The only inaccuracy of Najer in the whole game. But  taking into account the fact that it led to a victory in three moves, it  can hardly be criticized.
1. d2d4  1... g8f6  2. c2c4  2... e7e6  3. b1c3  3... f8b4  4. e2e3  4... e8g8  5. c1d2  5... d7d5  6. g1f3  6... b7b6  7. a1c1  7... c8b7  8. c4d5  8... e6d5  9. f1d3  9... b4e7  10. e1g1  10... b8d7  11. f3e5  11... d7e5  12. d4e5  12... f6d7  13. f2f4  13... d7c5  14. d3b1  14... d5d4 A double-edged position  arose in which both sides consistently carry out their plans. Najer wants  to mate his mighty opponent on the kingside, Anand answers in return with  the classical central break. 15. c3b5  15... d4d3  16. b5d4  16... a7a5  17. d1g4  17... g7g6 Black comes first with a novelty. 18. f4f5  18... c5e4 But this move is a mistake. 19. b1d3 A brilliant piece sacrifice! The attack more than compensates for the lost material. 19... e4d2  20. f5g6  20... f7g6  21. d3g6  21... g8h8 Anand finds the best defense, hiding behind his last  kingside soldier. 22. g6h7 The guard is removed! 22... f8f1  23. c1f1  23... e7g5  24. d4f5 Calmly bringing the last deserves into the attack. 24... d8d3  25. f1e1  25... g5e3 Anand managed to find counterplay even in a  situation where his king is barely holding on the edge of the abyss! 26. g1h1  26... e3h6
