Small pot, Mid Pair - How do you handle this?

[Saint_D]

Villains are 30/1 ish. They like to bet when they have a hand, but I don't have enough hands on the bettor to say I have anything other than a vagueish idea he probably isn't bluffing.

Final Pot: 5.50 BB


Flop: Would I be better off check raising? These guys are fairly passive and I think it checks around 60% of the time.

Turn: should I have kept firing?

Small pot, I am thinking I should have folded the river bet. Thoughts?
