Need a line check in the BB

[bozlax]

I'm new at the table (less than 10 hands) so no particular reads.

Preflop: Hero is BB with J[img]/images/graemlins/spade.gif[/img], 2[img]/images/graemlins/spade.gif[/img]. CO posts a blind of $1.
UTG calls, MP calls, <font color="#CC3333">CO (poster) raises</font>, Button calls, <font color="#666666">1 fold</font>, Hero calls, <font color="#CC3333">UTG 3-bets</font>, MP calls, CO calls, Button calls, Hero calls.

With 5 players in, I don't think I can let this go for either of these bets. No? Yes?

Flop: (15.50 SB) T[img]/images/graemlins/spade.gif[/img], K[img]/images/graemlins/spade.gif[/img], Q[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(5 players)</font>
Hero checks, <font color="#CC3333">UTG bets</font>, MP calls, CO calls, Button calls, <font color="#CC3333">Hero raises</font>, <font color="#CC3333">UTG 3-bets</font>, MP calls, CO calls, Button folds, Hero ?

A 2-card flush against 3 opponents playing 6-max...I'm pretty happy with the check-raise, and my inclination is to cap for value since I don't think anybody's going anywhere. What do YOU do?
