How to play

White moves first, and any move that leaves your own king in check is never offered as legal.
Castling, en passant (legal only on the immediate reply), and promotion to queen, rook, bishop, or knight are all implemented.
Checkmate, stalemate, threefold repetition, and the 50-move rule all end the game.
Checkmate still wins even when the 50-move clock is already full.
