An interesting concept to extend Alice Chess' idea. I'm inclined to think (but lack the mathematical skill to prove) that the connection between the three boards is a 4D one in disguise - bishops, if they were present, can travel paths one board at a time back onto their original starting board, arriving there on square(s) (e.g. their exact start point) that they wouldn't be able to reach if the variant was truly 3D (like Raumschach is).
