What you can do
The example opens a precomputed public game at one explained mistake. Use the normal move list, on-board annotations, captions, and Compare button. Drag a piece with “Explain moves I try” enabled to get a fresh explanation from Stockfish on your device.
The review opens without waiting for a full game analysis. Live engine evaluation and explanations of moves you try still take computation time.
