semi-bluff flop raise

Villian is somewhat loose, typical low level player. He also has been trying to steal a lot of blinds. Is this a good play to make in these situations, or any other?

Also I assume I should've reraised this flop though I think his line would be the same.

Also of interest is what to do against a possible bluff reraise.

You can either 3-bet PF or you can flat call PF and raise almost any flop. I personally 3-bet PF.

Yeah, I wasn't sure how common this was. I actually put villian on probably complete air here preflop. he may try to bluff reraise though, i might just call down then UI.

with a 3-bet pf, what's your action if he leads?
