Engines tell you a move was bad. Chess X-Ray tells you which bad moves you keep repeating. It reads your chess.com or Lichess games, finds the opening positions where you keep making the same costly move, and turns them into a course built from your own games: what you play, what to play instead, and why. Every line is checked by Stockfish. No generic puzzles, no 2,000-move repertoire to memorize. Just your 10 most expensive habits.
