SB checks, Hero bets $7, UTG calls $7, Button folds, SB raises to $30.5, Hero?....snap calls or easy fold? I immediately think that UTG is on some sort of draw, possible NF which makes me think a fold is more appropriate because if I'm calling the all in, I would fully assume UTG would come along.
I can't see much that would make this move with this big field except maybe a SB AA82 something kind of hand.

Any better line to play this hand?

Against unknowns, definitely get it in. Even assuming UTG never folds, you only need 22% equity to be breakeven in the main pot. SB's going to have a set a decent amount, but it's only a 4-way pot so A7 and A6 are strong possibilities too with a wrap being far from out of the question. Likewise, UTG will show up with a wrap or OESD+non-nut FD fairly often as well. I'd say that roughly, it breaks down something like this:

Axxx is good, flush draw is live: 2%
Axxx is good, flush draw dead: 10%
Two pair outs live, flush draw live: 13%
Two pair outs live, flush draw not dead: 7%
Two pair outs dead, flush draw live: 46%
Two pair outs dead, flush draw dead: 22%

That would put your total equity somewhere between 23% and 24% assuming that we're up against a set 68% of the time and the NFD 39%. That is a little closer than I thought, but I've got the random donk factor pretty low here. I think our typical equity's probably a little higher if anything. Obviously, it's close enough that if you know that SB's uber-passive and is going to show up with a set almost always and UTG's a solid TAG that isn't calling with anything weak and will usually be raising with made hands, it can shift the hand to a fold.

Oh, BTW since you have poor visibility here on a coordinated board and would really like to either take the pot down now or get it all-in HU on the flop, you should really be potting it the first time around. You're not going to be able to fold anyway, all the smaller bet does is make it easier for draws to play perfectly against you.

The problem you have is that you are representing AA and sb is still looking to get it in - the most likely hand for him to have is AA himself, or possibly a strong wrap + flush draw. I don't really have much to add to what iggymcfly said - basically it's a close decision.

I don't really like your preflop raise, actually - I understand why you did it, but this hand shows why it is perhaps not so good. AKQT is not really a strong multiway hand, especially not out of position - when you hit a hand with it, it will usually be either the stone cold nuts and you will get no action, or it will be a medium strength draw, like you made in this hand.

I don't understand why I would try to avoid the strategy of raising preflop and flopping the stone nuts in a multiway pot. The only reason I even raised was because the table was becoming more passive and a lot of limping. I raised simply because I wanted to get some more money in the pot and was knowing no one would limp reraise.
