[bookish]

Why are you playing both $3 and $163 tournies? You are either wasting your time in one, or hopelessly outclassed in the other.

I'd encourage you to remember than noone (well very few) at the high buyin games plays a hand in isolation. They remember your action before, will have been looking at the hands you play and how you have played them.

I'm guessing, but I suspect that your previous action was analysed so that villain in hand #2 put you on air. Are you thinking about the image villain has of you? You claim that you can bluff the straight. Virtually no-one will overbet with the nuts, unless it is a cunning double-bluff against a villain with previous history, so its virtually impossible for villain here to put you on that. Its possible this image was reinforced by you slow-playing some made hands earlier.
