1. c2c4  1... e7e5  2. b1c3  2... g8f6  3. g1f3  3... b8c6  4. e2e4 Quite popular these days. 4... f8b4  5. d2d3  5... a7a6 Black intends to keep his dark squared bishop. 6. f1e2  6... d7d6  7. h2h3  7... b4c5  8. e1g1  8... e8g8  9. c1e3  9... c6d4  10. d1d2  10... h7h6  11. e2d1  11... f6h7  12. e3d4 Parting with the dark suared bishop while the light squared one has no obvious prospects may seem illogical, but Ding intended to hit the d4-pawn. 12... e5d4 Very principled again. It's nice to see young players of today not backing out of big strategic battles. 13. c3e2  13... d8f6  14. e2g3  14... b7b5  15. a1c1  15... b5c4  16. c1c4  16... c8e6  17. e4e5 Ding decided to secure a pawn majority on the queenside. 17... f6e7  18. e5d6  18... c7d6  19. c4a4  19... e6d7  20. f1e1  20... e7d8  21. a4c4  21... a6a5 It's amazing how Black manages to stay afloat with the help of little tactics. 22. a2a3  22... d7e6  23. c4c2  23... h7f6  24. b2b4  24... a5b4  25. a3b4 So, White got his poassed pawn going, but it's hardly a very important factor in the middlegame. 25... c5b6  26. g3e4  26... f6e4  27. d3e4 The d4-pawn is a target. 27... d8f6  28. c2c6  28... a8a2  29. d2d3  29... f6d8  30. d1b3  30... a2a3  31. e1b1  31... d8b8  32. d3b5 It seemed that Ding had finally been able to solve the riddle, but at the cost of taking alot of time off his clock. 32... e6b3  33. c6b6  33... b8a8  34. b1e1 It's not clear to me why that rook had to abandon the b-file, where it was supporting the pawn. 34... b3c2  35. f3d4  35... c2e4 The bishop managed to find its way around to capture an important pawn. The game remains roughly balanced. 36. f2f3  36... a3a1  37. b5f1  37... a1e1  38. f1e1  38... a8d8  39. b6a6  39... e4b7  40. a6a3  40... d8b6  41. e1e3  41... b7c8  42. d4c2  42... b6b8 Esipenko wisely avoids a queen trade to make life difficult for his opponent. 43. e3d4  43... c8e6  44. c2e3  44... f8c8  45. a3a6  45... c8c1  46. g1f2  46... d6d5  47. f3f4 A big error. Ding wanted to cover the dark squares, but his king becomes too exposed. 47... c1b1  48. a6b6  48... b8c7  49. b4b5  49... c7c1  50. b6b8  50... g8h7  51. d4d3  51... f7f5  52. f2f3  52... d5d4 The classic central pawn push decides the game in favor of Black. 53. d3d4  53... b1b3  54. f3f2
