Premise 11: Restrict the board to 64
usable squares.
This premise really restricts the possibilities. If we look at the
factors of 64:
2
8
or 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2
for three dimensions gives these possiblities:
2 x 2 x 16
2 x 16 x 2
16 x 2 x 2

2 x 4 x 8
2 x 8 x 4
4 x 2 x 8

The simplest, most regular arrangement would be 4x4x4, or four boards
of sixteen squares each. The classic Tridimensional Chess variation
uses three boards of sixteen squares each plus four
attack boards of four squares each, or (4x4x3) + (2x2x4).
I vote Premise 11 as the one most likely to be violated.
This board is 8x8x1, and can be considered a degenerate form of 3D
chess. All 64 cells on the chessboard are usable.
This board is 4x4x4 with boards not offset and varying cell markings.
All 64 cells in the chessboard volume are usable. More details are
here.
This board is 7x4x4 with X offset boards and constant cell markings.
64 cells of 112 in the chessboard volume are usable.
This board is 4x7x4 with Y offset boards and constant cell markings.
64 cells of 112 in the chessboard volume are usable.
This board is 7x7x4 with XY offset boards and varying cell markings.
64 cells of 196 in the chessboard volume are usable.
This board is 5x5x5 with boards not offset and varying cell markings.
An additional piece, the Mace (a.k.a. Unicorn), is introduced for the
additional file. All 125 cells in the chessboard volume are usable.
(This variation violates Premises 7 and 11!) More details are
here.
This board is 8x8x8 with boards not offset and varying cell markings.
All 512 cells in the chessboard volume are usable. (This variation
violates Premise 11!)
This board is 6x10x7 with Y offset boards and constant cell markings.
64 cells of 420 in the chessboard volume are usable, with 16 of these
moveable during the game.
