Have you been raising a lot in late positon? Do you think he's defending? Well I think him defending with any two is out the window after his turn bet, obvious of course after you shove and he calls, but trying to disregard his all in call on the turn after your shove I would say AJ, AQ, AK QQ's are all in his range unless he is a defender then it opens up, but seem unlikely since you have one of the Aces AA also way down the list 8's also seem unlikely for the same reason but all still possible. Is he such a maniac to bluff in this spot? I think you can get a better read on the hand if you reraise on the flop, kind of lost becasue it's a pretty wet board and the turn makes it even worse picking up the FD, if he does have a monster (AQ, 88,) he can't really check the turn because of how wet the board is so if he is one to always lead then his bet doesn't tell you as much as calling a reraise on the flop would. I think Ak and AJ are the most likely hands, Kings are possible but find it unlikely (not knowing much about this guy) since this much action on that board with an A so I'd have to say AJ or AK….. and of course that river sucks but just analyzing it from the turn down, and not being results orientated.
