No hands on villain. Complete unknown.
So the flop comes down about as bad as it can in a 4-bet pot for AA. So pretty standard check back I think. Though we likely wouldn't check back with a set so it turns our hand face up as either AA/AK/AQ/AJ or a random bluff that gave up. With that in mind, does anyone prefer a 1/3 PSB?
On the turn, does anyone fold?
On the river, does anyone call?
