A follow-up book from the author team that produced the award-winning and best-selling 25 Bridge Conventions You Should Know. Aimed at the same novice/social player audience as their first book, this new title deals with competitive auctions in which the opponents have opened the bidding. This is the most complex area of bridge bidding, and has never up to now been dealt with comprehensively in a book that is understandable for non-experts.
