My BR has been doing pretty well lately because I have been on a massive heater. I decided to chase a fish up at 100nl and this hand happened.

Villain in the hand is no the fish, he is running 20/15/2 with a decent amount of aggression in late position. I have 3 bet him probably about 2 times in 60 hands and he has folded every single time. To be honest at the time he seemed kind of nitty. Then this happens.
