Why chess.rodeo.

for game analysis
[01]

Free game analysis

We review imported games with Stockfish — clear move grades with a focus on the key mistakes. No subscription, no limits.

free · unlimited
[02]

Deep server-side analysis

Stockfish runs on our servers — not in your browser. No lag, no battery drain, no fan noise.

depth ≥ 22 · cloud
[03]

Detailed move classification

Every move is labelled: brilliant, great, best, good, inaccuracy, mistake, miss, blunder. Eight registers instead of "+0.4 / −1.1".

8 categories
[04]

Game Insights

Not "here are your 17 mistakes" but "here are the four patterns that keep repeating". Blind spots, recurring blunders, systematic tempo loss.

[05]

Accuracy rating

Accuracy by the lichess formula, computed for both players. Comparable to any standard analysis, no secret scale of our own.

Opening detection

Automatically recognises the opening from a 3000+ ECO variation database. From move one you see which theory you hit — and where you left it.

Frequently asked

01

Is chess.rodeo really free?

Yes. Game analysis is free — import from Chess.com, Lichess or upload PGN files and get a Stockfish review with no daily limits. Pro unlocks advanced extras: auto-import, learning moments, opening mistakes and a repertoire explorer.

02

Which chess engine do you use?

Stockfish 18 — the strongest open-source chess engine in the world. Analysis runs on our servers at depth 15+, and many positions are pre-analysed at depth 20+ from the Lichess database for instant results.

03

How is accuracy calculated?

We use the same formula as Lichess. The centipawn loss of each move is converted into a win probability, then averaged across every move. The result is a percentage reflecting how close your moves are to the engine's best lines.

04

Can I analyse games from any platform?

Directly from Chess.com and Lichess by username. For other platforms, export your games as PGN files and upload them here. We support multi-game PGN files.

05

How do Game Insights work?

Insights analyse the games you've already reviewed and find patterns in your play. The free tier uses your stored analyses; Pro can automatically fill in missing deep analysis and unlocks learning moments, opening mistakes and the repertoire explorer.

06

Is there a Chrome extension?

Yes. Install our extension to analyse games straight from Chess.com in one click. After a game ends you'll see an "Analyze on chess.rodeo" button that imports and reviews the game automatically.
