1. d2d4  1... g8f6  2. c2c4  2... e7e6  3. g1f3  3... d7d5  4. g2g3  4... d5c4 "Maybe I should study some  Catalans with ...dxc4." (Grischuk) 5. f1g2  5... a7a6  6. e1g1  6... b8c6  7. e2e3  7... a8b8  8. f3d2  8... e6e5  9. g2c6  9... b7c6  10. d4e5  10... f6g4  11. d2c4  11... c8e6  12. d1e2  12... h7h5  13. f1d1  13... d8c8  14. e2f3 A novelty. At his stage Ding was an  hour ahead on the clock and Grischuk was severely worried about his king  safety. 14... b8b6 "An excellent move." (Grischuk) Instead of defending Black  sacrifices the exchange in return for light-squared domination. 15. c4b6  15... c7b6  16. h2h4 White sensibly decides to keep the h-file blocked. 16... g4e5  17. f3f4  17... e5g6  18. f4e4  18... f8e7  19. b1c3 At last Grischuk finds a moment to  develop his queenside. 19... e6f5 "Not the most accurate" ((Ding) 20. e4h1 "Very important. I finally thought I am more or less OK."  (Grischuk) 20... g6e5  21. f2f3 "[After this move] my position is not so promising."  (Ding) 21... f5c2 Temporarily disturbing the harmony in the enemy  camp. 22. d1d2  22... c2g6  23. h1g2  23... e8g8  24. d2d1  24... c8f5  25. d1f1  25... f5e6  26. c3e2  26... e5d3  27. g1h2 Another sensible, important move. 27... f8d8  28. e3e4  28... f7f5  29. e4f5  29... e6f5  30. e2f4  30... g6f7  31. f4d3  31... d8d3  32. c1f4 Again a sensible,  down-to-earth approach. Grischuk finishes the development and as he put  it, later made a draw from a position of strength. 32... e7h4  33. a1d1  33... d3d1  34. f1d1  34... h4f6 For the exchange Black has  enough: the a pawn and the bishop pair. 35. b2b3  35... g7g5  36. f4c7
