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 ...

Takeout Double
In the card game contract bridge, a takeout double is a low-level conventional call of "Double" over an opponent's bid as a request for partner to bid his best of the unbid suits. The most common takeout double is after an opponent's opening bid of one of a suit where the double shows a hand with opening values, support for all three unbid suits (at least three cards in each) and shortness in the suit doubled (preferably, no more than two). Normally, the partner of the doubler must bid his best suit but may pass if (a) his right hand opponent intervenes or (b) on the more rare occasions when his hand is such that he wishes to convert the takeout double to a . Requirements Commonly a double is considered for takeout whenever one of the following conditions is met (but see balancing double below): *Opponents have previously bid only one suit, and the player did not have chance to double that suit before. *Opponents have previously bid two suits, and partner has passed. *Opponents ...

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] |
Overcall
In contract bridge, an overcall is a bid made after an opening bid has been made by an opponent; the term refers only to the first such bid. A ''direct'' overcall is such a bid made by the player seated immediately to the left of the opener, i.e. next in the bidding rotation; an overcall in the 'last seat', i.e. by the player to the right of opener, which is made after two intervening passes, is referred to as a '' balancing'' or ''protective'' overcall. Objectives The overcaller has one or more of the following objectives: *To secure the contract *To suggest a good lead from partner *To induce the opponents to a higher-level contract *To find an effective sacrifice *To hinder the opponents in their bidding Suit overcalls In most bidding systems, an overcall in an unbid suit is natural, denoting length and strength in the suit bid. The common requirements include: * A good five-card or any longer suit; the features that qualify a suit as 'good' are subject to partnership agreem ...

Playing For Penalties
Play is a range of Motivation#Incentive theories: intrinsic and extrinsic motivation, intrinsically motivated activities done for recreational pleasure and enjoyment. Play is commonly associated with children and juvenile-level activities, but may be engaged in at any life stage, and among other higher-functioning animals as well, most notably mammals and birds. Many prominent researchers in the field of psychology, including Melanie Klein, Jean Piaget, William James, Sigmund Freud, Carl Jung and Lev Vygotsky have erroneously viewed play as confined to the human species, believing play was important for human development and using different research methods to prove their theories. Play is often interpreted as frivolous; yet the player can be intently focused on their objective, particularly when play is structured and goal-oriented, as in a game. Accordingly, play can range from relaxed, free-spirited and spontaneous through frivolous to planned or even compulsive. Play is not ...

Rubber Bridge
Rubber bridge is a form of contract bridge played by two competing pairs using a particular method of scoring. A rubber is completed when one pair becomes first to win two ''games'', each ''game'' presenting a score of 100 or more contract points; a new game ensues until one pair has won two games to conclude the rubber. Owing to the availability of various additional bonus and penalty points in the scoring, it is possible, though less common, to win the rubber by amassing more total points despite losing two games out of three. Rubber bridge involves a high degree of skill but there is also a fair amount of luck involved in who gets the best cards. A popular variation of rubber bridge is known as Chicago. Playing rubber bridge Rubber bridge is played with a standard deck of 52 cards. From high to low, the cards are ranked A, K, Q, J, 10, 9, 8, 7, 6, 5, 4, 3, and 2. Suits are ranked Spades (), Hearts (), Diamonds (), Clubs (). Four players play in two partnerships, with partners ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alvin Roth (bridge)
Alvin Leon Roth (November 6, 1914 – April 18, 2007) was an American bridge player, considered one of the greatest of all time, and "the premier bidding theorist of his bridge generation". He wrote several books on the game, and invented various bidding conventions that have become commonplace, including five-card majors, negative doubles, forcing notrump, and the unusual notrump.(Obituary) ''''. May 26, 2007. Roth was considered a fascinating theorist but was described by one partner, Richard "Dick" Freeman, as "very tough to sit opposite—unless you were so thick-skinned that ...

Sputnik
Sputnik 1 (; see § Etymology) was the first artificial Earth satellite. It was launched into an elliptical low Earth orbit by the Soviet Union on 4 October 1957 as part of the Soviet space program. It sent a radio signal back to Earth for three weeks before its three silver-zinc batteries ran out, and continued in orbit for three months until aerodynamic drag caused it to fall back into the atmosphere on 4 January 1958. It was a polished metal sphere in diameter with four external radio antennas to broadcast radio pulses. Its radio signal was easily detectable by amateur radio operators, and the 65° orbital inclination made its flight path cover virtually the entire inhabited Earth. The satellite's unanticipated success precipitated the American Sputnik crisis and triggered the Space Race, part of the Cold War. The launch was the beginning of a new era of political, military, technological and scientific developments. The word ''sputnik'' is Russian for ''satellite'' when ...

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] |
Negative Free Bid
Negative free bid is a contract bridge treatment whereby a free bid by responder over an opponent's overcall shows a long suit in a weak hand and is not forcing. This is in contrast with standard treatment, where a free bid can show unlimited values and is unconditionally forcing. The treatment is a relatively recent invention, and has become quite popular, especially in expert circles. Negative free bids resolve relatively frequent situations where the responder holds a long suit with which he would like to compete for a partscore, but is deprived from bidding it by opponent's overcall. Example For example, if South holds: , partner opens 1 and East overcalls 1, he couldn't bid 2 in standard methods, as it would show 10+ high-card points, and a negative double would be too off-shape. With NFB treatment in effect though, he can bid 2 which the partner may pass (unless he has extra values and support, or an excellent suit of its own without tolerance for hearts). However, ...

Bridge World Standard
Bridge World Standard (BWS) is a bidding system in the card game contract bridge, first developed and serially published in 1967-69 as BWS 1968 by The Bridge World magazine. Like the Standard American Yellow Card (SAYC), it was intended "for use by impromptu or casual partnerships" and "as a basis for discussion by those who wish to formulate their own system." The system was updated as the BWS 1984, BWS 1994, BWS 2001 and BWS 2017 editions. It is based on majority preferences of polled experts and readers of the magazine. The system shares some similarities with 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 'Go ... and 2/1 game forcing, but with many advanced treatments.
