Analyze my chess games: one game, or all of them at once

By Chess Goat · Updated November 2, 2026

There are three ways to analyze your chess.com games here, and two of them are free: your habits across up to 1,000 games, a Stockfish review of any single game, and a deep report on up to 2,000 games.

Which analysis do you need?

Analyze your habits in five seconds

Your Goat Card reads the clocks and results of up to 1,000 of your recent bullet, blitz and rapid games on chess.com. It doesn’t need an engine for this: the numbers that decide most games below master level are in the clock and the result. It shows how you score right after a loss, what happens when your clock gets low, your best and worst hours, the rivals you meet most, and one stop-loss rule that would have saved you rating points. Type a username and it’s there in about five seconds.

Analyze one game with Stockfish

Your recent games are listed on the same card. Open one and Stockfish 19 reviews every move in your browser: accuracy for both players, each inaccuracy, mistake and blunder, and the best move where you went wrong. There is no daily limit, unlike the one free review a day on chess.com (how the chess.com limit works). For a game from anywhere else, Lichess or over the board, paste its PGN into the game review. The card’s Find my worst blunder button checks your last 10 games at once. On a laptop, the free Chrome extension puts the same review on chess.com itself: a review button on every finished game.

Analyze all your games at once

One review shows you the blunder. A few hundred show you the habit behind it: the same loose piece, the same thrown-away winning position, the same opening hole. The Goat Report runs Stockfish on up to 2,000 of your games, sorts every big mistake into six leaks, ranks them by the rating points each one costs you beyond what your opponents lose to the same thing, and turns the worst into puzzles from your own games and an 8-week plan. It arrives by email in about 1.5 hours.

Prefer to do it yourself? Open your games one at a time in the free review, write down the first move where the evaluation dropped, and tally what kind of mistake it was. After 20 or 30 games the pattern is usually obvious. Accuracy uses the lichess formula, the same one the Goat Report uses.

Then fix what you found

Hanging pieces: the blunder check. Losing after losses: a stop-loss rule. Low on time: a clock budget. Or start the lesson course, which puts the lessons for your biggest leaks first.

Want every move of up to 2,000 games checked, and the mistakes you repeat ranked? The Goat Report is $5, paid once. See a blitz sample and a rapid sample first.
