AK OOP against a PFR question

[Reef]

A84 flop is VERY different than a KQ4 flop, obviously. On the hand you linked, I cringed when villian raised all in on turn. All hero can do is beat AQ or bluff (next to 1% probability of that). On an A84 flop, the AK is MUCH stronger. If villian has AA, pay it off.
