And he's gonna check KQ twice, even when a flush draw shows up on the turn, when there is a huge call station?

There is very little chance he has any straight here. While you will occasionally run into shortstackers that make retarded slowplays, you can pretty much rule out KQ and Q8 given the double check so the only real concern is that he is currently chopping with some kind of redraw. It's much more likely that he has a set/two pair/air.
