A square that a main Middle board piece sits on has corresponding square in Above and Below boards. These locations (departure square) 'influence' whether a move can be considered or not. To make the move, it also must be legal within the Middle board. Sometimes the Above or Below two piece-types move their one- or two-square way, and other times they duplicate a Middle board movement. Rules may very well be interpretable (including moving opponent's piece) in all cases.
