I like a fold versus most people and this sizing
He doesn't have many natural bluffs since he had to call a big bet on flop, and he does ahve a ****ton of value. I think this particular sizing is value heavy
blocking 2 of the ~3 A5 combos is a pretty bad thing here, too. our flop sizing doesn't leave villain with much air on this turn card (how many A high hands get here?), likely requiring them to dip into 9T-JJ stuff that surely can't be relied upon.
I would not bet this rainbow flop as to have pot control at same time. Better to use 99 or TT to bet this flop rather than AA-JJ as there is some backdoor straight draw for you to continue the turn.
If flop get called with this bet size (2/3 pot), you could put your component at 8s, 5s or 7s, 78s, 67s, 56s, 89s etc. To the turn, the villain could use his range advantage to float you. I would call with AA and fold KK QQ JJ. Just to ensure not being exploit at this point. For river, the villain may stop his bluff since you could also have A6s in your range.
