Uh, it's probably a blind steal if it's folded to the button and he plops down a standard raise.

You actually have pretty good cards agaist a random hand. If you REALLY think it's a steal, then re-raise. If you are not sure call, then bet out on the flop and see what he does.

If he's super tight then it's probably not a steal, and you should fold. If he's super agressive, then you should not call becauswe he will likely re-raise you on the flop.
