Query: Excellent for the beginner!!

The hallmark of a good teacher is to be able to take an esoteric concept or idea and transform it into an easy to understand, and repeatable, system. Bruce Pandolfini in this book, as well as others, is most successful at this. For a beginning student, this book is a must for the library. I cannot recommend it highly enough.
