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.

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 ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Namyats
In the card game bridge, Namyats is a conventional agreement to open hands with a long major suit that are too strong for a direct preemptive opening with a 'two-under' transfer bid. When the long suit is in hearts, opener bids 4, and when in spades, opener bids 4. Accordingly, the method was originally named 'Four Club and Four Diamond Opening Transfers'; it is also referred to as 'Mitchell Transfers', after the developer of this bidding method, Victor Mitchell. The name 'Namyats' is the surname of Mitchell's bridge partner, Samuel Stayman, spelled backwards. In England, this convention is known as 'South African Texas', a name borrowed from a similar variant on the Texas transfer Texas transfer, or simply Texas, is a bidding convention in contract bridge designed to get the partnership to game in a major suit opposite a one notrump or two notrump opening, thus making the opener declarer and keeping the stronger hand hidden f ... convention played over 1NT opening bids.

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 ...

Acol
Acol is the bridge bidding system that, according to ''The Official Encyclopedia of Bridge'', is "standard in British tournament play and widely used in other parts of the world". It is a natural system using four-card majors and, most commonly, a weak no trump. Origins Acol is named after the Acol Bridge Club in London NW6, where it originated in the early 1930s. The club was founded on Acol Road, named after Acol, Kent. According to Terence Reese, the system's main devisers were Maurice Harrison-Gray, Jack Marx and S. J. "Skid" Simon. Marx himself, writing in the ''Contract Bridge Journal'' in December, 1952, said: "...the Acol system was pieced together by Skid Simon and myself the best part of 20 years ago." In another account, Marx and Simon... The first book on the system was written by Ben Cohen and Terence Reese. Skid Simon explained the principles that lay behind the system, and the system was further popularised in Britain by Iain Macleod. The Acol system is contin ...

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 mat ...

Ogust Convention
Ogust is a bridge convention used by responder after his partner has made a weak-two opening bid; its purpose is to gauge the strength of the weak-two bidder's hand. Named after Harold A. Ogust from the United States, the convention is also known as the 'Blue Club response' from the bidding system developed by Benito Garozzo Benito Garozzo (born 5 September 1927) is an Italian American bridge player. He won 13 world championship titles with the Italian Blue Team, starting in 1961 when he was added as a last minute substitute for the Bermuda Bowl, playing in regular .... Application After a weak-two opening bid, a forcing relay bid of 2NT by responder asks opener to describe the strength and quality of his hand. Responder usually has values worthy of an opening bid and is interested in game, although he does not guarantee trump support. Responses The standard responses to the Ogust convention are: * 3 shows a "minimal" hand with a "poor" suit * 3 shows a "minimal" hand wit ...

Strong Two Clubs
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 b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
