The origin of the Splash convention is unknown, but is rumored to have roots in bidding systems employed in Australia. The designation is an acronym of the phrase Suit Plus A Suit Higher.
The idea behind the concept is identical to the DONT conventional method against an opening of No Trump on the one level by the opposing side as devised by Mr. Marty Bergen, an American bridge personality and author, except for one single principle.
Note: The only different principle between the concept of DONT and Splash is that a double employed by DONT conveys the information that the overcaller holds a one-suited holding sufficient to compete against the range of the No Trump of the opener. This meaning is different in the Splash conventional defense method, in which the double is only employed as a penalty double against the No Trump opening bid by the opposing side.
Note: All other continuations are identical with the DONT conventional defense method.
Note: Whether or not the Splash conventional defense method can be employed in the fourth seat following two consecutive passes is a decision of individual partnership agreement.
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.
