Why isn't Chess.com Game Review explaining my moves?

If Chess.com's Game Review labels your moves Mistake or Blunder but doesn't say why, it's usually your plan, not a bug. Chess.com's Help Center lists Coach explanations on all of your moves as a Diamond feature (checked October 22, 2026). The other plans get accuracy and move classifications, which tell you that a move was worse, not why.

What Chess.com Game Review shows on each plan

(updated October 20, 2026), all on Chess.com's Help Center. The daily limits are covered in detail in how many free game reviews Chess.com gives you.

On Diamond and still no explanation? Check the review settings: gear icon, then Interface, then Review. "Show Coach Avatar" only hides the avatar; the feedback stays. "Show Arrows" chooses Best Move arrows, Coach visualizations, both or neither. If the Coach has gone quiet, the speaker icon in the top-right corner mutes and unmutes the audio.

Chess.com Game Review vs Coach explanations

These are two layers, and people often mix them up.

• Game Review is the verdict. Each move gets a classification: Brilliant, Great, Best, Excellent, Good, Book, Inaccuracy, Mistake, Miss or Blunder. The game gets an accuracy score from 0 to 100.
• Coach explanations are the reasons. They put the verdict into words: what your move did and what you missed.

Accuracy is not your rating, either. Chess.com's own help article says accuracy measures how closely you matched the engine's preferred moves and shouldn't be read as an overall measure of your strength.

Why engine labels alone don't teach a beginner

• A label is a verdict, not a reason. "Mistake" means the engine's evaluation went down. It doesn't say whether you missed a fork (one piece attacking two at once), left a piece undefended or let a threat through.
• The better move can look random. An engine line is a list of moves, not an idea. If you can't name the idea, you can't reuse it in your next game.
• The engine doesn't know what was hard. Lichess's accuracy page makes this point: Stockfish can judge whether a move is sound, but not how difficult it was to find. The same page says centipawns (hundredths of a pawn, the engine's unit) work well for building engines and much less well for human understanding.
• Labels move around. Chess.com notes that the quick summary after a game uses a faster analysis than the full review, so a move can be relabelled. Lichess adds that there's no universally accepted way to compute accuracy, so two sites can score the same game differently.

That's why "chess.com game review doesn't make sense" is such a common search. The review isn't wrong. It's written for someone who already sees the idea behind the move.

An example: the knight move that attacked the queen

r . . q . r k .
p . p b p p b p
. . . p . . p .
. . . P . . . .
P N . . n . . .

Black to move. White's queen is attacking the black knight in the centre, and nothing defends that knight, so it has to move. Two squares look natural.

Knight to c5 (red arrow) attacks the queen. It feels strong, but a queen is easy to save: it simply steps away. The engine's reply is the queen to c4, which attacks the knight right back, and Stockfish rates the position as about equal.

Knight to c3 (green arrow) attacks the rook instead. The knight is safe there, because the bishop on g7 guards that square along the long diagonal. If the queen takes the knight, the bishop takes the queen. So the rook has to move, the knight stays on its strong square, and Black's next idea in the engine's lines is to go after White's other knight, which has no defender. Stockfish rates this as clearly better for Black: about −1.8, against about −0.3 after knight to c5. (Minus means Black is better.)

An engine review tells you that knight to c3 was better. The explanation is what you take into your next game: before you attack the biggest piece, ask whether your opponent can answer easily. A queen that just steps away, with an attack of its own, gains you nothing. A rook attacked by a protected knight has to move while your knight stays put.

How to get explanations of your moves

1. Read the engine line one move at a time. For each move ask three questions: what does it attack, what does it defend, what does it leave unprotected?
2. Use the buttons Chess.com already gives you. On key moves, the Coach's speech bubble offers options such as Show Fork, Show Lost Piece and Show Idea. Retry lets you find the better move yourself before you see it.
3. Ask "why" about your move, not only the best one. What did your move allow that the better move prevents? That's usually the lesson.
4. Use a tool that explains in words. On Chess.com that's Diamond's Coach explanations. Chess It Up says its free reports include coach explanations for key moves (its own site, October 2026). Chess Coach does it inside Claude, as below.

How Chess Coach explains moves

Chess Coach is a connector for Claude that reviews your finished Chess.com and Lichess games. Stockfish runs on our server and picks out the two or three key moments. Every evaluation comes from the engine, and each move is described from the rules of chess: what it attacks and what it leaves undefended. Claude turns those facts into plain words.

On the board, the red arrow is the move you played and the green arrow is the better one. The "Why?" buttons send your question about the position on screen straight to Claude, and you can ask about any other move too, for example "Why was my bishop move on move 15 a mistake?". Explanations can be set to beginner, intermediate or advanced. The free plan includes one in-depth review per day.
