Instructions

• Normal moves: Put the mouse cursor over the piece you want to move, push the mouse button, move the cursor to the destination, and let the mouse button up.
• Castling: Move the king two squares left or right.
• En passant captures: Move the capturing pawn diagonally as if doing a normal capture.
• Switching sides: Type 'g' (for "go") with the mouse over the board to tell the computer to make the next move.
• Takebacks: Type 'b' to take back a move.
• Restart: Type 'r' to restart. Also used to claim a draw.

For the moment, pawns always promote to queens.
