Well I still think checking back the middle of our range is neutral EV. It only makes sense to bet if we think villain will call with worse or fold better. This kind of reminds me of the KK on an A high flop problem. In this case we have no context, so it's hard to say, but I doubt many people ever c/c a river with the bottom of their range. Maybe sometimes they c/f the top of their range, but that also seems unlikely. Betting the middle of your range seems pretty bad. So I suppose it only makes sense to polarize.
No, it's +EV. There are no cases where we lose money, but there are cases where we win money, so the EV > 0.
