Nihal Sarin Upsets Erigaisi at Chennai Grandmasters

At the Quantbox Chennai Grand Masters 2025 chess tournament, Nihal Sarin secured his first classical-format win by defeating top-seeded Arjun Erigaisi in a dramatic fourth-round game marked by a double Queen sacrifice. This came after a difficult start for Nihal, who lost to Vincent Keymer in round one. German Grandmaster Vincent Keymer leads the tournament after four rounds, staying unbeaten and a point ahead of the field. Despite his loss, Erigaisi remains among the top contenders, though his live world ranking has slipped. The tournament features an elite international field and offers crucial FIDE Circuit points, with fluctuating fortunes among the top players. In the Challengers section, Indian Grandmaster Abhimanyu Puranik has emerged as the sole leader after four rounds.
