Black finishes the development and solves his opening problems. 14. d3f5  14... d7f6  15. f5d3 Ding needs to keep more pieces on the board if he wants anything from the game. He manages to slightly weaken the opponent's position. 15... h7h6  16. f3h4 Immediately exploiting the weakening of the light  squares. 16... f6d5 Black is OK to sacrifice the exchange. 17. d3h7  17... g8h8  18. h4g6  18... h8h7  19. g6f8  19... h7g8  20. f8g6  20... d8f6  21. c2e4  21... c8e6  22. e1g1  22... a8e8  For the sacrificed exchange, Black has several advantages: active pieces,  the bishop pair, a superb knight and the better pawn structure. 23. g6h4  23... e6f7  24. e4g4  24... h6h5 Playing against the uncoordinated white pieces. 25. g4g3  25... e8e4  26. e3g5 Afraid that something terribly wrong may happen on  the kingside, Ding rightly sacrifices a pawn. 26... f6e6  27. h2h3  27... b6d4  28. h4f3  28... d4b2  29. a1b1 Black won a couple of pawns anyway, but his opponent manages to stabilize the position on the kingside and bring  his rooks into life. 29... e4e2  30. g5d2  30... e6f6  31. d2a5  31... d5f4 Once again the black pieces seem very  frightening. 32. a5c7  32... e2c2  33. g1h2 The culmination of the game and the  match.
