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.

Center Game: Paulsen Attack Variation: Moves, Plans & Analysis

The position

What Center Game: Paulsen Attack Variation puts on the board

Material is level, with black to move.

White has central pawns on e4.

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

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

White’s plan

What White is trying to build

Develop around the Center Game pawn structure before starting a wing operation.

Keep the central pawn breaks available until the pieces show which one helps.

Black’s plan

How Black challenges it

Contest the centre and finish king safety before collecting loose material.

Meet the named attack with development and a counterstrike in the centre.

The idea

The tactical pattern to recognise

Central pawn breaks can open files while a king or queen is still exposed.

Loose pieces and undefended central pawns matter more when both sides are still developing.

The mistake

What to check before committing

Repeating a piece move without checking whether a new piece can be developed instead.

Starting a flank plan while the centre can still open against the king.
