What this board does
Lets you explore legal moves, including castling, en passant and promotion, using the chess.js rules library.
Your own lines
Trying a different move creates a branch instead of deleting the original line. Copy or download the PGN to keep your variations and notes.
Your privacy
The board processes pasted games and positions in your browser. A share link contains the position you choose, so share it only with people you trust.
