Defending a title is harder than winning it the first time, and India learned that lesson within a single afternoon in Samarkand. Three boards went exactly as the rating gap promised. The fourth produced the shock of the round - and left the defending champions sweating through what should have been the most comfortable match of their campaign.
India arrived in Samarkand as the team to beat, having swept both the Open and Women's gold medals in Budapest two years ago - a first in the country's chess history. No nation has defended the Open Olympiad crown since Armenia's back-to-back triumphs in 2006 and 2008, and that piece of history hovered over everything India did in round 1.
Against a Thailand team rated well below them on every board, India won 3-1. Gukesh Dommaraju, Nihal Sarin, and Vidit Gujrathi all converted with the professionalism you would expect. But Arjun Erigaisi, India's top board, was stunned by 2363-rated Prin Laohawirapap in a wild, error-strewn game that will be replayed long after this match is forgotten.
Board 1: Erigaisi Arjun vs Laohawirapap Prin - The Upset
This is the game the round will be remembered for. Erigaisi, rated nearly 400 points above his opponent, played a solid Colle-style setup and looked comfortably better for a long stretch of the middlegame. Then the position descended into one of the most chaotic sequences of the entire round - and it was the Thai teenager who kept his nerve when it mattered.
For eighteen moves this game went exactly the way a 2759 is supposed to handle a 2363. Erigaisi built a promising position, advanced his f-pawn all the way to f6 after Black failed to challenge it, and stood clearly better. What followed was one of the strangest sequences of the round: both players traded serious errors around moves 23-28, and instead of consolidating, White's coordination fell apart piece by piece while Black's kept improving.
The true turning point came on move 47, when Erigaisi's knight retreat threw away the last of his chances. Laohawirapap's queen and rook then hunted the white king with total precision, and the final blunder on move 50 allowed a forced mate. A 2363 beating a 2759 with this kind of composure is exactly what the Olympiad is for.
Board 2: Kulpruethanon Thanadon vs Nihal Sarin
Nihal's game had the cleanest arc of the four - a White setup that slowly overreached until one greedy pawn grab handed Black a winning position in a single move.
The entire game turned on that one greedy decision. After 22.Qxe7, Nihal's knight jumped to e5 with an attack on the queen, and from there Black's rook swung across the board collecting pawns while White's king had no shelter. Kulpruethanon resigned shortly after - a clean, controlled win for Nihal on board 2.
Board 3: Gukesh Dommaraju vs Alriyami Faris Rashid
For most of its length, this looked like a textbook demonstration of how an elite player squeezes a slightly weaker opponent in a balanced position. Gukesh never held a huge advantage early - what he had was patience, and it paid off devastatingly once his opponent's clock and nerve ran low.
From there, Gukesh was merciless. His kingside pawns marched forward, his pieces poured through the lines around the black king, and the second mistake - 30...Rg8 instead of capturing on e4 - removed the last hope of resistance. The final position left Black facing forced mate, and Alriyami resigned on move 37.
Board 4: Khumnorkaew Tupfah vs Vidit Gujrathi
Vidit's opponent made the brave decision to castle queenside against one of India's most experienced strategists. For a while it looked reasonable - then, in a single move, White handed Vidit exactly the kind of structural weakness a player of his caliber exploits without ever needing to force anything.
The whole game turned on that single positional decision. After 20.d5, White's dark-squared bishop had nothing left to do and Black's queenside pawns rolled forward unopposed. Vidit never needed to force the issue - he simply improved his pieces, opened lines for his rooks, and let White's structural problems do the work.
By the time White played 28.Rgg2 the position was already gone, but this move allowed a clean finish. Vidit's knight landed on e4 and then f2, forking queen and rook, and White resigned rather than play on a piece down in a hopeless position.
The Result
India closed out round 1 with a 3-1 victory and both match points. Gukesh, Nihal, and Vidit converted their games with the control you expect from the defending champions, while Erigaisi's board-1 defeat to Laohawirapap stood out as the day's genuine shock - for India and for the tournament. Eleven rounds is a long event, and round 1 delivered its reminder early: even the strongest team in the draw is one bad afternoon away from a headline it did not want.
