Villain was aggressive and had made the exact same flop raise on the previous orbit. Plus, playing from the button, villain has a much wider range, and almost zero 2-pair hands. Plus, after 3-betting and C-betting the flop, if I call the flop raise I'm basically committed, so getting it in here is almost automatic.

Min-re-raise on the flop after I've already shown plenty of strength. I guess I'm praying (hopelessly) for AJ. Maybe hard to fold, but certainly not the spot to be pushing my stack in. One day I'll learn.
