I don't mind the reasoning behind the PFR but there aren't too many hands worse than 83s HU.
But having raised pre flop, your plan goes south when bet in to on the flop. SB has made something or suspects strongly that you have not.
The raise is fine in my opinion - for the free card possibilities, to assert authority and to a lesser extent - information. Plan goes even further south when you're 3bet. You have your info. SB has definitely made something stronger than a pair. 2 pair, str8, trips.
Turn - fine.
River - fine. I think you're winning this showdown like never. The no hesitation 3 bet was a death siren, I expect boat or str8 95%.[img]/images/graemlins/frown.gif[/img]

Edit: The only time you save bets here, is if SB shows you his cards on the flop.
