ITM flush draw in a 20 person SNG - Push it?

[chekraze]

$6 party SNG with 20 players and now down to this. Villain had been an active raiser but mostly on the button. With him being in the SB I had trouble completely giving him credit for the ace and felt pushing this might give good results in either a flush or fold. As played, is there a standard play here that I should know about? And also, is this a preflop fold for many people?
