Even weak tight he could easily be doing this w/ TT+. And he’s not even for sure going to get jiggy with a set. By the turn you beat 77+. I’d prolly bet/fold the turn as a dbl barrel is likely to kick out a weak tight w/ broadway overs or medium pp who’s willing to float the flop. If he calls your turn bet, I’d prolly see range of TT-KK (don’t know if this guy 3bets pre at all) that I beat and 22-66,99 that I lose to (if we assume he’d stay for two w/ 99 ovrpr) That’s 21 combos I’m losing to, and 24 I’m beating. If he’s really weak (ie. not calling 2 streets w/ anything less than JJ+) then that’s like, what, 18 losing to 18 winning… so I’m still calling a PSB on the river. All this being said, I don’t think AA is a big pot hand vs this guy on this board. And I’m not happy having to play it OOP for 3 streets….
