Oslo: World No. 1 Magnus Carlsen secured a decisive victory over reigning classical world champion D Gukesh on Thursday, a result that relegated the young Indian grandmaster to the bottom of the tournament standings. Concurrently, R Praggnanandhaa maintained his hold on second place by defeating Vincent Keymer during an Armageddon tie-breaker at the Norway Chess tournament.

Carlsen, a seven-time champion of the event who had experienced an uncharacteristically sluggish opening to the competition, advanced from the bottom of the field into sole possession of fourth place. He accumulated three full points to bring his total to 4.5. Following the match, a visibly dejected Gukesh exited the playing venue through a side door, bypassing dozens of young enthusiasts who had assembled to request autographs.

The field enters Friday's scheduled rest day with Alireza Firouzja retaining the tournament lead despite absorbing his inaugural defeat of the competition, an Armageddon loss to Wesley So that followed a draw in their initial classical encounter. Firouzja secured a single point from the tie-break to reach a total of 8.5, preserving a 2.5-point advantage over Praggnanandhaa, who occupies second place with six points.

The United States' Wesley So holds third position with 5.5 points, sitting one point ahead of Carlsen, while Keymer possesses four points. Gukesh remains stationary at the bottom of the six-player Open field with 3.5 points, raising concerns of a difficult campaign ahead of his world championship title defence against Uzbek challenger Javokhir Sindarov later this calendar year.

The Open Division Dynamics

The encounter lacked the physical gestures or emotional exclamations that characterised Carlsen’s loss to Gukesh during the 2025 iteration of the tournament. Instead, the Norwegian grandmaster methodically converted a positional advantage while commanding the black pieces.

"I wouldn't say I was super-motivated today. I kind of had enough after playing really poorly for three days in a row with very little time. Today, I didn't have a lot of expectations, but I was happy with the way things went in the opening," Carlsen remarked following the conclusion of the round.

The five-time world champion noted that his opponent's opening strategy caught him off guard.

"I was surprised by Nf3. I wasn't sure if I couldn't take it, but it seemed like a draw at most. He sometimes plays a little too ambitiously, and I think he did that today as well. He wanted to prove a serious advantage, and I'm not sure there was one. Eventually, he played himself into some trouble, and I gradually took over," Carlsen stated.

Carlsen further disclosed that he experienced moments of late-game apprehension despite holding a commanding structural superiority on the board.

"Right at the end, I was a little worried (if) I was allowing him to take a knight with check. I was thinking, This happened against Praggnanandhaa yesterday, it happened against Gukesh last year -- am I actually missing something? But if I was, he didn't find it," the Norwegian added.

Gukesh, who reached his 20th birthday mere hours after the conclusion of the match, faces critical self-examination during the rest day prior to his fifth-round pairing against compatriot Praggnanandhaa. To date, Praggnanandhaa has demonstrated a highly resilient competitive temperament and an enhanced capacity to absorb the psychological pressures of the elite Norwegian event.

During their classical encounter, both Praggnanandhaa and Keymer failed to capitalise on distinct winning opportunities, culminating in a draw. However, the Indian grandmaster concluded the ensuing Armageddon tie-break effectively in 17 moves.

"The Armageddon went smooth," Praggnanandhaa noted after securing 1.5 points to fortify his second-place ranking.

The rapid format continues to present a persistent obstacle for Keymer, a tournament debutant who has now dropped four consecutive tie-breaking matches.

Women's Tournament Results

In the Norway Chess Women's division, Divya Deshmukh suffered her inaugural Armageddon setback of the competition, falling to defending champion Anna Muzychuk after previously winning three consecutive tie-breakers. The defeat displaced the World Cup champion from sole possession of second place into a three-way tie for third with 5.5 points.

Koneru Humpy’s competitive struggles persisted as she dropped an Armageddon match to Zhu Jiner, leaving her in last place within the six-player field.

Bibisara Assaubayeva heads the women's division with seven points, followed by Muzychuk, Deshmukh, and Zhu, who hold 5.5 points apiece. Reigning women's world champion Ju Wenjun possesses four points, while Humpy trails the field with three points.
