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.

Ruy Lopez: Berlin Defense, Beverwijk Variation: Moves, Plans & Analysis

The position

What Ruy Lopez: Berlin Defense, Beverwijk Variation puts on the board

Material is level, with white to move.

White has central pawns on e4; Black has central pawns on e5.

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

White’s plan

What White is trying to build

Maintain central tension and prepare d4 with pieces behind it.

Use the c3–d4 structure or queenside manoeuvres rather than rushing the bishop exchange.

Black’s plan

How Black challenges it

Challenge White’s centre and find useful squares for the queenside pieces.

Decide whether the a6–b5 expansion gains space without loosening the queenside.

The idea

The tactical pattern to recognise

Pressure on e5 is often indirect because the e4 pawn can also be attacked.

A bishop capture on c6 can alter the pawn structure and the d5 square.

The mistake

What to check before committing

Assuming Bxc6 wins the e5 pawn without checking the tactical reply.

Moving the same queenside pieces repeatedly while the king remains uncastled.
