Henry, I think in this game rooks and bishops move as usual (ignoring the rotation of the board).

I think exchanging places of rook and bishop is better because bishop isn't colurbound and rook is colorbound in here.

Not sure if this really belongs as a comment on this page, but here goes. Raumshach is a bit like a diagonal game, but in higher dimensions diagonal starts to have different meanings (the colloquial 'triagonal', etc.) I've taken to giving the number of dimensions that are 'lateral' versus those that are 'attacking'. So Raumschach is 1-lateral and 2-attacking. Some of the very large 3D (8x8x8) variants are 2-lateral and 1-attacking. Most 4D variants are 2-lat and 2-att. Ordinary chess is 1-lat and 1-att, whereas Diagonal chess is 0-lat and 2-att.

The idea of having the camps in opposite corners is one that keeps recurring. If you turn Raumschach on its side you will see that that too is a corner-based variant, and the Pawns move accordingly. This one must have slipped my mind when I came up with A Cornucopia of 9x9 Corner variants, or I would have credited it. Just in case this variant was a subconscious influence I have now done so. One of them uses FIDE pieces but doubling the numbers of most, including Bishops, avoids the need for an asymmetric array.

I've been toying with a similar idea for the last couple of days and decided to google it. I'm happy to see other people have also thought of this. All in all, I like your initial board setup but I don't like the knight movement change and the pawn promotion rules are hard to learn. Diagonal chess should be casual, fun and easy, when you are bored of the normal one! In my current design, pawn promotion only happens at the very last square (H8). This might seem near impossible to achieve, but my pawn movement is also different. You can move them in either diagonal and only eat straight forward. Exactly the opposite of the image above. This makes the game completely different and quite fun, as you can group pawns from different lanes together in creative formations. I have also toyed with dropping one of the bishops instead of the 8th pawn. The initial board setup is thus different, with a knight by each rook, the 8th pawn in the center, and the queen and bishop adjacent to the king.

A friend and I 'invented' a variation like this independently, except we had the knights moving 'normally' -- just the pawns were different. And we didn't do pawn promotion at all. It made things a lot more interesting without having to remember a whole new set of rules. Normal chess stategy almost applies, but also keeps tripping you up as you forget which way things are going! Like the description says, one nice thing about this is that you can use a regular chess set -- important as we only had the one!

At first glance I thought the promotion limits rather odd, but now I can see that the Queening squares are indeed harder to get to than other promotion squares from binomial theory. It still seems slightly odd that the Knights have been turned into Camels in all but name, although it is a good illustration of the connection between the two leapers' moves. One thing to do with the 8th Pawn would be stick it on top of the left Rook to represent a real (unbound) Knight. That way the radial linepieces would be one bound to each square colour on the left and a single unbound one on the right, and the oblique leapers would be the other way round.
