I'd almost always call the flop/raise the turn here. It just looks so strong against a good opponent. Of course, if he's good enough to 3rd level on that and call weak when you make the delayed bluff, I guess you might want to play it different. Do you really 3-bet the nut flush on the flop though? I can't remember ever doing that.

As much as you'd like to maximize your equity if you get caught bluffing with a set, I think I like waiting for the turn here just because it brings your fold equity up so much.

As played, call. You're so short that you only have to pick off a semi-bluff once in a blue moon to make it worth calling. I think an unpredictable good LAG opponent will put you on the naked K enough with this line to make calling with top set worthwhile.
