And when KJ or some other two pair slows down and just calls because they're worried about spades, what do you do?

EDIT: even if all of your outs are squeeky clean, you'll only get one bet out of him on the river a lot of the time, which reduces your implied odds. I think that means you don't have enough to draw to two pair or trips, and I certainly don't think you're ahead after the flop action against a "normal" opponent.
