PS $3.25 45-man MTT - A9o in SB 7-handed - somebody stop me pls

[2Fast]

2 limpers to me in SB so I raise with A9o - then follow up OOP with a C-bet and when 3rd diamond hits on turn just shove with nut flush draw but ace high - should I have shut down on the turn or was firing the 2nd barrel ok here? Is leading out for 1/3 my stack OOP versus 2 callers too aggressive given I didn't hit flop at all?

in a 3.25 no way anyone folds with half their stack already committed in a blind v blind situation ... did he show 56o?

just shove the flop if this is where you are going
