I am glad it did work on Linux :)!
I did wonder that something like this would probably exist for normal chess but did not do any research to confirm. And my first brainstorm idee was to make a normal chess variant to lose.. Fun to see that it is an actual real variant and popular and probably a difficult one also :D. Thanks for mentioning that and the wiki link! Great to read. (and I am glad I did change it to a bit different game with the lava & demons after all)
Yes the AI can be better and smarter and the bug sometimes occurs...not enough time unfortunately..
But I hope you still enjoyed it?!
