600nl 3-bet PF JJ on Q-hi flop, 3-way

[Teph]

Effective stacks are 600, (first hand)

Not much history with UTG+1 (< 100 hands in history) Seems weak-tight
A lot of history with SB, he's pretty loose, takes weird lines with draws, tries to be too tricky.

Both villains know me as a lag, probably think I am bad from prior experience.

No Limit Holdem Ring game
Blinds: $3/$6
6 players

Pre-flop: (5 players) Hero is BB with J[img]/images/graemlins/diamond.gif[/img] J[img]/images/graemlins/spade.gif[/img]
UTG calls $6, <font color="red">UTG+1 raises to $21</font>, 1 folds, SB calls $18, <font color="red">Hero raises to $88</font>, UTG folds, UTG+1 Calls $67.00, SB calls $67.00.


Flop: 5[img]/images/graemlins/diamond.gif[/img] Q[img]/images/graemlins/heart.gif[/img] 9[img]/images/graemlins/diamond.gif[/img] ($270, 2 players)
SB checks, <font color="red">Hero ???</font>


Check seems off to me, so if you c-bet how much?

What happens if:

UTG+1 Calls | Pushes (Assume SB folds)
SB Calls | Pushes


Will post Hero's action and rest of hand after some input.

Thanks
