Gambling 3NT
In the card game contract bridge, Gambling 3NT is a special of an opening of 3NT. The bid is used to describe a hand containing a minor suit of at least seven cards in length and headed by the ace, king and queen, at minimum. The bid has the dual objectives of preempting the opponents' bidding should they hold the and trying for a game in notrump on the gamble that partner might hold adequate support. Because this conventional bid replaces the standard use of opening 3NT (a hand with 25-27 high card points and a balanced distribution), partnerships must use other bids to show the standard 3NT hand. For partnerships which also employ the use of the strong two club convention, that bid can be used to describe a standard 3NT opening hand. For example, the following bidding sequence: replaces the traditional 3NT opening bid if gambling 3NT and strong two club is in use. That is, North's hand is best described as 25 to 27 high card points and a balanced distribution. Respons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Card Game
A card game is any game using playing cards as the primary device with which the game is played, be they traditional or game-specific. Countless card games exist, including families of related games (such as poker). A small number of card games played with traditional decks have formally standardized rules with international tournaments being held, but most are folk games whose rules vary by region, culture, and person. Traditional card games are played with a ''deck'' or ''pack'' of playing cards which are identical in size and shape. Each card has two sides, the ''face'' and the ''back''. Normally the backs of the cards are indistinguishable. The faces of the cards may all be unique, or there can be duplicates. The composition of a deck is known to each player. In some cases several decks are shuffled together to form a single ''pack'' or ''shoe''. Modern card games usually have bespoke decks, often with a vast amount of cards, and can include number or action cards. This ...

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] |
Minor Suit
In contract bridge the minor suits are diamonds () and clubs (). They are given that name because contracts made in those suits score less (20 per contracted trick) than contracts made in the major suits (30 per contracted trick), and they rank lower in bidding. In particular, one can make game with a four-level bid in a major suit, while a five-level bid is required in a minor. Of the two minor suits, diamonds rank higher than clubs. 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 ''minor'' (diamonds and clubs) suits. * Shape is used to denote the ''pointed'' (diamonds and spades, which visually have a sharp point uppermost) versus ''rounded'' (hearts and clubs) suits. This is used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. The level to w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High Card Points
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), the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strong Two Club
Bridge bidding systems that incorporate a strong 2 clubs opening bid include modern Standard American, standard Acol, 2/1 game forcing and many others. In most natural bridge bidding systems, the opening bid of 2 is used exclusively for hands too strong for an opening bid at the one-level. Typically, the bid is reserved for hands that are almost strong enough to bid to the game level on their own power, or even stronger. The exact requirements for the bid vary considerably depending upon the system used and partnership agreement. In most early bidding systems, opening bids of two of a suit signified a very strong hand and were referred to as strong two bids. However, pioneer bridge inventors like Pierre Albarran and David Burnstine saw that the frequency of such bids is fairly low, and that a 2 bid can be used for all strong hands, leaving other two-level opening bids for other purposes (for example, weak two bids). Bid requirements The strength requirements for the 2 bid ... [...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 us ...
