Thanks for the feedback:

About the positions, I think they are correct as we don't use our own chess engine. Not sure about this...
About the board your correct, it's just a .map file and is easy to change.

We where indeed looking for a more visual approach.

About the camera, you can stop pushing buttons now , we didn't program a button to change the camera's view point. However every map has it's own camera positions. For some maps you don't have any good view on the board, on some maps it's somewhat better done.

I know the rules of chess, but I'm not an expert, so I apologizes for the chess mistakes (board and king/queen positions).
