MTT learning experience

[swede0530]

This seems like a situation that comes up quite a bit. I'm looking to learn and get some opinions.

Paradise Pina MTT approximately 800 players ($5 buy-in, no rb or ao's)

Bubble at 90 (money back 70 - 90 and increments upwards from there. Win pays about 900)

Blinds 400/800, ante 50
Stack size ~8000T, slightly below average
Tournament point, just before second break, blinds to 600/1200 after break, antes up to 75 also.
No reads as I was just moved to the table about one orbit previous.

I'm under the gun and get AJx

Raise to 2400T hoping for blinds and ante steal or a reckless call.
Slightly smaller stack in the CO goes all in.
I think a bit and call.

CO shows AA and I take a huge hit (down to 650T) and am out in 106th the next hand.

Hindsight seems to indicate a fold pre-flop UTG but......
