Promotion

When a pawn advances to one of the five hexes at the far edges of an opponent's tridrant (a3, a2, a1, b1 or c1), it must be exchanged for a piece of higher value, usually a queen. (You may not exchange a pawn for a king.) You may have more than one queen when you promote pawns. An upside down rook can serve as your second queen.
