Hypothetical situation. Opp is a 22/18/3 reg who doesn't get too out of line. I'm not sure how much he overvalues hands, i have a note that he is decent. and highly doubt he's ever been in this type of situation before. At what raise amount is a fold standard? And if it's some really really large amount what line would opp have to take to get you to fold?
