So many variables to be considered here. How much you are up or down, how much it will cost you on the turn or river, how healthy your bankroll is, how long you have been sitting at the table winning or losing, your stack compared to your opponents stacks, if your girlfriend isn't mad at you, if you have been eating healthy meals, if you worked out that day etc... I believe that 99% of live poker situations are unique. There's never two situations that are the same. So it's very hard to even make an opinion on what to do in this particular situation. So many variables that aren't accounted for. Anyway...personally? I fold to the $65 post-flop bet or raise $180-$220 on top of the $65 and truly commit yourself regardless of any persons actions thereafter. BOOM!
