Two AA hands - lots of action - too aggressive?

[Jonny Melon]

Hand 1 is fine. On the initial river raise: UTG looks most like a busted draw (on the initial raise), so no point in going for the overcall. Your read was 2 pair, his likeliest holding, so you raise. Your opponent likely puts you on AK, not AA, here, based on how the hand played out. Their most likely holding, then, is KJ, and they think they are ahead on the river. Would MP3 really limp (and not limp-reraise) w/ AA or JJ? Would they play 77 like this on the flop? A 3 is very unlikely as well. This is a good raise, more often than not. Just call the 3-bet as you did.

Here is something you want to consider on hand 2, which I think you realize you misplayed. Imagine now that you raise pre-flop in the next hand, and you again are HU with the same player. The flop totally misses you. Good luck betting out and picking it up unconstested.
