Castling

Castling is a defensive supermove. It is the only occasion when you move two pieces and count it as one move. Castling involves the king and one of the rooks. The player may castle either to the left with the left rook, or to the right with the right rook.

Three conditions must be met to castle on the Hexes 4-Pawn chess board:
• The king must not be in check.
• The king and the castling rook must not have been moved.
• If castling right, the hex between them must be vacant and unthreatened.
