It is a huge craft that takes many years to get 'close' to mastering, as you can never truly 'master' poker as there is the element of luck that exists with every hand, of every game. No few books will ever skyrocket anyone to a level of excellence, and for sure not tweaking on the fly will either, even if you run hot for a short time. I do know that some have a natural ability to just pick up on the game instantly, but most get disappointed after they run hot for a period of time, then when they have a major downswing.Most do not resurface, this is why you do not see the same hotshots from the early days still striving to this day. It takes diligent study and practice at the same time. It doesn't just come with reading a few books and winging it from there on out with practice. No, there is value in learning all you can if you want to take the game serious. This book was co-written by James SplitSuit Sweeney and Adam Jones with one goal: to help you play Ace King better EVERY time its dealt to you. If just toying with strategies was all it took, you would be a multi-millionaire like the rest of the high pros lol. Now whether or not that really applies to my game overall (to make money) is definitely subjective, but for me, learning more and having more knowledge of the game is beneficial and of course enjoyable!
