K-K in Big Bling with UTG raise

[lozen]

This weekend I plan on figuring out the hnad converter. So I can properly pots hands for advice.

I am in the Big Blind (5/10 Party) when UTG raises with a mid caller so I 3 bet and everyone calls. Board hits with an ace and a rainbow flop. How do you hnadle this do you bet out and if he raises let it go? Or check it and reraise him to see if he 3 bets it? Had no info on the guy

I also wonder what the correct play is in this situation. Usually I'll lead out on the flop and see what happens. If I get raised on the flop I'm probably checkfolding the turn unless I know the raiser to be a total maniac. If I just get called on the flop by one or both of them I have a tendency to check/call it to a showdown, but I usually wind up losing to A-x so I'm not sure that's actually the right play. Either way, I'm only leading out again on the turn if it's a K or another A.
