50NL flopped baby flush oop

Villain plays about half his hands and has showed down crap in a couple of losing showdowns so far. He called a big turn shove a few hands ago with a flush draw so he likes to gamble. How would you play it differently knowing that? What would be a good line against a better opponent?
