Drag a piece or tap it to see its legal moves. You play both sides.
How it works: openings are recognised from a built-in opening book (names and ECO codes) stored in this page, so it works offline and understands transpositions. Stockfish is never used to name an opening — it only evaluates positions inside the lessons.
