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 Indian Defense: Averbakh Variation: Moves, Plans & Analysis

The position

What Queen's Indian Defense: Averbakh Variation puts on the board

Material is level, with black to move.

No pawn occupies d4, e4, d5 or e5, so the central pawn structure is still fluid.

White has castled kingside; Black has castled kingside.

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

White’s plan

What White is trying to build

Claim central space without letting the long diagonals become weak.

Complete development before expanding on the queenside.

Black’s plan

How Black challenges it

Control e4 with pieces and pressure the centre from the flanks.

Use the b7 bishop and …c5 or …d5 to challenge White’s setup.

The idea

The tactical pattern to recognise

The b7 bishop can become powerful when the long diagonal opens.

Control of e4 determines whether White can build a full centre.

The mistake

What to check before committing

Blocking a fianchettoed bishop with an unnecessary pawn move.

Taking central space that cannot be maintained.
