Yeah I play absolutely terrible at 250bb+ so I stop once I hit that. I have no idea how to play JJ for example. I folded once to a 4 bet and still regret it. In the WSOP once I had QQ mega deep stack and lost half my stack to AA. Maybe there's a reason I mostly win turbos
My biggest win was a mega stack challenge at Caesars tho so I can't be that bad. I was hyper aggro back then
Obviously tourneys are a different game, where hyper aggression is usually good because it's such an all-or-nothing type scenario.
Regarding playing JJ 250+ deep, it usually depends on the sizing of the 4-bet and the opposing player and his 4-bet range and what I assume his perception of me is at the time. I'm usually not raising there unless he's a psycho and so it's usually between calling or folding depending on bet sizing.
But as a general rule, vs. a sober random, they are never 4betting worse. Like ever.
