    Stockfish Finds the Lines You Keep Missing

    Stockfish scores your games in your browser: the first 10 moves of every game, then 20, then whole games. Spaced repetition over your history finds where you keep making the same mistake.

  3. Step 3

    Replay Them and Beat Your Old Move

    Rematchess replays one of your games through that position, your opponent's moves playing themselves. A move you've never played there is set against the one you did: better wins, about the same ties, worse fails. A mistake always fails.

Play the move you meant to play.
