Lebensohl
Lebensohl is a contract bridge convention whose variants can be used in the following situations: * by responder after an opponent's overcall of a one notrump (1NT) opening bid in order to compete further in the auction without necessarily committing the partnership to game. * after opponents' weak-two bids and * in responding to a reverse by partner. Origins and spelling The origins of the convention are unknown and various views about its spelling have ensued. The Official Encyclopedia of Bridge (OEB) first listed LEBENSOHL in its third edition published in 1976 and attributed its design to George Boehm; the fourth OEB edition, under the entry LEBENSOLD, states that George Boehm first described the convention and that Boehm had wrongly attributed it to Ken Lebensold; the fifth and sixth editions state likewise but under LEBENSOHL. In the seventh edition and for the first time, the OEB notes "Uniquely amongst bridge conventions, it should arguably be spelled with a lowercase firs ...

Rubensohl
Rubinsohl (also referred to as Rubensohl) is a bridge convention that can be used to counter an opponent's intervention over a 1NT opening bid. After opponent's two-level overcall, all bids starting from 2NT are transfer bids to the next strain. Origins The concept was introduced by Bruce Neill of Australia in a Bridge World magazine article in May 1983. Because he had based his concept on earlier work by Jeff Rubens on Rubens Advances and on Lebensohl, Neill named the treatment Rubensohl. However, from the fifth edition in 1994 onwards, The Official Encyclopedia of Bridge notes that Ira Rubin of the United States had devised similar methods earlier to replace Lebensohl and "...so Rubinsohl seems the appropriate name". Applications When playing Rubinsohl, the following applies after an opposing 2 (natural) overcall over partner's 1NT opening: 1NT - (2) - ?? :dbl : penalty :2/ : to play :2NT : transfer to 3 :3 : transfer to opponent's suit -> asks for four card major :3 : transf ...

Blackout Convention
Blackout is a bridge convention for responding to a reverse bid after a one-over-one beginning, whereby the responder can show whether or not he has better than a minimum response. Responder makes the cheapest bid from either the fourth suit or 2NT to show a hand that has no game interest. All other bids show reasonable hands, generally in the eight point range and are game-forcing. The objective of Blackout is to allow the constructive game-going hands to keep the bidding level low and give more room for the strong auctions that may lead to slams. The convention is also known as ''Wolff Over Reverses''. Responder then rebids as follows: * A rebid of his own suit shows five or more cards in the suit and is for one round, but does not promise any extra strength. * The cheapest bid of the fourth suit is forcing and 2NT shows exactly four cards in his own suit and a minimum hand for his . * The non-cheapest bid of the fourth suit is forcing and 2NT shows exactly four cards in his o ...

Contract Bridge
Contract bridge, or simply bridge, is a trick-taking card game using a standard 52-card deck. In its basic format, it is played by four players in two competing partnerships, with partners sitting opposite each other around a table. Millions of people play bridge worldwide in clubs, tournaments, online and with friends at home, making it one of the world's most popular card games, particularly among seniors. The World Bridge Federation (WBF) is the governing body for international competitive bridge, with numerous other bodies governing it at the regional level. The game consists of a number of , each progressing through four phases. The cards are dealt to the players; then the players ''call'' (or ''bid'') in an auction seeking to take the , specifying how many tricks the partnership receiving the contract (the declaring side) needs to take to receive points for the deal. During the auction, partners use their bids to also exchange information about their hands, including o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Official Encyclopedia Of Bridge
''The Official Encyclopedia of Bridge'' (OEB) presents comprehensive information on the card game contract bridge with limited information on related games and on playing cards. It is "official" in reference to the American Contract Bridge League (ACBL) which authorized its production and whose staff prepared and/or supervised its various editions. The first edition of the ''Encyclopedia'' was published in 1964 with Richard Frey as Editor-in-Chief; it was the only one with an edition revised for an overseas market (''The Bridge Players' Encyclopedia'', 1967). The seventh and latest edition was published in 2011 following intermediate editions in 1971, 1976, 1984, 1994 and 2001. The Executive Editor for the first six was Alan Truscott, bridge editor of ''The New York Times''. For the fourth through sixth editions, Henry Francis succeeded Frey as Editor-in-Chief. Frey and Francis were also successive editors of the ACBL monthly membership magazine. Numerous contributing editors to t ...

The Bridge World
''The Bridge World'' (TBW), the oldest continuously published magazine about contract bridge, was founded in 1929 by Ely Culbertson. It has since been regarded as the game's principal journal, publicizing technical advances in bidding and the play of the cards, discussions of ethical issues, bridge politics and leading personalities, and reports of major tournaments. Culbertson edited TBW (assisted by a staff of well known writers and players such as Josephine Culbertson, Alfred Sheinwold, Samuel Fry Jr., Richard L. Frey, Albert H. Morehead, and Alphonse "Sonny" Moyse Jr.) until 1943. Morehead then became editor and continued until 1946, when Moyse took over. The McCall Corporation purchased TBW in 1963, and subsequently sold it to Edgar Kaplan. Kaplan became editor and publisher in late 1966; his first issue is dated January 1967. Jeff Rubens acted as Kaplan's co-editor until Kaplan's death in 1997, when Rubens became editor and publisher. Largely because of its emphasis on ...

Forcing Bid
In the card game contract bridge, a forcing bid is any that obliges the partner to bid over an intermediate opposing pass. Owing to the partnership's bidding system or a bridge convention, partner must "keep the bidding open", i.e. not pass, thereby preventing his left-hand opponent from ending the auction with a pass and enabling the "forcing bidder" to bid further. A forcing bid that creates no further obligation is called ''forcing for one round''. A bid that is ''forcing and promises a rebid'' creates an obligation on the forcing bidder next round (typically, up to some level of the auction). A ''game forcing'' bids creates a mutual obligation to continue bidding at least to game level, or to double the opponents. All bridge bidding systems use forcing bids. For instance, one over one and two over one responses to one-of-a-suit opening bids are treated as forcing in almost all bidding systems. Also, introducing a new suit at three level is generally treated as forcing prov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Relay Bid
In contract bridge, a relay bid is a conventional bid that usually has little or no descriptive meaning but asks partner to describe some feature of his hand. A relay is often the cheapest bid available but need not be. Stayman and Blackwood are common examples of relay bids. The rationale for introducing relay bids emerged from the idea that it is not always the best use of bidding space for both partners to describe their hands. Instead, only one partner can make the cheapest bids available (relays) while the other describes his hand. This is especially useful when the asker has a balanced or very strong hand. Relay bidding systems are for the most part based on relay bids: in most sequences (especially forcing ones), one partner just relays while the other describes his hand in a highly codified manner. While relay systems offer a higher level of exchanged information than natural systems, they also have the drawbacks that they are complicated to memorize and often exclude ...

Stayman Convention
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: ...

Major Suit
In the card game contract bridge, the major suits are spades () and hearts (). The major suits are of prime importance for tactics and scoring as they outrank the minor suits while bidding and also outscore them (30 per contracted trick for major suits—compared to 20 for minor suits). Much of the tactics of bidding in bridge revolves around the attempt by partners to find a "fit" in one of the major suits that will allow them to make a game contract. Another reason why the major suits is more desirable than the minor suits is that they need one less trick to make game. Of the two major suits, spades rank higher than hearts. Suit combinations Fundamentally, there are three ways to divide four suits into pairs: by ''color'', by ''rank'' and by ''shape'' resulting in six possible suit combinations. * Color is used to denote the ''red'' suits (hearts and diamonds) and the ''black'' suits (spades and clubs). * Rank is used to indicate the ''major'' (spades and hearts) versus '' mino ...
