Big Angora Rabbit vs. domestic cat: who would win?

This is just hypothetical. I'm only asking because my friend has a huge
Angora rabbit -- the
thing must weigh 50 pounds. My mom's orange tabby only weighs 23 pounds and
he's supposed
to be a big cat. I've seen rabbits play fight before -- another friend of
mine used to have a
playful normal rabbit that would play fight with him -- and they look pretty
capable to me. The
rabbit punched and bit my friend so much he had to stop play fighting w/the
rabbit (and yes,
the rabbit seemed to be having fun too). But, my friend says that since cats
are predators
they would be able to kill even this big Angora rabbit. I just don't see how
it's possible, if
it's a straight up fight (i.e. the cat doesn't ambush the rabbit).

I'm not going to fight a rabbit and cat, this is purely a theoretical
thought/question.
