The line in hand 1 only folds out complete bluffs imo. He's not going to hero-fold pretty much any pair that he bet the turn with. Check-raising the turn puts him in a much more difficult spot. If he calls with a marginal hand he knows he might be facing another bet on the river. If he is on a complete bluff he needs to risk his stack to win, but he also has to worry about semi-bluffs that will call that might be better than him.
I'd c/r a gutshot there if he's a floatmonkey, but I'd be careful. There are manicas who will never give up.

In the AA hand I don''t think you thought this through.
Betting is clearly +EV - he'll peel with most pairs and some broadways and prolly some connectors.
I still never know if the last part of the stats is 3b or AF - please dump the AF and add 3b or 3b vs steal - that will change the ranges a lot.
Checking is 0EV, gives them free draws and makes it more complicated to play because you look very weak, and you basically have to stack off to aggression now.
If the villain isn't going to pound on weakness, then I'd still bet the flop. And if he is, then I'd also bet the flop.
