2nd nut straight with nut flush redraw

[Fubster]

This hand occurred in a dream I had last night.

Middle stages of a live deepstack PLO tournament. I was just moved to a new table filled with big stacks, I'm sitting on a little less than avg.

UTG limps, folds to me in the CO where I limp along with A[img]/images/graemlins/club.gif[/img] 2[img]/images/graemlins/club.gif[/img] Q[img]/images/graemlins/heart.gif[/img] 8[img]/images/graemlins/heart.gif[/img]. BB raises a little less than pot, UTG calls I call.

Flop comes out J[img]/images/graemlins/club.gif[/img] T[img]/images/graemlins/club.gif[/img] 9[img]/images/graemlins/spade.gif[/img]. UTG leads for pot, which by now is the vast majority of my stack. What do I do?

PS: in my dream we were playing like some weird variant of 13-card omaha or something but since for some reason I remember this hand I kept the basic context and changed it to standard plo.
