Object Of The Game
In duplicate bridge, the object of the game is to score points on a particular deal or board. One other opinion among bridge experts is that the object of bidding in contract bridge should be to bid in such a manner as to get the opponents into a contract which the can not make, double and then set them.
Obligation To Pass
When a player bids out of rotation, the Laws require as a penalty that his partner must pass when next it is his turn to call, or for the duration of the auction. If, however, that player under such an obligation to pass makes a bid, double, or redouble, then both members of the offending partnership must pass for the rest of the entire auction. See Laws 27 to Laws 40.
This is a term which defines a play which can not lose, but may win a trick when the situation is such that not to make the play will gain nothing and will lose the opportunity of making a trick that might otherwise be sacrificed, as an obligatory duck or an obligatory finesse.
This is the play of a small card on the second lead of a suit in the hope that the adversary yet to play holds only the commanding card of the suit. The object of the obligatory finesse is to limit the number of losers in the suit when only two of the five honors are held.
Obvious Shift Principle
A carding method from A Switch in Time by Pamela and Matthew Granovetter. At Trick 1, partner of opening leader compares the led suit and obvious shift suit. Encouragement, upside-down or standard, denies tolerance for the obvious shift suit. Discouragement actively confirms tolerance for the obvious shift suit. This applies whether opening leader will maintain the lead or not.
This is the designation given to the later, revised version of the bidding system called Carrot Club.
O'Carrot Club Opening Bids
The O'Carrot Club opening bids represent the newer version of the Carrot Club opening bids. This version was developed by Mr. Sven-Olof Flodqvist, who played it with Mr. Svante Ryman, Mr. Hans Gothe, and Mr. Lars Andersson in order to satisfy certain sponsoring bridge organizations, which declined to accept the original version (Carrotski Club) under their Rules and Regulations policies.
Occam's, or Ockham's razor is a principle attributed to the 14th century logician and Franciscan friar, William of Occam. Ockham was the village in the English county of Surrey where he was born. The principle states that Entities should not be multiplied unnecessarily. Sometimes it is quoted in one of its original Latin forms to give it an air of authenticity.

1. of a level, as "one-odd" at the one-level.
2. of tricks, six more than the number specified, as "two odd tricks" or eight tricks altogether.
A defensive signaling method in which odd-numbered cards, such as the three, the five, are encouraging, and the even-numbered ones are discouraging and may have suit-preference implications. The one disadvantage to this method of discarding is the fact that the player will always encounter holdings where no odd and/or even discard is possible. Therefore, some partnerships treat some even discards as more discouraging than other discards. A discard of a three, for example, can be a more encouraging signal than a discard of a 9, when no even card is available. The partner should deduce from his holding and that of the dummy whether or not the partner may hold no even and/or odd cards to discard correctly. Note: This practice may be allowed in ACBL play only on the first discard. Please check.
According to the ACBL General Convention Chart, a partnership may use odd/even or other forms of dual message signaling on each player’s first discard only. Otherwise, signals must be either right side up or upside down. A player who deliberately violates this rule subjects his partnership to adjusted scores when the opponents are damaged through the use of an illegal agreement, procedural penalties even when there is no damage, and possibly more severe penalties. Mike Flader - ACBL Rulings
A trick won by the declarer in excess of the first six tricks. The phrase is from the game of Whist in which the winning of the odd trick was paramount.
This is a rule devised by Mr. Alex Traub of South Africa to help the declarer who must make a series of plays, and/or ruffs, and needs to end up in a specific hand. If this specific hand is considered to be the master hand, then the first trick must be won in the master hand if an odd number of plays must be made. Conversely, if an even number of plays must be made, then the first trick must be won in the non-master hand, or the "satellite hand" as Mr. Alex Traub calls it in his book Trump Technique. The name is derived from Odd-evEN.
Slang: down; set;
A player in violation of the laws or regulations. A player who commits an irregularity. Law 12 or Law 72 may be invoked.
1. the strategic plan or attack by the opponents. An offensive play or bid is considered to be an aggressive move as opposed to the defensive play or bid. The term applies to all bridge players at the table.
2. a breach of the Laws.
In duplicate bridge, the account prepared by the director which includes the score for each contestant for each board, his score and rank for the session and for the event.
A system of contract bridge bidding devised and endorsed by a group of leading American authorities in 1931. This official system was in opposition to Mr. Ely Culbertson, although they recognized his credit in making the game of bridge popular. They were Mr. Milton C. Work, Mr. Sidney S. Lenz, Mr. Wilbur C. Whitehead, Mr. Winfield Liggett Jr., and Mr. F. Dudley Courtenay. The Advisory Council included Mr. Shepard Barclay, Mr. Fred G. French, Mr. Henry P. Jaeger, Mrs. Madeleine Kerwin, and Mr. E.V. Shepard. However, after Mr. Ely Culbertson's 8,980 point win over 150 games against Mr. Sidney Lentz in the 1931 so-called Bridge Battle of the Century, the Official System gave way to bidding systems promoted by Mr. Ely Culbertson.
Not having one of the usual or expected distributions.
Off Shape Takeout Double
Also designated as Minimum Off Shape Takeout Double. This is basically a takeout double made with a holding, which does not correspond to the traditional shape or pattern for a takeout double.
Unfavorably located. A card so placed that a finesse, if attempted, will lose.
A conventional method of rebidding after a 2 No Trump response to a Weak Two opening bid by partner, devised by Mr. Harold A. Ogust, with the intention of describing the holding more completely in terms of weakness and strength. Note: variations are listed below.
Benji Acol Variation - This variation has been adopted for the Acol bidding system to show not only the quality of the suit, but also the number of high card points via the responses.
Bogust Variation - This variation is based on the Weak Two bidder opening with either a good 5-card suit with two of the top three honors, or any 6-card suit. In response to the forcing 2 No Trump bid by partner, the rebids of the Weak Two bidder show the length of the suit and the approximate number of Losing Tricks.
Feature Variation - The origin is unknown. This variation, via the responses, determine whether the Weak Two bidder is indeed weak or strong and to discover whether the Weak Two bidder has a specified feature in a desired suit. The indicated honor is generally considered either a Queen or higher.
Honor-Quality Variation - The origin of this variation is unknown. Similar to the Ron Klinger variation, this variation promises a certain number of the top three honors together with the quality of the suit.
Modified Ogust - A variant of the Ogust conventional method developed by Mr. Jeff Goldsmith specifically for a Weak Two opening bid in Hearts.
New Ogust or September - The origin is unknown. A variation of the Ogust conventional system, whereby the rebids are based on the Losing Trick Count method.
Reverse Ogust - A variant of the Ogust conventional method, origin unknown, whereby the meanings of the two bids 3 Diamonds and 3 Hearts are reversed.
Ron Klinger Variation- A variation developed by Mr. Ron Klinger of Australia to indicate via the rebids the number of honors held after a Weak Two opening bid.
OKBridge - The story behind possibly the first online bridge application is included below.
OKbridge, Inc. is an online bridge club dedicated to serving the worldwide community of bridge players by providing superior software and service.
OKbridge began as a by-product of founder Matt Cleggs courtship of Merja, now his wife. The couple met in 1989 when Merja, a native of Finland, came to California to study with a famous geneticist, Matts father. After Merja returned home, Matt took a year off from graduate school to be with her in Finland.
While in Finland, Matt developed an Internet bridge program as a way of playing bridge with his friends back in the US. OKbridge was first released to the public in August 1990 and the idea caught on. The players sent Matt a steady stream of suggestions, many of which were incorporated into the program.
After several years, there were thousands of people from around the world using the OKbridge software. Due to the increasing demands placed on Matts time, he conducted a survey of users in 1993 to determine if they would be willing to pay a subscription fee if he continued to upgrade the software and provide service. The users approved of the idea, and commercial OKbridge was launched in 1994.
Today, OKbridge has more than 18,000 members from over 90 countries, making it the worlds largest member-supported online bridge club.
August 1990 - Version 1.0 of OKbridge released to the public as freeware.
July 1992 - OKbridge becomes the first online service ever to offer duplicate bridge.
Spring 1994 - A knockout team tournament was held online involving sixteen teams from four continents.
June 1994 - Commercial OKbridge was launched to 500 enthusiastic users.
November 1995 - Introduced Windows version of software.
August 1997 - OKbridge becomes first ever online bridge club to be sanctioned by the American Contract Bridge League for the issuance of masterpoints.
October 1997 - First ever online bridge club to offer daily online duplicate tournaments.
November 1997 - Founder Matt Clegg named the International Bridge Press Associations Personality of the Year for his contributions to the game of bridge.
March 1999 - OKbridge inaugurates the first annual Internet World Bridge Championships co-sponsored by OKbridge, the American Contract Bridge League, Bridge World Magazine, and the World Bridge Federation.
July 2000 - Introduced an easy to use Java-based version of the software that can be played from most web browsers.
The origin of this treatment is unknown. After a cuebid of the opponent's suit in the bidding process, which is employed to invite to 3 No Trump, as the final contract, if the partner holds a stopper in the intended suit, the lowest possible bid in an unbid suit shows a partial stopper in the opponent's suit. If this is not possible below 3 No Trump, then a bid suit may be utilized.
Oldest Bridge Clubs
The worlds oldest bridge clubs date back to the era of Whist. The oldest club is the Portland Club in London, England, which was founded before 1815 as the Stratford Club, and named the Portland Club in 1825. The second-oldest is the Hamilton Club in Bala Cynwyd, Pennsylvania, founded in 1887. The third-oldest bridge club is the Continental Club in Amsterdam, The Netherlands, founded in 1889.
Oltbrink Bidding System
This system was devised by and is played by Mr. Sjoert Brink and Mr. Erik Oltmans from The Netherlands. The designation is a combination of the two surnames of the developers. The system is based on the combination of Precision and the Lorenzo Two Bids.
The official designation is The World Teams Olympiad. This is a worldwide team competition at contract bridge, conducted and supervised by the World Bridge Federation and offers an Open and a Ladies event. The competitions have been held every four years since 1960. This event allows every country to field one team in both categories, no matter the size of its individual bridge population provided it is a member of the World Bridge Federation.
This term was applied in the game of bridge in the sense of a contest of skill at contract bridge in which anyone could participate. The first American Bridge Olympic and World Bridge Olympic were conceived, promoted, and sponsored by Mr. Ely Culbertson in 1932.
Omar Sharif World Individual
The largest total monetary prize of $200,000 was offered when the Omar Sharif World Individual bridge tournament was held in Atlantic City, New Jersey between May 7 and May 10, 1990. This was also the first time that the ACBL sanctioned a cash-prize tournament. Mr. Zia Mahmood of Pakistan won first prize of $40,000, Mr. Fred Hamilton won second prize of $20,000, and Mr. P.O. Sundelin of Sweden won third prize of $12,000.
Ombre - Hombre - The Man
This is the designation of a card game and is a trick-taking card game very similar to the modern games of Spades and Hearts. The game itself is in many ways and fashion a direct ancestor of the modern game of bridge. The link is to the website of Mr. Michael Austin, who provides the explanations for actually playing the game in its original version. He also provides the various designations assigned to the cards themselves. It is only with these clarifications that the student can understand the extensive poem titled The Rape of the Lock by Alexander Pope, born May 21, 1688 and died May 30, 1744, in which he describes the game in poetic form.
This particular poem is a mock-heroic poem written by Alexander Pope, first published in 1712 in two cantos, and then reissued in 1714 in a much-expanded five canto version. The poem was based on an incident recounted by Pope's friend, John Caryll. Arabella Fermor and her suitor, Lord Petre, were both from aristocratic Catholic families at a period, in England, when Catholicism was legally proscribed. Petre, lusting after Arabella, had cut off a lock of her hair without permission, and the consequent argument had created a breach between the two families. Pope wrote the poem at the request of friends in an attempt to "comically merge the two". Pope utilises the character Belinda to represent Arabella and introduces an entire system of "sylphs," or guardian spirits of virgins, a parodic version of the gods and goddesses of conventional epic. Pope satirizes a petty squabble by comparing it to the epic world of the gods.
This ombre-related passages of canto III of the Rape of the Lock in English can be read also on the site of Mr. Michael Austin, or the entire canto III can be viewed as a poem in Rape of the Lock on this site with introductory explanations, and elsewhere on the Internet. This particular poem, which is translated into German and which is the Dritter Gesang of Der Lockenraub can be read also on this site in .pdf file format. The German version is longer since it includes also the passages, which do not pertain to or describe the game of Ombre.
The instructional ombre-bridge-related web page of Mr. Michael Austin has also only been preserved and archived on this site for future reference. The graphics are also designed by Mr. Michael Austin and full credit is given him for his enormous effort to provide this information. Reference.

Hansen titled The Original Game of Ombre; How to Play the Spanish Card Game, published in 1967 by Exposition Press, ISBN: B0006BPNNC.
Omnibus Two No Trump Response
The concept introduces a response method for the responder once an immediate fit in a Major suit has been established. The responder must hold game values for this partnership agreement to take effect. Therefore the responder, with game values, will respond first with a bid of 2 No Trump.
Ominibus - Revised and Updated Version
This is a complete version of the employment of the Omnibus 2 No Trump response devised by and contributed by Mr. Marvin French of San Diego, California, United States. It was published in Popular Bridge magazine, June 1978, in The Bulletin of the ACBL, February, 1981, and in the Contract Bridge Forum, February 1982. It is included in Bridge Conventions Complete, by Amalya Kearse. This is a .pdf file and will be automatically opened by your browser in a new window.
This is a version of the employment of the Omnibus 2 No Trump response devised by and contributed by Mr. Marvin French of San Diego, California. It was first published in the magazine Popular Bridge in 1977. The advantages of this conventional method are: 1. a responding No Trump holding of 16-18 high card points can be shown at a low level when slam is a possibility; 2. some suit contracts normally played from opener's side may be played from the side of the No Trump bidder, plus other advantages. This is a .pdf file and will be automatically opened by your browser in a new window.
A nationwide French tournament, which was first played in 1963. The organizer was Irene Bajos de Heredia. Special decks with perforated edges were distributed to all playing centers, so that the players themselves could select the 13 cards needed for each deal by inserting a metal pin in the appropriate hole. Scoring was on a basis similar to a Par Contest, with awards for good and bad results in bidding and play according to the decisions of an expert panel.
Slang: onside; favorably located.
Indicating the amount of a part-score, as "60-on" or having a partscore of 60.
A bid at bridge contracting to win one odd trick, the book of six tricks plus one trick.
One Club Artificial and Forcing
This method was played in a variety of forms, but the earliest form used in contract bridge was devised by Mr. Harold S. Vanderbilt in his Club Convention, although Mr. Robert F. Foster advocated a similar concept in the auction.
One Club System
A bidding method based on an artificial 1 Club opening. There are several systems which still include this feature: Bangkok Club, Blue Team Club, Canary Club, Carrot Club, French Club, Little Roman, Marmic, Orange Club, Precision, Relay, Roman, Roth Club, Simplified Club, Trefle Squeeze, Vanderbilt, Vienna.
One Diamond Example Opening Bids
These opening bids were developed and devised by Mr. Glen Ashton of Nepean, Ontario, and included multiple interpretations for the 1 Club opening bid. If the first response is 1 Diamond, then the responder shows interest and requests additional information regarding the true nature of the holding. Any Major suit response is considered natural. The No Trump range is considered to be weak and the 2 No Trump opening shows a distributional holding in the Minor suits. Below is the bidding system outlined by the author in an email message dated December 6, 1993.

As an example of the type of system one can have with the new all purpose 1 Diamond ACBL rule (note that only key responses and rebids will be given): (In Kaplan notation, M=major, m=minor)
1 Club: shows either:
a) 4 Spades or 3 Spades with singleton Heart, and 9-17 HCPs; 9-11 HCPs if balanced
b) balanced hand, 15 or more HCPs, can have five card Major
c) hand with no 4-card Major (and not 3-1 in Majors), 15+ or more HCPs
d) 18 or more HCPs, with no 5-card Major
e) 20 or more HCPs, any shape
Most often hand type a is held.
After 1 Club:
1 Club - 1 Diamond asks:
1 Heart: 18 or more HCPs, responder usually bids 1 Spade over 1 Heart
1 Spade: hand type a)
1 NT: 15 to 17 HCPs, balanced
2 Clubs: 15 to 20 HCPs, long Clubs, no 4-card Major
2 Diamonds: 15 to 18 HCPs, long Diamonds, no 4-card Major
2 Major suit: 18 to 21 HCPs, 4-card Major and longer Minor suit
2 NT: 23 to 24 HCPs, balanced
3 any suit: 19 to 23 HCPs, 4-4-4-1, any singleton
After 1 - 1 - 1 - 1 :
1 NT: 18 to 20 HCPs balanced
2 Clubs: game forcing, any shape
2 Diamonds: 18 to 21 HCPs with Diamonds, no 4-card Major
2 Major suit: non-forcing, 20 or more HCPs, 5-card suit or longer
2 NT: 21 to 22 HCPs
3 Minor suit: non-forcing, 20 or more HCPs, long Minor suit
1 -1 : 5-card or longer Spade suit
1 - 1 : 4-card or longer Heart suit
1 Diamond: 9 to 17 HCPs and four Hearts or three Hearts and a singleton Spade, 9 to 11 HCPs if balanced. 1 Diamond - 1 Heart shows three or four and is forcing,
1 Diamond - 2 Hearts is to play opposite 9 to 14 HCPs.
1 Major suit: 5-card suit or longer, 10 or more HCPs
1 NT: 12 to 14 HCPs, balanced, may have 2-2-5-4 or 2-2-4-5
2 Minor suit: 6-card suit or longer, 10 to 15 HCPs, no 4-card Major suit
2 Major suit: weak
2 NT: 5-5 in the Minor suits, 12 to 14 HCPs
3 Clubs and above: the usual
One Diamond Negative Response to One Club
In most bidding systems, which use an artificial opening of 1 Club as a forcing bid, a response of 1 Diamond is employed to deny certain values, and in some partnership understandings, denies also a certain point count, and in other partnership agreements, denies a certain number of controls.
One Heart Opening Transfer to One Spade - 1 Heart Opening Transfer to 1 Spade
The origin of this conventional opening is unknown. An opening bid of 1 Heart transfers the partner to the Spade suit either or the one level or on the two level depending on whether the immediate opponent intervenes with an overcall of a suit or No Trump. If the opponent makes a call of a double, then the partnership treats this action as not having occurred and is ignored. This conventional method is presented in the form of a .pdf file by ACBL. This method is only archived and preserved on this site, also in .pdf file format, for future reference.
One Hundred Honors
The honor cards, four of the five trump honors in one hand, entitling their holder's side to a bonus of 100 points. Scored in rubber bridge.
One Hundred Fifty Aces
All four Aces in one hand at No Trump, entitling the holder's side to an honor bonus of 150. Scored in rubber bridge.
One Hundred Fifty Honors
All five trump honors in one hand, entitling the holders side to an honor bonus of 150. Scored in rubber bridge.
One No Trump Opening
Three elements are applied in making this bid; Strength, Distribution, and Location of Strength. The point range is different with many partnerships ranging anywhere from 10 to 18 high card points. Several partnerships have agreed to use one range of No Trump for a vulnerable situation and another range of No Trump if not vulnerable.
One No Trump Overcall
A direct overcall of 1 No Trump traditionally shows a balanced distribution and a No Trump range in standard methods, and presumably a stopper in the suit bid by the opponent.
One No Trump Rebid by the Opener
The rebid of 1 No Trump by the opener shows an opening hand and also limits the strength of his holdings to a certain point count.
One No Trump Response
A bid of 1 No Trump by the responder after his partner has opened the auction, which limits his hand to a certain point count, generally 6-9/10 high card points, and which shows less than minimum support for his partners suit.
One No Trump Forcing Response to a Major Opening
This response is applied on a wide range of holdings including many which would qualify in standard systems for a single raise or a response at the Two Level in a new suit.
One No Trump Response to a Minor Suit
Several bidding systems have established a range of 8-10 high card points as the requirement for a response of 1 No Trump to an opening of 1 Club. In the Goren system, a range of 9-11 high card points are necessary. The reason is that a weaker holding can normally find another bid, even a suit bid on the One Level, which could also be a 1 Diamond Waiting Bid. However, most bidding systems require a 1 No Trump response after a 1 Diamond opening, which is treated also as a forcing opening. Using the Kaplan-Sheinwold bidding system, the requirement is that a response of 1 No Trump promise 5-8 high card points.
One trick more than six. A bid or one odd is a bid to win seven tricks.
1 No Trump Opening
This presentation provides a basic understanding of the parameters for opening a 1 No Trump at the bridge table. This presentation in no way pretends to exhaust all of the principles applied by bridge partnerships around the world based on any particular position at the table, on the state of vulnerability, on the foundations of certain bidding systems, and on whether the partnership agrees to employ multiple ranges depending on the circumstances at the bridge table
The bid of a higher-ranking suit at the one level after partner's opening bid in a different suit. The standard minimum strength is 6 high card points, but some partnerships have lowered this minimum to 3 high card points and distributional pattern. The maximum is 17 high card points in Standard American and 15 high card points in Acol, a range which is just below a jump shift.
A term for the Ace.
A hand including a suit with at least six cards and no more than three cards in any other suit.
This is a hybrid between a squeeze and a throw-in. Most of these forms of squeezes involve two or more suits.
One-Under Opening Bid
In other modifications of Weak Opening Systems, a feature called the One-Under Opening Bid was used. The opening bid of 1 Diamond, for example, meant that the bidder in truth is bidding 1 Heart, and the opening bid of 1 Heart actually meant the opening bid of 1 Spade, and so on.
Many advances have been made with new and newer software programs, which allow the bridge player to play a game of bridge interactively with a device on indeed online globally with other live bridge players. The development of such programs has been an integral part of the game of bridge and such devices have added to the enhancement, expediency, and enjoyment of the game.

Opening Bids of Bidding Systems
In the evolution of the game of bridge, opening bids played an important part in laying the foundation stone for many bidding systems. These opening bids were developed in different countries and have gained some popularity nationally and/or within the bridge community, and some have been practically forgotten. However, the developers spent many hours of research, many hours of their time to develop some sort of standard for the opening bids, which allowed a practical if not standard bidding system to become established.
The original call made by the dealer to initiate the auction.
The lead card to the first trick, made by the player to the left of the declarer before dummy's cards are exposed. The opening lead is chosen and considered beforehand under many aspects since the lead could eventually defeat the contract. The card must be chosen based upon the bidding, visualizing the holding of the dummy and the declarer based upon the auction, in which information has been exchanged. There are also standard leads against suit contracts as opposed to leads against No Trump contracts and against slam contracts.
The player, to declarer's left, who leads to the first trick.
Opening 1 No Trump
Everyone enjoys opening a 1 No Trump, but what determines this bid? Believe it or not, the range for opening 1 No Trump can be as little as 10 high card points and can reach 18 high card points. This is a large range. Before a player opens 1 No Trump, there are several things to consider. There are some bridge players who alternate their No Trump range depending on the vulnerability and position at the table. Generally speaking, at favorable vulnerability the range is 12-14 high card points and at unfavorable vulnerability the range is 15-17 high card points.
Opening Suit Bid
Regarding the opening of 1 Club, 1 Diamond, 1 Heart, or 1 Spade, the range assumed is the normal range between 12 to 21HCPs. On the strongly distributional hands, the range can sink to 10HCPs. The range can be more than 20HCPs with unusual distribution of 4-4-4-1, which are unsuitable for No Trump openings.
An event of duplicate competition between pairs of players without regard to sex or masterpoint range. If the event is scheduled for two or more sessions, there is a qualifying and a final event, with those eliminated eligible to compete in a consolation event.

The origin of the optional double is unknown and has been modified since the first concept. The optional double, which is generally considered a cooperative double, is used to show a specific shape and a minimum of points to defeat the final contract of the opponents in all probability, and promises support for the partner for any unbid suit. This optional double provides the advancer with the option of either passing for penalty or continuing to compete.
1. a term for alternative play possibilities available to the declarer.
2. a term for alternative actions available to a player under certain circumstances after an irregularity by the opposing side. For example, an opening lead by the wrong defender gives the declarer four options from which to choose. See Laws 53 and 54.
