Chess Hard

Controls You play White and move first. Select a piece to see its legal squares, then select a dotted square to move. Full rules including castling and en passant; a pawn reaching the last rank always becomes a queen. Stalemate, the 50-move rule, threefold repetition and insufficient material are draws. Keyboard: arrow keys to move, Enter/Space to select. Only checkmate wins are ranked, and fewer moves ranks higher.
