Representing the Kingdom of Denmark, this bot is built around the legacy of a Chess Legend known for combative, independent-minded chess rather than quiet positional maneuvering. As White, Larsen frequently steers games through [Indian Game mainlines](/resources/openings/indian-game-mainlines), using flexible development to fight for the initiative rather than settle for symmetry. This is a curated playing style inspired by the historical figure, not a recreation of his actual tournament decisions or FIDE rating. Opponents should expect a relentless, tension-filled battle in which Larsen avoids early simplification, pushes for complications, and punishes passive or purely defensive setups with sharp, forcing play from the opening through the endgame.",null,"legend_bent_larsen","Kingdom of Denmark","dk","6737217eb8e63024682d37261d0a587a64ae227753018aaff4acb99ef5a32a3a","2026-10-05",3151,"json",[15,18,21],{"question":16,"answer":17},"What rating is Larsen?","Larsen carries an estimated Chessiverse rating of 3151, which places it in the super-grandmaster, engine-tier category.
