So it seems the computer's regular non-king pieces can move backwards as if they were kings, but not mine. Well that's ONE way of making an AI that is unbeatable. Why not just skip a few steps and make a checkers game that says "game over, computer wins, chump player loses" right at the beginning without any need for pieces to be moved? That AI would also be unbeatable, and it would be a real timesaver and it would accomplish the same thing.
