[pottie]

Thanks everyone for some interesting discussion, seems a call is best here although there might be merit for other plays against certain opponents.

For those results orientated like me...
I was lost on the flop, went with my first instinct and raised it up to $140. UTG pushed $485. I decided I'm committed and called $345. UTG showed AA. Pottie wins the pot with the flush card on the turn, river blank. My advice - if you misplay a hand get lucky.
