Ok, here's my opinion and I could be wrong...
Usually in those limits, when a tight player limps/calls UTG pre-flop, I would probably put him on a small pocket pair between 22-77. With that being said, the bet on the flop was good. But when he just smooth called OOP on a board like that, I would be a little concerned as I may think he flopped a set. I don't think he would have small connectors and be on a draw. So to manage the pot, I think a check on the turn would be better and deciding if you should call whatever barrel he fires on river. But maybe the check on the turn is not +EV against him? I dont know.
