Standard American
Standard American is a bidding system for the game of bridge widely used in North America and elsewhere. Owing to the popularization of the game by Charles Goren in the 1940s and 1950s, its early versions were sometimes referred to simply as 'Goren'. With the addition and evolution of various and , it is now more generally referred to as Standard American. It is a bidding system based on five-card majors and a strong notrump; players may add conventions and refine the meanings of bids through partnership agreements summarized in their . One standardised version, SAYC (Standard American Yellow Card), is widely used by casual partnerships and in online bridge. Role of bidding systems The purpose of bidding during the auction phase of each deal is to disclose information which one's partner may employ in order to arrive at an optimal contract while concurrently contending with the opponents' attempts to do likewise.

Bidding System
A bidding system in contract bridge is the set of agreements and understandings assigned to calls and sequences of calls used by a partnership, and includes a full description of the meaning of each treatment and convention. The purpose of bidding is for each partnership to ascertain which contract, whether made or defeated and whether bid by them or by their opponents, would give the partnership their best scoring result. Each bidding system ascribes a meaning to every possible call by each member of a partnership, and presents a codified language which allows the players to exchange information about their card holdings. The vocabulary of is limited to 38 different calls - 35 level/denomination ''bids''A bid consists of two components — the level in range of 1-7, and one of five denominations: clubs (), diamonds (), hearts (), spades () and notrump (NT) plus ''pass'', ''double'' and ''redouble''. Any bid becomes a contract if followed by three successive passes, therefore ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stayman
Stayman is a bidding convention in the card game contract bridge. It is used by a partnership to find a 4-4 or 5-3 trump fit in a suit after making a one (1NT) opening bid and it has been adapted for use after a 2NT opening, a 1NT overcall, and many other natural notrump bids. The convention is named for Sam Stayman, who wrote the first published description in 1945,"A New Notrump Convention", Samuel Stayman, ''The Bridge World'', June 1945. but its inventors were two other players: the British expert Jack Marx in 1939, who published it only in 1946, and Stayman's regular partner George Rapée in 1944. *3 = --> *3 = ? *3NT = to play After a transfer, accept it with any 4333, bid 3NT with only two trumps, otherwise bid 4M. 1NT - 2; 2/2NT - 3 = Stayman *3 = 4M333 *3 = 4, not 4333 *3 = 4, not 4333, not 4 *3NT = no 4M 1NT - 2; 2/2NT - 3, 3 *3 = 4, not 4 *3 = 4, not 4 *3NT = to play *4 = bid your 4 card Major An alternative, simpler version of five-card Stayman is: ...

Unusual Notrump
In the card game of bridge, the unusual notrump is a conventional showing a two-suited hand. It was originally devised by Al Roth in 1948 with Tobias Stone, to show the minor suits after the opponents opened in a major. The convention concept is now generally extended to show the "two lowest unbid" suits. Thus, over 1, 2NT shows diamonds and hearts; and over 1, it shows clubs and hearts. In addition to succinctly describing the hand to the partner, it deprives the opponents of bidding space, i.e. it has a preemptive effect. A drawback is that it provides the opponents with information about the strength and distribution of the overcaller's hand, potentially enabling improved declarer play should they secure the contract. History In his seminal 1953 book,. The book is characterized as "An influential book, that suffers somewhat from a lack of clarity. It provides a structure that was lacking in Goren, with better definitions for bidding actions...". The Roth-Stone System, Alvin ...

Michaels Cuebid
The Michaels cuebid is a conventional bid used in the card game contract bridge. First devised by Michael Michaels of Miami Beach, FL, it is an 's cuebid in opponent's opening suit and is normally used to show a two-suited hand with at least five cards in each suit and eight or more points. After the opponents have opened at the one-level, the overcaller bids the same suit at the two-level; the two normal cases are: #Over an opponent's minor opening, a cuebid shows both majors. For example, 1 – 2 shows hearts and spades. #Over an opponent's major opening, a cuebid shows the other major and a minor suit. For example, 1 – 2 shows hearts and either clubs or diamonds. Partner can make a 2NT relay bid to request partner to bid his minor suit, or a 3 pass-or-correct bid. Partnerships who have incorporated Michaels cuebids amongst their agreements usually also play the unusual notrump convention. Requirements Point count requirements vary and are a matt ...

Fourth Suit Forcing
Fourth suit forcing (also referred to as fourth suit artificial; abbreviated as FSF or 4SF) is a contract bridge convention that allows responder to create, at his second turn to bid, a forcing auction. A bid by responder in the fourth suit, the only remaining unbid suit, is artificial indicating that responder has no appropriate alternate bid, remains interested in the potential for a game contract and asks opener to bid again to show additional features. Opener responds to the ''fourth suit forcing'' by (in prioritised order): # Raising responder's first bid suit with 3-card support, # Bidding notrump with values in the fourth suit, # Raising the fourth suit with four cards in that suit, # Making the most natural rebid possible, lacking any of the above. Fourth suit forcing is minimally forcing for one round and usually forcing to game - partnership agreement is required. Whether or not the convention is applicable if the fourth-suit bidder is a passed hand is also a matter of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Negative Double
The negative double is a form of takeout double in bridge. It is made by the responder after their right-hand opponent overcalls on the first round of bidding, and is used to show shortness in overcall's suit, support for the unbid suits with emphasis on majors, as well as some values. It is treated as forcing, but not unconditionally so. In practice, the negative double is sometimes used as a sort of catch-all, made when no other call properly describes responder's hand. Therefore, a partnership might even treat the negative double as a wide-ranging call that merely shows some values. Usage Using the modern negative double convention, it is understood that a double over an initial overcall is conventional, and ''not'' for penalties (but see Playing for penalties). For example, using this convention, the following doubles would be regarded as negative, not for penalty: *1 – (1) – Dbl *1m – (1M) – Dbl *1 – (1) – Dbl *1M – (2m) – Dbl In understandings regarding nega ...

Jacoby 2NT
Jacoby 2NT (Swedish: ''Stenberg 2NT'') is a bridge convention in which a bid of 2NT over partner's opening bid of one heart (1) or one spade (1) shows a hand with both * opening strength or better - normally at least 12 HCP or a hand meeting the " Rule of 20" criteria, and * at least four-card support for opener's major suit. The 2NT response is forcing to at least game in opener's major suit. If the partnership also plays splinter bids, the Jacoby 2NT response tends to deny the shape for a splinter (i.e., no singleton or void). However, it might be the best alternative as prelude to possible slam exploration with unbalanced support in a holding stronger than the agreed range for a splinter bid. Origins In most bridge literature, the convention is said to have been developed by Oswald Jacoby. However, credit for its development has also been attributed to Leo Baron. Opener's Rebids Over a Jacoby 2NT Response With a balanced hand, opener rebids as follows: ACBLbr>"Bidding Tool ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blackwood Convention
In the partnership card game contract bridge, the Blackwood convention is a bidding convention developed by Easley Blackwood in 1933 and still widely used in the modern game. Its purpose is to enable the partnership to explore its possession of aces, kings and in some variants, the queen of trumps to judge whether a slam would be a feasible contract. The essence of the convention is the use of an artificial 4NT bid made under certain conditions to ask partner how many aces he has; responses by partner are made in step-wise fashion to indicate the number held. Blackwood's original summary After developing the concept in 1933, Easley Blackwood submitted an article proposing his slam-seeking convention to ''The Bridge World'' magazine but it was rejected.Blackwood (1949), page 192. Nevertheless, it gained awareness and use amongst players and was written about by several authors. In his own first publication on the convention in 1949, Easley Blackwood comments on the entries in books b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Convention Card
In contract bridge and particularly in duplicate bridge a convention card is a summary of the conventions and treatments that a particular pair is using. The Laws of Duplicate Bridge specify that "Each partnership has a duty to make available its partnership understandings to opponents before commencing play against them." In games regulated by the American Contract Bridge League The American Contract Bridge League (ACBL) is a governing body for contract bridge in the United States, Canada, Mexico, and Bermuda. It is the largest such organization in North America having the stated mission ''"to promote, grow and sustain th ... (ACBL), this is generally done using a form with a standard format. The ACBL ''General Conditions of Contest'' specify that "Each member of a partnership must have a completely filled out convention card available for the opponents." Convention card formats may vary by jurisdiction. There are also various computer programs which a player may use to create a ...

Gerber Convention
Gerber is a contract bridge convention devised by William Konigsberger and Win Nye from Switzerland who published it in 1936; John Gerber of Texas introduced it to North America in 1938 where it was named after him. It is similar to Blackwood but uses 4 instead of 4NT as a relay (asking) bid to inquire about the number of aces held by partner. A further relay bid may follow to inquire about the number of kings held. Gerber is used primarily after notrump openings, responses, and rebids, making it a complement to Blackwood rather than a replacement. Some club players also use it after suit bidding, but most experts do not recommend this. Purpose Because bidding and making a slam or grand slam contract in bridge gains significant bonus scoring points, partnerships will strive to bid them whenever their combined card assets are deemed sufficient. Knowing the number of aces and kings jointly held is usually crucial to this decision and Gerber is one of several bridge conventions us ...
