LP with 33, folded to you, you just got ITM, blinds 400/800

[doggin]

Down to three tables, you have above average chips with
32K and blinds are 400/800, in CO-2, and it's folded to you. These can be really
good spots to steal, with 33 (but lets say up to 66),
what is correct here?

Call and hope to see a blind fee flop, does'nt get any
cheaper than that.
Or raise 3x or even 4x with a 50 percent probability of
it being folded back to you. Along with a strong chance of seeing the turn free if they do call your raise. Is this purely stack size dependent?

Thanks for the input guys!
