AA in position facing a bet and a reraise on the flop

SB is TAG, UTG is a bad loose aggro. What do I do? I thought about calling or folding (I dont think a raise will be called by a worse hand in this spot), because UTG could be minraising with draws and toppair.

Call, see what happens.

i think i 3bet to 50 here. I can't see him having anything but T9/56.

Laggs raise pairs preflop, so I think 78 is your only worry (which you have a lot of equity against).

i hate this spot. If hes a donkey he probably has you beat

I thought I was probably beat when a decent TAG lead out in a raised multiway pot OOP. But I called as I had a strong hand in position and because the lead could be a bluff/semibluff/toppair and UTG could have anything with his minraise. After I called the action went on to the TAG who pushed allin - both UTG and I folded, I cant see the TAG player making this moving with anything less than twopair or a set.

min re raise, fold if tag pushes?
