Preflop
Standard raise. I also use 3BB in the first blind level of 75BB SnGs. From the second blind level I go to 2,5BB.
Flop
This is a great flop for aces, because its quite likely, someone can have top pair, and its highly unlikely, someone can have two pair. Of course if they are fish, anything is possible, but if someone can have Q7 or Q4, then they can also have Q5, Q6, Q8 and Q9, and they are likely taking those top pair bad kicker hands way to far. So even though we are somewhat deep here and against two opponents, I am willing to play for stacks with AA, unless the board runs out unfavourable.
For that reason I like your decision to raise. I dont particular love the sizing though. You min-raised, which let BTN get away easily from any marginal hands, and it gave BB 4:1 on a call. If he had a flushdraw, this is correct odds to draw even to a single card, and you want him to make a mistake, if he continue.
So I would go larger here, which also makes it look more like, you could be bluffing. Spend a few seconds pretending, you are thinking about it, and then make it 400 chips to go. That will create a pot of roughly 1.000, if he call, and then you can just shove the rest in on a clean turn card. This is a great line, if he has a draw, because then he is paying you on the flop, and he will be forced to fold on the turn.
It also helps you create a "maniac" or "bully" image, which can be beneficial later in the tournament, even if you dont get action now. So avoid those cute little min-raises and dont be scared to play fast, when you almost certainly have the best hand. Yeah someone could have 44 or 77, but its much more likely, they dont, and we cant live in constant fear of those (set) monsters under the bed.
Turn
Another pretty good card for you. None of the draws completed, now there are only 4 combos of flopped sets (because QQ 3-bet pre), and if he somehow had Q7, now you beat that hand as well. As played I like your bet and sizing. You made it a 3 street hand, and this sizing sets it up perfectly for a river shove.
River
Worst possible card and action, and as a default I would fold. Its possible, that he could be bluffing with a busted draw, but you have shown a lot of strength in the hand, and you could very easily have a Q, in which case bluffing into that would be totally suicidal. You dont have any info on the guy, and in my experience, as a population read in games like this, he is not bluffing 30% of the time. So I would find a bucket, puke, and then lay down those aces. Being able to make a fold like this is part of, what separate the winners and losers in the micros.
