SAYC
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.

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.

Weak Two Bid
The weak two bid is a common used in the game of contract bridge, where an opening bid of two diamonds, hearts or spades signifies a weak hand, typically containing a long suit. It may be deployed within any system structure that offers a forcing artificial opening to handle hands of (eg) 20+ points, or an expectation of 8 or more tricks. It is form of preemptive bid. The strong call releases any remaining two level openings for pre-empting your opponents. In North America it is commonly used in combination with the strong two clubs convention. Worldwide there are many other variants, the commonest being a strong one club. “Weak Two” refers specifically to an opening bid, not to be confused with the "weak jump overcall". That denotes a similar hand type, made over an opponent's opening bid. Effectiveness 2S is most powerful in terms of pre-emption against your opponents. 2H is less so, easily defended by either a take out double or a 2S overcall. Paradoxically the 2D ...

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 e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hand Evaluation
In contract bridge, various bidding systems have been devised to enable partners to describe their hands to each other so that they may reach the optimum contract. Key to this process is that players evaluate and re-evaluate the trick-taking potential of their hands as the auction proceeds and additional information about partner's hand and the opponent's hands becomes available. Hand evaluation methods assess various features of a hand, including: its high card strength, shape or suit , , fit with partner, quality of suits and quality of the whole hand. The methods range from basic to complex, requiring partners to have the same understandings and agreements about their application in their bidding system. Basic point-count system Most bidding systems use a basic point-count system for hand evaluation using a combination of high card points and distributional points, as follows. High card points First published in 1915 by Bryant McCampbell in ''Auction Tactics'' (page 26), th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 use ...

Jacoby Transfers
The Jacoby transfer, or simply transfers, in the card game contract bridge, is a convention in most bridge bidding systems initiated by responder following partner's notrump opening bid that forces opener to rebid in the just above that bid by responder. For example, a response in diamonds forces a rebid in hearts and a response in hearts forces a rebid in spades. Transfers are used to show a long suit, usually a major, and to ensure that opener the hand if the final contract is in the suit transferred to, preventing the opponents from seeing the cards of the stronger hand. The use of the 2 and 2 (and often 2) responses to an opening 1NT bid as transfers is one of the most widely employed conventions in the game. Less commonly, partnerships may agree to use transfer-style bids in a variety of other situations. History and purpose First described in a series of articles by Olle Willner of Sweden in ''Bridge Tidningen'' in the early 1950s, transfers were popularized for English s ...

Preempt
Preempt (also spelled "pre-empt") is a bid in contract bridge whose primary objectives are (1) to thwart opponents' ability to bid to their best contract, with some safety, and (2) to fully describe one's hand to one's partner in a single bid. A preemptive bid is usually made by ''jumping'', i.e. skipping one or more bidding levels. Since it deprives the opponents of the bidding space, it is expected that they will either find a wrong contract (too high or in a wrong denomination) of their own, or fail to find any. A preemptive bid often has the aim of a ''save'', where a partnership bids a contract knowing it cannot be made, but assumes that (even when doubled), the penalty will still be smaller than the value of opponents' bid and made contract. Scoring context The tables at right help to illustrate the limits of the scoring advantage to be gained in duplicate bridge by preempting or sacrificing when the opponents may be successful in making a game contract.

List Of Bridge Books
''Bridge'', or more formally ''contract bridge'', is a trick-taking card game of skill and chance played by four players. This article consists of lists of bridge books deemed significant by various authors and organizations. History Books on bridge and its predecessor games have spanned centuries with the earliest known popular book on the subject of Whist having been published by Edmond Hoyle in 1742 or 1743. The timelines in the evolutionary path to modern contract bridge books are generally as follows: * 17th century: the emergence of Whist from earlier games such as Ruff and Honours and Triumph * 18th and 19th centuries: Whist is widely played with many variants in scoring methods; similar games such as Vint and Khedive are also played * 1886: Evidence that Bridge-Whist has emerged with John Collinson's four page pamphlet entitled Biritch, or Russian Whist.

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 book ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Goren
Charles Henry Goren (March 4, 1901 – April 3, 1991) was an American bridge player and writer who significantly developed and popularized the game. He was the leading American bridge personality in the 1950s and 1960s – or 1940s and 1950s, as "Mr. Bridge" – as Ely Culbertson had been in the 1930s. Culbertson, Goren, and Harold Vanderbilt were the three people named when ''The Bridge World'' inaugurated a bridge "hall of fame" in 1964 and they were made founding members of the ACBL Hall of Fame in 1995. According to ''New York Times'' bridge columnist Alan Truscott, more than 10 million copies of Goren's books were sold. Among them, ''Point-Count Bidding'' (1949) "pushed the great mass of bridge players into abandoning Ely Culbertson's clumsy and inaccurate honor-trick method of valuation." Goren's widely syndicated newspaper column "Goren on Bridge" first appeared in the Chicago Tribune August 30 1944, p.15. Early years Goren was born in Philadelphia, Pennsylvania, to Ru ...
