Top-rated Grandmaster Koneru Humpy suffered a shock defeat at the hands of Natalia Zhukova of Ukraine in the first game of the second round of world women's chess championship here today.
It turned out to be a bad day in office for the highest rated girl in the fray as she could not find her rhythm and now finds herself in a must-win situation with black pieces in the return game to stay in the knockout championship.
While Humpy faces ouster threat, the other remaining Indian Grandmaster D Harika made early inroads to the pre-quarterfinals defeating Elina Danielian of Armenia in her first game of the second round.
At the top of the tables, defending champion Yifan Hou of China remained on course for third round appearance with an easy victory over experienced Monika Socko of Poland. The 18-year old Chinese was a picture of confidence as she thwarted the attempts for complications by Socko and recorded a smooth victory with black pieces.
Veteran Grandmaster Pia Cramling of Sweden also won her game at the expense of Irina Krush of United States and is now sitting pretty along with the other first game winners Zhao Xue of China and Mariya Muzychuk of Ukraine.
Humpy faced the Tarrasch defense against Zhukova and it was not surprising as the Ukrainian's husband is a renowned expert of the variation. Surprisingly enough, the players spent some time in the opening although much of the game was theoretical.
Humpy felt the heat on the 22nd move when a correct move would have held the position together and already it existed as a game had been played till that position. It was clear from here that the opening surprise by Zhukova had paid off well as the Indian continued to struggle even as there were mutual mistakes in the remainder of the game.
