Rules - More Rules - Mathematical Rules

There are certain mathematical calculations which enter into the bidding, the play and the defense procedure. These calculations are important in their application and should be used under the correct circumstances. They help in assisting and deciding which card to play, which defense and which offense strategy to use, and they keep the Line of Communication open, especially between the opponents. They should be used with accuracy due to their effectiveness. They can make the difference between a made contract or a set contract.

There are several Rules, and each one has its place at the bridge table. The attempt has been made to list those rules, which are perhaps universal. Also, the attempt has been made to list those rules, which are the result of practical experience and have been proven to be effective. The latter have been described in so-called one-liners, and we hope that the reader devotes his or her attention also to these general guidelines.

If you wish to include these rules, or any other feature, of the game of bridge in your partnership agreement, then please make certain that the concept is understood by both partners. Be aware whether or not the feature is alertable or not and whether an announcement should or must be made. Check with the governing body and/or the bridge district and/or the bridge unit prior to the game to establish the guidelines applied. Please include the particular feature on your convention card in order that your opponents are also aware of this feature during the bidding process, since this information must be made known to them according to the Laws of Duplicate Contract Bridge. We do not always include the procedure regarding Alerts and/or Announcements, since these regulations are changed and revised during time by the governing body. It is our intention only to present the information as concisely and as accurately as possible.
