1. d2d4  1... g8f6  2. c2c4  2... e7e6  3. g1f3  3... d7d5  4. g2g3  4... f8e7  5. f1g2  5... e8g8  6. e1g1  6... d5c4  7. d1c2  7... a7a6  8. a2a4  8... c7c5  9. d4c5  9... e7c5  10. c1f4  10... b8c6  11. b1d2  11... f6d5  12. d2c4  12... d8e7 A logical novelty. Grischuk  keeps the knight in the center in order to control the Catalan bishop. In  the process he protects the dark-squared bishop, connects the rooks and is ready to finish the development. 13. f4d2  13... c8d7  14. f3g5 Provoking a slight weakening on the kingside... 14... f7f5 ...which Grischuk is OK with. 15. g5f3  15... c6b4  16. c2d1  16... f5f4 Black  is playing for the initiative himself. 17. c4e5  17... d7e8  18. a1c1 Wojtaszek finds an interesting way to activate his  rook. 18... a6a5  19. c1c4 White wants to relief the pressure on the kingside  and force the trade of the f4 pawn. In the future he may use the rook for  a kingside hunt. 19... b7b5 In return Black plays all over the board and tries to active his light-squared bishop. 20. a4b5  20... e8b5  21. c4e4  21... a8d8 Now Grishuk takes over the initiative.  Wojtaszek's main problem is that the rook cannot leave the e4 square as  the pawn on e2 demands protection. And it is very packed in the middle of  the board. 22. d1c1  22... f4g3  23. h2g3  23... d5f6  24. d2g5  24... e7c7  25. g5f6  25... g7f6  26. e5g4 The only  chance that White has is connected with the attack against the weakened  black king. 26... d8c8 Creating the threat of a capture on f2. 27. g1h1  27... c7g7  28. g4h6  28... g8h8  29. c1f4  29... b5d7  30. g3g4 All these moves are very consistent with the general  plan of a kingside attack, but wrong. 30... b4d5  31. f4h2  31... c8b8 It is very hard to call this obvious move a mistake. Grischuk activates his rook and hits the weakness on b2. 32. g4g5  32... f6g5  33. h6f7 Wojtaszek lived to deliver this blow. It does not win the  game but provides enough attack to keep the balance. 33... g7f7  34. f3g5  34... f7g6  35. g5h7 The point behind the sacrifice. The black king  is stripped. 35... g6h7 Grischuk decides to give back the queen at  once but to save-guard his Majesty. 36. e4h4  36... h7h4
