Thinking…

This board runs Stockfish directly in your browser, the same engine used to grade games elsewhere on this site, so every evaluation you see here is computed on your own device rather than a shared server queue. Play out any line by dragging pieces, or paste a FEN (a single-line position code) or a full PGN (a game's move list) to jump straight to a specific spot.

The evaluation bar and number are always from White's perspective — positive means White is better, negative means Black is better, in pawns. Below the board, the engine's own recommended continuation shows what it considers the best line from the current position, updated live as you move pieces or step through the move list.
