Indian Grandmasters Vidit Gujrathi and S P Sethuraman bowed out of the Chess World Cup after defeats against Ding Liren of China and Anish Giri of Holland respectively in the tiebreak games of the third round here.
The ouster of the last two remaining Indians ended the challenge in the biennial event. Earlier, five-time world champion Viswanathan Anand, B Adhiban, P Harikrishna, Murali Karthikeyan and Deep Sengupta had lost in the knockout event.
Sethuraman was the closest to advancing to the pre- quarterfinal but he was unlucky in the second game under normal time control.
After attaining a winning position, the Indian could not hold on to his nerves and allowed Giri to get away with a half point after some subtle defense.
It was a tough battle for Gujrathi in the rapid tiebreak games. After drawing the first game, the Indian was looking fine in the second rapid game but Ding Liren came up with a fine plan to win a piece.
While the position was still volatile, the Chinese was quite up to the task in converting his extra material in to a full point. Gujrathi, who had been at the top his game thus far in this world cup, lost by 1.5-2.5 margin.
The third round in fact witnessed the biggest chunk of upsets in this World Cup as world champion Magnus Carlsen of Norway and highly regarded Vladimir Kramnik of Russia and Hikaru Nakamura of United States bowed out of the competition.
For Carlsen it was a tough call to win with black on demand against BU Xiangzhi of China and the Chinese drew quite effortlessly to sail in to the next round under normal game itself.
The shocker was the ouster of Kramnik at the hands of former star Vassily Ivanchuk of Ukraine who rose up just in time to remind the world that he cannot be ruled out.
Nakamura fell prey to some adventurous play against Vladimir Fedoseev of Russia.
Sethuraman was quite unlucky as he failed to convert a winning position against Anish Giri under normal time control.
Therapid tiebreaker was evenly matched as Giri won the first game and Sethuraman equalised but once it reached the 10-minute game, Giri was a cut above as he first won with white piece and then was spot on to find counter play and win another game as black.
