I've had a few times where I knew they were beat. Either preflop or they were just gonna be drawn out on.
Of that I've listened once, and that was actually with AA. (Yes I was right)
So go figure. I've folded them once on the bubble of a tourney,(purely on harrington logic, it turned out to be wrong that time, but I understand the logic, and it worked. Just chipped me bad.) and a couple of times after a A hit someone hard.
Other than that. I've had a real hard time getting away from them preflop.
Sometimes you just know they're beat, but how do you not call, preflop?
Now postflop it becomes easier, cuz then it's just a pair of kings. Any A sucker might catch so I'm aggressively cautious to the river.
Dependent on position.
