Drury Convention
The Drury convention is a bridge convention, used to show a game-invitational major suit raise by a passed hand while guarding against a light opening by partner in third or fourth seat. It is initiated by an artificial and forcing 2 response by the passed hand to a 1 or 1 opening by partner. The 2 bid shows at least three-card support for opener's suit with 10-12 support points and asks opener to clarify the strength of their opening hand. The convention is also known in Europe as "Toronto". Origins and purpose The convention was developed by Canadian Douglas Drury (1914–1967) and his then playing partner Eric Murray (1928–2018) to manage Murray's propensity to open light in third seat. Opening light (i.e. with marginally less than normal values) in the third seat is a common and effective bidding tactic because the player in the fourth seat may well have the best hand at the table and be poised to open the bidding given the opportunity. A third seat light opening, especia ... [...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] |
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 ...

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 ...

Hand Evaluation
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] |
Eric Murray (bridge)
Eric R. Murray (31 August 1928 in Hamilton, Ontario – 19 May 2018) was a Canadian contract bridge player and co-founder of the Canadian Bridge Federation (CBF). He and his long-time regular partner Sami Kehela were considered two of the best Canadian players in the history of the game. The Eric R. Murray Trophy, named in his honour, is awarded to the open team representing Canada in the quadrennial World Team Olympiad (continued after 2004 as part of the World Mind Sports Games). Murray was one of "four young bridge experts led by Robert F. Jordan" who won the annual Vanderbilt Cup in 1961, when it was contested in a 64- double-elimination tournament. Murray was already a Toronto lawyer; his bridge partner Charles Coon was manager of the Boston Chess Club. The same quartet tied for second in the Reisinger later that year and Coon–Murray went on to qualify for the 6-man North America team in the 1962 Bermuda Bowl, in which they finished second to Italy's Blue Team.

Matchpoint Scoring
While a deal of bridge is always played following a unique set of rules, its scoring may vary depending on the type of event the deal is played on. There are two main categories of scoring: rubber and duplicate. Rubber scoring, and its popular variant Chicago, are mostly used in social play. Duplicate scoring is focused on tournament competition and has many variations that compare and rank the relative performance of partnerships and teams playing the same deals as their competitors. Terminology The following terms and concepts, defined in the glossary of contract bridge terms, are essential to understanding bridge scoring: * * * * * or Made * * * and grand slam * *Undoubled, and *, and Scoring elements Bridge scoring consists of nine elements. Not all elements are included in all game variants and the method of accumulation of the elements over several deals varies. * If the contract is made, the score for each such deal consists of: ** Contract points, assigned to ea ...

Game Try
A game try (also called a game trial bid) in the card game of bridge is a bid that shows interest in bidding a game and asks partner to help in making the decision. For example, (using Acol or Standard American bidding) if opener, with around 16-17 HCP, bids 1 and partner responds 2 (showing 6 – 9 support points) opener is in a quandary: if responder has a maximum strength hand, with well-positioned high cards, then game will probably make; but the information revealed so far is not accurate enough for either partner to decide whether to play in game or only part score. Originally, opener would make a game try by bidding 3 (inviting game) and responder would then bid game with maximum (8-9) points or pass with minimum (6-7) points. Modern game try bids permit more accurate decision-making. Following a simple raise by partner (e.g. 1 – 2), opener bids a new suit either to show extra values or to ask responder to show more about his values. There are a variety of methods to do ...

Forcing Notrump
The forcing notrump is a bidding convention in the card game of bridge. In Standard American bidding, the response of 1NT to an opening bid of 1 or 1 shows 6 to 9 high card points (HCP) and is ''non-forcing''. Opener, with a balanced minimum, may pass the 1NT response and, if the opponents also pass, that will become the contract. A partnership may agree that this bid is ''forcing'' for one round; if the intervening opponent passes, opener must bid at least once more. This guarantees the responder at least one more opportunity to bid or pass. This mechanism allows the partnership to use the 1NT response for a greater variety of hands: in particular, ''invitational'' as well as ''minimum'' responder holdings. The forcing notrump is used over major suits only; 1NT is always standard and non-forcing over the minor suit In contract bridge the minor suits are diamonds () and clubs (). They are given that name because contracts made in those suits score less (20 per contracted trick) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strong Notrump After Passing (SNAP)
Strong notrump after passing (SNAP) is a bridge bidding convention originated by Jeremy Flint and Tony Priday and is a one notrump (1NT) bid by a passed hand in response to a one-level opening by his partner. Similar to the Drury convention, SNAP is intended to keep the contract at a low level when it is possible that partner has opened with a light or minimum hand in third or fourth seat. While a 1NT response would typically show 6-9 (or 6-10) high card points (HCP) in most Standard American partnership agreements, the SNAP 1NT response instead shows a relatively balanced hand with 9-12 (or 10-12) HCP and no five-card major that could have been bid at the one-level. When using SNAP, a 2NT response shows a balanced limit jump raise in opener's suit. Limitations Responding hands containing 6-8 points are problematic, especially if partner opens in spades. Some 6 point hands are passed and some 8 point hands are bid at the two-level. SNAP gives an adva ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
