Query: Not learning any math here

As other reviewers have said, this book is verbose and teaches little math. Sometimes in Sunday papers, I read these accounts of chess matches. These can be entertaining, even w/o an understanding of the chess moves. This book is like those columns. It's describes math, but doesn't teach it. In fact, the few pages devoted to actual math are in a small font & are quite terse.
