IMOlivier-Kenta Chiku-Ratte

Olivier-Kenta Chiku-Ratté learned chess at eight at Montreal's École Saint-Joseph, where the game formed part of his mathematics lessons. His father, Benoit, was his first teacher at home. Lefong Hua began coaching him a year later and became a longstanding guide to his development. Chiku-Ratté gained experience in the Chess'n Math youth circuit and represented Quebec in the Canadian Chess Challenge. At the 2015 Quebec Open, he scored 6½/9, drew three grandmasters and achieved his first international-master norm. He completed his final norm at the 2019 US Masters in North Carolina while studying at university in Montreal. His later tournament successes include a perfect five-game victory at the 2026 Chambly championship.
