Mouse tricks
Scroll over the board to move in the game. Scroll over computer variations to preview them. Press right-click (or shift+click) to draw circles and arrows on the board. For other colours, combine the following with right-click: Ctrl or shift = red; command, alt, or meta = blue; a key from each = yellow.
