I have been a professional poker player for almost 10 years. I plav small/mid stakes 6 max NL Hold'em, and my game is best when playing with 40bb. I also suffer from several types of mindset problems (the reason I've been chained to small/mid stakes for so long!) I guess I'm in the way to solve :)
Regarding my approach to poker, I have a somewhat more theoretical path to the game: this is the route I love to explore and what suits best for my game! I love messing around with PioSOLVER, and some of my videos are based on the conclusions I have extracted by using this software.
