Villain calling with pocket 3's which is probably a fair call putting me on an overpair. When he called the flop I was thinking he could be on a straight draw and when he called the turn I thought maybe he already had it or had hit a set and it was a trap. Either way it was getting expensive since I had missed completely.

Personally I would have been inclined to fold on the turn bet in his position.

In the end it was a trap as he checked his set on the river - who wouldn't?

Stats/Reads? I think we need to introduce you to pokertracker...

That's disappointing, the info you get from them can be valuable. You start shoving HUD stats in my face I can tell you all sorts of crazy stuff your opponent does. Reads are nice too though, simple actions are very often indicative of someone's skill level and overall play style.
