Hero??

After the first round of betting, I have CO on AK,AQs,JJ+ for 3b the min-open of UTG+1. I'd put SB on 22+,AJs,AQ+,KQs for flatting the 3b.

Q1: flat CO's 3b, 4b or fold? I thought for a while and elected to flat and shut down on any A or K flop, although I don't like playing a big pair OOP in a multiway pot.

After UTG+1 goes all-in, I'd say CO's range for calling is JJ+,AK. He needs a lot of strength I think to call this with two players who could still call after him.

Q2: what now? call the all-in, fold or raise?
Q3: if calling the all-in, what's the plan for the flop?
