Hello, and welcome to the board. I am Larsen from Denmark. Take a seat, pick your colour, and let us see whether you can handle a game where the pieces stay busy and the tension never quite goes away. Good luck, and enjoy the fight.
Bent Larsen is a Chessiverse bot and a free, independent historical simulation inspired by the Danish chess legend of the same name. The bot represents the Kingdom of Denmark and carries an estimated Chessiverse rating of 3151, which is super-grandmaster, engine-tier strength: it beats nearly all human masters and plays close to theoretically perfect chess. That rating describes the bot's curated style on this site. It is separate from the historical player's actual decisions and FIDE rating, and the bot is not endorsed by the player or his estate. No Premium subscription is required to play it. Its repertoire on file includes the Nimzo-Indian as Black, along with the Accelerated Dragon, the Indian Game mainlines and the open Sicilian as White, each backed by dozens or hundreds of games. Those choices reflect a taste for active piece play and unbalanced positions over quiet equality. Opponents should expect an aggressive player that keeps tension on the board, avoids easy simplification, and punishes inaccuracies with near-flawless calculation.
How Larsen plays
Larsen plays aggressively and prefers to keep tension rather than trade down, so pieces stay on the board and positions stay complicated. The sharpness is only slightly above neutral, and the bot leans toward offbeat choices over strict mainline theory. As White it uses the Sicilian Defense: Open and Indian Game setups, and as Black it turns to the Nimzo-Indian and Accelerated Dragon.
Who should play Larsen
Strong masters and titled players rated roughly 2400 and above are the natural audience, since the bot's 3151 rating makes it a demanding benchmark. Ambitious experts below that band can also learn from the matchup. Players who want to practice defending against a sustained initiative, handling unresolved tension, and calculating accurately in complicated middlegames will find the games especially instructive, as simplifying rarely offers relief.
