Mrs. Hayden was the first and youngest member of the American International Bridge Team and is one of the leading exponents of the game. Her book, which is for beginners, represents her use of ""natural bridge"" with minimal conventions (held to one chapter). And while discussing all kinds of bids, rebids and responses, she also goes into some of the finer points of play-- leads, discards, probabilities of distribution. Most of the book consists of basics (rules) followed by a good many self-testing quizzes. The market will be there.
