This conundrum was written by Barbara Seagram together with David Bird and was originally published in the book, Bidding at Bridge - A Quizbook - you can find out all about it further down the page.
This book gives the near-beginner a chance to practice the principles on which sound bidding is based, from the opening bid onward. This is not just a series of problems, however. Each section contains a brief introduction to its topic, and the ideas are reinforced with carefully explained solutions and helpful tips throughout. Bridge teachers and students will find this book invaluable.
