Top positive review
One of the rare Go books filled with puzzles
Reviewed in the United States on June 21, 2013
One star removed for quite a few errors in the diagrams, which for advanced players can be seen clearly, but for beginner and intermediate, will subtract from the book's value and add time and frustration to the solution process. It depends on your level and attitude; most of the errors are trivial and can be spotted quickly in context which you might see positively as another level of challenge, but if you're struggling with subtle concepts like Ko, it can be really annoying.
That said, it is rare and wonderful to have a book packed with go puzzles at all! There are literally hundreds of chess puzzle teaser books that help us learn and grow, but surprisingly few go texts that use as many diagrams and teaching teasers/puzzles as this great little book does. The web has some sites, and even some training puzzle sites, but this volume is much more advanced than those, which are typically in the 20 to 30 range (the lower you go in Kyu the higher you're rated, until you hit Dan). This book is much closer to first Dan as you get into it-- NOT really for "new" beginners.
In fact, beginners who have just learned to connect pieces for safety will not understand where and why the author is promoting separation patterns. These are really there for pattern recognition and preparation for things like establishing eyes and life (which the author wrongly states is not important in chess (pattern recognition)- it is), but certainly is right that it is MUCH more important in Go. I guess his point is that there is more pattern recognition in chess and creation in go. Connecting is important for protection, but 1, 2 and 3 spaces are shown to be great territory stake outs, as long as you quickly surround enemy incursions in those spaces.
I got this book on Kindle, and there are no e-reader issues like with some math formulas (but see below), shows up the same as the print version and the cloud version on my laptop. Very fine little book, rare in number and depth of puzzles, highly recommended to improve your game if you're getting to 10K and lower, as long as you can get around the mistakes.
IMPORTANT TIP: If you're struggling to decide whether to get print or Kindle, remember that in a puzzle book, you're looking back and forth between the description and diagrams constantly. As you know, that means you'll be double clicking a lot, back and forth, on Kindle. If you're Kindle nimble and young, no biggie. If that annoys you (and it might well if you're relatively new to advanced concepts, or you're old like me and forget what you read by the time you get back to the diagram ;=)), go for the print version. Of course cloud comes with Kindle, and those issues don't apply if you've got a large PC or TV screen-- much larger than the printed book! Just didn't want you disappointed at the Kindle back and forth, I have the biggest Fire, and still have to double tap with these old eyes.
