1. g1f3  1... g8f6  2. c2c4  2... c7c5  3. b1c3  3... d7d5  4. c4d5  4... f6d5  5. e2e3  5... e7e6  6. f1c4  6... f8e7 An achievement for Grischuk. He deprived his opponent of his  Gruenfeld bishop. 7. e1g1  7... e8g8  8. d1e2  8... b8c6  9. f1d1  9... b7b6  10. d2d4  10... d5c3  11. b2c3  11... d8c7  12. e3e4  12... f8d8 A position similar to the Queen's  Indian Defense came on the board. The plans remain the same as in the  Gruenfeld though: White would try to make use of his superior center and  more space to attack on the kingside, while Blackwould be looking for  counterplay on the opposite wing and eventual trades on the open files. 13. c1e3  13... c6a5  14. c4d3  14... c8b7  15. h2h4 Again, a very typical move against the  Gruenfeld where White is ready to hit the enemy fianchettoe with h4-h5.  But here too, it helps the attack as it prepares Nf3-g5. 15... b6b5  Vachier-Lagrave uses the first possibility to free himself. 16. d3b5  16... b7e4  17. d4c5  17... e4f3  18. e2f3  18... e7c5  19. e3f4 This additional possibility was not here had  Black had taken on c5 first. 19... c7b7  20. f3e2  20... b7e7  21. h4h5  21... c5d6 Sensibly swapping off the bishop pair. 22. f4d6 Grischuk is OK with it as he gets the open file in return. 22... d8d6  23. d1d6  23... e7d6  24. a1d1  24... d6c5  25. d1d7 White sacrifices a pawn and starts attacking on both flanks. This situation somehow reminds me of  the famous Rubinstein-Tarrasch game where the great Polish GM also  sacrificed a pawn or two for similar domination. Grischuk has more active  major pieces and is ready for the kingside assault. But there is also the  excluded black knight on a5, which may often fall victim to the enemy  pieces (Tarrasch also had exacty the same knight). 25... c5c3  26. e2d1 As usual, the Russian GM was very low on time and  wanted to play somewhat safe. 26... h7h6 Vachier-Lagrave grasps his chance! 27. g2g3  27... a8f8 And plays  solidly in return. 28. d7a7  28... a5c6  29. a7d7  29... c6e5  30. d7d8 Once more, the extra careful approach by Grischuk. He keeps a solid edge, without any risk. 30... c3c7  31. d8f8  31... g8f8  32. a2a4  32... f8e7  33. b5e2 A nice move which shows the  superiority of the bishop over the knight. This light-squared bishop in  particular was a favorite of Rubinstein as well. Now that his king is  secure, Grischuk wants to support the advance of his outside passer. 33... c7c3  34. d1b1  34... e5c6  35. b1b7
