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] |
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] |
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 ...

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 ...

Vanderbilt Club
Vanderbilt Club was one of the earliest bidding systems in the game of contract bridge. It was devised by Harold S. Vanderbilt, who had in 1925 devised the game itself. It was published by him in 1929. It was the first strong club system. An updated version was published in 1964. As of 2017, it has long been obsolete. Overview In the Vanderbilt Club system, an opening bid of 1 is artificial and forcing, and shows a good hand. A response of 1 is an artificial negative. Other bids are "regulation bids". The system was published by Harold S. Vanderbilt in his 1929 book ''Contract Bridge''. It was the first strong club system. An updated version was published in 1964. Vanderbilt was a very early bridge theorist, because in his 1929 book he explained in detail the reasoning upon which his system was based: "In many Contract hands it is essential that an original bidder be assured of a second opportunity to bid". 1929 system The Official Encyclopedia of Bridge has called Vanderb ...

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] |
EHAA
EHAA (''Every Hand An Adventure'') is a highly natural bidding system in contract bridge characterized by four-card majors, sound opening bids, undisciplined weak two-bids in all four suits and a mini notrump, usually of 10–12 high card points. Weak two-bids An EHAA two-bid shows six to twelve high card points, and a five card or longer suit. There are no restrictions on suit quality (xxxxx and AKQJxxxx both qualify). EHAA bidders use a "get in quick, get out quick" style, which permits interference or an opening bid in nearly every auction, protected by fairly strict requirements on further bids by the partnership. EHAA two-bids are made in ''all four suits''; there is no forcing opening bid in EHAA. Responses to the EHAA two bid fall into three categories. All jump bids are forcing to game and slam invitational, because any hand which could force to game opposite a minimum EHAA two-bid must be interested in slam opposite a maximum. (However, a direct jump to game is a two- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fantunes
In the game of contract bridge Fantunes is a natural bidding system initially developed Carlos Mosca and popularized by Fulvio Fantoni and Claudio Nunes - two players that were later found to be cheating and were banned from play by many bridge federations The Fantunes system differs in approach from other bidding systems used by world class bridge players. Opening bids of one and two of a suit are stronger than in most systems, with one level suit openings natural and forcing one round, and constructive two-level openings. The one notrump opening denotes a balanced or semi-balanced hand with 12-14 HCP which can include a singleton or a five-card major suit. Opening one of a suit is natural but forcing, unlimited in strength that contains at least 14 high-card points (HCP). An exception is made for opening 1 or 1 with as little as 11 HCP when holding five cards in the bid suit and four cards in the other major. For an example of such a "light" opening bid, holding , second seat wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boring Club
The Boring Club (or in Dutch: Saaie klaver) is a bidding system in the card game contract bridge, designed by Lucas Smid of the Netherlands. In this system all balanced ('boring') hands, that in most natural systems would be opened 1NT or would be opened in a suit at one level with the plan to rebid 1NT or 2NT, must be opened with 1. The general idea behind this system is to get the information about the shape of the hand (balanced or unbalanced) across to partner in the first bid. The opening bids in boring club can be summarised as follows: *1: Balanced (12-18 hcp), no five card major *1: 4+, unbalanced (10-21 hcp) *1: 5+ (10-21 hcp) *1: 5+ (10-21 hcp) *1NT: 5+ (10+ hcp) *2: Balanced (19-22 hcp), may contain five card major *2: Multi (including 23+ NT and game forcing hands) *2: Muiderberg convention *2: Muiderberg convention *2NT: Two suiter in both minors with longer clubs (10-15 hcp) The 1 opening A boring club 1 opening shows 12-18 high card points in a balanced hand not co ...

Romex System
The Romex system is a contract bridge bidding system designed by the Mexican bridge expert George Rosenkranz. Key features of Romex are the multiple meanings attributed to certain bids, namely the dynamic one notrump and the Mexican two diamonds. Dynamic one notrump The dynamic one notrump opening indicates either: *a balanced or unbalanced hands in the range of 19-21 high card points (HCP) and six controls, or *an unbalanced hand just short of a 2 opening. The most common responses to the dynamic one notrump opening are: *2 – negative (0-5 HCP) *2 – 6+ HCP, game force. Higher-level responses indicate control count. A consequence of the use of the dynamic notrump is that the 1NT rebid by opener becomes wide-range (typically 12-16 hcp). With game invitational values or better, responder reacts to such a rebid with a 2 convention to ask opener to further describe his hand. Mexican two diamonds This opening indicates one of four hands: *a balanced hand with 21-22 p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kaplan–Sheinwold
The Kaplan–Sheinwold (or "K-S") bidding system was developed and popularized by Edgar Kaplan and Alfred Sheinwold during their partnership, which flourished during the 1950s and 1960s. K-S is one of many natural systems. The system was definitively described in their 1958 book ''How to Play Winning Bridge'' and later revised and retitled to ''The Kaplan-Sheinwold System of Winning Bridge'' in 1963. Kaplan–Sheinwold and the Roth-Stone system were the two most influential challengers to Standard American bidding in the US in the 1950s, 1960s, and 1970s. Although K-S is not frequently played in its original form in the 21st century, many of its features (though not the 12–14 point 1NT opening) survive in the popular 2/1 Game Forcing system. Additionally, a few elements of Kaplan–Sheinwold (notably Five-Card Majors) have become accepted as part of Standard American practice. Among modern experts, Chip Martel and Lew Stansby play a system closely modeled on K-S, with load ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
