I am an old school player, trying to improve my NLHE/MTT game and learn more GTO concepts. I have never been great at studying while I was growing up in school. The main issue I find myself having is not quite knowing what I should be studying and how to go about it. I run some hand histories thru Flopzilla and try to figure out where I may have gone wrong. However, I often find myself unsure if I am even doing that correctly. Any help or guidance towards the correct steps or a plan of study would be much appreciated.
