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.

Queen's Gambit Declined: Been-Koomen Variation: Moves, Plans & Analysis

The position

What Queen's Gambit Declined: Been-Koomen Variation puts on the board

Material is level, with white to move.

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

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

White’s plan

What White is trying to build

Build pressure on the centre and recover or use the c-pawn investment through development.

Place rooks on the c- and d-files once the centre is clarified.

Black’s plan

How Black challenges it

Challenge d4 with …c5 or …e5 when development permits.

Complete development without trying to hold c4 at any cost.

The idea

The tactical pattern to recognise

The isolated queen’s pawn can be both a weakness and a source of active play.

Minor-piece pressure on c6, d5 and e4 often decides the central break.

The mistake

What to check before committing

Trying to win the gambit pawn while the king remains in the centre.

Trading into a passive structure without contesting an open file.
