The origin of this variation of the Stayman convention is unknown. The concept is based on the idea of showing the strength of the opener on the second round of the auction. Once the asking bid of 2 Clubs, or Stayman, has been bid by the responder, then the opener will communicate the possession or non-possession of a 4-card Major suit plus minimum or maximum values of the No Trump opening with the following rebids:

Once the responder is aware of the strength of the No Trump opening plus the inferred distribution, then the responder can continue the auction accordingly. If the opener shows both 4-card Major suits, with a 2 or with 3 rebid, then the responder can make a transfer. If the responder rebids 2, then this is a transfer to Spades. If the responder rebids 2, then this is a transfer to Hearts. In this manner the stronger partner still becomes the declarer and the lead comes up to him. However, it is the responsibility of the responder to place the final contract, whether partscore, game, or slam.
If you wish to include this feature, 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.
