When do you pass up +EV for a better spot in a MTT?

If you know the player after you has 4 [img]/images/graemlins/club.gif[/img]5 [img]/images/graemlins/club.gif[/img] and will call your all-in no matter what, do you go all in w/ A [img]/images/graemlins/spade.gif[/img]Q [img]/images/graemlins/spade.gif[/img]? I know it's +EV, but if the player is playing this poorly are there better spots?

This happened to me in a RL tourny. Guy would expose his cards, call w/ any two all the way down, etc..

The blinds were on an insane scale, and went up by factors of 3 to 5, so my stack is small compared to the blinds even though I've chipped up a little.

Blinds 25/50, I had about 275. This is the fourth level, and they started at 1/2. I was 60/40 here, would it be realistic to find a better spot, or is this as good as it will get? I Pushed, but a freind pointed out that I had no FE against this guy so I should have waited for a better hand. I didn't think I'd survive long enough to find better than AQs.

What do y'all think?
