Van Foreest’s Historic Victory Over Carlsen
In a dramatic turnaround at the 2026 TePe Sigeman Chess Tournament in Malmö, Grandmaster Jorden van Foreest pulled off an extraordinary upset by defeating Magnus Carlsen in classical chess. This marks a historic achievement for the Dutch player, making him only the second person to overcome the world’s top-ranked player since Gukesh Dommaraju’s celebrated win at Norway Chess 2025.
The victory came under challenging circumstances. A fire alarm sounded at 1:30 a.m. at the tournament venue, forcing all players to evacuate their rooms. Van Foreest described the jarring experience, explaining that he had just fallen asleep when the loud alarm startled him awake in total disorientation. Despite returning to sleep by 2:30 a.m. and getting seven hours of rest before the match, the disruption added an unexpected element to an already challenging day.
A Grueling Battle in the Endgame
The game itself was characterized by intense psychological warfare and narrow margins. Van Foreest opted for a 6.f4 variation against Carlsen’s Najdorf defense, a choice that caught the world champion slightly off-guard and prompted an eight-minute pause for consideration. The Dutch grandmaster had strategically selected a line that Carlsen might not have fully prepared for.
Carlsen fought tenaciously throughout, managing to navigate toward what appeared to be a fortress position with a likely draw. However, Van Foreest refused to concede and found a critical breakthrough opportunity. The match descended into an extremely tight endgame where the position repeatedly swung between advantage for White and a drawn result.
In the final stages, Carlsen’s knight became trapped and the position became untenable. The world champion acknowledged defeat without the dramatic table reaction that followed his previous classical loss to Gukesh. Van Foreest reflected on the intensity of the encounter, noting: “I was already resigned to making a draw and I was OK with it, and then suddenly I got this moment out of nowhere and things spiraled out of control once again.”
Erdogmus Continues Meteoric Rise
While Van Foreest’s upset dominated the headlines, the 14-year-old sensation Yagiz Kaan Erdogmus delivered his own impressive performance. The young prodigy claimed sole tournament leadership by defeating Nils Grandelius with a brilliant attacking display. Erdogmus’s continued ascent through the world chess rankings has established him as an extraordinary talent, and his performances at Malmö confirm his status as one of the most remarkable prospects in the sport’s history.
Other Round 4 Results
The tournament’s fourth round featured compelling action across all boards. Grandmaster Zhu Jiner notched her first victory of the competition by exploiting an opening miscalculation from Andy Woodward. The only drawn game saw Nodirbek Abdusattorov fail to capitalize against Arjun Erigaisi, missing an opportunity to claim the top spot.
After Round 4, Erdogmus leads the standings alone, while Van Foreest, Abdusattorov, and Erigaisi share second place. The fifth round is scheduled for Tuesday, May 5, commencing at 9 a.m. ET / 3:00 p.m. CEST / 6:30 p.m. IST.
Looking Ahead
Van Foreest’s triumph represents a watershed moment in his career. Despite the disruptive circumstances of the evening, he managed to maintain focus and convert an advantage that even he initially thought might slip away. His victory serves as a reminder that even dominant players like Carlsen remain vulnerable to determined and well-prepared opponents.
