This looks like a challange, but I haven't received an e-mail yet. Also, when I click on view, I see:
This preset for Falcon Chess should enforce rules and spot check,
checkmate, and stalemate.
Illegal move on turn 0:The move do is not well-formed.Go back and try again.

Don't worry about it -- I'll figure it out at some point.

Jeremy, I'm at work and don't have access to my admin password. Could you do two things for me? First, delete complete-permutation.zip from the zillions directory if it is still there. Second, remove the deleted mark from the index entry for Complete Permutation Chess. Thanks!

PS: If you're feel like it, could you simply remove the whole 'Computer Play' section from Complete Permutation Chess page?

Jeremy, I de-indexed Complete Permutation Chess as George requested me to take it down. I did not realize this would leave it searchable. I guess we'd better just delete it.

Actually, this game has been invented before and is even on this site, but it is also rather well hidden here (we never have figured out how to properly index the modest variant pages). There is also a ZRF file for it.

You may capture a piece that is adjacent to the Long Leaper, but you may not capture a piece that has another piece adjacent to it in the line of movement. It's an awkward usage, and I should rephrase it.

Well, I'm curious about your opening, but with only one move, I can't really say much yet. I've noticed that many players like to start by exposing their Advancer, while lately I've been experimenting with getting either the Swapper or the Withdrawer out early and then trying to use the leveling effect of weaker pieces to allow me to get some early material advantage. <p><hr><p> Interesting set of guesses about who did what to Rococo, and not too far off. As I remember the sequence, David and I fell into correspondence about pieces and features for a possible Ultima revision shortly after the Robert Abbott interview (in which all of the editors were polled for questions). At some point I put together a 'strawman' design for a revised Ultima, which added the ringboard (borrowed from Jumping Chess) and replaced the Pincher Pawns with Cannon Pawns (which were a rationalized version of my Wallaby piece from Edgehog Chess III) and replaced the Coordinator with the Swapper, which did not have capture by mutual destruction yet (all of these features were there to address Abbott's complaints that the Pincher Pawns and Coordinator were too unclear, and that the Long-Leapers were too hindered by pieces hugging the edges). David added the Advancer, and reordered the array (in two steps), and at some point in the playtesting, we added Pawn promotion. The last touch was the Swapper capture by mutual destruction, as I was sort of worried by the low value of the piece (Fergus, who was also in the correspondence, but went his own way with Superemo, disagreed). <p> At the end, David and I figured that what we had wasn't Ultima any more.

You can't blame Tony for various proposed additions or variants to Rococo -- those are my fault, perhaps aided and abetted a bit by Antoine Fourri

I'm afraid White's move 24 is illegal, as only capturing moves may end on the ring squares, and then only if necessary for the capture.

No, I didn't forget that rule, actually.

That interaction is why I tend to be reluctent to make captures that lead into a forced capture the following turn, since it gives your opponent essentially a free move. When that following capture itself ends up on the edge, it's just too risky for me. The result at that point is a bit like playing Progressive Chess, since your opponent gets several free moves. <p>I'd please to play you again at any time, Tony.
