Seventeen-year-old Ukrainian international master Roman Dehtiarov claimed victory at the 2026 European Individual Chess Championship in Katowice, Poland, becoming the youngest and lowest-seeded winner in the event's history. Seeded 126th out of 501 players, he scored 9 out of 11 to finish sole first. The triumph earned him the grandmaster title, €20,000 in prize money, and a spot in the 2027 FIDE World Cup.
The tournament, held from April 7 to 19, featured an 11-round Swiss-system format with a time control of 90 minutes for the first 40 moves plus 30 additional minutes and a 30-second increment per move. Dehtiarov, from Kharkiv near the Russian border, overcame significant challenges, including limited travel and practice opportunities amid the war in Ukraine since 2022. GM Pavel Eljanov recounted attempting to evacuate Dehtiarov's family when he was 14, but the young player chose to stay with his father. Despite a setback with an eighth-move loss to Turkish GM Isik Can in round five, Dehtiarov rebounded with 5.5 points from his next six games against strong grandmasters, including a key win over French GM Maxime Lagarde. In the final round, he defeated Spanish GM David Anton, who had led after eight rounds, securing the win amid several top-board draws focused on World Cup qualification spots. Dehtiarov also topped the junior category for players under 18. The women's section saw IM Teodora Injac take first on tiebreaks at 6.5 points, while 2004 champion GM Vasyl Ivanchuk won the senior category with 7.5 points in 26th place overall. This marks the first time an international master has won the title since its inception in 2000.
