well i completely agree with your logic and use it regularly. but in this example, hero is against an opponent who he doesn't have a good read on. only the fact that villain has seen you and expects you to throw in a continuation bet after every preflop raise. i guess i'm going against an "average" opponent: no solid read, he's seen some of your stuff, not too donkish, not too tight. how many barrels do you typically throw out when you hit nothing but air?
