Oversize raises

I won't bother with all the stack sizes and such, i'm looking for overall advice in generally similar situations.

Basically still 9 handed, $20 Party SNG, 10/15 blinds, even stacks. I am BB with AQs, folds around to the button, who makes it 150 to go. Fold it this early out of position for the over raise? I can't imagine pushing, but I hate to just call and damn I hate to fold. Seems like the call is the best of annoying choices, but seems like trouble.

Essentially, what assumptions do you make when someone suddenly puts in 8x bb behind no raises, and what kind of hand do you need to play with?

he's probably a donk. fold- waaaaaay too early. make a note he overbets.

I push AK and probably JJ+.

I shove. Man if I get a sweet opportunity to let people know from the getgo that they can't mess with me, I'm all over it.

I think you're likely against a donkey who's raising with a small pocket pair (do you really want to race?- in my experience he'll look you up with 44) or a donkey who's raising with a big pocket pair. Just let the tiny BB go.
