The LRR preflop shouldn't bother you. If the SB has AA then he's raising preflop since there are 3 limpers already and he can't count on a raise from you in the BB. Usually this activity is suited connectors trying to gamble and build a big pot. This is an easy preflop cap.

I 3-bet this turn. 2-pair will be a frequent holding for the CO and you have the SB providing good overlay if you are behind KQ.

I might CR this river if I had called the turn raise, thus trapping SB for a bet. Leading isn't the worst play as the river card might scare a passive player into checking behind.
