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. Variations Requirements for a weak two bid vary by partnership. A common agreement is that it requires: * a ''good'' suit of exactly 6 cards in diamonds, hearts or spades; longer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Strong Two Bid
In contract bridge, a strong two-bid (also known as a forcing two-bidFrancis et al (2001), p. 443.Francis et al (2001), p. 163. The strong two-bid was the cornerstone of the Culbertson system.) is an opening bid of two in a suit, i.e. 2, 2, 2 or 2 . It is a natural bid, used to show a hand that is too strong to open at the one level. Commonly used in the early days of bridge, most expert players converted after World War II to the now more common weak two bid retaining only 2 as a strong opening suit-bid and changing its meaning to artificial and forcing holding any suit. This was done on the basis that the weak two-bid would occur much more frequently. In Standard American bidding, Charles Goren advocated that a strong two-bid should indicate a five-card suit with 25 high card points (HCP), a six-card suit with 23 HCP, or a seven-card suit with 21 HCP and is to game. In Acol, the main bidding system in the United Kingdom, strong two bids are still used by many players. The 2, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antispades Twos
Antispades Twos (also known as Antispades Weak Twos) is the name of a bidding convention in the card game bridge. It is a two-level pre-emptive opening based on either a 6-card suit or a two-suiter with at least nine cards distributed across any two suits. * The 2 opening promises 5-10 HCP and either a 6-card club suit, or clubs and diamonds, or clubs and spades. * The 2 opening promises 5-10 HCP and either a 6-card diamond suit, or diamonds and hearts, or diamonds and spades. * The 2 opening promises 5-10 HCP and either a 6-card heart suit, or hearts and spades, or hearts and clubs. * The 2 opening is artificial and very strong, promising either 23+ HCP balanced, or a hand of 16+ HCP and four losers or better. A drawback is that there is no way to make a standard weak two opening in spades with a 6 card suit. Responder also does not know whether opener is one- or two-suited and whether it is safe to look for a better fit. Responses The partner of the Antispades Weak Two opener ...

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.

Multi 2 Diamonds
Multi-coloured 2 diamonds, is a contract bridge convention whereby the opening bid of 2D shows a defined range of hand types. These always include a weak-two bid in a major suit, and the second option, that must be a strong. The inherent ambiguity as to both suit and strength makes a powerful, and hence popular. It was originally considered disruptive, but is now thought fairly easy to defend. It is commonplace in the British Isles, permitted in international competition, but rarely seen in North America. The convention offers several constructive system opportunities. You might choose that its weak option always be a standard 6-card Major, and then use 2H and 2S as e.g. the Muiderberg/Lucas Two two-suited weak openings. The strong options are also important as they may be used "garage” hand types that are otherwise awkward within your general system. Some English pairs include 2NT with 5-card major or 6-card minor.

Muiderberg Convention
Muiderberg is a bidding convention in the card game bridge. It is a two-level preemptive opening based on a two-suiter with precisely a five-card major and a minor suit (four-card or longer). In Muiderberg the 2 opening denotes five hearts and an unknown minor suit, whilst 2 denotes five spades and an unknown minor suit. The convention is also known as the Dutch Two, Lucas Two or Woo Two (mainly UK) opening. __NOTOC__ The convention is named after the Dutch village Muiderberg, the residence of the designers of the convention – Onno Janssens and Willem Boegem. Responses The partner of the Muiderberg opener can take the following actions: * pass (with tolerance for the opened suit) * bid 3 (a pass-or-correct bid) * bid 3 to invite for game in the major suit * bid 2 (over 2) as a contract improvement (opener is allowed to raise with a suitable hand) * bid 3/ (opener's suit) as a preemptive raise * bid 3/ (other major) which is non-forcing but invitational * ask for the minor suit us ...

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. 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 with a "good" suit * 3 shows a "maximal" hand with a "poor" suit * 3 shows a "maximal" hand with a "good" suit * 3NT shows a "solid" suit (that is, AKQ of the long suit) The definitions of "minimal" and "maximal" hands and "poor" and "good" suits are matt ...

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 convention card. 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.

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 bid diffe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Convention (bridge)
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 ...

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''.
