100NL - OESD on Turn after c-bet called on the Flop

[patchdiaz]

This has happened to me a lot and I don't know if it's better to bet or check trying to catch any possible out. I'm not asking about this particular hand, I would like to know what you do in this cases. You c-bet the flop and then the turn card made you a draw. Bet? Check? Villain dependent?
