Asking Bid
In contract bridge, an asking bid is a convention used to seek a slam accurately. There are two types - colour asking bids and notrump asking bids. Constructed by bridge pioneer Ely Culbertson in the 1940s, they have been superseded by other methods; however, one remaining commonly used asking bid is the 5NT Grand slam force. The application of Asking bids requires making distinctions between the ''asking colour'', ''the agreed trump'' and the two remaining ''side colours''. Replies by partner are in accordance with a schedule of defined meanings. What is an Asking bid? First there has to be an agreed trump colour. The trump agreement can be done explicit as well as implicit. Thereafter ''the first'' asking bid has to be either a double jump in a new colour not bid by the partner or the one who puts the asking bid forward, or (without a jump) at the fourth level. After an asking bid, the one who has put the first asking bid forward, will be like the Captain of a ship, and his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Bridge Conventions
A bridge convention is an agreement about an artificial or a set of related artificial calls. Calls made during the auction phase of a contract bridge game convey information about the player's card holdings. Calls may be "natural" (that is, are based on a holding of the suit bid, or a balanced distribution in the case of a notrump bid) or "" (show a feature unrelated to the named denomination). Purpose Contract bridge is a trick-taking card game played by four players in two competing partnerships in which a sequence of , also known as the auction, precedes the play of the cards. The purpose of this bidding is for players to inform their partners of the content of their hand and to arrive at a suitable contract at which to play the hand (or to prevent the opponents from arriving at a suitable contract). Although bidding is often "natural" (describing a hand by simple reference to possession, shape, and strength of the named suit), players may also bid using conventions, which as ...

Slam-seeking Conventions
Slam-seeking conventions are codified artificial bids used in the card game contract bridge. Bidding and making a small slam (12 tricks) or grand slam (13 tricks) yields high bonuses ranging from 500 to 1500 points. However, the risk is also high as failure to fulfill the slam contract also means failure to score the bonus points for a game (300-500). Conventions have been devised to maximise the opportunity for success whilst minimising the risk of failure. Contract bridge bidding systems are mainly "natural" (most bids have an obvious meaning) or "artificial" (many bids have a meaning unrelated to the denomination mentioned). However, even natural systems such as Acol find occasional need to resort to artificial means called conventions. A very common type of conventional bid is of the slam-seeking variety to be used in situations when a small slam or a grand slam appears possible but more information is needed before the optimum contract can be determined. In order to make ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ely Culbertson
Elie Almon Culbertson (July 22, 1891 – December 27, 1955), known as Ely Culbertson, was an American contract bridge entrepreneur and personality dominant during the 1930s. He played a major role in the popularization of the new game and was widely regarded as "the man who made contract bridge". He was a great showman who became rich, was highly extravagant, and lost and gained fortunes several times over. Life Culbertson was born in Poiana Vărbilău in Romania to an American mining engineer, Almon Culbertson, and his Russian wife, Xenya Rogoznaya. He attended the École des sciences économiques et politiques at the Sorbonne in Paris, and the University of Geneva. His facility for languages was extraordinary: he spoke Russian, English, French, German, Czech and Spanish fluently, with a reading knowledge of five others, and a knowledge of Latin and classical Greek. In spite of his education, his erudition was largely self-acquired: he was a born autodidact. After the Russian Re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grand Slam Force
The Grand Slam Force is a bidding convention in contract bridge that was developed by Ely Culbertson in 1936. It is intended to be used in cases where the combined hands of a partnership are so strong that a slam (winning at least 12 tricks) is a near-certainty and a grand slam (winning all 13 tricks) is a possibility. It enables a player to gain information about the quality of the top trumps held by his partner (i.e., which of the ace, king or queen). When the Grand Slam Force was invented in the 1930s (when it was called "Josephine," named after Ely's then-wife Josephine Culbertson), Blackwood had not evolved into what has become the standard: Roman Keycard Blackwood (often called RKCB). Using KCB, there are 5 keycards -- the four aces and the king of trumps. The responses to 4NT are: 5C = 1 or 4 keycards; 5D = 0 or 3 keycards; 5H = 2 keycards without the Queen of trumps; 5S = 2 keycards with the Queen of trumps. As you can see, there is no need to bid 5NT to ask for the A, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trump (card Games)
A trump is a playing card A playing card is a piece of specially prepared card stock, heavy paper, thin cardboard, plastic-coated paper, cotton-paper blend, or thin plastic that is marked with distinguishing motifs. Often the front (face) and back of each card has a fi ... which is elevated above its usual rank in trick-taking games. Typically, an entire Suit (cards), suit is nominated as a ''trump suit''; these cards then outrank all cards of plain (non-trump) suits. In other contexts, the terms ''trump card'' or ''to trump'' refers to any sort of action, authority, or policy which automatically prevails over all others. Etymology The English word '':wikt:trump, trump'' derives from ''Trionfi (cards), trionfi'', a type of 15th-century Italian playing cards, from the Latin '':wikt:triumphus, triumphus'' "triumph, victory procession", ultimately (via Etruscan) from Greek Thriambus, θρίαμβος, the term for a hymn to Dionysus sung in processions in his honour.

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 books b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 '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.

Cue Bid
In contract bridge, a cue bid (also, cuebid or cue-bid) is either a bid of the opponents' suit, or "slam seeking": a slam-investigating bid made during an auction's later rounds that shows control of a suit. Traditionally a cue bid is "slam seeking", but in the early 21st century the usage appears to be giving way to ''control bid''. Bid of the opponents' suit After the opponents have bid a suit, a cue bid of that suit is normally intended as a forcing bid. It shows interest in contesting the contract and asks partner to describe their hand. Immediate cue bid An immediate cue bid is made directly over opponent's opening bid. Traditionally, it denotes a hand unsuited for a takeout double. For example, after RHO opens 1, a hand such as would prefer not to double for takeout, because partner might make a penalty pass. A cue bid of 2, as traditionally used, would be appropriate: it tends to show great high card strength, probably with a hand pattern unsuited to defense. Partner is ...

Culbertson 4-5 Notrump
The Culbertson 4-5 notrump is a slam-seeking convention in the game of contract bridge. It was devised in the early 1930s by Ely Culbertson. Most four-notrump conventions (Blackwood and its variants being the best known) demand that bidder's partner define their hand using agreed codified responses. In contrast, the Culbertson 4-5 describes the bidder's hand, and invites partner to use their judgement in the light of that information. Description A bid of four notrump (subject to common-sense defined exceptions) shows either: * Any three aces, or * Two aces, and the king of any suit previously bid by either partner. In response: * A bid of five notrump shows either: ** Any two aces, or ** One ace, and the kings of all suits previously bid by either partner. * A bid of a new suit shows first-round control (ace or void) there, but is not compulsory with such a holding. * Six of a previously-bid suit shows a desire to play there (holding one ace, or the kings of all bid suits). * Fiv ...
