46. b3! White will lose a tempo on the queenside and win on the kingside after Black is forced to play either ...Kh8 or ...Kf8. For example: 46...a6 47. a3 a5 48. a4 Kh8 49. h6 gxh6 50. Kxh6 e4 51. g7+ (The point - It is important that this move is with check or White would be a tempo behind.) 51...Kg8 52. Kg6 e3 53. h5 e2 54. h6 e1=Q 55. h7#  Black resigns.

In the semi-final GM Yu Yangyi and Wei Yi drew five out of six games, but Wei Yi's one victory was enough to win the match.

In the final, Wei Yi won a complicated battle in the Ruy Lopez against Bu Xiangzhi.
