I'm thinking about folding the second nuts.  But at this point, how could I fold?
He could have AK, AT, A9, A5, 9T.

 Ok, so at this point it is pretty clear that tonkarock1 has a set of 5's or 9's.
I didn't think he was the type of player to flat call a raise preflop with AA.  It
Also seems pretty clear to me that Goink is rockin a set as well.  The question is,
is it T's or A's?  With so much money in the pot, this would be an absolute heart
breaker if I make a bad fold, but I still have $1500 to save if he has the rockets.
