Black starts his turn with his pieces moved. This is caused by a2 a3 being translated internally to ( (1, 0), (2, 0) ), which is at the top of the board from White's point of view. This needs to dynamically change.

So, when I play with it, the letters flip, but the numbers don't. I can't figure out why. I think it's because the numbers are printing the range destination and aren't easily flipped. If they were printed more explicitly, maybe they would reverse easier.
