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.

Grünfeld Defense: Flohr Defense: Moves, Plans & Analysis

The position

What Grünfeld Defense: Flohr Defense puts on the board

Material is level, with white to move.

White has central pawns on d4; Black has central pawns on d5.

White has castled kingside; Black has castled kingside.

White’s plan

What White is trying to build

Use the central pawn mass, but be ready to spend tempi defending it.

Develop pieces to support d4 and exploit the space advantage.

Black’s plan

How Black challenges it

Attack d4 with the g7 bishop, …c5 and active piece pressure.

Prefer activity against the centre over passive occupation of it.

The idea

The tactical pattern to recognise

The d4 pawn is repeatedly attacked along the long diagonal.

A timely …c5 or …e5 can dissolve White’s centre.

The mistake

What to check before committing

Advancing the centre beyond the pieces that support it.

Trading active pieces and leaving White an uncontested centre.
