Indian Grandmaster Dronavalli Harika went down to former world champion Alexandra Kosteniuk in the sixth round of the FIDE Women's Grand Prix chess tournament at Lausanne in Switzerland to slip to the third spot.

The Indian no.2 was out manoeuvred by the Russian in a Berlin defence game in 55 moves late last night.

It was the first loss for Harika in the tournament after two wins and three draws. The world no. 9 Harika will face Zhansaya Abdumalik in the seventh round tomorrow.

Meanwhile, Russia's Alexandra Goryachkina and her compatriot Alena Kashlinskaya moved to joint lead with four points.

The strong tournament featuring 12 players, including world champion Wenjun, is the third in the series of four Grand Prix from which two with the highest points tally would qualify for the next candidates event.
