Who was Jan Timman?
Jan Timman was the best Western player during the era of Soviet chess dominance, a period when the world's top ten were almost exclusively from the USSR. He reached the Candidates Final in 1983 and was runner-up for the FIDE title in 1993. A prolific chess author, his books on endgames and attacking play are considered classics. His sharp, creative style — always willing to complicate and take risks — made his games some of the most entertaining of his generation. He passed away in 2025 and is remembered as one of the great ambassadors of Western chess.
How our Jan engine plays
Our Jan personality is built from a 13-stage analysis pipeline applied to historical game databases. Move selection runs through 12 style-scoring layers trained on Jan's characteristic decisions — opening repertoire, strategic plans, causal chains between themes, and the kind of positions Jan 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 Jan's historical tendencies, constrained by safety filters that prevent blundering. The result is a bot that plays like Jan, not just a strong engine wearing his name.
