This book is a follow-up to Constructive Bidding 401, which introduced the teamwork and structure needed for a complete bidding system. Together, the two books provide advancing partnerships a complete and consistent framework in the form of a bidding system for competition in stratified tournaments at higher levels. Book Two begins with opener's rebids and progresses to slam bidding. The book finishes a discussion on the strategy required for matchpoints and IMPs. Two Over One bids and Forcing 1NT are a small component of this bidding system. Of greater importance is the need to define and manage a broad range of bidding situations in a predictable fashion. While discussion on Two Over One is complete, it is a small portion of the total content and the focus is on a complete system. Patterned after a college text book, concepts are presented, explained and then detailed in a tabular format. A summary and quiz following each major section develops the reader's understanding. The quizzes in both books contain more than 450 question and answers.
