Mumbai, Nov. 10 -- For a few seconds that may have felt like an eternity Vidit Gujrathi sat at the table, analysing the chess pieces, hoping for a way out. There was none. With a forlorn expression, he resigned against American grandmaster Sam Shankland. And with the 3.5-2.5 defeat, his journey at the 2025 Chess World Cup came to an end in the third round tiebreaks. Sunday was a mixed day for the Indian contingent in Arpora, Goa. Three players from the host country were competing in the third round tiebreaks, hoping to join the four who had already made it to the next round. While Gujrathi and SL Narayanan were beaten, Karthik Venkataraman managed to secure a spot in the fourth round. By most assumptions though Gujrathi was the favourite to win the third round tie against Shankland. The pair drew their two classical games on Friday and Saturday, taking the match into the tiebreaks. In the rapid format though Gujrathi started strongly with black pieces, winning the opening match. The world No.27 needed just a draw in the second match, but Shankland - world No.70 -managed to pull off a win to level the match. In the first game of the next round of tiebreaks, the players cancelled each other out in a draw. That is until Gujrathi blundered on the 53rd move to give Shankland the upper hand. Karthik, 25, became the fifth Indian to make it to the fourth round. He beat Romanian GM Bogdan-Daniel Deac (ROU) in the second game of the tiebreaks with black pieces. Having drawn the first rapid game with white pieces, he pinned Deac's king and cashed in on the extra bishop, winning in 43 moves. He will next take on the 13th seed Quang Liem Le of Vietnam....
