These terms are used in contract bridge, using duplicate or rubber scoring. Some of them are also used in whist, bid whist, the obsolete game auction bridge, and other trick taking games. This glossary supplements the Glossary of card game terms. In the following entries, boldface links are external to the glossary and plain links reference other glossary entries.

3014 or 3014 RKCB A mnemonic for the original (Roman) response structure to the Roman Key Card Blackwood convention. It represents "3 or 0" and "1 or 4", meaning that the lowest step response (5) to the 4NT key card asking bid shows responder has three or zero keycards and the next step (5) shows one or four. 1430 or 1430 RKCB A mnemonic for a variant response structure to the Roman Key Card Blackwood convention. It represents "1 or 4" and "3 or 0", meaning that the lowest step response (5) to the 4NT key card asking bid shows responder has one or four keycards and the next step (5) shows three or zero. 1RF One round force. 2 under preempts A 2 or 3 level conventional opening bid made two steps below the opener's suit: for example, 2 to show a weak two bid in spades or 3 to show a three level preempt in hearts. If 2 is a strong, artificial force, 2 is natural. 4SF Fourth suit forcing. 8421 Counting points by way of 8421 means counting an ace for 8 points, a king for 4, a queen for 2, and a jack for 1 point. For example, when a bid is interpreted as "5 8421 HCP in S", this means the bidder is expected to have 5 or fewer points in spades, counting an ace as 8 points, etc.

Kaplan–Sheinwold (K–S) A bidding system that uses five card majors and the weak notrump. Keycard Blackwood, or Key Card Blackwood (KCB) A variant of the Blackwood convention in which five keycards are counted, four aces plus the king of the apparent trump suit, rather than four aces alone. Commonly there is a follow up to ask about the queen of trump ("Queen ask"), effectively the sixth keycard. Kibitzer A spectator who attends a game in person. Kickback An ace asking or keycard asking convention initiated by the first step above four of the apparent trump suit rather than uniformly by 4NT. Thus Kickback saves space when the trump suit is not spades. See Useful Space Principle and Blackwood: Asking bids other than 4NT. Kiss of death At pairs, plus or minus 200. A score of minus 200, down two undoubled and vulnerable, or down one doubled and vulnerable, is a likely bottom against a part score by the opponents. A score of plus 200 from making five odd of a major after stopping in a partial, is a likely bottom against the game contracts bid by other pairs holding the same cards. Knockout (KO), or Knockout Teams A single elimination tournament for teams of four. Routinely each round pairs all of the competing teams in head to head matches—win or lose; no draw or tie. Winners advance to the next round and losers are eliminated. The size of the field, or initial number of competing teams, must be a power of two. Only then, the format generates for each round an even number of teams, which enables a complete set of head to head matches. Minor variants of great practical importance handle fields of any size by incorporating byes (definition 1) or matches with more than two teams (stipulated to have more than one winner, more than one winner, or both). Two major variants are double knockout, in which teams are eliminated after losing two matches, and repechage, in which one match losers drop into a secondary event from which some number of top performers return to the primary event. Knockout squeeze A type of squeeze that operates in part against the defender's trump holding, when the defender threatens to win a plain suit trick and then lead a trump, thus reducing declarer's ruffing tricks. It is usual to call this play a knockout squeeze when the squeezed defender is second to play to the trick, and to call it a backwash squeeze when the squeezed defender is fourth to play. Kock–Werner Redouble A rescue mechanism employed when partner's bid is doubled for penalties. Invented by Rudolf Kock and Einar Werner of Sweden. See also SOS Redouble.

MacGuffin A defensive card that, if retained, is a liability on one line of play, but that, if played, will be missed on another line of play. The term may be derived from the filmic plot device of the same name. Major penalty card A card that is exposed by a defender prematurely and through intentional play; or, an honor card that is exposed prematurely even if accidentally. A major penalty card remains face up on the table to be played at the first legal opportunity, including as a discard. Contrast Minor penalty card. Major suit The heart suit and the spade suit are major suits, often referred to simply as the majors. Declarer scores 30 points for each trick taken in an undoubled contract with a major suit as trump. Because game requires at least 100 points for tricks bid and made, both 4 and 4 (or 2 doubled and 2 doubled) constitute game contracts. Contrast Minor suits. Major tenace The highest and the third highest remaining cards in a suit, held in the same hand. For example, the AQ before spades have been played. Tenaces define the structure of finesses. See minor tenace. Make (Verb) To take at least as many tricks as a contract calls for. Frequently used in the past tense of the verb, i. e. Made. Mama–Papa (Adjective) An unsophisticated game, approach to bidding, or line of play. Marionette Bid (Noun) A type of relay bid in which the cheapest response is expected nearly all the time, thus similar but not identical to a puppet bid. Name derives from "a puppet with strings." Marked To be known to hold a particular card: "He was marked with the Q." Marked finesse A finesse for a card that evidently lies with a particular opponent. Master The highest card of a suit that is yet to be played. Masterpoints Units awarded, usually by national organisations, for successful performance in a bridge tournament. Match A series of hands played by two teams in knockout events. One pair from each team sits North South at one table and the other pair sits East West at the other table. Matchpoints A type of scoring in duplicate bridge. A pair's score on a given board is one matchpoint for every pair they outscored and one half matchpoint for every pair they tied. (Outside the US these awards are often doubled, so as to avoid the award of fractional matchpoints.) See comparative scoring. Matrix The layout of the cards that play pivotal roles in certain endplays, most typically squeezes. Maxims A maxim of bridge is a brief expression of a general principle of the game. Most Bridge maxims have some validity but none are true in all circumstances. Maximal overcall double By prior agreement, a game invitational double of an overcall that leaves no room for a bid, when a bid would invite game. For example, after 1 – (2) – 2 – (3) there is no room below 3 for a game invitation (and a bid of 3 itself would be taken as merely competitive), so a double is used as a game invitation. McKenney See Suit preference signal. Menace A card that requires an opponent to retain a higher card in the same suit, as a guard. The term is typically used of squeeze play. Merrimac coup The deliberate sacrifice of a high card to remove a vital entry to an opponent's hand, usually the dummy. Named for a ship sunk during the Spanish–American War, to block the entrance to a harbor. Sometimes confused with, and spelled as, the Merrimack, the American Civil War ship that fought the Monitor. See Deschapelles coup. Michaels cue bid By prior agreement, an immediate cue bid in the suit of an opponent's opening bid, such as 1 – (2), for two suited takeout. The cue bid of a minor suit shows length in both major suits. The cue bid of a major suit typically shows length in the other major suit and in an unspecified minor suit. MiniBridge A simplified form of contract bridge designed to expose newcomers to declarer and defensive playing techniques without the burden of learning a detailed bridge bidding system. Minor penalty card A card below the rank of an honor card that is exposed by a defender prematurely but accidentally, via mishap. A minor penalty card remains face up on the table until played. The minor penalty card must be played before any other card below honor rank in the same suit; however, an honor in the same suit may be played before the minor penalty card is played. Contrast Major penalty card. Minor suit The club suit and the diamond suit are minor suits. Declarer scores 20 points for each trick taken in an undoubled contract with a minor suit as trump. Because game requires at least 100 points for tricks bid and made, both 5 and 5 (or 3 doubled and 3 doubled) constitute game contracts. Contrast Major suits. Minor tenace The second highest and the fourth highest (or lower) remaining cards in a suit, held in the same hand. For example, the KJ before spades have been played. See major tenace. Mirror Identical hand distributions: "North and South had mirror distributions." Misbid A bid that fails to describe the hand properly. Often a misdescription of a hand's shape, as distinct from an overbid or underbid. Misfit Two partnership hands, neither of which can support the other's long suit. For example, a red Two suiter opposite a black Two suiter constitutes a misfit. Mitchell movement A pairs tournament movement in which the pairs sitting in one direction (usually North South) stay in the same seats throughout, but after each round the pairs sitting in the other direction (usually East West) move to the next higher numbered table, and the boards are moved to the next lower numbered table. Unless an arrow switch is performed, the effect is to create two events, a "North South" contest and an "East West" contest, with separate winning pairs, though a single winner can still be determined by comparing percentage results. Mixed 1) Of an event: contested by pairs or teams in which every pair comprises one male and one female player. 2) In the auction: A mixed raise is, by agreement, a jump cue bid of opener's suit in support of partner's overcall. It tends to show four card support for partner's suit and the strength of a good single raise. In 1 – (1) – 1 – (3), 3 is a mixed raise. Morton's fork coup A play that forces the defense to choose between taking a high card that will establish extra winners for declarer, and ducking the trick, after which the high card cannot be cashed. Movement In a tournament, the scheme for the progression of players and boards from table to table, arranged so that a pair does not play the same boards twice, or meet the same opponents twice etc. The most common movements for pairs tournaments are Howell and Mitchell. Moysian fit A 4–3 trump fit, or a contract with such a trump fit. Named after The Bridge World editor Alphonse "Sonny" Moyse Jr, who wrote and published a variety of articles that promoted the virtues of such fits or contracts, some bidding styles designed to locate them, and some techniques for playing them well. MUD Acronym of "Middle, Up, Down", a lead convention which describes the sequence in which cards from a holding of three low ones (all less in rank than the 10) are played. Muiderberg convention A weak two bid showing five cards in a major and at least four cards in another suit. Multi An ambiguous opening bid of 2 that promises one of several different types of hand. Originally entitled "multicoloured 2 Diamonds".

Quack A portmanteau of queen and jack. Used in situations where it does not matter whether the queen or the jack is held or played, as well as to emphasize that it does not matter. See Principle of restricted choice. Qualifying (Adjective) A session or sessions preliminary to the final of an event. Quantitative 1) Of a bid: A call based, usually, on high card points, rather than a feature such as fit or shortness. A raise from 1NT to 3NT based on a 4–3–3–3 hand with 10 HCP is a quantitative raise. 2) Of scoring: The method of scoring used in rubber bridge or in IMP events. The metric used is the number of points earned on each deal, perhaps adjusted by the IMP scale and victory points. In contrast, comparative scoring is based on the number of pairs that have been out scored. Queen ask, or queen ask In Key Card Blackwood, the cheapest bid over the response to 4NT, to ask responder for the trump queen. Quick tricks In card play, top ranking holdings able to win tricks immediately. Similar in concept to honor tricks in the evaluation of hand strength. Quitted trick A trick whose cards have all been turned face down (duplicate bridge) or gathered in front of the trick's winner (rubber bridge). In rubber bridge, a player may inspect a quitted trick if his side has not yet led to the next trick. In duplicate bridge, a player may inspect a quitted trick only if told to do so by a director. Quotient Points won divided by the sum of points won and points lost, occasionally used to break a tie.

Sac (Slang) Sacrifice. Also, "sack." Sacrifice
(Noun) A contract that was deliberately bid in the expectation of going down, in the hope of a penalty smaller than the opponents' expected score from making a contract they had bid. (Verb) To bid to such a contract. Safety level A level at which the partnership can normally assume, on the basis of the previous bidding, that its contract will succeed. It is the point below which the partnership prefers to explore even higher contracts. Also, "security level." Safety play A play that maximizes the chances for fulfilling the contract (or for achieving a certain score) by avoiding a play which might result in a higher score. Contrast Percentage play, the best play in a suit, whereas a safety play is the best line for the contract. Sandbag (Slang) To bid weakly or pass with good values, in the hope that the opponents will get overboard. Sandwich An overcall made after an opening bid and response by the opponents. The overcall is "sandwiched" between two hands that have each shown strength. Save (Slang) Sacrifice. SAYC Standard American Yellow Card, a particular bidding system or the completed ACBL convention card that represents it. Scientific A style of bidding that attempts to narrowly limit the strength of a partnership's hands, so as to make its bidding more accurate. Scissors coup A loser on loser play meant to break the opponents' communications. Formerly known as 'Coup without a name'. Score, or bridge scoring 1) The numeric result of a deal, session or event. 2) (Verb) Of a card, to win a trick: "The Q scored." Score slip A paper form used to record the result of each deal in a duplicate bridge event when electronic scoring devices are not available. Depending upon the event format, the score slip may be either a pick up slip or a traveller. Scramble 1) To bid to a safer contract. 2) To score small trumps by ruffing, rather than as long cards. Often used of the play of a contract based on a Moysian fit. Screen A device which divides the table diagonally, visually separating partners from each other. Used in higher level competition to reduce the possibility of unauthorized information. Screenmates Opponents who sit on the same side of the screen. Seat Position relative to the dealer: for example, dealer's LHO is said to be in second seat. Second guesser See result merchant. Second hand The player to the left of the player who has led to a trick. Second hand low A precept that advises second hand to play a low card on RHO's lead. See also Third hand high. Section A group of contestants in an event. Seed A ranking assigned to a contestant of relatively high rank. See saw squeeze See Entry shifting squeeze. Semi balanced hand A hand with 5–4–2–2 or 6–3–2–2 distribution. Semi forcing bid A bid which is conditionally forcing: one which requests partner to rebid unless his hand is minimal or sub minimal for his previous bidding. Compare invitation. Sequence 1) The auction, or calls made in the auction. 2) Two or more cards adjacent in rank. Session A period of play during which those entered in an event play designated boards against designated opponents. Set 1) To defeat a contract. 2) The number of tricks by which a contract is defeated ("a two trick set"). Set game In rubber bridge, an agreement that partners will not change at the end of each rubber. Set up Establish. SF Semi forcing. Shaded (Of a call) A call that is not quite warranted by the strength of the hand making it. Shape The distribution of suits in a hand. Shift 1) (Verb) To lead a suit other than the one already played. 2) (Noun) In the bidding, a change of suit, usually said of a jump bid (see jump shift). Shoot To try for an unusually good result by adopting an abnormal line of play, typically at matchpoint scoring. Declarer hopes that the cards are distributed in such a way that a superior line of play will fail. Short club The natural opening bid of 1 when the suit contains three cards or less. Usually employed by players using the five card majors treatment for opening bids when holding a hand with opening values but lacking a five card major. When the hand contains two clubs and three diamonds, an opening diamond bid is preferred. Also, "short diamond." These bids may also be called "prepared minors" – "prepared club" and "prepared diamond", or "better minor" bids. The EBU "Orange Book" recommends the term "prepared club" for bids that show a minimum of three cards, and "short club" where it may only be two cards or less. Short suit 1) In a 13 card hand, a singleton or void suit. 2) In a hand, that suit with the fewest cards. Short suit game try By agreement, a bid of a short side suit after a single raise, hoping to reach game. For example, after 1 – 2, opener might rebid 3 with a singleton or void in clubs. The bid tells partner where high cards will be least useful, indicating duplication of values. It requests partner to take positive action with high card strength outside that suit. Otherwise, the bid requests partner to sign off (in this example, by bidding 3). See help suit game try and game try. Short suit points In hand evaluation, points counted for singletons and voids. Show out Fail to follow suit. Shuffle To mix the cards. Shuffling seldom results in random distributions: in the long run, the cards so mixed rarely match the mathematical expectancies. Side Partnership. Side game A secondary event played simultaneously with the main event. Side suit A suit that is not trump; plain suit. A side suit may nevertheless have significant length: see Two suiter. Signals The conventional meanings assigned to plays made by the defenders in order to exchange information. Also, carding. Signoff bid 1) A bid that requests that partner pass. 2) A call that denies extra values, one that normally results in a pass by partner. Compare non forcing bid, forcing bid. Sign off To make a signoff bid. Silent bidder A sheet, typically of card or plastic, placed in the center of the table during the bidding period, and marked with numeral, suit and other symbols such that a player can indicate a call by tapping on them with a finger, writing implement, or the like. Largely superseded by bidding boxes. Simple squeeze A squeeze against one opponent, in two suits, with the count (definition 3). Single dummy The normal manner of play, with certain knowledge only of one's own cards and dummy's, and without verbal communication between partners. Contrast Double dummy. Singleton A holding of exactly one card in a suit. Sit out A round in a movement during which a pair is idle. That pair is said to "sit out" that round. Skip An irregular feature of a Mitchell movement: typically a move by the East–West pairs of 2 tables up instead of the usual 1, to avoid them playing the same boards twice. Skip bid warning, or skip bid warning A warning to LHO that one is about to make a jump bid that could cause a revealing hesitation or huddle; used only when bidding screens are not in place. The warning is made in one of two ways:
1) When bidding boxes are in use, the red Stop card is placed on the table followed by a bid card; LHO is expected to wait 10 seconds before taking action;
2) When bidding boxes are not in use, the jump bidder announces "I am about to make a skip bid, please wait." and then bids. LHO waits 10 seconds. Slam 1) small slam (or simply, slam): a contract to win at least twelve tricks. 2) grand slam: a contract to win all thirteen tricks. Bidding and making a slam or grand slam scores significant bonus points. Slam try A bid that invites partner to bid a slam. Slot (Slang) The location of a card that is onside. "In the slot" means "Finessable." Slough Discard. Pronounced and sometimes spelled "sluff". Slow Cards that require establishment before they can be cashed. Slow arrival A style of bidding that uses a jump to a contract (to which the previous bidding has already forced the partnership) to show a specific holding. Contrast Fast arrival. Slow rubber A rubber completed in three games. See fast rubber. Sluff See discard. Neo orthography for slough, as used in ruff and sluff. Smack (Slang) Same meaning as crack. Small slam A contract for six odd tricks. Smith signal The Smith signal (also known as Smith echo or Smith peter) is an attitude carding signal in contract bridge showing additional values (or lack thereof) in the first suit led by the defence, while the signal itself is given in the first suit played by declarer. Smolen After opener has denied a four card major in a Stayman sequence, responder's jump to 3M to show four cards in the bid major and five cards in the other major. Smother play An endplay that captures an opponent's guarded trump by means of an overruff, when that card cannot be finessed in the normal fashion. Soft values Lower honors, as distinct from aces and kings. Solid A suit strong enough to run without interruption, or (in the bidding) that requires no fit with partner. Sort To arrange one's cards by suit, and by rank within suit. SOS redouble A conventional redouble that asks partner for rescue from a doubled contract. Its name comes from the Morse code distress signal SOS. Sound A hand that is relatively strong for a call that is contemplated or that has been made. South African Texas A variant of Texas in which 4 and 4 are used as transfers to 4 and 4 respectively. Splinter A singleton or void in a suit other than the trump suit. A hand with both good support for partner's trumps and a splinter can be very powerful offensively—offering control of the splinter suit (by ruffing the first or second trick) and extra trump winners (by ruffing subsequent rounds). When declarer holds either no top honors or the ace and low cards opposite a splinter in the dummy, the combined hands may win several more tricks than the partnership might have expected without awareness of the powerful fit. Splinter bid An unusual jump bid that by agreement shows a fit for partner's last bid suit and a singleton or void in the bid suit. For example, a partnership could treat 4 in response to an opening bid of 1 as a splinter bid, showing a good hand with spade support and a singleton or void club. Compare with Fragment bid. Split 1) (Noun) The distribution in the opponents' hands of the cards in a suit. 2) (Verb) To play one of two touching honors when the lead comes through them. Split menace A menace in squeeze play which depends on values in both declarer's hand and dummy. Split tenace A position where the high cards of a tenace are in opposite hands, e. g. Ax opposite Qx; usually relevant only when a lead by an opponent with the missing honor card (here, the K) would be damaging to his side. Sponsor 1) The organization that puts on a tournament, such as the WBF, the ACBL or the EBU, a regional association, or a club. 2) One who hires partners or teammates to compete in an event. Spot card A card that ranks below the 10. Spread (Slang) Laydown. SPS A Suit Preference Signal, a card played by a defender to show interest in or an entry in a side suit. Squeeze A playing technique that forces the defender to discard a vital card, usually an apparent stopper. Squeeze card A card whose lead forces one or both defenders to discard their guard in a suit. Stack A distribution of cards in defenders' hands that might make the play difficult for declarer. The defenders' trumps, for example, could be said to be stacked if they divide 5–0. Standard American or Standard American Yellow Card (SAYC) A bidding system thought to conform to agreements that an unfamiliar partnership in America would use. Stationary Not called to change seats during the movement being used. Stayman convention A conventional bid of 2 that calls for a 1NT opening bidder to bid a four card major, if one is held, and (usually) 2 otherwise. Many continuations have been devised. Steal To gain an advantage, usually through deception. The theft may be material (e. g., a trick or a contract) or non material (e. g., a tempo). Despite the term steal, deception is entirely legal if it does not involve unauthorized information or concealment of information to which the opponents are entitled. Step In the bidding, the space between one bid and the next highest. See Useful Space Principle. Step bid A bid that conveys information on the basis of the number of steps it uses. Stolen bid A bid that has no correlation to the bidder's hand, aiming to disturb conventions. Stepping stone squeeze A squeeze that forces a defender either to be thrown in to act as a stepping stone to a stranded dummy, or to allow declarer to establish a suit. Sticks and wheels (Slang, chiefly British) An 1100 point penalty. Compare "go for a number". Stiff (Slang, adjective and noun) A singleton. Stop An instruction given to opponents when you make a jump bid, or skip bid. LHO is expected to wait around 10 seconds before calling, so as to avoid communicating information to partner as to how easy his call is to make. See skip bid warning. Stopper A high card (normally, an honor) whose primary function is to prevent the opponents from running a suit in a notrump contract. See also Control. Strain See denomination. Strip 1) To remove safe cards of exit from an opponent's hand. 2) To prepare for a ruff and sluff by removing all cards of a suit (or suits) in a partnership's hands. Strip squeeze A squeeze without the count in which one threat is against a safe exit card. Striped tail ape double A double of a laydown contract made in hope of dissuading the opponents from successfully bidding to a higher, more rewarding contract. The doubler must be prepared to run (like the cowardly ape) to an escape suit if the opponents redouble. Strong club system A set of conventions that uses an opening bid of 1 as an artificial, forcing opening that promises a strong hand. Strong notrump An opening notrump that shows a balanced hand and 15–17 or 16–18 HCP. Contrast Weak notrump. A partnership's choice between the use of a strong notrump or a weak notrump has extensive implications for its entire bidding system. Strong pass system A bidding system that mandates a pass by first (or second) hand to show what other systems would regard as an opening bid. A corollary is that if the next hand also passes, third (or fourth) hand must bid to keep the deal from being passed out. Strong two bid, strong two bid, or Strong Two An agreement to use an opening bid of two of a suit so as to indicate a strong hand and a strong holding in the bid suit. Stub (Slang) Part score. Sucker double (Slang) An ill advised penalty double, such as one based on HCP when the bidding warns of freak distributions. Suit A ranked division of the deck of cards into (in descending rank order) spades, hearts, diamonds and clubs. The suit ranking has a profound effect on the bidding and scoring, but none at all on the play. See also Denomination, Major suit, and Minor suit). Suit preference signal A defensive carding method that signals a preference, or the lack thereof, for a suit other than the suit used for the signal. Superaccept A strongly encouraging response to a transfer, such as a jump completion (e. g., 1NT – 2; 3). Many partnerships use a conventional superacceptance such as 1NT – 2; 2, one step above responder's major, to save room for game or slam exploration, and in conformance with the Useful Space Principle. Support A fit with partner's suit. Support double A double of an overcall that shows a fit for partner's suit, usually distinguished from a direct raise by the length of the suit in responder's hand. Sure trick A trick that in the absence of some irregularity a player must win, such as the ace of trumps. Extended by George Coffin to refer to guaranteed lines of play. Surrogate signals A count or preference signal made in a different suit, usually the suit which declarer is running, to inform partner in beforehand about a critical decision he will have to make later during the play of the hand. Swindle A deceptive bid or play. SWINE A proxi acronym for Sebesfi Woods 1NT Escape. Swing A difference in scores between two tables on a board in a team match. Swinging An aggressive playing style, usually adopted by a pair or team who is behind with some chance to catch the leaders "with a little luck." Swinging players will make plays slightly against the odds that will offer large gains if they succeed. For example, a swinging pair might bid a 60% grand slam on a hand where a small slam should be the normal contract. They might also make close doubles of normal contracts that might go down. Swish (Slang) Three consecutive passes, ending the auction. "3 – swish" means 3 passed out. Swiss, or Swiss Teams A Swiss system tournament for teams of four. Every team plays a series of matches with a series of opponents whose records or standings are as similar as possible when they face each other, without scheduling repeat matches. Typically these are relatively numerous, relatively short matches. For example, of 54 to 56 boards in one day's play: 6, 7, 8, or 9 matches of 9, 8, 7, or 6 boards respectively. Switch To lead a different suit. System see bidding system.

z see Zoom. Zar points An evaluation method to determine if a hand should be opened. It asks to open whenever you have 26 or more Zars, determined by adding the number of cards in the 2 longest suits, plus high card points, plus number of controls (A=2, K=1), plus the difference between the longest and the shortest suit. An additional point is added for the suit if it has 4+ cards. The unsupported honors are diminished 1 point in value. 52 Zar points should produce a NT or major suit game. Zero The lowest score obtained on a deal in a pairs game. Also, bottom. Zia play A specific type of falsecard which creates a losing option to declarer. Zone One of eight geographic zones in which World Bridge Federation member "nations" are grouped for some purposes. The WBF was founded August 1958 by delegates from Europe, North America, and South America, which are now Zones 1 to 3. World championship teams of four competition has been organized zonally even longer: the Bermuda Bowl was contested in one long match between representatives of Europe and North America from 1951 (the second rendition) to 1957; in a three team round robin including the champion of South America for 1958. From 2005 to present, there are 22 teams in zonally organized world championship tournaments. See Senior Bowl: Structure and Zones and nations. Zonal organizations mediate between the world and national levels in some respects. In Zone 1 for instance, the European Bridge League is the zonal organization. Its members are the national bridge federations of 46 countries from Albania to Wales, and geographically from Iceland to Israel. In Zone 2, on the other hand, bridge players are members of the American Contract Bridge League. Zoom (z) In a relay system, the facility to joining into the next level of answers without needing to hear a new relay from partner. Usually, after servant has the highest possible answer for the level s/he is answering, s/he can jump into the next level assuming the captain made a virtual new relay, saving bidding space.
