Notes

First I found a board shape I liked. then I considered that rook like pieces would be somewhat restricted on such a board, but bishops could be potentially powerful. So I first place bishops at the corners, and then shifted on, to start them on different colors. Knight are also potentially powerful on this board. Longer leapers seemed out of place here. Since both bishops and knight are potentialy powerful, adding another piece of equal strength seemed unbalancing. So I added a Centurion, not qute the same centurion as in Archchess.
