Little low-stakes SnG. Big stack has been fairly loose. Got his huge stack in 3-way all-in with top set.
I don't think he has to have T9. Even if he has it, I'm not that much of a dog.
Of course he could have a set also. But considering my holding it's not too likely. Or is that a misconception in Omaha?
Anyway, my guess is it should have been an all-in move.
Or fold preflop maybe.

Stack sizes:
UTG: t6205
Hero: t1210
Button: t650
SB: t3130
BB: t2305

Pre-flop: (5 players) Hero is CO with Q 8 9 J
UTG calls t120 (pot was t180), Hero calls t120 (pot was t300), Button calls t120 (pot was t420), SB calls t60 (pot was t540), BB checks.

Flop: Q J 8 (t600, 5 players)
SB checks, BB checks, UTG bets t480, Hero ???

Since you are pretty short and can by no means coast into the money (I assume it pays top 3), I would probably raise it up preflop and get all in on most flops. As played, I think this is a fold. You are never in decent shape here except against AK10x, which is still doing fine. I think this is 109xy most of the time though due to his big bet into 5 players and his preflop limp which could mean a rundown hand like 10976.
