Her game was already produced in the 90s, and if people don't know how to play it, they won't be playing it. Anyway, if these games happen to be identical, it looks like the Devingt Chess inventor will get the credit for the game, and the Cardinal Super Chess inventor will not. My experience, though, is that people who independently make similar games usually don't make identical games.

I have contacted the creator of Cardinal Super Chess to know the details of her rules (castling, initial P's move, promotion). She replied "My board and innovations are copywritten. I am not revealing all my rules as yet, until I produce it. I have some special rules. I know you understand". To be frank, no, I don't understand the need to hide rules of a chess variant. But I respect that choice. Whatever, I think I have my answer, it is very unlikely that Devingt Chess has been copying Cardinal SC, as I was suspecting knowing its author, quite poorly informed about chess variants.

Wonderful. It seems to work perfectly fine. Thank you

I think I fixed that now. Try it again.

Yes I agree. Thanks for coding the GC for Devingt Chess. But according to the tests I've made, the Pawn's promotion doesn't work. I get a rectangle with ? when the Pawn reaches the last row.

Yes, certain ideas seem to reoccur more often to people thinking up new Chess variants. It's good to keep a public record of them so that people don't keep reinventing the same game. For example, several people separately reinvented Spherical Chess, and some versions differ from others by only a single rule.

I added a note to mention the similarity with Cardinal Super Chess. At this moment I don't know what were the details rules. The inventor of Devingt Chess was ignorant of Cardinal Super Chess nor the other similar variants. It seems that this game or a similar one is, like chess for 3 players, chess for 4 players, chess on hex, a chess variant which is "invented" often and rather regularly. This one is not the first and probably not the last one on 10x10 boards with Camels.

I don't have a set myself. David and Hans each had one, and Hans programmed a Java applet to play it that appeared on the website for the game.

Do you have more information on Cardinal Super Chess. I mean more than what is in Pritchard's? I wonder what are the rules for Pawn's initial move, castling and Pawn's promotion. These were probably described in the game leaflet but I don't have it.
