Bridge: The Expert Improver by D.L.M. Roth
This sequel to Bridge: The Expert Beginner emphasizes the transition from playing while being allowed to see all four hands to playing in real life, with only one hand on view during the bidding and two during play. The idea of the book is to reconstruct the unseen hands and play as though you can see all four. Although this takes time and practice, it will repay its investment many times over. In this book, the expert improver learns more about the partnership understanding in both bidding and defence as well as new techniques in declarer play. Examples are given of common hands which will require similar types of play.
