I would quietly call here. If he has a jack that saves you your money if you miss your flush on turn, while giving you a chance to bust him. If he has no jack, he will check the turn in most cases and you decide either you apply pressure on him representing a jack or draw to your flush on the river. I would take a free card here. Near the bubble I dont want to risk significant amount of my stack, while looking for (relatively) cheap situations to double up or bust somebody.
