He first met the game on long winter watches with his father, playing by lantern light while the sea hammered the rocks below, but the board has always been a quiet companion rather than a study. He has never opened a theory book, plays only a handful of games a year, and at an estimated 955 ELO he sits firmly in the improving-beginner bracket: he can spot a simple one-move tactic, yet pieces still drift off in messy positions and he has no settled repertoire. Opponents can expect a calm, unhurried game with long pauses between moves, the occasional sharp glance at a threat, and the kind of mistakes that come from instinct rather than preparation.","54","kerma","France","fr","c1a40dcbdccdc2e98e046f38e9598a2788e84e3285a9b1bdd269b6efb24b967d","2026-07-06",955,"json",[15,18,21],{"question":16,"answer":17},"What rating is Yann?","Yann is rated approximately 955 ELO, placing him in the improving-beginner range.
