the bad thing here is that river complets so many draws. Of course its high card bord and you can make him fold a 5x and Qx but most of the time I think you get called by flushes, some 2pair hands and JT. Dont expect bad players to fold like 2 pairs and Kx hands because river sompleted flushes and straights and you could have hit your ace. they dont think about the hand the right way and call. I would probably shove non flush ace river but giveup this one. Most the fish are going to bet river with their nut hands, but some of them just dont, I think small flushes and 2pair hands is when you get checked to quite often. They feel somehow it isnt that strong of a hand but they just arent capable of folding.
