I'm a fan of just flat calling here, if you 3 bet and you get raised theres a good chance you are beat, what hands are going to 4 bet you on the river that you are beating - A-6 and A-8 possibly, Flat calling here will let you see his hand and will save you 2 bb if you are beat. You can rule out sets here possibly but the straight cards are what scares you, from my experience loose players in live small stakes games LOVE calling all sorts of bets with Q-J.
