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).

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] |
Jacoby 2NT
Jacoby 2NT (Swedish: ''Stenberg 2NT'') is a bridge convention in which a bid of 2NT over partner's opening bid of one heart (1) or one spade (1) shows a hand with both * opening strength or better - normally at least 12 HCP or a hand meeting the " Rule of 20" criteria, and * at least four-card support for opener's major suit. The 2NT response is forcing to at least game in opener's major suit. If the partnership also plays splinter bids, the Jacoby 2NT response tends to deny the shape for a splinter (i.e., no singleton or void). However, it might be the best alternative as prelude to possible slam exploration with unbalanced support in a holding stronger than the agreed range for a splinter bid. Origins In most bridge literature, the convention is said to have been developed by Oswald Jacoby. However, credit for its development has also been attributed to Leo Baron. Opener's Rebids Over a Jacoby 2NT Response With a balanced hand, opener rebids as follows: ACBLbr>"Bidding Tool ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Major Suit
In the card game contract bridge, the major suits are spades () and hearts (). The major suits are of prime importance for tactics and scoring as they outrank the minor suits while bidding and also outscore them (30 per contracted trick for major suits—compared to 20 for minor suits). Much of the tactics of bidding in bridge revolves around the attempt by partners to find a "fit" in one of the major suits that will allow them to make a game contract. Another reason why the major suits is more desirable than the minor suits is that they need one less trick to make game. Of the two major suits, spades rank higher than hearts. 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 '' mino ...

Blue Club
Blue Club is a bridge bidding system, developed mainly by Benito Garozzo. It was used by the famous Blue Team and became very popular in the 1960s. It has gained a strong following ever since. The main features are: * Strong club system: 1 opening promises 17 or more HCP, with step answers showing controls (K=1 and A=2 controls) or HCP. 1 being negative showing 0-5 HCP and 1 showing 6-12 HCP but with no more than 2 controls, 1 showing 3 controls, 1NT showing 4 controls etc. * Four-card majors: 1 and 1 and 1 openings are limited (12-16 HCP), * Canapé. With two-suited hands, the opener's second bid is in the longer suit, whereas other more popular systems bid their shorter suit second. However, unlike the "fellow" Roman Club, there are many exceptions to this rule in Blue Club. * 1NT ranging from 13 to 17 high card points. It can be either 13-15 points, which is essentially a replacement bid for a balanced club suit with two specific shapes, 3-3-3-4 and 3-3-2-5, or 16-17 pts an ...

Precision Club
Precision Club is a bidding system in the game of contract bridge. It is a strong club system developed in 1969 for C. C. Wei by Alan Truscott, and used by Taiwan teams in 1969. Their success in placing second at the 1969 Bermuda Bowl (and Wei's multimillion-dollar publicity campaign) launched the system's popularity. The central feature of the Precision system is that an opening bid of one club is used for any hand with 16 or more high card points (HCP), regardless of distribution. An opening bid of one of a major suit signifies a five-card suit and 11–15 HCP. A one notrump opening bid signifies a balanced hand (no five-card major suit) and 13–15 HCP. Popularity After the success of Taiwan teams in 1969 and 1970 Bermuda Bowls with the system, the entire Italian Blue team switched to Precision Club and won yet another World Team Olympiad in 1972. The modifications to the system were made chiefly by Benito Garozzo and he titled it Super Precision. Today, multiple world ch ...

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 ...

Strong Club System
The Strong Club System is a set of bidding conventions and agreements used in the game of contract bridge and is based upon an opening bid of 1 as being an artificial forcing bid promising a strong hand. The strong 1 opening is assigned a minimum strength promising 16 or more high card points. All other bids would therefore be limited to a maximum of 15 high card points. There are several variants of the strong club system and all are classified as artificial because the bids are highly codified. Strengths and weaknesses There are two generally acknowledged strengths of the strong club systems: # accuracy in uncontested slam-strength auctions, because the bidding starts at such a low level when opener has a fairly strong hand. # the fact that all other opening bids have their strength capped by the strong club means more accurate judgment and scope for tactical operation both in constructive and competitive bidding. The generally acknowledged weakness of such systems is the fact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Multi 2 Diamonds
Multi-coloured 2 diamonds, is a contract bridge bridge convention, convention whereby the opening bid of 2D shows a defined range of hand types. These always include a Weak two bid, 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 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 eg the Muiderberg convention, 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.

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 ...

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] |
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] |
