I'd lead out with a weakish "scared" c-bet (a lill less than half the pot.. you want your opponent to believe he has fold-equity), praying for a raise.. if called or raised, I would call, and make a "fake lock-bet" when/if the board 2 flush on turn.. maybe you'll get him to push on you... if you are lucky...
If he has missed (probably he has) you'd get no action by playing strong.. villain will just move on... try luring him into the darkness... checking could also be an option here, but it really comes down to your opponent and his style of play I think.. you have a well disguised hand.. let your opponent think he can take this down somehow... or try at least [img]/images/graemlins/smile.gif[/img]
