Each book in this series allows players to learn a new convention, then practice using it either on their own or with a favorite partner.

All North American players are taught to play using a strong notrump, but that is not the way of the rest of the world. Even in North America, weak notrump systems, or even Kamikaze notrump systems, are becoming more common. This book discusses the advantages and disadvantages of playing a system with a weaker notrump opening, and shows how the 1NT range impacts the rest of the bidding system. Even those who have no interest in converting to a weak notrump range still need to know how to play against weak notrump systems, so for them the book includes advice on effective competitive methods.
