Chess Olympiad: Thai IM pulls off upset win over Arjun

Thailand’s Prin Laohawirapap Stuns Arjun Erigaisi at Chess Olympiad

Indiadailyupdate.com – A remarkable individual result lit up the opening round of the Fide Chess Olympiad in Samarkand on Wednesday, as Thailand’s Prin Laohawirapap defeated Indian grandmaster Arjun Erigaisi despite a vast difference in their ratings.

Laohawirapap, 20, is Thailand’s only International Master and was rated almost 400 points below Erigaisi, who entered the event with a rating of 2759. India still secured the match 3-1, but the Thai player’s victory immediately became one of the standout stories of the tournament’s first day.

For Thai chess, the result carries particular significance. Beating a player of Erigaisi’s stature on the Olympiad stage is the kind of performance that can inspire younger players and remain a point of reference in national chess circles for years.

India’s board order draws attention

India’s Open team had already made an intriguing decision before the first moves were played. Reigning world champion Gukesh D was assigned to Board 4, while Nihal Sarin took Board 3, Erigaisi was listed on Board 2 and R Praggnanandhaa on Board 1.

With Praggnanandhaa resting for the opening round, Erigaisi moved up to the top board against Laohawirapap. The match arrangement placed one of India’s strongest players directly opposite Thailand’s leading International Master, creating a pairing that looked heavily tilted in India’s favour on paper.

Chess Olympiad team matches often create exactly these contrasts. Elite players are regularly matched against opponents from emerging chess nations, and the rating gap can be substantial. Yet the format also gives lower-rated players a rare chance to test themselves under the brightest competitive conditions.

Erigaisi had the white pieces and chose the Colle System. He held an advantageous position earlier in the game, but the contest gradually moved closer to drawing territory after 47.Nf3. A draw remained available, though his ambitious 50.Qg7 changed the direction of the game and allowed Laohawirapap to seize the opportunity.

“I’m super happy. It’s a really good moment for me.”

The upset also had an immediate ratings consequence for Erigaisi, who slipped out of the live top 10 following the defeat. Even so, India’s overall 3-1 victory ensured that the team opened its campaign with a successful result.

Indian women begin with a clean sweep

India’s women’s team, the top seed in its section, made an emphatic start by defeating the Dominican Republic 4-0. Koneru Humpy played on the leading board as India completed a full sweep in the opening round.

Divya Deshmukh did not play in the first match. The result nevertheless underlined the depth available to the Indian side, which began the Olympiad with all four points from its first team encounter.

In a tournament built around collective results, a strong opening round can establish momentum. Team standings are determined by match outcomes rather than the individual board score alone, making every pairing important across the long competition.

Olympiad produces drama beyond the boards

The opening day also brought difficult circumstances for several participating teams. Pakistan did not appear for its scheduled match against Israel, resulting in a walkover for Israel.

Namibia, meanwhile, faced player availability concerns after visa applications for two members of its team were rejected. Such logistical setbacks can have an outsized impact at the Olympiad, where squads depend on having enough players available to cover all boards and maintain options through the event.

Alongside the high-profile upset involving Erigaisi, another individual result illustrated the range of competition gathered in Samarkand. Iraq’s Ali Ehsan Aryan, rated 2163, held former world No. 2 Levon Aronian of the United States to a draw.

The United States won that tie 3.5-0.5, but Aryan’s half-point was a memorable personal achievement against one of the game’s most accomplished players.

“It was obvious we’ll lose, but it was a contest between us about who will last longer.”

That perspective captures much of what makes the Chess Olympiad distinctive. The event brings leading grandmasters and world champions into the same competition as players representing countries with far smaller chess infrastructures. Ratings offer a useful guide, but they do not decide a game once the clocks begin.

Laohawirapap’s win over Erigaisi was a vivid reminder of that reality. India emerged with the better team result, while Thailand gained a landmark individual victory. Both outcomes matter in an Olympiad setting, where national ambitions, personal breakthroughs and unexpected moments often unfold side by side.
