No, it's always neutral EV...
Players who complete the SB almost always either have weak hands that can't stand to a raise, or have hands strong enough to see a flop, but you get to see it with initiative and position, so you have the advantage. Raise pf %100 of the time.
As played I can't really fold. He could have slowplayed an overpair, a set, could have two pair, could be a monster draw, could be a smaller straight, could be a lot of things. Too many non-KQ hands in his range not to call here.
