I added some Alfaerie pieces to this page and to the preset. Since I don't have a custom Alfaerie piece for the Decoy, I used an equesrex. Since I don't have one for the Spy, I used the spider. Like a spider knows what is happening on its web and how to move safely along it, the Spy gets intelligence on what is happening on the board and how to safely move on it. Also, spider starts with the same syllable as spy. But if someone designs some custom piece images for these, I might use them.

But 960.

Thank you're welcome! For the pieces' image, you can either view the page source or click the underlined here then tap and hold the piece image then open image in new tab.

Note that my implementation is not accurate with the rules written here. Moving a pawn using another piece to a promotion rank does not promote that pawn, instead the pawn gains Rook moves.

This gave me an idea for an army for CwDA.

I am having concrns that the spy is too powerful. It is a very mobile piece that can very easily avoid capture. So I'm thinking of allowing it to capture on an attacked space, limiting its inability to move to an attacked space to empty spaces. This would give its intelligence a degree of fallibility. With this change, I would increase the attacking ability of the Decoy by not limiting the pieces its knight move can capture, which would let it check the eneemy king. I may try this in a new settings file, since I don't want to change the rules for ongoing games.

Hi HaruN Y,

I can't see what your variants have to do with my idea of the bull's eye, which concern the central squares d4, d5, e4 and e5 and where the pieces are given move possibilities corresponding to those of the queen and knight in combination.

Otherwise, I think the possibility of offering various variants in one diagram is very effective.

I combined my thoughts from last night with what was the alternate description for the Spy I had yet to try out and wrote up a new alternate description of the piece. While writing it, I covered one detail with more precision that should also apply to the current version. A spy cannot capture a piece that could capture it, which for the Pawn means it must avoid moving as one of its own Pawns when capturing one. This was coded incorrectly in this case, and I fixed it in the code of the current games. Fortunately, this bug had not led to any illegal moves.

I don't think incorporating a new idea in another variant necessarily makes the variant that originally presented this idea obsolete. Combining too many independent ideas just gives a messy variant.

The author, Vincenzo Rapisardi, has updated this page.

While working on my collection for frog/Hannibal/Waffle chess with Gryphon/Manticore and Falcon I am a bit confused where to actually put the Interactive diagrams. I think best, as there is an ai, would be to have a "try it" separate chapter (or "play it" if that is deemed as a better title). The way things are, "initial position" and "pieces" are both good places to put them. Please take a moment to think about this. Fergus, what do you think? Is it doable? The rest, what do you guys think?

My submission is ready for publication.

I had though is better to show the user first the setup, then introduce them the rules, and then offer them the chance to play the games. But I 'll do it the way the people with more experience decide

It seems to me that capturing a protected lion by a lion is an available move as long as the diagram understands. Anyway I won't do it and I imagine the AI does not do it either.

I am working on making display of Lion trading restrictions possible in the diagram as a side project. I recently found a way to get the coordinates and pieces from the last move of a game, which will allow enforcement of the counter-strike rule. Still not sure how to do the bridge-capture rule though...

[Edit] Successfully implemented the counter-strike rule in my prototype.
