It has 4 1/2 stars. I was lucky that my school still has those old Chernev's chess books; strange that it has more old than new ones (???, butget cuts). Anyway these Chernev's books are in high quality. He and Reinfeld were the two most chess teachers and authors. Reinfeld, as I recalled from memory, was a stronger player but Chernev's books are always better. When they combined their work, we as benefitors have the best of both worlds. This book has lots of facts, many valuable stoties, games, and puzzles. At the time when annotation was not deliberately shared, this book was good. Now we expect more from the authors to share their thoughts and secrets. A little more work then it can get a 5-star rating.
