What would a bonafide pro do in this scenario?

Hero 100 BB effective. Full table $1-$2 NLH online cash game. UTG +2 raises pre-flop to $6, Hero in hijack with KK reraises to $22 button 3-bets to $45 and initial opener folds. Hero calls. Flop is 986 with two hearts. Hero checks and 3-bettor shoves putting Hero all in. Hero hasn't developed a profile on the villain yet.

Button hit a set in my mind so what to do?

You still winning vs TT JJ QQ AQ AK

But why you don't 5 bet shove pre flop? if they had aces, congratz for him, and go next hand...

A set doesn't make sense because the button wouldn't 3-bet a middle pair. generally. V had the only winning pair. Bummer! I guess you can only fold to the shove if you've been closely watching the player.
