The origin of this concept is unknown. Owing to its lack of an anchor suit this conventional method is classified as a Brown Sticker convention and is only permitted in special bridge tournaments and final rounds of tournaments conducted by the World Bridge Federation. Before employment the player and partnership must submit for authorization by the sponsoring organization.

Principle of the Concept

The concept is the same as a normal Weak Two opening bid with multiple meanings and clarified by the opener with the rebid. The high card point values are fewer than an opening count and the Weak Two bid is dependent on distribution. The opening bid of 2 Spades shows either of the following features.

1. Shows 8-12 high card points, or
2. promises a distribution of 5-5 in both Minor suits, or
3. promises a distribution of 5-5 in both Major suits, or
4. promises an unidentified semi-solid Major suit.


The bid by the responder of 2 No Trump is generally considered mandatory. The responder may hold zero values, but in the instance that the immediate opponent passes, then the responder is forced to relay. This first response allows the opener to clarify his holding. Upon clarification of the opener's holding the responder decides how to establish the final contract.

By immediate interference the partnership should have an understanding as to whether to play systems on or systems off. Any and all continuations are a matter of partnership agreement following any immediate competition.

Clarification by the Opener

3 : Promises a distribution of at least 5-5 in both Minor suits, Clubs and Diamonds.
3 : Promises a distribution of at least 5-5 in both Major suits, Hearts and Spades.
3 : Promises a semi-solid Heart suit. (Note: suggested length is a 6-card suit.)
3 : Promises a semi-solid Spade suit. (Note: suggested length is a 6-card suit.)



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.
