How to review a game

  1. Open your Goat Card: type your chess.com username. No sign-up, no email.
  2. Scroll to your games. Your recent live games are listed newest first, 50 at a time, with the result, ratings and opening.
  3. Click a game. The board opens on the final position with the move list, and Stockfish starts reviewing every position. A whole game takes a few seconds.
  4. Step through the review: accuracy for you and your opponent, each inaccuracy, mistake and blunder marked on the board, and the engine’s best move where you went wrong. Click a mistake to jump to it.

The full review runs on a laptop or desktop: Stockfish runs on your own computer, so nothing waits in a queue and there is no limit. On a phone you can still replay every game, and the card’s Find my worst blunder button checks your last 10 games with the same engine.

Chess.com is still the best place to play, and its reviews come with explanations and a coach voice. If you just want to see where a game turned, and you don’t want to wait for tomorrow’s free review, this does it.

One game tells you what happened. Many games tell you why.

Reviewing games one at a time shows you the blunder. It rarely shows you the habit behind it: the same loose piece, the same clock collapse, the same opening hole, game after game. Your Goat Card already reads the patterns in your clocks and results for free. For the engine view across hundreds of games, the Goat Report ranks the mistakes you repeat by the rating points they cost.

Then fix them: a blunder check that sticks, or the lesson course, which starts from what your games show.
