Well, you might imagine my thoughts to those rules. I acctually only read the movement rules for the new types of figures. You could add the rules for pawn movement in general and especcially en-passent. There are a lot of possibilities on how you wanted that to happen (even through some are very unlikely)

btw: I always think that the C stands for crusader not for cardinal

I think I fixed the bugs :) Now let's play !

(Yes I'll need to clarify some rules, I'll do that soon).

Yes I know this game was played badly by me. The problem is that I gained a rock on b8 somewhere in the fifth move. I am quite sure that it was gone after Qxb7 and not mistakenly left on the board. Good luck in finding this bug.

Thanks ! I reproduced the bug using your report. I can guess it's a wrong large castle which was done after the rook was exploded. Will be fixed soon (actually I thought I took this case into account :/ apparently not... sorry).

EDIT: Ok bug fixed =)

Looking at the problems that seem to come with castling I wonder wether it is possible to castle a promoted rock and a promoted king in extension (or a king and a rock in crazyhouse). I am not sure about the rules anyway and it is highly hypotetically. What do you think?

Edit: Probably I should ask about Loser aswell, but I never liked this kind of concept and it is the only variant I did not even try.

Castling is not possible with transformed pieces, no. As in orthodox chess a promoted rook cannot castle (I never tried that but I'm pretty sure it's impossible ^^). And castling is not available in loser variant since the king is a normal piece.

Some improvements achieved, for example it's possible to navigate in a game after it's over. And I fixed some bugs here and there in some variants. But the website essentially lacks players :/ and the rare times when I see someone online he plays against bots, not launching human games.

960bot is nice

gl anyway:)

You could help my luck by playing on the website against humans ^^
(Yes I know there are very few people online. But there has to be a beginning :/ If nobody stays online because nobody is online, nobody will never be online and the website will never work ;o) )

About the bot thanks, but it's really just a very basic bot, not designed to play well (and in most variants it does not). It's here to help learning the rules before playing human opponents. (Yes, I know... :/ )

In this game of atomic the win is only achived after some moves after ent passent removed the white king. (In humen games that should not be relevant.)
