Tata Steel Masters: Arjun’s Worst Event, Third Loss, Three Rounds Left

Round 10 of the Tata Steel Chess Masters 2026 has turned into a defining and troubling moment for Arjun Erigaisi , as the Indian Grandmaster slumped to his third defeat of the tournament, deepening what is becoming his most difficult showing at Wijk aan Zee. With only three rounds remaining , the setback not only damages his position in the standings but also reportedly results in a significant rating hit , underlining how costly each loss is at this elite level.

Arjun went down to Vincent Keymer , who scored a clean 1–0 victory . Keymer handled the critical middlegame phase with greater precision, gradually taking control before converting without allowing counterplay. For Arjun, the defeat reflects a recurring theme of this event promising positions slipping away under pressure against top opposition.

The broader round proved decisive across several boards. Gukesh D strengthened his campaign by defeating Yağız Kaan Erdoğmuş (1–0) , keeping himself firmly in the title conversation. Fellow Indian Aravind Chithambaram VR also impressed, beating Nguyen Thai Dai Van (1–0) in a mature performance that showcased control and patience.

Elsewhere, Matthias Blübaum delivered one of the round’s biggest upsets by overcoming Anish Giri (1–0) , a blow for the Dutch star on home soil. Several high-profile clashes ended without a winner: Nodirbek Abdusattorov drew with Vladimir Fedoseev (½–½) , Hans Niemann split the point with R Praggnanandhaa (½–½) , and Javokhir Sindarov drew Jorden van Foreest (½–½) .

Round 10 Scores – Masters

• Abdusattorov ½–½ Fedoseev

• Blübaum 1–0 Giri

• Erdoğmuş 0–1 Gukesh D

• Aravind Chithambaram 1–0 Nguyen Thai Dai Van

For Arjun, the situation is now about damage control. A strong finish could still restore respectability, but with form wavering and confidence tested, the final three rounds will be as much a psychological battle as a chess one. In a tournament where margins are razor-thin, this stretch may define not just his event, but the narrative of his season.
