Greetings!
I'm working on a project about chess engines and was wondering if that works like this: the user enters move notation (e7, Qa3, etc.) and then engine responds in kind. I figure this kind of engine would be useful for practicing blind chess and other things, but the closest thing I have found to this is an engine [1] where one may input moves as e6-e7 (instead of simply e7) and e7-a3 (instead of simply Qa3). This is good enough, of course, but the little change would really enhance the experience. I understand that this is quite difficult though, haha.
Thanks a bunch!
Ali
