USCF Rating of Charles Xavier and Magneto?

Hey Guys,

Those two from the X-men series were playing the heck out of chess. Do you think they are expert class players or what?

If they did exist of course.

Anyone?

I would guess experts. Why not. Xavier could read the minds of opponents and be at least as good as they are. He should be at least an expert being exposed to that many ideas and thinking processes. Magneto is a genius too. I'm sure he doesn't like to lose. Xavier and Magneto wouldn't be playing if the outcome was already predictable. Magneto does lose in the movie and it looks pretty bad, but it is just one game. 

These guys are plotters! They hold the fate of humanity at their whims. Of course, they are Experts!
