Here's the full move of a Cardinal (Knight + Bishop) with both boards empty:

However the following constraints hold on moves that change board to avoid changing color:
Thus the King can not move into an attacked square, then fall through to an unattacked one, and you may not move into a square occupied by a friendly piece, then fall through to an empty square.
You may capture a piece on a square of the other color than the capturing piece is bound to, as long as the equivalent square on the other board is empty. This makes off-color captures (there's a term for you!) rather like Locust (leaper) captures. A pair of pieces occupying equivalent squares on different boards (say 1a1 and 2a1) are immune from capture by off-color pieces, but not, of course, from pieces on their own color.
The Cardinal is the usual Bishop plus Knight.
Pawns also move and capture as in FIDE Chess, including the two square initial move, except that there is no en passant capture, and promotion is to Rook, Queen or Cardinal only.
Kings also move as in FIDE Chess; including castling by moving two squares toward the Rook (which when castling kingside lands the King on the Rook's starting square), even though the board is smaller. Note that castling on kingside lands the Rook on a square of the opposite color, and thus causes it to land on the other board. So, if White castles on kingside, the White King ends up on 2f1, and the White Rook on 1e1.
That got me to Monochromatic Alice Chess, but it still had some issues. Bishops would never change boards, and Knights would be forced to with every move. This would reduce their value relative to the Queens and Rooks.
Along came the 84 Squares design contest, and it occured to me that 6 x 7 x 2 = 84. When I wondered what I could do with this fact, I remembered Monochromatic Alice Chess. Cut it down to an array of 6 Pawns and 6 pieces? Then I thought about Lilliputian Chess -- because it squashed the Knight and the Bishop together into an Archbishop (which I called a Cardinal in this game, as the name Archbishop is used for a number of different pieces), removing the strictly color-changing and colorbound pieces.
The game was almost ready. Initially I had both sides starting on a single board, as in Alice Chess. However, pieces on the same color square as the King have an advantage in attacking the King, since the King can't protect itself from them by having a friendly piece occupy the equivalent square on the other board. Considering the example of Ralph Betza's games Colorboundmost and Nearly Colorboundmost Chess, I decided that the game would play better if the Queen and opposing King were bound to the same color square. Moving the White array to the 2nd board did that neatly, and also preserved the traditional "Queen on color" rule.
The final thing to be tweaked was the Pawns. Initially I had followed the rule from Lilliputian Chess that Pawns had no initial double-step. However, in playtesting the poor things never really got anywhere, so I restored the double-step. I left off en-passant capture for two reasons: first, it is highly unlikely given the board, the movement rules, and the starting locations of the Pawns; and two, in general I feel it a bad idea on a board only seven ranks deep.
While pieces on squares of the same color as the King attack the King more effectively, it is not necessarily true that pieces attack other pieces on squares of the same color more effectively. This is because while off-color captures can be blocked by a piece on the equivalent square on the other board, they are harder to defend against by threatening to capture back, since a piece that protects another piece against same-color capture by definition does not protect it against off-color capture -- it's on the wrong board for that.
With its theme of colorbound pieces and differing same-color and off-color captures, this game seems to have a thematic relationship with both Interweave, where pieces are colorbound, and only capture pieces on the other color, and Separate Realms Chess, where most pieces are colorbound, except when they capture.
Thanks to Tony Quintanilla for his help in playtesting.
