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

  34     Note: if the king and rook are on two adjacent squares, castling and switching
  35     from the king are triggered in the same way. Castling takes priority:
  36     if you wanna switch, use the rook.
