In another review about a book by the same author, I remarked that reading his books is like chewing sawdust. This basic fact has not changed. However, I now maintain that Bill Root has written the best books on learning the game in all its aspects.
This book is not about plain point ranges as another reader has already claimed; the book is logical, methodical, clear, but there is a catch: this is to be read like a text book; I have taken notes, underlined, and made crib sheets out of it. If you slow down enough your reading speed and do not read it casually like a novel, you will be amptly rewarded.
An example of the terseness of this book is that the headings in this book need to be read and fully understood before reading the respective sections; most of us tend to skip the headings, don't we?
Before I have used this terseness as a con in Root's books, but I have come to realise that this is the best possible format: no distractions, just pure essence.
I am tired of these books that are full of anectodes, pretend to ease you into the point they are trying to make, and then ... KABOOM, here is the point as dry as ever.
Root's books have the guts to be pure bridge, no filler, no gimmicks, JUST EXACTLY WHAT YOU NEED TO KNOW WITH NO HOLDING BACK OR TRYING TO SPREAD THE INFORMATION OVER SEVERAL BOOKS.
Root headed out to teach with no compromise, but following a standard of completeness and clarity.
It took me quite a time to realise his sense of integrity and charisma, but I did. I am sure that any absolute beginner will initially resist buying his books, but he or she will inexorably gravitate to them and appreciate their wealth of information.
It is this wealth that will make you go through them slowly; the other authors have spoiled you and have put the emphasis on easy reading.
A page by Root is worth easily 20 by the other authors.
