AA laydown

I think you three bet on the flop. How do you know the SB wasn't check-raising with a King? From there if he four bets I check and call to the river due to pot size. If he calls and bets into you on the turn, same thing. If he checks on the turn either check to induce a river bet. Getting check raised on the turn is tough because you'd have to figure that he can beat top pair and thus, probably your AA.

One thing to also is what does he think you have? Do you only raise with only premium hands?
