Deep 30NL - I have two-pair. What do you have?

[AAmucked]

I have 27.60, villain covers. I bought in w/ 25. I was pretty lost in this hand and wasnt sure whether to raise the pot OOP or just check-call it down. I had no read on villain at this point. I initially thought about 3-betting preflop but decided against it with no read and a strong hand. Then I got overly passive - or did I? Comments on all streets welcome.

Also, this was a 60 max-buy-in game. Should I describe it was 60NL or Deep 30NL or neither? Thanks.

Too passive. Some will say 3-bet pre. I usually don't unless button has been raising habitually. C/R flop to pick off c-bet. I think we are fine with taking it down right there with this board. If called, 3/4 pot turn.
