TatamiChess trains you against the chess you actually face
TatamiChess analyzes chess.com or Lichess games, identifies costly openings, and turns them into rating-specific drills and boss games.
Field notes
TatamiChess organizes opening study around a player's own game history rather than a fixed master repertoire. The homepage shows a sample covering 214 games across six months, with openings ranked by apparent cost and replies grouped by opponent rating bands. Training proceeds through Build, Drill, and Boss stages, while merit, seals, kyū-to-Dan grades, and opening belts provide a visible progression system. The page cites chess.com, Lichess, Lichess Explorer, and Stockfish.
