1. e2e4  1... e7e6  2. d2d4  2... d7d5  3. e4e5  3... c7c5  4. c2c3  4... b8c6  5. g1f3  5... d8b6  6. a2a3  6... c8d7 Berkes had played this line in his World Cup match against Vitiugov. 7. b2b4  7... c5d4  8. c3d4  8... a8c8  9. c1b2 The development of the bishop on e3 is also very popular. 9... g8e7  10. b1c3  10... c6a5  11. f1d3 [%c_effect d3;square;d3;type;Interesting;persistent;true] A new move at the grandmaster level. It certainly was prepared especially for this game. 11... a5c4  12. b2c1  12... a7a5 A critical move to challenge White's opening idea. 13. e1g1 [%c_effect g1;square;g1;type;GreatFind;persistent;true] 13... a5b4  14. a1b1 I suspect this was still preparation by Praggnanandhaa. 14... b6a7  15. a3b4  15... b7b5 A good plan: Black prepares to return the queen to b6 and maybe play the knight to c6 later. 16. h2h4 [%c_effect h4;square;h4;type;GreatFind;persistent;true] Useful prophylaxis against ...Ng6 and also a natural move to attack on the kingside. 16... a7b6  17. f1e1 [%c_effect e1;square;e1;type;GreatFind;persistent;true] I like this move a lot. The idea is to play Re2-a2. 17... h7h6 A defensive move that is necessary sooner or later. 18. e1e2  18... d7c6 [%c_effect c6;square;c6;type;Inaccuracy;persistent;true] This is too slow. The problem with Black's position is that it's impossible to defend without going for razor-sharp variations. 19. e2a2 White has a big advantage now. 19... c6b7  20. a2a5 [%c_effect a5;square;a5;type;GreatFind;persistent;true] Another great move. The rook cannot be captured. On the board, we have a typical \"French nightmare.\" 20... b7c6  21. d1e2 [%c_effect e2;square;e2;type;Inaccuracy;persistent;true] This is White's only mistake in the game. 21... g7g6 [%c_effect g6;square;g6;type;Inaccuracy;persistent;true] This gives White time to correct the mistake on the previous move. 22. b1a1 [%c_effect a1;square;a1;type;GreatFind;persistent;true] 22... e7f5  23. a5a6  23... b6d8  24. g2g4 [%c_effect g4;square;g4;type;GreatFind;persistent;true] Praggnanandhaa said in the post-game interview that this is the critical moment of the game. The cold-hearted computer already evaluates White's position as winning and also offers an alternative: 24... f5h4  25. f3h4  25... d8h4  26. d3c4 White is winning by force now. 26... b5c4  27. a6c6  27... c8c6  28. a1a8  28... e8d7  29. e2f3 The f7-pawn is attacked, and a knight sacrifice on d5 is coming. 29... f7f5  30. b4b5  30... c6c8  31. c3d5 [%c_effect d5;square;d5;type;GreatFind;persistent;true] 31... h4g4 The most stubborn defense. The alternatives lose immediately. 32. f3g4  32... f5g4  33. d5b6  33... d7c7  34. b6c8  34... c7b7  35. a8a6  35... b7c8  36. a6e6 After his brilliant previous game, White has achieved an easily winning endgame. Black's pawns are very weak and about to fall. 36... c8b7  37. e6g6  37... c4c3  38. g6c6
