1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1c4  3... f8c5  4. c2c3  4... g8f6  5. d2d3  5... d7d6  6. e1g1  6... a7a6  7. a2a4  7... c5a7  8. f1e1  8... e8g8  9. h2h3  9... c8e6  10. c4e6  10... f7e6  11. b2b4 A fashionable line at the top level these days. It  seems as Black should have rich counterplay along the semi-open f-file but things are not as simple. 11... f6h5  12. a1a2  12... d8e8  13. b1a3  13... h5f4  14. c1f4  14... f8f4  15. a3c4  15... e8g6  16. b4b5  16... a8f8 Just in time to transfer the rook to the  correct side of the board and avoid the consequences of the pin along the  a-file. 17. c4d2  17... c6e7  18. d3d4 Once again hoping to lock the bishop. 18... g6f6 To which Grischuk strongly disagrees. 19. d4e5  19... d6e5  20. b5a6  20... b7a6  21. d1e2 Finally, Caruana could not solve the  problem of the a7-g1 diagonal, but at least created some weaknesses to  work on. Strategically, White should have the advantage because of the  crippled black pawn structure but the continuous delicacy of the white  king's position makes the game roughly balanced. 21... a6a5  22. e1f1 The  weak point on f2 needs overprotection. 22... g7g5  23. d2c4  23... e7g6  24. f3h2  24... f6g7  25. e2d3  25... g6h4  26. h2g4 Caruana is fixated to his plan and misses a good opportunity. 26... h7h5 Now White also wins a pawn, but the bishop remains on the  diagonal and Grischuk is in time to open the kingside. 27. g4e5  27... g5g4  28. h3g4  28... h5g4 This pawn wants to go even further. 29. d3g3  29... g7g5  30. a2e2  30... g8g7  31. e5d3 The game remains extremely sharp and any inaccuracy  can be the last one. Needless to say, both players were very short of time already here. 31... f4f6 Grischuk commits the first inaccuracy, which  led him... straight to the victory. 32. g3c7 The obvious capture is not the best! 32... f8f7  33. c7e5 One more obvious move and this time it is a lethal  mistake. 33... g5h6 That is the thing. The queen is better placed along the  h-file. Grischuk is mating now. 34. e5g3  34... g7h8 The king should be away from the g-file. 35. e2b2  35... h4f3 Now it is a forced win after: 36. g2f3  36... g4f3  37. f1b1  37... f7g7  38. g3g7  38... h6g7  39. g1f1
