Now it is Giri's turn to fire. 23. d4g7 Now everything is hanging, but above all the black king is  less safe than his colleague. 23... h3h2  24. d2g5 Xiong was playing on seconds, and is under a decisive attack. A  lot of people would have thrown in the towel here... 24... f8f5 The  second rook goes wild. At the same square. 25. g5g4  25... g8f7  26. g7b2  26... d6f4  27. b4b5  27... c6c7  28. g4g7 The decisive moment of the match. It seems as White is mating,  but this is not the case. I am not sure White would have found the winning continuation even in a classical game though. 28... f7e8  29. b2f6  29... h2g2 Just in time. 30. g1g2  30... b7e4  31. g2f1  31... f4d6 The king is almost fully secured. 32. f6h4  32... d6f8  33. g7g3  33... c7g3  34. h4g3  34... e4f3  35. d1d4  35... f8e7 Black is charge in the  endgame as the rooks do not have enough room to operate but Giri now  demonstrates impeccable defensive technique. 36. f1e1  36... e7b4  37. e1f1  37... b4e7  38. f1e1  38... f5h5  39. e1d2 The presence of opposite-colored bishops should be  enough for the draw. 39... e7f6  40. d4d3  40... f6g5  41. d3e3  41... e8d8  42. g3d6  42... h5h1 A practical approach by the American GM. Despite his young  age Xiong is always very rational. Black can push for the overall win of  the match with no risk. 43. c1h1  43... g5e3  44. d2e3  44... f3h1  45. e3d4  45... h1f3  46. d4c3  46... h7h5  47. a2a4  47... h5h4  48. c3b4  48... h4h3  49. a4a5  49... d8e8  50. a5b6  50... a7b6  51. c4c5  51... e8f7  52. c5b6  52... f7f6  53. d6g3  53... e6e5  54. b4c3  54... f6e6  55. c3d3  55... f3b7  56. f2f4 Just in time to swap all the important pawns. 56... e5f4  57. g3f4  57... e6d5  58. f4h2  58... d5c5  59. h2g1  59... c5b5  60. d3e2 Switching the roles of  the defenders. 60... d7d5
