Adolf Anderssen

Biography

Adolf Anderssen was a mathematics teacher who became the undisputed king of chess in the 1850s. He won the first international chess tournament in London in 1851 and is best remembered for two games: the 'Immortal Game' (1851), in which he sacrificed both rooks and his queen to deliver checkmate, and the 'Evergreen Game' (1852), another brilliant queen sacrifice. He was defeated by the young Morphy in 1858 but remained among the world's best players for another decade. His games represent the pinnacle of Romantic chess — daring, brilliant, and beautiful.

Strongest player of the 1850s-60s. Played the Immortal Game and the Evergreen Game.

How our Adolf engine plays

Our Adolf personality is built from a 13-stage analysis pipeline applied to historical game databases. Move selection runs through 12 style-scoring layers trained on Adolf's characteristic decisions — opening repertoire, strategic plans, causal chains between themes, and the kind of positions Adolf actually steered toward in real games.

The underlying search engine is a 2630-Elo UCI engine, but its top candidate is not automatically played: the style layer picks the move most consistent with Adolf's historical tendencies, constrained by safety filters that prevent blundering. The result is a bot that plays like Adolf, not just a strong engine wearing his name.
