I played this hand very passively but I feel like it's rightfully so. He is very solid. I think this is an obvious set or straight on any other board, however on this one it's a little harder. Fold the turn? Fold the river? am I being a pussy or just making a solid read? I mean I want to put this guy on exaclty QJ and nothing else. 18/8 stats BTW
