1. c2c4  1... g8f6  2. g1f3  2... e7e6  3. g2g3  3... d7d5  4. f1g2  4... f8e7  5. e1g1  5... e8g8  6. d2d3 I didn't know this move, which is humble in appearance, but this position has been tried many times by strong players, although overwhelmingly in rapid or blitz games. 6... c7c5 The main move. 7. f3e5 A trendy move. Giri faced this move in a classical game this year. 7... b8d7  8. e5d7  8... c8d7  9. e2e4  9... d5e4  10. d3e4  10... d7c6  11. d1e2  11... f6d7  12. f2f4 White's position already seems comfortable to me here, with more space. 12... a7a6 A new move. 13. a2a4 Useful prophylaxis against b7-b5. 13... d8c7  14. b1c3  14... e7f6 A useful move to tempt White into playing e4-e5, exchanging the light-squared bishops. Otherwise White can put the bishop on e3, develop the a1-rook, and it's not clear what Black can do in the meantime. 15. e4e5  15... c6g2  16. g1g2  16... f6e7  17. c1d2 The idea is to play Ne4 and put the bishop on c3. 17... a8e8 The rook is placed on this square in anticipation of the plan with f7-f6 (or f5), when the rook has the function of protecting the pawn on e6. 18. c3e4 An important moment in the game. 18... c7c6 The wrong plan. 19. e2f3  19... f7f5 Black needs to do something. 20. e5f6  20... g7f6  21. d2c3  21... f6f5  22. f1d1 This is not the most accurate. 22... d7b6 The best defense. 23. e4d2  23... c6f3  24. g2f3  24... e8d8  25. f3e2 The endgame is still much better for White. 25... d8d6  26. a4a5  26... b6d7  27. d2e4 A flashy move, but not the best one. 27... d6d1  28. a1d1  28... f8d8  29. e4d6  29... d7f6 This move leads by force to a winning advantage for White. There are two better alternatives. 30. c3f6  30... e7f6  31. d6b7  31... d8d1
