[Phat Mack]

I think the crux of the hand is your read of Stubborn on 3rd street, and the range of hands he could have to go to war with his third raise.

It would also be interesting to know what he thought of you, and what he thought your complete meant. In some situations his three-bet might mean a big hand, in others it might mean he thought he could get it heads up.

So many of Stubborn's possible down cards are dead. Would he be pounding with a 776? Does he have one of the two remaining aces? One of the two remaining 5s? He doesn't sound like he would have a big hidden pair...

I think you played this fine, but I'd be peeing a little in my pants here. The best case scenario seems to have him with two-pair and low draw.
