1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 Nc6 5.Nc3 d6 6.Be3 Nf6 7.Be2 Be7 8.0-0 a6 9.a4 0-0 10.f4 Qc7 11.Kh1 Bd7 12.Nb3 b6 13.Qe1 Bc8 14.Qg3 Bb7 15.f5 Kh8 16.Rad1 Rae8 17.fxe6 fxe6 18.Qh3 Bd8 19.Nd4 Nxd4 20.Rxd4 e5 21.Rc4 Qb8 22.Rd1 b5 23.axb5 axb5 24.Nxb5 Nxe4 25.Bd3 Nf6 26.Rh4 e4 27.Be2 Bc8 28.Qg3 Ba6 29.c4 Bxb5 30.cxb5 Bb6 31.Bf4 Qa7 32.Bxd6 Bf2 33.Qf4
33. .... Nd5 34.Qc1 It seems Hou has around 5 minutes left compare to Kosteniuk who has around 14 minutes. 34...Rc8 35.Qd2 Rfd8 36.Rxh7+ Kxh7 37.Qxd5 Qe3 38.Bg4 Ra8. Now it seems Hou is in losing position with an open king & dangerous 2 bishops pair.
39.Qe6 Kh8 40.Qe7 Qh6 41.h3 Qg6 42.Qe5 Bb6 43.Bh5 Qh6
It seems Hou Yifan is going for pawn promotion and position the 2 rooks into attacking.
44.Bg4 e3 45.Qe4 Qf6 46.Rd5. If Hou Yifan not careful, she could lose the queen with Rh5+ and followed b7 Be6+ again.
46....Ra1+ 47.Kh2 Qxd6+ 48.Rxd6 Bc7 49.Qf5 Bxd6+ 50.g3 Kg8 51.Qd5+ Kf8 52.Qf5+ Ke7 53.Qe6+ Kf8 54.Qf5+ Kg8 55.Qd5+ Kf8 56.Qf5+ It seems the perpectual check can't be avoided. ½-½
