Go and Go-Moku

I agree with the others that this book is not for the beginner, but I have found it quite helpful, as every move shown has a purpose, and you have to work a bit to figure it out. If you enjoy figuring things out for yourself, and are willing to do some work, this is the Go book for you.

As the other reviews say, the bulk of this book is raw lists of moves, with explinations, and complicated variations. You absolutely need a board to follow along. Also, this isn't for the rank beginner.Some things are hard to follow, and it takes time, and it takes patience, and even some thought, but it's worth it. When you force yourself to think about the examples in this book, and really understand them all, you'll find that you have actually learned quite a bit.
