Perhaps, I don't understand this correctly. Don't you ignore all possible search
extensions, that might be triggered by the move here.
Or is the "if(in_check(OTHERSIDE(whoseTurn)))" taking care of the check
extension. (I am not totally sure, whose turn it is ...) It could also mean,
that this is just the legality check. Or do you generate only legal moves?
