Help i am from the mean PLO streets and am starting to dabble in MTTs. Im a young kid with an aggro image and the villain is a MTT pro who plays to a lot of MTTs and is opening wide. Villain was the chip leader at the table. This is the second time i 3bet the villain from the button. We are on beginning of Day 2. I couldn't care less about min cashing.

BB 2400
Hero 105k
Villain 150k

Villain opens 5200 from HJ. I 3bet black AK to 14k. Villain flats. Flop 636 two hearts . Villain checks. Me 15k. Villain check raises to 32k? I have 76k behind. WTF?
