How do I analyze a chess position online for free?

Set up the position on the board or paste its FEN, then run the analysis. You get the best move, an evaluation and alternatives with no account or download.

What is a FEN and where do I find one?

A FEN is a short text code describing every piece on the board. Most chess sites let you copy it from a game's menu or board editor, and you can paste it straight into NextMove.

What does the evaluation bar mean?

It shows which side is better. Positive favors White, negative favors Black, and larger numbers mean a bigger advantage.

Is NextMove really free?

Yes, with no subscription, login or limits.

Is it ethical to use this tool?

It's for study and post-game review only. Don't use it during live games against other people.
