These situations suck. Even with reads, there's not much you can do.

My thoughts:

- Villian limped preflop. This makes it much more likely for him to be on a pocket pair than big pockets (QQ-AA)

- He raises the flop, and continues to bet when no overcard hits. HOWEVER, he pushes all-in on the river. Let's think about this:

If you were holding something like AJ, raised the flop got called, then bet the turn and got called, would you really push all-in on the river?

IMO, most likely holdings are:
22,77, J9

That being said, I'm completely torn as to how I'd change this line. I might fold the river, but fairly read dependant
