On this hand, I didn't thought villain had a set/2pair, otherwise, I would have expected him to raise somewhere.
On river, when he bets 2/3 pot IP, I can only put him on a Straight, maybe AK/AQ (possibly with diamond), 98dd or a bluff.
From villain's perspective we might as well have a Big Ace/bluff.
So indeed, our range seems pretty weak. Would that place be good for a bluff from villain?
