Trouble in the middlegame: IM Anna Ushenina was lucky that her opponent ...


... GM Nadezhda Kosintseva missed a clear win and let Anna slip away with a draw

In the second game Anna sacrificed a pawn and, after Nadezhda some imprecise moves by her opponent won it back with a decisive advantage. For the first time in her life the 27-year-old Ukrainian IM has advanced to the semifinals of such an event.

Former women's world champion Antoaneta Stefanova (Bulgaria) lost her first game at this championship. She was defeated by Marie Sebag (France) in a Closed Anti-Marshall, where Stefanova, playing black, obtained a small advantage. However, she did not utilize all the benefits of her position and allowed White to make a break in the center. After that Stefanova lost the thread of the game and started making mediocre moves, while her opponent played flawlessly and increased the advantage. Being in time trouble Stefanova committed a blunder and soon resigned.

In the second must-win game the Bulgarian GM turned the tables...

In their first encounter in round four Zhao Xue (China) and Harika Dronavalli (India) played a good positional game. The Indian demonstrated an opening variation that was specially prepared for the championship, and equalized easily. The game quickly transposed to a symmetrical ending, where Black sacrificed a pawn for the initiative. However, White parried all threats, and the game ended peacefully.

The second game between was very dramatic. The Indian was better after the opening, but then started to make mistakes and lost a pawn. After a long maneuvere Black won another pawn. By that time White’s position was basically hopeless. But the Indian player began to set up traps...

Ju Wenjun (China), playing white, selected a very sharp variation of the King's Indian against her compatriot Huang Qian. In the previous match Ju had faced this line as black against Natalia Zhukova, and probably liked White’s options. However, it seems she hadn’t studied it well enough. White made an exchange sacrifice early in the game, but did not receive full compensation for it and were forced to defend. Black returned the exchange and kept an extra pawn, however, Huang Qian was unable to convert her advantage and eventually had to settle for a draw.

The second game was the shortest of the round and, possibly, the championship. The players went for a peaceful opening variation and agreed to a draw on 17th move. The all-Chinese quarterfinal will continue tomorrow in the tiebreak.
