Flop: 3 [img]/images/graemlins/club.gif[/img]Q [img]/images/graemlins/club.gif[/img]8 [img]/images/graemlins/diamond.gif[/img] Villain bets 330. Hero?

Only hand I played with villain; I raised preflop he called in position and folded to my cbet. A pot sized bet seems to be his standard over a few hands. I think flat calling is out of the question. Is this a clear fold or is a raise okay in this situation. Thoughts?
