if i had AA or KK, i'd call you. now if you only raised.... I'd have to think about it more. you haven't shown any aggression within the hand, and its unlikely a hand that would call a 3 bet would have a 2 (save pocket 2s perhaps) or would hit the straight draw.
That leaves monsters and sets for you to worry about.
Note HJ has been better 1/4 pots. Assuming this isn't just what he normally does, it lends to strength. 1/4 pots won't scare away anyone who has a decent hand.
So good chance you are beat. I would do the full pot bet if bluffing
, but this isn't a hand where i would try it. the 3 bet at the beginning, thin though it was, narrowed everyone's range to the point that the wetness of this board isn't a factor. I find it tends to work better if he has to sweat thinking they you have a straight or a flush rather than worrying about a set. Sets are disguised, that's their advantage when you have them, but it makes them harder to represent in a bluff.
My 2 cents, but i'm still pretty bad.
