Yes. Game review is free, with no account and no limit on how many games you analyse.

I have used my free Chess.com Game Review for the day. What now?

Open the same game here instead. Type rv in front of chess.com in the game's address: chess.com/game/live/12345678 becomes rvchess.com/game/live/12345678, and a full review builds itself. There is no daily cap because the engine runs in your browser rather than on a server.

How do I review a Chess.com game?

Type rv in front of chess.com in a saved live, daily, or computer game link, paste the link into the import box, or look the game up by Chess.com username.

How do I review a Lichess game?

Paste the game link into the import box. Any Lichess address works: the plain lichess.org/abcd1234 form, the longer one your own games get, and the /white and /black variants.

Which engine does the analysis?

Stockfish 18, compiled to WebAssembly. Analysis stays inside your browser. Completed games are contributed only if you explicitly enable the de-identified research option.

Can I analyse a single position instead of a whole game?

Yes. Open the sandbox, set the position up by dragging pieces or pasting a FEN, and Stockfish evaluates it live as you play both sides, with the best moves drawn on the board.

Can I review a PGN without an account?

Yes. Paste the PGN into the import panel and the review starts on its own. No sign-in is required; game contribution is off by default.

Caro-Kann Defense: Panov-Botvinnik: Moves, Plans & Analysis

The position

What Caro-Kann Defense: Panov-Botvinnik puts on the board

Black has a one-pawn material edge; white is to move.

White has central pawns on d5.

White can still castle either side; Black can still castle either side.

The c-file is half-open for White, giving that side a natural pressure lane.

White’s plan

What White is trying to build

Use the space advantage to develop actively and decide whether e5 should be held or exchanged.

Watch the timing of c4 or f4 pawn breaks.

Black’s plan

How Black challenges it

Develop the light-squared bishop before closing it behind …e6.

Attack White’s centre with …c5 and complete kingside development.

The idea

The tactical pattern to recognise

Pressure against d4 after …c5.

A bishop developed to f5 can be chased, creating useful tempos or weaknesses.

The mistake

What to check before committing

Spending several moves hunting the f5 bishop without finishing development.

Playing passively after achieving a sound pawn structure.
