All the basics are covered, with LOTS of examples and non-double dummy problems. It *WILL* take you a while to go through the book, but its well worth it. The book doesn't focus on difficult defense, like the Kelsey Killing Defense at Bridge books. It focuses on general principles, and signaling. A nice touh is a number of different signaling methods are presented at the end of the book. The reader can become familiar with what they may face, and decide what signals to use.
Roots book on Declarer Play is a good beginner/intermediate level book. His book on Conventions is excellent, despite not having all the newest conventions.
