QQ in 3bet pot with coldcallers--.5/1

[jc1418]

Villain in this hand is loose and pretty passive, I have no stats and little history with him. I have been aggressive, built up my stack a bit, but have not done anything crazy, just playin solid I guess.

UTG 256
Hero 122
CO 75
Btn 90
SB 150
Villain (bb)115

Hero dealt QhQd

utg raises to 3, hero raises to 9, co folds, btn folds, sb calls, bb calls, utg calls

Flop: Jc Jd 7h
pot: 36
sb checks, villain bets 17, utg folds, hero calls, sb folds
(I just called flop b/c sb was tight and his coldcalling range worried me)

turn: 8c
pot 70
villain bets 50, hero goes all in, bb calls

Do you guys play the flop any differently?
does villains lead in a multiway 3bet pot worry you or would you put him on a weak holding without any reads?
