That is one of the issues. Sadly enough AA is not the great a hand early on because you will get a lot of people calling. Especially if you raise half your stack. They see dollar signs.
Now granted your odds
of losing against 2 other hands are better then when you get 6 people calling. But, you still lost.
Sometimes a lesser bet works to chase off these kind of people than a large one.
Odd but they think the opposite of other poker players. The bigger the pot the more they want to gamble on a hand. Even if it is junk.
Plus you seem to want to read these people as having good hands when they call that big a bet. Early on in the tourney you really can't do this. You have to assume they could have anything. Because they likely will.
Frankly a 2-4x pot bet is sufficient. If junk calls and flops a monster they will likely let you know. He would have likely gone all in wanting to get someone to double or triple him up. AAs can kill you if you don't read when it is time to let them go.
