Live 40-80 Borgata flop decision

[dcb777]

Good 40-80 game last Saturday at the Borgata. I started out running well, but have taken several beats over the past few hours and SB in the hand in question has been whispering to his friend about certain hands I have been involved in. He might think that I am tilting a bit.

UTG limps(bad losing player who is open limping many hands)

I raise UTG+2 with red JJ

SB smooth calls and 3 of us see the flop which comes

KK5 with two hearts. SB leads out and UTG calls. What line do you think is best in this spot and why?

I will post the rest of the hand later, but I want some unbiased feedback about the lines some of you would plan on taking in this hand having just seen the flop.
