Query: Blah

There are two things very wrong with this book. Number one, the binding is horrible. The book started to fall apart right away. Second, the answers in the back of the book are not always correct. Either the best defense isn't played or the best attack isn't carried out. I've worked with tactics books where the problems are checked with a computer and those books are much less of a headache to work with.
