Competition brings many benefits or so all the politicians say. Bridge players certainly subscribe to the theory. These days somewhere between two thirds and three quarters of all auctions see both sides entering the fray.

You will often hear rules quoted such as "do not double them into the game" or "leave the five level to the enemy". This book covers all the rules likely to help you and, as usual in this series, you will find plenty of examples both for and against each one.
