SAMARKAND, Uzbekistan — The FIDE Chess Olympiad is often defined by its unpredictability, but rarely does the opening day deliver a shockwave quite as profound as the one that reverberated through the tournament hall on Wednesday. In a stunning turn of events that has sent ripples across the international chess community, India’s second-ranked star, Arjun Erigaisi, suffered a monumental upset at the hands of Thailand’s Prin Laohawirapap in the first round of the 2026 Olympiad.
With India’s top board player, R. Praggnanandhaa, rested for the opening match, the responsibility of leading the team fell to the 23-year-old Telangana grandmaster. Entering the fray with a formidable Elo rating of 2759, Erigaisi was the overwhelming favorite against Laohawirapap, an International Master rated 2363. On paper, the 400-point rating chasm suggested a routine victory for the white pieces. Instead, fans and analysts alike witnessed one of the most significant upsets in recent Olympiad history, with Chess.com even designating the Thai IM’s performance as the “Game of the Day.”
How the Grandmaster Lost the Plot
Veteran Grandmaster Pravin Thipsay, providing expert analysis on the collapse, noted that Erigaisi initially appeared comfortable. “The Indian grandmaster started with the Colle system, which, while not the sharpest choice, provided him with a slight, stable advantage,” Thipsay remarked.
The trajectory of the game shifted on move 18. According to Thipsay, the Thai player miscalculated by opting for Rook e8 instead of taking on f5, a move that would have maintained parity. Following that error, Erigaisi surged into a powerful, seemingly winning position, backed by a significant time advantage on the clock.
However, the tide turned on move 28. “Instead of launching a pawn roller with h4, Arjun chose to trade the black knight that had infiltrated his territory,” Thipsay explained. “The move Bxd3 was a lapse that neutralized his advantage and leveled the board.”
The roller-coaster nature of the game continued when the Thai player committed his own serious error on move 31. By weakening his kingside, Laohawirapap handed the initiative back to the Indian GM. What followed was a masterclass in resilience from the lower-rated player, who managed to complicate the position by offering an exchange—rook for knight—on moves 46 and 47.
“By taking the rook with his knight on e4, Arjun could have secured a win, even with an exposed king,” Thipsay noted. “Instead, he played knight f3, which steered the game toward a drawish conclusion.”
The final undoing was a byproduct of ambition. In a position that was firmly set for a draw, Erigaisi played 50. Qg7, a move intended to force checkmate. The aggressive maneuver backfired spectacularly, allowing the Thai IM to execute a simple tactical sequence that led to an immediate checkmate of the Indian star. “Quite an unexpected result,” Thipsay concluded. “A great setback for Arjun, considering the massive rating disparity.”
Team Resilience: India Bounces Back
Despite the individual trauma suffered on Board 1, the collective strength of the Indian contingent proved more than sufficient to absorb the blow. The loss did not derail India’s momentum in the team standings, as the depth of the squad stepped up to secure a comfortable 3–1 overall victory.
Gukesh, Nihal Sarin, and Vidit Gujrathi each notched clinical victories against their Thai counterparts, ensuring that the team’s opening campaign got off to a winning start. The collective poise of the squad underlines why India remains a favorite to contend for the podium in Samarkand.
On the women’s side, the Indian team demonstrated total dominance. Even with top player Divya Deshmukh given a rest day, the squad dismantled the Dominican Republic with a perfect 4–0 scoreline. This performance placed India firmly among the nine top-seeded teams that recorded clean sweeps on the opening day of the Women’s Olympiad. Germany remains the only top-10 seed that showed any vulnerability, narrowly edging out Malta 3–1.
As the tournament progresses, all eyes will be on how Arjun Erigaisi responds to the early adversity. India, the defending champions in both the Open and Women’s categories, continues its journey on Thursday. The men’s team is slated to face Indonesia, while the women’s team prepares to square off against Finland. In a tournament where every half-point is vital, the resilience of the Indian squad will be tested as they look to maintain their quest for gold.
