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.

Semi-Slav Defense: Gunderam Gambit: Moves, Plans & Analysis

The position

What Semi-Slav Defense: Gunderam Gambit puts on the board

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

White has central pawns on d4; Black has central pawns on e4.

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 naturally while preserving pressure on d5.

Use cxd5 or e4 only when the resulting centre suits the pieces.

Black’s plan

How Black challenges it

Develop the light-squared bishop outside the pawn chain when the move order allows.

Prepare …c5 or …e5 to free the position.

The idea

The tactical pattern to recognise

The c4 pawn can be taken, but holding it may cost development.

Breaks on c5 and e5 determine whether Black’s position stays cramped.

The mistake

What to check before committing

Winning c4 and then spending too many tempi defending it.

Closing in the c8 bishop without a route back into the game.
