QJo vs TAG 3-bet on a Jh 9s 8h board

I apologize if I posted this in the wrong forum. I wasn't sure if this belonged in the micro limits forum or this one since it was a 6 max table.

Anyhoo, I'm looking for comments on my turn fold, should I have just called down? Raise?

SB is a TAG player while BB is TP PF, and LP on the flop.

Should I have raised PF? I'm fresh to 6 max and have basically been basing my PF strategy on the SSH PF Tight game starting hands (mid, late and blinds).

Flop: (3 SB) 9[img]/images/graemlins/heart.gif[/img], 8[img]/images/graemlins/spade.gif[/img], J[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(3 players)</font>

With TP and a gutshot straight draw, I liked my hand and felt it was good for a raise, however SB's 3-bet into me set off some alarms. I thought he might have flopped the straight here, what else would he 3-bet with?

I'm not sure what BB has here, he could been on a FD or OESD, I chose to fold here fearing I was already beat. Had it been HU I would have called the turn and the river to see a showdown.
