Conventions are a vital element of bidding in bridge. Unless they are easily and clearly understood they can be destructively dangerous. This book contains the most common conventions you are likely to encounter at the duplicate table, together with defensive measures you can take, plus countermeasures against each part of the defensive methods.
Importantly, however, bridge continues to evolve. The material in the additional chapter covers the most recent developments in bridge bidding and will give you ideas for inclusion in your regular partnerships.
