If you want to get rid if AA why not raise flop.

I like turn xb as played. If you bet big and get shoved against, it's clear he doesnt have bare aces. What do you think his range is, do you get right odds (how big would you bet)?

River it's not terrible bluffcatch spot, you block straight and sets. I guess exploitative fold is fine though, microplayers dont usually bluff big such spots when you have clear made hand. Most likely holding KK, JJ when you're capped not having straight / AA. T9xx, JTxx, T8xx, lots of missed rundowns out there to bluff with.

This is probably a board that SB smashes a lot. Because he is re-stealing he can have a lot of strong value hands aside from aces that connect really well with this flop. Broadway run downs, KK, JJ etc. I like just folding the flop. As played I think check back turn is good. Villain could be taking a "stack a donk" line and c/r the turn with initiative rather than having to play a river oop. You have the option for a free card and a ton of nut outs so might as well take it.

Hero call river is maybe a good idea though. Villain could also have like a small rundown and three bet as a "gotcha" tactic and just be bluffing because this looks like a board that he should have smashed. With all your blockers and two pair I'd be tempted to look him up.
