Ok.

Well I needed it to reflect -, 0 or + anyways so I should be safe. I
needed it to find out the direction of a chessmove so pawns could not
walk back and with that and the MIN and the MAX function I could do
with 1 for+while loops per direction (hor, vert or diag).

Oh, I am now on 32 hours of coding and started with 0 knowledge of
Python, PIL and/or Pygame and the 1st release should be out soon :-)
Just need to fix castling, promotion and en passant and I'm done! I
LOVE PYTHON.
