Pre-flop Decision

Ok im having a $5 HU tourni at my house with my friend and, he's kind of a loose player, doesn't really pick his spots well to bluff. FPS's alot, and doesn't think about odds with all sorts of draws. Raises almost everytime button is passed back to him.

Villan: T1500
Hero: T2500

Blinds:25/50

I wasn't sure the proper +ev play with this hand since, one he limped from the button and it's somewhat unusal of him. Second stacks were much to deep to push and risk the coinflip. But is this still a raising hand when your OOP when every card [except 2] would be an over card or do you just check, and play the flop.

Dealt to Hero: 3c3s

Villan: completes
Hero: ??
