I disagree with folding preflop here. Your getting 10-1 to call. A8 isn't a terrible limping pot hand. You have to keep relative strength in mind. The only possible hand that could dominate you here is a limping A9. AT or higher would have raised preflop most likely. One pair aces on the flop here gives you best hand a lot.

You limped with fantastic pot odds, hit two pair, and then got smooth called by trips. It's a bad beat. Don't stop limping with fantastic pot odds holding a good limping pot hand.

Even though it is risky and generally considered incorrect, sometimes I would actually RAISE this preflop on a passive table. I don't recommend it for everyone. The reason I do this is because I feel I have best hand at the moment regardless of my position. I would raise it 4-5x to trim the fat. That's just me. I enjoy the mental postflop game. Conditions would have to be perfect for me to raise this vulnerable hand however.

For most people I say limp it and attack weakness postflop when an ace pops. It's just very hairy 7 handed. I feel very uncomfortable multi handed after the flop.
