p.
- Instead of a normal move, a piece may be exchanged with an adjacent friendly one.
- Switching can move pawns until rank 1 or final rank. In the first case a 2-squares
- jump is possible, and in the second a promotion occurs.
- Switching must involves two different units.
- Switching while the king is under check is not allowed.

- Note: if the king and rook are on two adjacent squares, castling and switching
- from the king are triggered in the same way. Castling takes priority:
- if you wanna switch, use the rook.
+ Note: to trigger a switch move involving the king, select the non-royal
+ piece first (to not interfere with castling).
