I've always played poker mostly by "feel" and have been pretty good, but knew if I ever wanted to become great that I had to learn more of the mathematics involved and incorporate them into my game. So I decided to buy a book that dealt specifically with the math involved in poker, and although there were multiple choices, I went with this one based purely off the fact that it was authored by Collin Moshman and Douglas Zare. I've purchased both of Collin's other poker books, and I credit the majority of my poker success from what I've learned in those teachings and I highly recommend them. As do I this newest book as well.
Collin deals with everything I've heard about but never understood; such as EV, variance, bankroll management, hand ranges, Nash equilibrium and much more. Now my game is now more advanced and my understanding of poker is deeper than ever. There's a reason so many young internet based poker players are crushing live and online; because they took the time to learn all these strategies and concepts and incorporate them everytime they sit at the table. Whether you consider yourself a novice or an expert, Collin and Douglas will help strengthen your foundation in an easy to understand way, and you will be amazed at how different and clearly you look at the game of poker afterwards. And the confidence you'll aquire simply from posessing and utilizing these tools correctly is priceless.
If you want to invest in your future and increase your winrate then trust me, YOU WANT THIS BOOK!!
