Ever since the game of bridge has become popular, competitive, and a means of leisure, bridge players from around the world have been trying to define 52 cards. They have devised many conventions, treatments, methods, formulas, techniques and approaches to describe 13 concealed cards to their partner who is also holding 13 concealed cards. With all of these arrangements, bridge players have been hoping to also convey a certain mathematical strength and card length.

As soon as these arrangements have been devised, developed, refined and altered, these bridge players have given names to these methods, which have ultimately become designated as systems. From these different systems, the bridge player may choose the conventions and treatments he will wish to include in his or her repertoire or agreement. From these devised systems come very many conventions and treatments which the individual bridge player still uses and employs today.

Following is an incomplete list of Bridge Bidding Systems, but it contains those systems which have survived the challenge of time and popularity. In listing these bidding systems, developed and devised by so many of the pioneering bridge players and those, who followed, the attempt is made to recognize their efforts, record their work, and provide them deserved credit.

The attempt is made to include as many as possible. If a bidding system is missing, then any contributions, suggestions, and/or recommendations shall be greatly appreciated. The attempt has been made to also include those bidding systems, which did not stand the test of time and have been forgotten or are simply collecting dust on the shelf.

The bridge student should be aware that some of these bidding systems have been lost to time, are no longer in published publications, are to be found in books not available to Bridgeguys.com, and the bidding system can only be outlined and not completely presented in its original form. The bridge student must also remember that a bidding system is a living entity and evolves, meaning that the entirety will change with time. The attempt is made to present the bidding system as originally designed.

Note: It is worthy to note that the development of bidding systems for the game of bridge were multitudinous and many early bridge students, players, and perhaps self-proclaimed bridge experts wished to somehow have their name attached to an approach, a treatment, a bidding system. Therefore, it was considered traditional in the pioneering days to attach the designation of bidding system to any new approach. This designation has been more narrowly defined over the years and what was once considered by the bridge community to be a bidding system can no longer be defined as such. However, since the work of these pioneers should be remembered, the designation of bidding system will be employed as published in the early works, books, pamphlets, etc., without change. We ask for the understanding of our visitors.

Aces Scientific Bidding System
Mr. Ira Corn of Dallas, Texas, had a goal and that was to reclaim the World Team Championship Title to the United States. With his financial aid, he formed a group of professional bridge experts, purchased a set of computers, and developed the Aces Scientific System. Mr. Robert Goldman acted as perhaps the chief designer.

Acol Bidding System
Acol is a bidding style or bidding system, which was developed in the early stages of the evolution of the game mainly in the United Kingdom. The Acol bidding system is not specifically a system etched in stone. This means that the Acol bidding system is rather interpretable and allows a stronger latitude in flexibility according to the partnership agreement. Since this bidding system is flexible the presentation is not of a designed bidding system, but rather the features of the system listed separately on an individual web page.

amBIGuous Diamond System
The origin of The amBIGuous Diamond bidding system is unknown. We are very thankful to Mr. Marvin French of San Diego, California, for contributing this information. The amBIGuous Diamond system is designed for matchpoint bidding. It combines the advantages of real-suit bidding with the bidding of notrump with all notrump-type hands (and only notrump-type hands). The bidding system permits and features four-card major opening bids. This information has only been archived and preserved on this site in .pdf file format for future reference.

Ambra - 2000
The origin of this designation is unknown. This .pdf file is in Italian. This is a compilation, with added variations, of the methods based on the Two Over One bidding system devised by Mr. Benito Garozzo for the Italian 2000 World Junior Championships.

Ambra Version 2.6 2004
This .pdf file is in English. In Ambra, Version 2004, Mr. Benito Garozzo has solved the dilema on what to open with 16 high card pointsand a 5-card Major suit in a balanced hand. Many partnerships open 1 No Trump nowadays with 5M-3-3-2 distribution, but in Ambra Version 2.6 we open 1 Spade and 1 Heart and we can control the bidding with the many relays available. Contributions to Ambra Version 2.6 have been made by Mr. Benito Garozzo, Mr. Davide Tavoschi, Mr. Ronald (Ron) Denny Klinger, Mr. Daniel Neill, Sharon Guy, and Gijs van Haarlem.

Amsterdam Club Bidding System
This approach was developed in earlier stages of the game of bridge, as many other bridge bidding systems or approaches, and additional information is not available. The Amsterdam Club System has undergone many changes, multiple variations have been added, and the system has been modified. Only the opening bids are presented.

Approach Forcing System
This designation may be applied to most standard methods of bidding. The perhaps earliest developed system in the game of Duplicate Contract Bridge was developed by Mr. Ely Culbertson, who advocated the principle of slow arrival in order to communicate as much information about the holdings as possible. The Culbertson System was followed by many other bidding systems, which employed the same foundations, guidelines, approaches, and structures, such as a new suit being forcing and a preference of establishing a suit contract as opposed to a No Trump contract if a fit was found.

Note: The Approach Forcing System devised and developed by Mr. Ely Culbertson is a culmination of his many publications printed and promoted in the early stages and ages of the game. These publications, however, required many revisions in the following years owing to the development of many new conventional methods at that time. Therefore, for this reason the Approach Forcing System of Mr. Ely Culbertson cannot be reduced to a concrete formula and certain bids, much less the continuances thereof.

Note: Of interest is the Approach Principle devised and promoted by Mr. Ely Culbertson. Information is provided in a .pdf file format with copies of the original published book titled Contract Bridge Complete.

Assiste Bidding System - Il sistema Assist - (Assist Bidding System)

This is accomplished by expanding and enhancing the standard balanced openings.

Bangkok Club Bidding System
When one of the bridge players at the bridge table opens 1 Club, then that bridge player could be using the Bangkok Club System devised by Mr. Somboon Nandhabiwat. This Club System was used with some success in several world championship tournaments.

Baron System of Contract Bridge
This is a bidding system devised and developed over years, beginning in the early 1940s, by Mr. Leo Baron, for whom the system was named, Mr. Adam Meredith, and other co-developers. Although described as an English bidding system in many publications, the bidding system is rather for those players of the United Kingdom, whose basic approach to the game of bridge is Acol. Many features of the bidding system, such as bidding up the line, or an immediate raise of partner's suit always requires at least 4-card support, have become firmly established in the fundamental theory of the game.

Note: Mr. Leo Baron died in the year 1985 and was of Harare, Zimbabwe, although born in England. After retiring from the active play he emigrated to the country of Rhodesia, now Zimbabwe in the year 1952. Among his other achievements he became Chief Justice of Zimbabwe and also later Zambia.

Note: Mr. Adam Meredith, born in the year 1913 and died in the year 1976, who was born in County Down, Ireland, but resided in New York City, New York, United States, co-authored the publication Baron System of Contract Bridge together with Mr. Leo Baron.

This book was adapted from the French by Mr. Terence Reese and the Introduction was written by Mr. Omar Sharif. The book was published in 1969. A simplified version is presented.

Bocchi-Duboin Bidding System
This is a short summary of the bidding system employed by two international bridge personalities. Mr. Norberto Bocchi, born September 29, 1961 in Parma, Italy, is a bridge player on the international level. Mr. Norberto Bocchi has won five World teams championships along with six consecutive European teams championships and a seventh European in 2010.

Note: Summary of the Bocchi-Duboin Bidding System can be found online at this source. This article has also only been archived and preserved on this site in .pdf file format for future reference.

Note: In an interview by Laura Camponeschi for the Neopolitan Club with Mr. Norberto Bocchi, he speaks about The Big Bang Theory. This article was posted on October 8, 2013 and presented is only one small quote from Mr. Norberto Bocchi: We work hard on the system, our partnership is based on an accurate and comples system, called "Big Bang", which we developed.

Bocchi-Duboin Opening Bids
These opening bids are the principle features of the bidding system developed by Mr. Norberto Bocchi and Mr. Giorgio Duboin, both of Italy.

Bolish Club
A system that has evolved from EHAA+ (the version of Mr. Jari Böling of EHAA, Every Hand An Adventure), and is now more similar to Polish Club. Other sources of inspiration are Keri by Ron Klinger, Ambra by Benito Garozzo, and Einari Club (a local Blue-team-like system, something of a standard in Turku). This information has only been preserved and archived on this site in .pdf file format for future reference.

CAB Bidding System
CAB is an acronym for Two Clubs, Ace-asking, Blackwood, and although the system is no longer used, the system did have some popularity in England during the decade of the 1950s. The development of the CAB bidding system is accredited to Col. George Gordon Joseph Walshe, who was born in the year 1873 and died in the year 1959, and who lived in London, England.

Chester Club Bidding System
The Nottingham Club bidding system, developed at the Nottingham Bridge Club, was first published by Marjorie Burns in 1954. To make the system more playable, it has been modified over the years by various Deva club players notably Eric Figgis, David and Barbara Figgis, Dorothy Grunert, Wilf Fearn, Eric and Dorothy Dutton,Frank Dean, and more recently by Jim Stambridge and myself, Charles Ro. Greenwood. Over the years the revisions clouded the original Nottingham conventional method and became renamed the Chester Club Bidding System. This information has also only been archived and preserved on this site in .pdf file format for future reference.

Crane Bidding System
Mr. Joshua Crane devised, developed, and promoted this bidding system, which was a system created in the early stages of the evolution of the game of bridge. He was an all-round talent in the sports world. He was proficient as a racquet ball player, riding horses / ponies playing the game of polo, sufficiently talented on the tennis court, a tried and true yachtsman, and also an expert player at the new game of duplicate bridge, which had evolved from auction bridge.

Demicoma System
This is the designation of a bidding system as originated by Mr. Prakash K. Paranjape of India, and presented in his publication Easier Done Than Said: Brillancy at the Bridge Table, January 1998, published by Master Point Press, Toronto, Canada, ISBN-10: 1894154002 / ISBN-13: 978-1894154000. The link is to his website. As explained on the site by the author: The development of DEMICOMA began as PEAS (Dr. Deepak Khemani coined this term. PEAS stands for Paranjape Early Asking System), an aggressive slam bidding methodology, in mid-1981. A sort of backward integration led to DEMICOMA in its early form and about 80-page notes were prepared and cyclostyled for the benefit of IIT boys in 1986. There was no further printed publication after that.

Note to the Reader: the word cyclostyle refers, as a noun, in the industries of printing, lethography, and bookbinding to a kind of pen with a small toothed wheel, used for cutting minute holes in a specially prepared stencil. Copies of the design so formed can be printed on a duplicator by forcing ink through the holes.

Note to the Reader: the word cyclostyle refers, as a verb, to an instrument for cutting stencils from which multiple copies of an original can be made. From 1998-2001, he was the honarary joint secretary of the Bombay Contract Bridge Association.

Note: From 1985-1987, Mr. Prakash K. Paranjape was the honarary joint secretary of the Thane District Bridge Association, of which, he was also a founder member. From 1998-2001, Mr. Prakash K. Paranjape was the honarary joint secretary of the Bombay Contract Bridge Association.

Dutch Spade
As the record has it this system was invented by Mr. Max Rebattu in the year 1982 while vacationing on the beach. However, this approach is, more accurately, designated as a conventional opening method rather than a complete bidding system. The concept revolves around the idea of employing transfer bids by bidding one rank lower in order to accomplish the transfer. The method also uses the concept of a forcing pass system, and may be therefore described both as an opening bidding system and a conventional method, but not as an established bidding system. See also the Forcing Pass Systems compilation of Mr. Jan Eric Larsson and Mr. Ben Cowling of June 19, 2001, which is presented in .pdf file format and will automatically opened by your browser.

ERS
A natural bidding system devised and developed by Mr. Evgeny Stolitsa, who was born in the Russia Empire in the year 1905, the year in which the infamous Russian Revolution of 1905 began. In later years he emigrated to the country of Bulgaria, and mainly resided in the capital city of Sofia. He introduced the game of duplicate bridge to the citizens of Bulgaria, and also organized the players into a community, from which today the Bulgarian Bridge Federation evolved (Булгариан Бридге федерация). He occupied the role of the leading bridge theorist until his death in the year 1985. OEofB6th745.

Note: The meaning of the designation of ERS is unknown and any additional information as to this bidding method and also the bridge personality of Mr. Evgeny Stolitsa would be greatly appreciated, especially photographic material.

Note: Mr. Evgeny Stolitsa is also the developer of the bidding system called Ultra Texas. No additional information as to the structure of either ERS or Ultra Texas is known, and it is not known whether a publication exists with these two bidding systems as content.

Finnish Expert Bidding
This is a write-up on Finnish Expert Methods by Mr. Pekka Viitasalo of Espoo, Finland (website). The initial concept began in June 2006 and has evolved over the years to the present version. In the words of the author: This document is addressed for experienced bridge players. No basic bidding sequences or calls are described. From the version 3.0 onwards I have introduced some more bidding philosophy describing some basic bidding sequences to help people with less than expert status to understand why certain sequences have pretty clear meaning even though they are not discussed in details. The main reason for this addition is the fact that FEM was taken as the official system for the Finnish MSC equivalent. Note: This information has also only been preserved and archived on this site in .pdf file format for future reference.

According to the authors Magic Diamond sprung from Carrotti when the administrators decided to make life hard for players, who adopted these tactics, the main idea being to get rid of the hateful pass opening. The authors of the version called Magic Diamond Light are: Mr. Sven-OlovFlodqvis and Mr. Tomas Brenning. The principles behind the system are, among other features: 1. Natural approach with bilateral exchange of information rather than relay bidding, and 2. Well and narrowly defined strengths for most openings to enable fast arrival as often as possible.

Note: Following the development of the Magic Diamond system it became apparent that the devised system did not fall within the parameters as established by the bridge sponsoring organizations such as the WBF, ACB, SBF, EBL. Magic Diamond Light is as stated by the authors a clean, basic version of Magic Diamond with focus on natural bidding and few but frequent conventions.

Note: The authors have removed the link to their website and therefore only the preserved and archived version of Magic Diamond Light, Version 1.0.1., dated May 29, 2001, in .pdf file format is presented on this site for future reference.

Marmic
An Italian system, the name of which is derived from the first letters of the first names of its inventors Mr. Mario Franco and Mr. Michelle Giovine, hence Mar-Mic. This system is no longer played today.

MG Precision Handbook
This is a Precision bidding system handbook for those serious about playing a more sophisticated and scientific system, devised by Mr. Greg Earnest and wife/bridge partner Meaghin Burke of Oxford, Mississippi, United States. Mr. Greg Earnest has published this information privately and offers it for purchase on his web blog. This information has also been archived and preserved on this site in .pdf file format for future reference. The serious bridge student should, by all means, research the information as published by Mr. Greg Earnest.

MG Precision Cuebids
The development of this bidding method is credited to Mr. Greg Earnest together with wife and partner Meaghin Burke. The first letter of their first names constitute the initials of this bidding approach. The concept and employment of these particular cuebids lie in the fact that they are able to show game values, 4-card plus support, slam interest, and promise also a first-round control in the suit bid.

MG Opening Bids Only
The opening bids of the MG Precision bidding system are listed separately.

Monaco Bidding System
The Monaco system was the original Relay System. It was devised by Mr. Pierre Ghestem of France around 1954, and used with Mr. Rene Bacherich in several World Championship tournaments. The main concept of the relay system is to bid in such a manner as to make the stronger hand become the declarer in the final contract.
Although not officially a bidding system, this concept was a prototype of the evolving relay systems being developed, and which later found adherents within the bridge community.

MSklövern
Systemet presenterades i Bridgetidningen 1981 av Max Ödlund. Modern Standardklöver eller lättare sagt MSklövern är Modern Standard med stark 1-öppning. I princip kan man säga att buden 1och 2har bytt plats. 1visar minst 17 hp och uppåt. De andra färgöppningarna på enläget begränsas således till 12-16 hp. Annars är det i stort sett som Modern Standard. 2visar minst 5-kortsklöver och 12-16 hp. 1NT visar som vanligt 15-17 hp. 2NT 20-21 hp. Ett enkelt system för dig som spelar Modern Standard och vill pröva stark klöveröppning. Systemet kan utvecklas och byggas på efter eget huvud.

Note: Apologies if several characters do not appear correctly.

Rough Translation: The system was first published in the Bridge Magazine (Bridgetidningen) in 1981 by Max Ödlund. Modern Standard Clubs, or easier said, MSklövern, is Modern Standard, with a strong 1 Club opening. In principle, one can say that the bids of 1 Club and 2 Clubs changed places. 1 Club promises at least 17 high card points plus. The other suit opening bids become therefore limited to 12-16 high card points. Otherwise it is almost as Modern Standard. 2 Clubs promises at least 5-cards in Clubs and 12-16 high card points. 1 No Trump shows the usual 15-17 high cardpoints. 2 No Trump promises 20-21 high card points. This is an easy system for the bridge player to play Modern Standard and who wishes to try strong Club opening bids. The system can be developed further with this foundation. Source.

Orient Bidding System
This particular bidding system was developed, invented and authored by Mr. Syed Asghar Hassan of Pakistan in the year 1998. It represents a new approach to precise and targeted bidding and is based on a dynamic hand evaluation method. The picture of Mr. Syed Asghar Hassan is presented below, and which can be found only on the online presentation of his bidding system.

 

 

As stated by the author online in the year 2003: The Orient Bidding System also has the unique distinction of overcoming nearly five-decade old shortcomings associated with the most widely used Point Count method which works satisfactorily on balanced but not on distributional hand. With the Orient Hand Evaluation method, both the balanced as well the distributional hands can be evaluated on a uniform basis using the same yardstick. This is not possible with the Point Count method advocated by Goren in the late forties.

Note: It seems that the author, Mr. Syed Asghar Hassan, only published his bidding system online.

The following are links to .pdf files, which will be automatically opened by your computer in a new window. These .pdf files have been yaken off line following the death of Mr. Syed Asghar Hassan in the year 2011. These.pdf files have only been preserved and archived on this site for future reference.

Rothshild Contract Bridge Bidding System
This is a designation for a bidding system contained and explained in the publication titled The Rothschild Contract Bridge Bidding System, publisded in the year 1931. Library of Congress code is LC: ca 31000449. The originator and developer is assumed to be Mr. Joseph M. Rothschild. Any additional information will be greatly appreciated.

Roth-Stone Acol With Pakistani Preempts

Stone Age Acol with Pakistani Preempts
This is a designation for the bidding system devised and developed by Mr. Munir Ata-Ullah of Pakistan. Al opening bids from 2 Diamonds through to and including the bid of 4 Diamonds are artificial and have multiple meanings. Several bids within this range of these two bids have as many as seven possible meanings, which are clarified in the subsequent bidding sequences and identify the hand type, the suit quality, and the values.

Note: For the partnership it proves difficult to determine the best contract quickly with the fewest number of bids and rebids since the nature of the holding must first be clarified and determined.

Note: Any defense method by the opposing players is made difficult since the nature of the bid is artificial and the meaning of the bid must again first be determined.

Note: Source is OEofB, Newly Revised, Fourth Edition, 1984, page: 414. Information about this method is rather limited and any assistance, any information, any additional literature would be greatly appreciated.

Note: This version of Stone Age Acol is not to be confused with the designation stone-age Acol, which is a general reference to the originally developed concept (and only slight variations thereof) of the Acol bidding system as devised in the early 1930s in the bridge club on Acol Road in London, England, which is still played in many parts of the country.

Strong Pass Relay Ever Avoiding Defending - SPREAD
Authored by Mr. Mark Abraham and published online in its latest updated version in the year 2005. This system is a major advance within the SCRAPE framework (Strong Club Relay Avoiding Passing Ever). It features a strong pass with variable-captaincy relays for positive responses that ensure an unbalanced hand shows shape opposite a balanced hand whenever this occurs. The 1 Club and 1 Diamond openings are double-under transfers with immediate differentiation of game-forcing relay, invitational probe and non-forcing auctions. This information has been preserved and archived in .pdf file format on this site for future reference.

Super Precision

Mark Donovan - Super Spade
This bidding system is devised by Mr. Mark Donovan. This is Version 2 and published online in July 2007. Online source. The system has been designed to take into consideration the fact that the most popular contract in duplicate bridge is usually Spades. Whoever has Spades ends up winning the auction. Playing in Spades also usually scores better then playing in a Minor suit. The first radical step of the system is that an opening bid of 1 Club shows 4 plus Spades. This information has been preserved and archived in .pdf file format on this site for future reference.

Note: Super Spade, Version 3, authored by Mr. Mark Donovan in March 2010 can be obtained at his online website. This information has also only been preserved and archived on this site in .pdf file format for future reference.

Symmetric Relay Contract Bridge Bidding System
This is a summary of the Symmetric Relay Bidding System as compiled and authored by Mr. Adrei Sharko. The attempt by Mr. Adrei Sharko is to update and to release a revised edition of the contents of the publication titled Symmetric Relay, authored by Mr. Walter Jones and Mr. Roy Kerr, and published in the year 1980. The link is to the .pdf file of Mr. Adrei Sharko as maintained by the Australian Bridge Federation.

Tangerine Club Bidding System
This bidding system was developed in 1995 by Mr. Jan Eric Larsson. Tangerine Cub was born out of distrust for the standard system, and incorporates features from other bidding systems, such as the Neapolitan Club, the Blue Team Club, Precision, and the Swedish system Hjortron, (Cloudberry). Tangerine Club was invented at the same time as Cloudberry, and precedes the weak/strong Carrot Club with more than five years.

T-Precision Bidding System
Developed by Mr. Steve McGrahan of Hamilton, Ontario, Canada, these opening bids represent his latest version 1.87 dated May 15, 2011, in pdf file format. These opening bids and the continuances have been developed over time and there have been improvements amended to the entire system, thereby creating a newer version. This information has been conpiled in .pdf file format by Mr. Steven McGrahan and has only been preserved and archived on this site in .pdf file format for future reference.

Transfer Oriented Symmetric Relay Precision
This bidding system, based on the original concept of Mr. Charles Chung Wei, is a work in progress. The basic element of the bidding system is that a 1 Club opening bid shows a minimum of 17 plus points if balanced, and 16 plus points if unbalanced. The first recorded version is of August 1999 and proceeds in its evolution through several updated versions, which may be only months apart. A web page containing most of the versions is maintained on the Internet by Mr. Joon Pahk, who has become, as self-described the keeper of the notes, which he describes also as a living, breathing monstrosity of a document.

Source: The actual website of bantha.org no longer exists. However, Mr. Joon Pakh maintains these web pages, which list the versions of the Tranfer Oriented Symmetric Relay Precision bidding system.

Note: As far as can be determined there were several originators of this bidding system and the attempt has been made to include all names, which are: Mr. Kevin Bathurst, Mr. Josh Donn, Mr. Ari Greenberg, Mr. Samuel Ieong, Mr. Joon Pahk.

Note: The following list contains most of the versions from the original in chronological order. The bidding system was provided with the designation of TOSC almost from the beginning.

Trench War Club
Mr. Henk Uijterwaal of Rozendaal, The Netherlands, originated the Trench War Club, which is a bidding system that combines both weak and strong holdings. In the words of the author the name of this bidding system is derived from a chapter in a 1980s book by Robert Sundby on his Breakthrough Club system. The reader should observe any copyright. This material has also only been preserved and archived in .pdf file format on this site for future reference.

Tübingen Pass
This is a Forcing Pass Bidding System. The origin is unknown. The source is the website of Mr. Gerben Dirksen of Tübingen, Germany. This system is based on Weak Opening System methods and Prepared Club. It employs a two-way pass that is either weak or strong. Opening bids at the one-level require 17-24 Opening Points (HCP + 2 longest suits), 3 points less as the minimum opening bid in most systems. This information has also only been preserved and archived on this site in .pdf file format for future reference.

Two Over One

Ultimate Club

Ultra Club Relay System
Developed and devised by Mr. John Lowenthal, born in the year 1938 and died in the year 2000, who is also the the co-developer of the Canary Club System together with Mr. Paul L. Heitner, born in the year 1910 and died in the year 1996.

Universal Club Bidding System
This bidding system was developed by Mr. Fred R. Thomas and was published in the year 1980 by the UNICLUB Press, located in Los Angeles, California, United States. The title of his publication is Universal: The System For Everyone, and in the words of the author, is so named because it is the one system that is natural and also universally suitable for everyone, average players as well as the experts.

Universal Club Two Clubs Opening
In the Universal Club bidding system, developed by Mr. Fred R. Thomas, the opening bid of 2 Clubs has been assigned a specific meaning, which is that it shows a three-suited holding, generally a distribution of 4-4-1-4, with values between 12 and 17 high card points. A minimum and a maximum point count is known and also the short suit, which is Diamonds.

Universal Club Two Diamonds Opening
In the Universal Club bidding system, developed by Mr. Fred R. Thomas, the opening of 2 Diamonds has been assigned a specific meaning. This opening bid promises a three-suited holding. The required point count is between 16 and 21 high card points. This opening demands that the Diamond suit be one of the three suits as opposed to the 2 Clubs opening bid, which shows Diamond shortage.

Universal Club 2 Hearts and 2 Spades Opening
The Universal Club bidding system, developed by Mr. Fred R. Thomas, has relegated special, if not specific, information in the opening bid of either 2 Hearts or 2 Spades. Either of these two openings promise at least a 5-card card, or longer, and a second, unspecified second suit, also a 5-card suit, or longer. The point range is a minimum of 14 high card points and the upper range is unlimited. Therefore, these two opening bids are forcing for one round. They are not considered to be absolutely game-forcing in nature.

Weak Opening Systems
Weak Opening Systems, or WOS, have become bidding systems in their own right. The first such system was primarily accomplished by Mr. Jukasz Slawinski of Poland. It was based originally upon the concept behind a Strong Two Club bidding system. This concept was revised, expanded, and amended. The most distinguished difference is that a player must pass with a good hand, called a Forcing Pass, but is forced to open the auction with zero values, such as a Yarborough.

We Bad
This is a scientific 5-Card Major System played by Mr. Don Weiner and Mr. Dave Babcock. The bidding system is a a scientific 5-Card Major system very distantly descended from Bridge World Standard. As expressly stated: where the present document is silent or unclear, the Bridge World Standard document is operative. Mr. Don Weiner and Mr. Dave Babcock provide a list of the publications, which are especially pertinent to the We Bad system. They also provide in the document the Complete System of the Bridge World Standard as of the year 2001. This online document is only preserved and archived on this site in .pdf file format for future reference.
