8 30.Qxa7 Be5+ 31.Kh4 Qf1 32.g3 Bc8 33.g4 Bf6+ 34.Nxf6+ Qxf6+=. Anand subsequently equalised the game with 45...Nc4! It was likely that Topalov missed this move.
