Review title: Poorly executed Kindle edition Product review: This seems like a pretty decent book for intermediate players. Nevertheless, the Kindle edition is useless. The illustrations are so small on a reader that they are kind of hard to make out, especially if you use your phone to read, e.g. when you are waiting at your child's swim meet. Also, the problems and their solutions are in different parts of the book. I just couldn't use the Kindle edition because there is no good way to flip back and forth between sections. The board diagrams, the solutions and their discussion should be on the same page, otherwise the Kindle edition is useless. Stick to the printed edition.
The answer is:
