Caught between a spew and a scare

[TarHeel100]

I was new at this table and had no reads yet. I'd like to see how others play this. I suspect MP1 is going to continue to spew down thru the river w/ probably either AK or KQ. Of course, button capping the flop in the face of this action on a ragged board makes me very afraid. I'm thinking it's going to get very expensive to see the river and I may be looking at a chopped pot in a best case scenario.
