Played about 200 hands or so with villain, he seems quite passive pre-flop but has c/raised fairly often vs cbets when I've been stealing his blinds on dry boards like this.

If he checks the turn (which I expect him to do often if he just has air) I can bet profitably I think, plus there are lots of scary runouts and I expect his c/raises to be more polarised than thin value (due to his passive tendencies in other spots) so I doubt he's c/raising A4 or 88 etc, or many Tx (if any).

I bet as planned and he double c/raises? What do you have buddy? Seems like a pretty good combo to bluff shove as I have at least 8 outs when called and his line is a head-scratcher.
