IMQuoc Hy Nguyen

Nguyễn Quốc Hy began learning chess at about six, first attending Smartchess and then training at the Tân Bình sports centre in Ho Chi Minh City. In 2015 his parents brought him back to Smartchess to study with grandmaster Từ Hoàng Thông. His coach valued his creativity and determination, recalling how disappointed the nine-year-old was to finish twelfth at the 2015 world youth championship. The following year, Quốc Hy won the world under-10 silver medal in Georgia, with seven wins, three draws and one defeat. He took silver in the classical section of the 2025 Southeast Asian Championship, recovering from an opening-round loss and beating eventual winner Raahul V S in the final round. At the 2026 Olympiad he earned his first grandmaster norm, with victories over grandmasters including Stamatis Kourkoulos-Arditis and Frode Urkedal. In the last round, his win over Aldiyar Ansat helped Vietnam draw with Kazakhstan and secure the team prize for rating Group B.
