Not yet but that would be pretty cool. I found a free bot (Cake) but the author has this to say about it: "Cake 1.8 is one of the world's most powerful checkers engines for the PC platform, and plays stronger than any human. It is quite frustrating to play against it, but it is a great tool for analysis." So that could be... fun
edit: oops hadn't noticed trgeoff's reply. So yeah chess is the only one for now. And yes more bots are in the long-term plans as well.
