SNG 10+1 hand

Here's a hand that I played just now:

Party Poker No-Limit Hold'em Tourney, Big Blind is t50 (8 handed) converter

Button (t435)
SB (t945)
BB (t1075)
UTG (t1960)
UTG+1 (t1190)
MP1 (t1570)
Hero (t625)
CO (t200)

Preflop: Hero is MP2 with As, 7h.
3 folds, Hero raises to t150, 3 folds, Button goes all-in for t435, folded around to Hero who...

So what do I do?

The pot size is t660, and I have to decide if I should call t285. My pot odds are 2.315 to 1.

If he has KK through 88, I need 2.5 to 1. If he has AA I need something like 13 to 1, however with me having an A, the AA is less likely. If he has 77 I need 2.33 to 1. If he has me dominated with AK-A8, I need 2.75 to 1. If I have him dominated with A6-A2, I'm a 1.6 to 1 favourite. Finally, if he has 22 through 66, I need 1.3 to 1.

I think this is a pretty borderline decision. If he went all-in for only t300, I think this is a clear call. The question is does 22-66 happen often enough to make up for the insufficient odds that I'm getting for a 2.5 to 1 or 2.75 to 1. I think not.

I should have folded.

Instead I called, he showed QQ and I took it down when I hit my A. Poker is a mean game.
