1. g1f3  1... g8f6  2. g2g3  2... c7c5  3. f1g2  3... b8c6  4. e1g1  4... e7e5  5. d2d3  5... d7d5  6. e2e4 This might be  Grischuk's rapid weapon, the reversed KID. 6... d5d4  7. a2a4  7... f8d6  8. b1a3  8... h7h6 The opening should not have been a surprise for Wojtaszek. 9. f3h4  9... g7g6 Depriving the knight of the f5 square, a form of  prophylaxis often used by Taimanov. 10. f2f4  10... e5f4  11. g3f4  11... f6g4 A necessary move. 12. h4f3  12... g6g5 This is all about the e5 square. If Black manages to seize  it, he will kill two birds with one stone by shutting down the white  light-squared bishop. 13. e4e5  13... d6e7  14. d1e2  14... g5f4  15. c1f4  15... h8g8  16. a3c4  16... c8e6  17. g1h1  17... d8d7 Wojtaszek can be  satisfied with the opening outcome. The position is dynamically balanced. 18. f3d2 The square strategy. Since the board is packed with pieces and  both sides have fixed wonderful outposts in the enemy camps the knights  try to occupy them. 18... e8c8  19. a4a5  19... e6d5 A good plan. 20. d2e4  20... d7e6  21. a1e1  21... c8b8  22. c4d6  22... g4e3 There you go, outposts, all of you are occupied! Time for some trades. 23. f4e3  23... d4e3  24. e2e3 A difficult to spot  blunder. 24... c6e5  25. d6f5  25... g8g6  26. e1e2  26... b8a8 A mistake in return. 27. e4g3 Trading Black's best piece. The knights clearly dominate. 27... d5g2  28. e2g2  28... e7f8  29. a5a6 Now Grischuk can definitely claim a serious advantage as  besides the better knight versus bishop he adds the better pawn structure  to his list of advantages. 29... b7a6  30. f1e1  30... f7f6  31. e3e4  31... e6d5  32. g2f2  32... d5b7  33. e4b7  33... a8b7  34. g3e4  34... c5c4 This can be named the last mistake. 35. d3d4  35... e5c6  36. c2c3 The pawn structure is stabilized in White's favor  and the weak black pawns start to drop one after other. 36... b7c7  37. f5e3 The first target is easily claimed. 37... a6a5  38. e1f1  38... a5a4  39. e3c4  39... f8e7  40. c4e3  40... a7a5  41. f1a1  41... a4a3  42. b2a3  42... a5a4  43. f2f5  43... d8b8  44. e3d5  44... c7d7  45. d5b4  45... c6d8  46. f5a5
