Yeah I gotta do something about that. I have already changed the level generation so that the single wide bridges (that are bishop traps) do not appear at all in the early levels and are much rarer later on too. Ideally I would like to detect the states where it's impossible for either side to win but it's not all that easy to do. Like usually a queen can't catch a bishop 1 on 1 but sometimes they can depending on the terrain. And of course card effects add a lot more complexity on top of handling the normal cases.
