I'm playing a $1.10 MTT tomorrow. My intention is to win the tournament.
Starting with 10000 chips I am building my stack to 400000 3.5 hours in.

Assuming we play 300 hands in this time frame what are some ways to build this kind of stack? What are the odds of getting AA in 300 hands? I know the odds are 220:1 so does that mean we are likely to get aces once in this time frame?

You have about a 75% chance of getting AA at least once in 300 hands

If you are playing to win, you basically have to play with no fear of losing. Never limp into a pot, always play aggressive, be willing to flip for big chunks of your stack. Be willing to try and buy pots(but don't be foolhardy. If you notice that, being a micro, no one is folding to bluffs, shuft gears and stop bluffing and start playing thinner value).

Getting to and staying at 100bb in the mid parts of the tournament requires aggression and luck.

I do commend you for knowing that there is difference between playing to cash and playing to win.

If you are playing to win, you basically have to play with no fear of losing.

This

Think of this: When stacks are large relative to the blinds, the average player plays too many pots. When stacks get short relative to the blinds, they fold too much.

You do the opposite.

The chance of getting AA doesn't matter. Because everyone else has the same chance of getting AA as you.
This should tell you that 'getting good cards' in-and-of-itself will not be the key to (consistently) building a big stack in a tournament.
Every blue moon you will run hot (but so will everyone else)...so overall playing the monster hands for stacks will not make you a winning player (because everyone else will do that, too)
AA vs KK all-in preflop is nice - but in the long run these hands are just pushing chips around the table and not giving anyone a net profit.

The way to build a big stack is to consistently play better poker than your opponents in the marginal spots. Mostly it comes down to making fewer -and less costly- mistakes.

This directly translates to a strategy: Put your opponents into positions where they can make (preferrably costly) mistakes while trying to avoid these situations yourself. Force decisions.
This means betting more often than you might feel comfortable with (but not blindly so).

Be aware of all the other things besides the cards. Player types, betting patterns, bet sizes, stack sizes, position, ...
Poker is a game of information - and your cards are only a small part of that.

I'm going back to playing solely live tournaments. I am up lifetime over small sample of tournaments.

This is pretty much the strategy I employed in order to win tournaments. With entries of 150 players to 20 players it is the same deal. Players play way too tight at final tables around bubbles and what not. Me I would rather risk finishing 4th in order to finish 1st. Other players on the other hand want to finish in the money and fold QQ 20BB deep and show on the bubble while I hold AJo shoving their open bet. They say I'm confident and I don't hesitate when putting all my chips in the pot. That was a one off case. I've had other cases where someone has folded AK with 25BBs. I'm never folding AK or QQ in those spots.

Early in these tournaments it's 4-5 players in every pot. Later its back to 1-3 players in every pot or its folded after a opening bet. People have commented that I don't play a hand in the first hour or two before the break and during late rego/re-entry. Usually its only 1 re-entry tournaments I play in. These players probably play 30% of hands if not more. Later I'm playing nearly every hand when its short handed on final tables with 4-7 players and top 3 are usually paid. I just shove every hand because I collect blinds but I'm also hitting hands at the same time and just get called with I have AK vs AQ or AK vs KJ. They say how the **** do I just hit hands like that.

I also got super lucky in a few tournament wins with hitting trips with 99 vs TT hitting a 9 and I also get players to fold 99 30BB deep against a open by a lag and me coming in with a shove on the SB with A6o and then the BB goes into the tank with 99 and folds and the lag folds. I show my A6o and the guy with 99s is pissed off. The lag raises with hands like JTs,98s A5s 66 and will probably fold 3 of those of hands if not all of them with the info he got on me. He will probably call with 66 next time though and so will the BB call with 99. Both these guys are winners and are the better two players in the game. I basically want this loose image and want calls on the final table because I just seem to hit hands on final tables. When I don't I'm basically hoping to get lucky if they got hands 10BB deep but most of the opponents don't have good hands and fold some decent hands as well. Certain players won't fold decent hands against me but I'm hoping to run good against them either by hitting good hands or sucking out postflop when all in pre. I once had T2o and shoved 8BB deep 4 handed and ran into AA and hit TT2 on the flop. Went on to win that tournament because everyone else was 1-5bb deep and I had nearly 20BB 3 handed. if it didn't happen I might not have won that tournament. Sometimes you make your own luck.

I'm after tournament wins not really the money. The money is good but winning tournaments is my buzz. Online doesn't really give me the same buzz as winning a live tournament.

I wonder if it's actually the case that other players understand ICM

Some do. Some are online streamers who i have bluffed of hands deep in tournaments around bubbles. These guys make profit in the online games and are decent in bigger live tournaments. ($2000-$500 buyins). Played them in smaller buy-in live mtts with decent pricepools and I won that particular tournament where one of them of hand on the flop with a check-raise all-in bluff right on the bubble with air. Winning 24+BB in spots like that moving your stack from 35BB to 59BB is a good thing.

I don't have much clue about ICM never really studied it because my goal ain't profit. One of these guys even says on his stream his goal ain't the win the tournament but to make profit. this guy i bluffed above. he's a member on this forum too but don't post much.

i think ICM is important to know if your goal is make money but to actually win tournaments knowing the concept in general might enable you to collect pots in spots which you give more fire power meaning more chips to play with. Double a stack of 30bb gives you 60BB double a stack of 40BB gives you 20BB more.

that 20BB gives you a better shot of winning. I'm willing to risk it in spots and even sometimes you hit when you get caught with your pants down. I like to have a Out when i do it like having a Ace up my sleeve like i did on that flop where i shoved with air. if he had a K and called on the flop with top pair good kicker and didn't have a Ace I still got a chance. I also still got a chance with a backdoor straight draw as well. Right on the bubble he might fold a hand like KT as well to a check/raise all in there for basically all of his chips. he doesn't want a stack of less than 5bb on the bubble.
