Each player calls the left-hand side of the board his "queen's flank" and the right-hand side his "bishops' flank"; note that they do not correlate (White's queen's flank is Black's bishops' flank).

Some variants have used other board shapes with quadrilateral cells. Triangular cells not on the perimeter
