NL100 6max: Overpair but no idea where I am at

[XST]

Villain is 64/17/2.5. I am totally confused in this hand. Villain limps then min raises, I assumed this was sign of huge strength like QQ+. And decided to call for set value. But am wondering if maybe my hand is good. Any thoughts?

c/c. sometimes you see idiots do this with hands like JTss and suited broadway/AQo+

you can b/f as well. but when you bet expect a min raise [img]/images/graemlins/smile.gif[/img]

How's your image been? I've seen aggs do this minraise preflop to basically try to cheaply define your hand before they really get involved. If you call they can most likely put you on some kind of drawing hand/low pair and capitalize on the 2/3 time you miss. If you 4bet pre, they let it go cheap.

villain is super loose here with a nice AF. I usually try to showdown cheap for the simple fact that we are ahead SO often. However, we don't want to embrace variance and stick it in when we are dominated. This flop basically makes the play the same as if we were PF I feel. What I mean by that is, you basically have to ignore the flop and try to pull more info.
