I know both of my opponents are passive, so if I get raised, it's an easy fold, in fact, most aces of theirs wil probably just call. Despite that, I'm still not convinced that there's value in a bet here. What's calling me that I beat? 99 and TT if the raiser raises that. Any 8 or 6 from the coldcaller. But shouldn't I expect to see Ax, KK, and QQ more often than makes a bet here profitable?

Does anyone's decision change if the action is the same on a Q or K river?
