Who was Bobby Fischer?
Bobby Fischer learned chess from a booklet at age 6 and became US Champion at 14, the youngest in history. His 1972 World Championship match against Boris Spassky in Reykjavik was watched by millions worldwide and became the defining chess event of the Cold War era. Between 1970 and 1972 his rating performance was statistically the most dominant in chess history — he won two Candidates matches by perfect 6-0 scores. He forfeited his title in 1975 rather than play under conditions he found unacceptable and disappeared from competitive chess, resurfacing only for a 1992 rematch against Spassky.
How our Bobby engine plays
Our Bobby personality is built from a 13-stage analysis pipeline applied to historical game databases. Move selection runs through 12 style-scoring layers trained on Bobby's characteristic decisions — opening repertoire, strategic plans, causal chains between themes, and the kind of positions Bobby 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 Bobby's historical tendencies, constrained by safety filters that prevent blundering. The result is a bot that plays like Bobby, not just a strong engine wearing his name.
