1/2 - set on 3-flush turn and blank river

Villain is one of the best 1/2 regs imo. Running 24/18/2.3 over a lot of hands, 3bets MP 4%, folds to cbets 50%, raises cbets 12%. He probably thinks I'm super stationy because I've made a couple of bad hero calls vs. him. He might also think I'm aggro (which I am) as he has slowplayed me a couple of times, although not on boards this drawy.
