White to play (Regular moves apply except for Black King) Black King or Shadow King can move to "any" square that is not attacked by white pieces. It can not capture its opponent. When not in check and there is no unattacked square available, the Shadow King wins. Play the least moves to checkmate the Shadow King.
Here is a scenario where I think there are no unattacked squares on the whole map and the king is in check. I will not list all the moves needed cause the list is too long.
EDIT: ok my scenario still has holes...I give up XD
in case i understood wrong and the king can only move 1 square at a time, since he cannot capture my pieces, all you need is 1 move. Put the queen 1 square up from him.
