8/3/2010 – Her main rivals Humpy Koneru and Hou Yifan played each other in round four in Ulaanbaatar.

Meanwhile Zhao Xue had defeated the legendary Maia Chiburdanidze to take the sole lead with 3.5/4 and a 2788 performance. Round four report.

Round four under way at the FIDE Grand Prix in Ulaanbaatar

Zhao Xue (2462) - Chiburdanidze,M (2514) [A15]
5th FIDE GP w Ulaanbaatar MGL (4), 02.08.2010
1.Nf3 Nf6 2.c4 e6 3.b3 d5 4.Bb2 Nbd7 5.g3 b6 6.cxd5 exd5 7.Bg2 Bb7 8.0-0 Bd6 9.d4 Qe7 10.Nc3 a6 11.Rc1 0-0 12.Nd2 Rad8 13.Nc4 Bb4 14.Qc2 Rfe8 15.Ne3 c6 16.Rfd1 g6 17.Bf3 Bd6 18.Rb1 h5 19.Ng2 Ne4 20.Bc1 Ndf6 21.Bf4 Bc8 22.Bxe4 dxe4 23.Bg5 Bf5 24.Ne3 Rb8 25.f3 Bb4 26.Bxf6 Qxf6 27.Nxe4 Bxe4 28.fxe4 Qe6 29.Ng2 Qxe4 30.Qxe4 Rxe4 31.e3 Rd8 32.Kf2 c5 33.Kf3 f5 34.a3 Bxa3 35.Ra1 Bb4 36.Rxa6 Rd6 37.Nf4 Kf7 38.Nd3 Rde6 39.Ne5+ Kf6 40.Ra7 h4 41.gxh4 cxd4 42.exd4 Rxh4 43.Rf7+ Kg5 44.Rg1+ Kh6 45.Rd7 Rxh2 46.Kg3 Rb2 47.Nf7+ Kg7 48.Ne5+ Kf8 49.Kf3 Rxb3+ 50.Ke2 Ke8 51.Rb7

In this Double Fianchetto English game the legendary women's world champion Maia Chiburdanidze was doing okay in an endgame where she was temporarily two pawns up. In the above position 51...Bc3 or 51...Rb2 or 52...Rh3 or a number of other moves would be enough to hold a draw. But Black blunders: 52...Bd6? 52.Rc1 Kd8?? 53.Rd7+ and because of 53...Ke8 54.Rc8# 1-0.

At the press conference after the game Maia (picture above) said she had got a good position after the opening, but had given her opponent some chances. 21...Bc8 was a bad move. In the endgame she was good, and in spite of some inaccurate play had given Zhao Xue a very difficult task. "Then came my unexplainable blunder and, as a result – defeat." She said was tired and fed up with chess in general. "I have played chess for forty years – that is twice longer than some of our participants’ age."

After a rare variation of the Queen's Gambit White had been fighting to keep an advantage, but then thrown away her chances in time trouble. Now it was time for Black to take the initiative. Stefanova spent half an hour considering her next move: 42...Rxg2+ 43.Kd3 Nxb5 44.Rc5 Nd4 45.Rxa5 Nxf3 46.Nxb4 Nxh4 47.Rd5+ Kc7 48.Rxe5 g5 49.Re7+ Kd6 50.Rh7 Rg3+ 51.Kc4 Ke5

Now the game should be a draw, but the Chinese WGM loses control and is deftly punished for her mistakes by her Bulgarian opponent: 52.Nd5? (52...Re7 was required) 52...Kxe4 53.b4 Nf5 54.Nf6+ Ke5 55.Nxh5 Rh3 56.b5 f3 57.Kd3 f2+ 58.Ke2 0-1. "I was lucky to win this game," said Antoaneta, "I am not sure if it is correct – maybe there was a draw or perpetual in it for my opponent."

After facing some perils and defending successfully the Mongolian WGM had a draw on the board: 45...Rg5+ 46.Kxh6 d5 47.Rf3 Kf7 48.Re3 Rg8 49.Kh7 Rg7+ 50.Kh6 Rg8 with perpetual check. However she lost after misjudging (or miscalculating) the continuation: 45...h5 46.Re3+ Re5 47.Rxe5+ fxe5 48.Kxh5 e4 49.Kh4 Kf6 50.Kg3 Ke5 51.h4 d5 52.h5 Kf6 53.Kf4 Kg7 54.g5 Kf7 55.b3 Ke6 56.h6 Kf7 57.c4 dxc4 58.bxc4 1-0.

After the game Tatiana Kosintseva (above) said that the Archangelsk Variation may be a popular line these days, even at the highest level, but for her it had come as a surprise and had put her into a difficult situation. Batkhuyag said she had studied this variation at home, but was surprised by 10.a5. "Generally I think it is a good variant, Black has equality."

This is a theoretical draw, but the Indian grandmaster, the second strongest female player in the history of the game, forced her opponent to prove she knew how to play it. Humpy took it to the full fifty move limit before conceding the draw: 53...Kf6 54.Re4 Rb2 55.Be2 Kf5 56.Ra4 Ke5 57.Kf2 Rb3 58.Bf3 Rb8 59.Rg4 Rb1 60.Be4 Rb3 61.Ke2 Ra3 62.Bd3 Ra1 63.Kd2 Rh1 64.Kc3 Rc1+ 65.Kb4 Rd1 66.Bc4 Rd8 67.Rg5+ Kd4 68.Rg1 Rb8+ 69.Bb5 Rc8 70.Rd1+ Ke5 71.Bc4 Rh8 72.Rd3 Ke4 73.Kc3 Rh6 74.Bd5+ Ke5 75.Kc4 Rh4+ 76.Kc5 Ra4 77.Re3+ Kf4 78.Re1 Kg3 79.Bc4 Kf2 80.Re8 Ra5+ 81.Kd4 Rf5 82.Bd5 Rf4+ 83.Kd3 Rf5 84.Re2+ Kg1 85.Be4 Rf2 86.Re1+ Rf1 87.Re3 Rf2 88.Rg3+ Kf1 89.Rh3 Ke1 90.Bf3 Rd2+ 91.Ke3 Re2+ 92.Kf4 Rf2 93.Ke3 Re2+ 94.Kd3 Rd2+ 95.Kc3 Rf2 96.Rg3 Rh2 97.Be4 Kf2 98.Rf3+ Ke2 99.Kd4 Rf2 100.Rb3 Kd2 101.Ra3 Ke1 102.Bf3 Rd2+ 103.Ke3 Re2+ 104.Kf4 ½-½
