A J offsuit leak

[S. L.]

raise preflop, raise flop - it is for value i think, there are three people in the pot, you dont think they all have straights allready? no; so, you have TPTK, raise while you have the best hand.
on the turn you can call.
on the river, call one, o/w fold UI.

as for your reasoning, i don't think you have 9 flush outs, because if you do, you probably still have the best hand (ps- i'm not sure if that's legit logic when counting outs) - unless ofcourse utg1 slowplayed a made straight on the flop (don't think so).
