I can definitly say, Thinkitthrough is one of the greatest minds of this forum!
He teached me playing heads up by using his mindmodel that really helped me for improfing my game.
The most important i learned that there is no unorthodox/orthodox way of playing poker, only -EV and +EV.
Whatīs cool is that he has an overall model that he can teach you that gives you new motivation but also great success. I didnīt had any motivation to play a year ago and thought that i already reached the top of what my talents and mind can give me. After the coaching i saw that there is still so fkn damn room for progress and development! Also i was destroying the 2k NL games.
What sometimes is crazy is that he sees some things very extreme and really does anything for stopping it. So if you have a bad habit like making cool looking herocalls that destroy your winrate, you will have lots of fun with him. Donīt punch him!
