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.

Sicilian Defense: Morphy Gambit: Moves, Plans & Analysis

The position

What Sicilian Defense: Morphy Gambit puts on the board

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

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

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

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

White’s plan

What White is trying to build

Use the lead in development before Black’s queenside structure becomes active.

Choose a clear setup: an open d-file after d4, or a slower closed kingside expansion.

Black’s plan

How Black challenges it

Use the c-file and queenside pawn majority as active assets.

Finish development before starting pawn play on the wing.

The idea

The tactical pattern to recognise

A rook or queen on the half-open c-file can attack c2.

Central breaks with d4 or …d5 often change the position at once.

The mistake

What to check before committing

Launching a flank attack while pieces remain on their original squares.

Allowing a central break to arrive with tempo on the queen or king.
