- CAPS accuracy scoreMeasures your average centipawn loss per move and grades the game with clear, colour-coded bands.

- Piece heatmapReveals which pieces — pawn, knight, bishop, rook or queen — cost you the most points.
- Time-pressure breakdownCompares your accuracy at normal speed versus when the clock is low — so you know if you fall apart under pressure.
- Session badgesEarn Blunder Buster, Endgame Apprentice, Opening Scholar, Precision Master and more — progress tracking that's genuinely fun.
Why review your games
The fastest way to improve is to learn from your own games. Instead of guessing where things went wrong, Chess Nexus pinpoints your blunders, shows the better moves, reveals which pieces and which moments cost you, and tracks your accuracy over time — all free and ad-free.
Frequently asked questions
How can I analyse my chess game for free?
Open the analysis tool on Chess Nexus, load your game and get an instant move-by-move review — accuracy score, blunder detection, piece heatmap and more — completely free, with no ads.
What is a CAPS / accuracy score?
It's a single number that summarises how accurately you played a game, based on your average centipawn loss per move. A higher accuracy and lower loss means cleaner, more precise play.
Will analysis tell me where I went wrong?
Yes. The review flags every blunder, mistake and inaccuracy, shows the stronger move, highlights which pieces let you down and reveals whether time pressure hurt your accuracy.
