I’m looking for a Chess client that supports XBoard and UCI protocols, preferably one with a 3D board. Couldn’t find anything so far. Everything seems to be 2D only.
Oh, and BTW, I installed KNights for now. It comes with an engine preinstalled (GNUChess IIRC) and it allows to use other engines also (I tried and installed stockfish) but I just can’t find any option to adjust the difficulty for any engine?
Another option would be to register at one of the big chess sites, if you’re into Chess for more than an occasional game. Those have decent graphics, a lot of statistics and a ton of other features.
