How would you handle this situation?

Live 3/6 game at the local B&M.

Hero is MP2. Villain1 is UTG and a young guy who I've spotted betting hands throughout and then either check-folding or betting and mucking cards w/o showing when called on the river. Bottom line, he will take shots at pots and make it expensive for you to call him down. I have not seen him 3-bet with anything less than two pair.

Villain2 is the Button and has sat down within the last 2 orbits and has not done anything to distinguish himself. He is the typical middle aged man playing casino poker.

How do we handle the turn? If we call or raise, what is our plan for the river? I sat at the table occupying myself thinking about this hand and decided that i probably screwed it up on the flop, but wanted a couple of second opinions.

Call down unimproved, raise if you improve.
