Grandmaster Nihal Sarin pulled off a stunning comeback against Samuel Sevian and gatecrashed into the semifinals of the $500,000 Chess.com Global Championship Finals on Thursday.
Trailing 1.5-2.5 after the first set of four rapid online games on the previous night, Nihal bounced back to win the first two games and drew the next two for a remarkable 4.5-3.5 victory.
By reaching the semifinals, Nihal is assured of $50,000.
The rules provide for a tie-breaking Armageddon game in case of a 4-4 deadlock. But once Nihal fought back from a seemingly lost position in the final game to settle for a draw in a winning position.
For a place in the final, the 18-year-old Kerala boy plays Dutch Grandmaster Anish Giri while Hikaru Nakamura faces fellow-American Wesley So.
