Fold, fold, fold pre. This flat is pretty much always going to be bad with respect to stack sizes: flatting a hefty 4-bet 56bb deep with KT is an extremely rare for it to be correct, and I doubt it was despite the aggressive dynamic. It's going to be really difficult to play OOP and If he's 4betting a lot (like with his low Ax and stuff), I think flatting the initial raise is going to be much better. Don't fall into the trap of thinking that just because your opponent is aggressive with 3betting/bluffing, that means that YOU have to 3bet wider in response. That's not always the correct adjustment at all.\\The turn jam is trying to fold out too narrow of a range: KQ/KJ/maybe pps 88 or less, hands like that. I think he pretty rarely folds 9x or anything like that. Yes, it's true that it does better vs his air, but it obviously does a lot worse against all his made hands. It's also a flop where you'd really expect him to c-bet with his junk - not cbetting is almost an alarm bell from an aggressive player. If you think there's enough air in his range I would call the turn small bet rather than jam over, because there's not enough stuff that you lose to and is folding to a jam.But really, fold pre :)
