there isn't even a flopped flush draw. As Fnord says, it's crazy how much people worry about flush draws. Presence of a flush draw should only alter your line a small amount, especially out of position, and in this particular case it should have no influence whatsoever since it is a backdoor draw. If this opponent wasn't a tool, he would have priced you out of this pot on the turn. You're out of position, you have big implied odds if he's got a betable/raisable hand at the turn, and you can't stand a real raise if you bet. So c/c.
