Just read your review. I haven't read the book but I agree that to be a successful poker play you don't need to "show your work" as they used to say in school. If you memorize the situational odds
, that's probably good enough.
I'm kind of a wannabe math nerd so I like to think about this stuff though. I agree that these kinds of books are probably not good for beginner's necessarily, being that the thinking is so thick.
However, I can see some value of understanding the roots of why the odds are what they are. "Killer Poker by the Numbers" is another book like this. Super heavy in math (actually pretty fun read if you're a math junky, as there are many problems to work out at the end of each chapter).
