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.

Dutch Defense: Leningrad: Moves, Plans & Analysis

The position

What Dutch Defense: Leningrad puts on the board

Material is level, with white to move.

White has central pawns on d4.

White has castled kingside; Black can still castle either side.

White’s plan

What White is trying to build

Challenge the dark squares and open the centre before Black’s kingside pressure grows.

Use the e4 break when it can be supported.

Black’s plan

How Black challenges it

Use the f-pawn for kingside space while keeping e6 and the king secure.

Choose a coherent setup around …e6, …g6 or …d6.

The idea

The tactical pattern to recognise

The e6 and e5 dark squares can weaken after …f5.

Kingside attacking chances often come with exposure on the e8–h5 diagonal.

The mistake

What to check before committing

Pushing kingside pawns faster than pieces can join the attack.

Ignoring e4 and allowing White an ideal central expansion.
