Chess Analysis Tool (Stockfish 17.1)

Built by Jeff Gilbert

Analyze chess positions with Stockfish 17.1. Load a FEN position, set the analysis depth, and get detailed evaluations, best moves, and coaching notes. The tool will analyze the position and provide insights on the current state of the game.

Paste PGN and set seconds per move

ACPL uses this per-move time β€” higher = slower but more accurate.

Have a FEN instead of a PGN? Analyze the position at FEN Analysis.
