NL100 extracting with turned aces up ip

[chris216]

Villain is completely unknown. I suspect some of you will advocate a raise somewhere. The reason I didn't raise was because I thought after the flop, he either has a set(a bit unlikely) or a small pair that is scared of the ace and will fold to a raise anyway. Advice?
