Conventions are a vital element of bidding in bridge and, unless they are clearly and easily understood, they can be destructively dangerous. Bridge Conventions, Defences and Countermeasures explains each convention and covers in detail how it can be used and how it is often misused. Ron Klinger, one of the world's top bridge teachers and authors is a brilliant exponent of the subject and has here produced the leading book of conventions - no keen player should be without it.
