About the positions, I think they are correct as we don't use our own chess engine. Not sure about this...
Unfortunatelly they are not. Take a look here:

I do hope you find the way to fix it beacause those misplaced kings make the game allmost unplayable for me :cry:

I also agree with Traveler's point on camera view. The ability to rotate a view would be a great help.

Another thing is the tron map. It is too dark and it is allmost impossible for me to see the black pieces.

Anyway, as I said before the graphics is great, sounds also. Well done.
