Bug fixed, thank you ! :)
New variant implemented : Ultima chess (or Baroque chess), as initially described here www.chessvariants.com/other.dir/ultima.html with the modification concerning the immobilizer described there http://www.inference.org.uk/mackay/ultima/ultima.html
This variant is a quite complex and may contain bugs (more than others). However I fixed as best as I could for now :)

It is not clear that a long leaper can move more than one square and then capture. (draught is played with different rules in different regions around the world). Otherwise this is interresting.
Thanks

Hey i noticed you added grand chess 10x10!
And there were people online :D
still id be nice to play computer while waiting for humans cos i dont feel like being idle very long^^
Also i promoted on the 8th rank? could promote to knight bishop or pawn and pawn moves backward again. not sure here :)

"It is not clear that a long leaper can move more than one square and then capture"
--> Yes sorry I wrote the rules quite fast. I'll clarify this. (However, I'm pretty sure that international draughts on a 10x10 board have just one official rule :) )
"still id be nice to play computer while waiting for humans"
--> You can ! It was one of the first features ^^ Even if you started an Atomic game (for example) and open a new tab, you'll get a warning "you already play in another tab!" but can dismiss the message and play against a bot. But if your opponent is dead, you can also resign :/
"Also i promoted on the 8th rank?"
--> Promotion is optional on 8th and 9th rank, mandatory on 10th rank. That's why you can choose a pawn. Besides, you can only promote into a piece that was captured (by your opponent).

I think I found a bug: Shound't the ninth black move take a pincer by pincering it between the moving cameleon and a pincer?

To your first question: no, because to capture (a pawn) as a pincer, the chameleon must move as a pincer. In this example it moves diagonally.
The last example is quite weird because the FEN is good (queen at a1) but is transformed into a knight... I'll have a look, should be easy to fix. But since I'm doing some big changes to the website - to allow publish and solving problems - I cannot do it right now.
EDIT: ahhh I fear that the problem comes from the fact that the AI plays the move after a human game is started... So OK I can fix that now :)

Hey
true that you can lobby while playing AI, which is an excellent option! Not sure if you can return to the AI game afterwards?
Also i think there might be something wrong with the PGN/FEN output.
The starting position (960) isnt recognized and sometimes i cant import the game even after fixing the fen. Itd be nice to have this working properly again:)
Next time i come across ill send a bug report

"Not sure if you can return to the AI game afterwards?"
--> No you cannot, because "AI" games are not considered as interesting as games vs. humans (AI is just basic shallow alphabeta search... it may appear to play not that bad in some variants but only because we are not used to these variants :) ). If at some point I can improve the AI level then I'll reconsider that, but for the moment AI moves are just slightly above random play. Yes I know I struggle in Alice and Ultima at least. But Alice is depth 3 search and Ultima depth 2... ^^
EDIT: I think i'll change that anyway, soon. Despite AI level, it would be more logical. When a human game begins, store current computer game state. When it's over, pressing "new computer game" should continue from the stored state.
Re-EDIT: well I'm really not sure. It adds complexity for too little gain I think.
"The starting position (960) isnt recognized"
--> What do you mean ? Recognized by a software ? Yes the FEN lacks the final "moves counts" + enPassant square, things like that because I didn't need it. But I'm adding problems, which will require something like that. But most probably not moves counters. So it may remain not compatible (but you can add the missing FEN data easily; I'd be curious to see cases where you cannot fix the FEN).
