The most complete guide to the modern methods of standard bidding for bridge, from one of America's leading players, teachers, and authorities. With a logical, easy-to-follow style, William Root covers all the bidding essentials.
Though old (for a bridge book) and thus not covering some modern bidding conventions (e.g. Jacoby), this is an excellent book for intermediate bridge players. It is very well explained, well written, and with good examples throughout.
