The origin of this method is unknown although is has been strongly suggested that the concept originated in Taiwan in the 1950s. Any additional information as to the identity of the author, also photographic material, would be greatly appreciated.
According to Mr. Chris Ryall online these Weak Two Bids are considered in the class of Brown Sticker conventional methods. Such conventional methods are banned by certain national and international sponsoring organizations, sometimes only in the level of competition, and are generally restricted by the sponsoring organization.
According to members of the online bridge forum rec.games.bridge it seems that the recollection is that a certain Mr. Chih Kuang (sometimes hyphenated) of Taiwan proposed during the 1950s the following three openings on the two level in order to communicate certain information with double meanings.
Speculation is that following the conclusion of the World War II and the creation of Taiwan by Chiang Kai-shek in the mid to late 1940s the Tiawanese, who followed, had learned of the game of bridge from the several so-called liberators. As the publication of various bridge books by more experienced bridge authors had not been offered in the newly formed area many exotic conventional methods evolved. Most of these conventional methods have been forgotten, become obsolete, and/or were never recorded. The Chih-Kuang Two Bids, however, is one of the remaining conventional methods, which survivied.
Principle of the Concept
The concept is that all bids on the two level, except an opening of 2 Clubs, are considered to be bids that are either weak Major Two Bids or weak distributional 5-5 types.
The point range is generally the standard range of Weak Two openings between 5 and 11 high card points, but may be based also upon the number of Losing Tricks. Responses are per 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 n ot 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.
