The content of this book is very informative and helpful. It focuses on specific rules of many poker variations and some statistics to go with them. There is no shortage of calculated odds tables in this book for you to try to memorize. However, John Scarne needs to get his money at the poker tables because his writing struggles. You will not be fond of this man after your first 15 minutes of reading. To get through this book, you must have alot of determination; you will not be reading it for fun. Perhaps the toughest, most boring read of my life. In my opinion, any improvement on your poker game is not worth the pain of reading this book. There are other great books that will teach you far more efficiently.
