They are hard to compare.  I suspect that Crafty is (or already has) closed
the gap between it and CB to a very narrow margin.  CB could do 5-7M nodes
per second.  Crafty can do that on an alpha right now, and then some.  Crafty
knows some things that CB didn't (king safety is one, some of the endgame
things like pawn majorities is also different from CB).

No idea.  I never try to make claims like that.  Much easier to just drop it
on ICC and see what happens.  :)

It will definitely be strong.
