Rd7 Nxa2 23. Bxb7 Re8 24. Bxa7 white piece especially the bishop pair look strong but because of both pawns on one side the game white advantage is minimal 22. fxe3 Rb8 23. Rd7 b6 24. Rxa7
White is a pawn up but his pawn formation looks weak) 21... Nf4 22. Bf1 h5 23. f3 a6 24. Kf2 Li Tian improve his king position towards the center and ready for endgame battle 24... Rc8 25. Rd2 25. c4! is probably better because its take the d5 square from black's knight and restrict black to advance his b-pawns with b5 25... Rc7 26. a3 26. c4! again look stronger 26... Rd7 27. Kg3 Nd5 28. Bf2 Kf8 29. c4 Nb6 30. Rxd7 Nxd7 White has bishop pairs against black's knight+bishop. 31. Bd4 Ke7 32. Kf2 hxg4 33. hxg4 Kd8 34. Ke3 Ke7 35. Bc3 Bc2 36. f4 Bd1 37. Bh3 Nb6 38. Kd3 Kd7 39.
