Open Section: Spain vs India (1-3) - Board 1: David Anton Guijarro vs Praggnanandhaa R
Praggnanandhaa outplayed David Anton Guijarro from the opening and built a huge time advantage, but a pair of inaccuracies let the evaluation slip and the game ended in a draw.
The Queen's Indian Defense produced a typical structure: Praggnanandhaa played 7...dxc4 and developed quickly, while Anton Guijarro pushed 18.e5 to gain space. Black responded with 18...b4, starting queenside counterplay.
The critical moment came on move 25 when Anton Guijarro played 25.Qa3, an inaccuracy; the engine preferred 25.Rxd3. Praggnanandhaa then erred with 29...Qd4, where 29...Rfb8 was better. The game simplified into a draw after 38 moves.
Despite the missed chance, Praggnanandhaa's opening preparation and time management were impressive, and the draw contributed to India's 3-1 win.
Open Section: Spain vs India (1-3) - Board 2: Arjun Erigaisi vs Maksim Chigaev
Arjun Erigaisi won his first game of the Olympiad, beating Maksim Chigaev in 36 moves after building pressure on the kingside and exploiting weaknesses.
The game began as a Queen's Indian Defense: Opocensky Variation. Arjun played 14.d5, which the engine slightly disliked, preferring 14.O-O, but Black soon equalized with 14...Bxc3+ and 15...e5.
Chigaev made several inaccuracies: 28...Rxf1 (better was 28...Qd6) and 31...Qd6 (better 31...Qf7). Then came the decisive blunder 33...Nxh5, where 33...Qf8 was necessary. Arjun punished it with 34.Nxe5+ and after 34...Ke7, 35.Qh7+ Ke8 36.Qf7+ and Chigaev resigned.
Arjun's win gave India an early lead in the match.
Open Section: Spain vs India (1-3) - Board 3: Jaime Santos Latasa vs Nihal Sarin
Nihal Sarin made a solid draw with the black pieces against Jaime Santos Latasa in a Philidor Defense: Lion Variation.
The game was balanced throughout. Santos Latasa played 6.a4 and 10.Ba2, but Nihal equalized with 10...a5. After a queen trade on move 19, the position was dead equal and the players agreed to a draw after 30 moves.
Nihal's draw kept India on track for the match victory.
Open Section: Spain vs India (1-3) - Board 4: Gukesh D vs Alexei Shirov
World Champion Gukesh defeated Alexei Shirov in 42 moves, exploiting dark-square weaknesses and a rook sacrifice that never yielded enough compensation.
Shirov chose the Sicilian Taimanov, but Gukesh seized the initiative in the middlegame. The key moment came on move 33 when Shirov played 33...Rd8, an inaccuracy; 33...Re8 was better. Gukesh then traded rooks with 34.Rxd8 and after 34...Qxd8, he continued with 35.Qg3, maintaining a winning position.
Gukesh's clean victory sealed India's 3-1 win over Spain.
Women's Section: Mongolia vs India (1-3) - Board 1: Mungunzul Bat-Erdene vs Koneru Humpy
Koneru Humpy was clearly winning at one point but a mistake allowed Mungunzul Bat-Erdene to equalize, and the game ended in a draw after 82 moves.
The Queen's Gambit Declined: Barmen Variation saw Humpy build a strong position, but on move 35 she played 35...f5, a mistake; 35...Rb3 was better. That allowed White to equalize. Later, Bat-Erdene erred with 47.Bxb6, where 47.g4 was stronger, but Humpy could not convert and the game was drawn.
Humpy's experience showed in the endgame as she held the draw.
Women's Section: Mongolia vs India (1-3) - Board 2: Vaishali Rameshbabu vs Munkhzul Turmunkh
Vaishali Rameshbabu drew with Munkhzul Turmunkh in a Petrov's Defense after 74 moves. Vaishali had minor chances but Turmunkh defended well.
The game was balanced throughout. Vaishali played 18.Rf5, though the engine preferred 18.Qf1. The position simplified into an endgame where neither side could make progress, and the draw was agreed.
The draw was a solid result for India.
Women's Section: Mongolia vs India (1-3) - Board 3: Bayasgalan Khishigbaatar vs Divya Deshmukh
Divya Deshmukh won with the black pieces against Bayasgalan Khishigbaatar in 47 moves, dominating with the bishop pair after a key mistake by her opponent.
The Catalan Opening: Open Defense saw Divya gain a strong position. The turning point came on move 35 when Bayasgalan played 35.Nb1, a mistake; 35.Bb5 was better. Divya capitalized with 35...Bd1+ and went on to win the endgame.
Divya's win gave India a crucial lead in the women's match.
Women's Section: Mongolia vs India (1-3) - Board 4: Savitha Shri B vs Munguntuul Batkhuyag
Savitha Shri B continued her perfect Olympiad with a fourth consecutive win, defeating Munguntuul Batkhuyag in a sharp attacking game that saw several blunders from both sides.
In the Sicilian Taimanov, Savitha built a strong attack. Batkhuyag erred with 32...Re6 (better 32...Qd7) and then blundered with 36...Kh8, where 36...Qc8 was necessary. Savitha missed a stronger continuation with 40.Nf6+ (better 40.Qf5+), but Batkhuyag blundered again with 42...Qc8, and Savitha sealed the win after 44.Qxc8.
Savitha's victory completed India's 3-1 win over Mongolia.
