PP 10/20 AQ TPTK v. Button 3 bet (Xpost forom Small)

[StacysMom]

So after seeing the last peak of my bank roll $6000 and 50K hands ago, I'm beggining to question every part of my game. So I am resolving to post quite a few hands, even ones that may seem rather simple, as I no longer am sure I'm playing winning poker.

Villian is a regular grindier. I have 1k+hands on him at 16/10/2
