Folded to you in the SB, what do you do?

It's folded to you in the SB, levels 3 or 4, 5-7 handed, and both you and BB have more than 10xBB. Do you regularly take a shot at the pot here? Raise pf with any two? Complete and fire into any flop? Just fold unless you have a good hand, 1.5 BBs isn't worth it?

Here's an example of what I mean:

Level 4 (blinds at 50/100) of a Party 22.

UTG - t1200
MP - t1300
CO - 1000
Button - 800
SB (Hero) - 1900
BB - 1800

Folded to Hero in the SB with J4o. What's your move?
