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.

Blackmar-Diemer Gambit Accepted: Gunderam Defense: Moves, Plans & Analysis

The position

What Blackmar-Diemer Gambit Accepted: Gunderam Defense puts on the board

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

White has central pawns on d4.

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

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

White’s plan

What White is trying to build

Develop around the Blackmar-Diemer Gambit Accepted pawn structure before starting a wing operation.

Use time and open lines as the compensation; recovering material is secondary.

Black’s plan

How Black challenges it

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

Improve the least active piece before committing the pawn structure.

The idea

The tactical pattern to recognise

Checks, forcing captures and development with tempo determine whether the offered material is justified.

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.

Accepting material without calculating the opponent’s forcing reply.
