good draw, OOP, multiway action

[liquid]

IMO, UTG is now my #1 candidate for a flush draw (his line seems common among unknown short-stacked foes I see); CO obviously has no redraws; and B1 is a mystery but likely has only one of the three main possibilities (straight, flush draw, lower set).

I thought it was an easy push at this point, if for nothing else but to build a good sidepot if UTG has a better flush draw. CO and B1 both called. Foes' hands:

UTG: 7[img]/images/graemlins/spade.gif[/img] 9[img]/images/graemlins/diamond.gif[/img] 5[img]/images/graemlins/club.gif[/img] 3[img]/images/graemlins/diamond.gif[/img] (??)
CO: A[img]/images/graemlins/heart.gif[/img] A[img]/images/graemlins/diamond.gif[/img] 6[img]/images/graemlins/club.gif[/img] 5[img]/images/graemlins/diamond.gif[/img]
B1: 6[img]/images/graemlins/diamond.gif[/img] T[img]/images/graemlins/spade.gif[/img] A[img]/images/graemlins/spade.gif[/img] 5[img]/images/graemlins/spade.gif[/img]

Side note: Hands like this one are why I [img]/images/graemlins/heart.gif[/img] PLO (even though the holdings here turned out to be less interesting than I expected). Sundry draws, lots of information, and knotty puzzles to process. Decisions matter.
