Please don't fold. In fact, you might as well cap it yourself to speed up the action and get to the turn card. Getting 12:1 essentially on a cap (if I count correctly, there were 14BBs PF and there will be 10 more BBs if the 5 opponents call the cap -- which will happen whether you do it or CO/button does), you only need 4 outs immediately to be priced in.

Given that you have 9 outs to a flush, we can still discount the 3d completely since that will clearly fill someone up to bring us to 8 outs -- and if you cut that in half because you may be 50% sure someone has the K-high or Q-high flush draw (KQs, Q9s, whatever), you still have odds to see the turn.
