Villain in this hand is running something like 60/32/7 but only over 53 hands. He has been 3 betting me a lot recently. When he first started he was always min 3 betting but I was running him over and he has adapted his 3 bet size to mine. Not sure if that means anything. He is very aggressive and fires pot sized bets like its his job.

This is all off memory, I'm going to try to make it as accurate as possible.
