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] |
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] |
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] |
Bridge Convention
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 ...

Contract Bridge Glossary
These terms are used in contract bridge, using duplicate or rubber scoring. Some of them are also used in whist, bid whist, the obsolete game auction bridge, and other trick-taking games.

Forcing Pass
In the card game bridge, a forcing pass is an agreement or understanding that a pass call obliges the partner to bid, double, or redouble over an intermediate opposing pass, i.e. partner must "keep the bidding open". : ... – (act) – Pass – (Pass) – ? Here "..." represents any beginning to the auction. The forcing pass (bold) necessarily occurs directly over an opposing bid, double, or redouble (act). After a pass over a pass, the auction might end before partner's turn. In other words, the partnership is committed to act ''somehow'' rather than to end the auction now; that is a precondition. The first, direct, "forcing pass" refers to partner the choice ''how'' to act. There is no commitment to accept partner's choice. Indeed, a forcing pass ensures that the auction will return to the one who issues it, so it may be interpreted as the first half of a two-step action by that player. Normally double is natural where pass is forcing. That is, double suggests ... [...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.

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 ...

Reverse (bridge)
A reverse, in the card game contract bridge, is a bidding sequence designed to show additional strength without the need to make a jump bid; specifically two suits are bid in the reverse order to that expected by the basic bidding system. Precise methods and definitions vary with country, bidding system and partnership agreements. Definitions Standard American In Standard American a reverse is defined by William S. Root as "... a non-jump bid at the two-level in a new suit ''that ranks higher than the suit you bid first''", and by Bridge World. as "a non-jump bid in a new suit that bypasses a bid in a lower-ranking suit already bid by the same player". Acol The Acol definition is somewhat wider and includes ''any bid of a new suit by opener higher than two of their first suit''. Application ;Example In the auction, 1 – 1; 2, the 2 rebid by opener meets the foregoing definitions and is a reverse showing a stronger than minimum opening hand and forcing responder to bid for one mo ...
