When I play AA, I usually bet between 4 to 5 the BB to limit the field (don't offer good pot
odds to call), I never slowplay aces, they will get cracked if the flop is appealing to too many other hands.
Raising will 'usually' get you to two callers at most (ideally you want to be heads up), and then you have to feel out if you have the best hand from there. I can't tell you how many times I see a flop that is all same suit and the AA then shoves (or tries to
bluff) (feeling way too overconfident because they think AA is invisible) only to get called by a flush or someone chasing some other straight draw.
Board texture is everything, playing after the flop is where the real skill in poker comes into play. (and ironically many hands do not even make it to showdown if playing against skilled players)
I think shoving AA is pretty silly (early) in tournament poker, considering the objective is to survive the tournament. I would shove AA later in a tournament as the blinds and antes will eliminate you if you don't make bolder moves, but early in a tournament is just
gambling in my opinion. There are factors to consider if I shove AA, such as stacks, how many are in the pot, player tendencies etc, how big are the blinds/antes.
Many will call with something like AK suited, KK, QQ and even JJ (which is super risky)...people even call any pocket pair lol. So trips are very possible if you shove AA against players that overvalue their whole card or chase their flush or straight draws.

I do however alter my bet sizing so people can't put me on exact hands with strength. I will sometimes raise 5bb even 6bb with garbage hands just because I have a feel I can take the pot right there with garbage hands against certain players
Which is not even a real bluff, because a real bluff has to tell some kind of story or you have at least some chance of hitting a hand lol
My method could be incorrect, but I am happy with those results instead of simply shoving with AA like I am playing bingo or the lottery lol.
