Constructive Bidding 401 is the first of two books that provides advancing partnerships with a complete and consistent framework in the form of a bidding system for competition in stratified tournaments at higher levels. This first book emphasizes the importance of working with your partner. Concepts of teamwork from the business world are presented in a bridge context with a number of partnership development exercises. The book moves on to hand evaluation and follows with a complete range of opening bids from 1C to 4S in all seat positions. Finally, it deals with responses to an opening bid. This convention-rich system can be simplified to suit the requirements of individual partnerships at any level. Developing partnerships can start with the basic system and then add to it with the understanding that everything will work seamlessly together. The system's bidding philosophy is to aggressively locate and bid game contracts. Bidding structures derived from that approach depend upon shape and high-card points to differentiate between types of bids. Patterned after a college textbook, 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.
