1. d2d4  1... g8f6  2. c2c4  2... g7g6  3. h2h4 "Just an interesting line for White." (Grischuk)  3... c7c5 "The most principles line" (MVL) 4. d4d5  4... b7b5  5. c4b5  5... a7a6  6. e2e3  6... f8g7  7. b1c3  7... e8g8  8. g1f3  8... d7d6  9. a2a4  9... c8g4 "This cannot be so bad for me  as the bishop is quite annoying." (MVL) This is the main reason why Black  chose to switch to the Benko gambit. 10. a1a3 "Unexpected, but probably  good." (MVL) 10... a6b5  11. f1b5  11... b8a6  12. e3e4  12... a6b4  13. b5e2  13... f6d7  14. e1g1  14... d8b6  15. f1e1 "Quite a stupid move." (Grischuk) 15... b6b7 A typical Benko position arose. Black has compensation for  the pawn thanks to his active pieces and is ready to open the play on the  kingside with f7-f5. 16. c1g5  16... g4f3  17. g2f3 A suprise for Black. 17... d7e5  18. e1f1  18... c5c4  19. b2b3 Missed by Black but he now plays simply brilliantly: 19... f8c8  20. g5d2  20... b4d3  21. f3f4  21... b7b4  22. c3b1  22... c4c3  23. f4e5  23... d3b2 Fantastic concept. Mind that Black should have foreseen this and the remaining well in advance. This was missed by  Grischuk who thought he is winning at this stage of the game. 24. d1c2  24... c3d2  25. c2b2  25... b4e4  26. b2d2  26... c8c2  27. d2d3  27... c2e2  28. d3e4  28... e2e4  29. e5d6  29... e7d6  30. b1d2  30... e4g4 In the forcing line Black wins  the pawn back and is much better thank to his better minor piece and more  active pieces. 31. g1h1  31... g4h4  32. h1g2  32... h4d4  33. d2f3  33... d4g4  34. g2h3  34... g4b4  35. f1b1  35... a8c8  36. h3g2  36... c8c3 The white pawns are too dangerous, therefore Black needs to  play extremely energetically to prove the win. Vachier-Lagrave is up to  this difficult task as well
