[private joker]

Justin is only paying off with a smaller pair if he puts us on a really small pair (which we won't have raising up front) or KQ for the bluff (which we won't have because we called the flop, and a player with our image wouldn't call that flop without at least a pair).

So that means he probably won't call a bet with a worse hand. And he won't fold KK/QQ. So I check behind again.
