Sacrifice (bridge)
In duplicate bridge, a sacrifice (a save in common usage) is a deliberate bid of a contract that is unlikely to make in the hope that the points will be less than the points likely to be gained by the opponents in making their contract. In rubber bridge, a sacrifice is an attempt to prevent the opponents scoring a game or rubber on the expectation that positive scores on subsequent deals will offset the negative score. Owing to the difference in the methods of scoring between duplicate and rubber bridge, a sacrifice bid in rubber bridge is much less likely to be advantageous and so strategies differ between the games. Comparable strategy differences exist between Matchpoints scoring and IMPs scoring games. Scoring context Sacrificing against game contracts In duplicate bridge scoring, if the opponents bid and make a game contract, it yields them 600 or 620 points when they are vulnerable and 400 or 420 points when they are not vulnerable, depending upon the and assuming no . ...

Duplicate Bridge
Duplicate bridge is a variation of contract bridge where the same set of bridge deals (i.e. the distribution of the 52 cards among the four hands) are played by different competitors, and scoring is based on relative performance. In this way, every hand, whether strong or weak, is played in competition with others playing identical cards, and the element of skill is heightened while that of chance is reduced. This stands in contrast to Bridge played without duplication, where each hand is freshly dealt and where scores may be more affected by chance in the short run. Four-way card holders known as Bridge boards are used to enable each player's hand to be preserved from table to table, and final scores are calculated by comparing each pair's result with others who played the same hand. In duplicate bridge, players normally play all the hands with the same partner, and compete either as a partnership (in a 'Pairs tournament') or on a team with one or more other partnerships ('Te ...

Rubber Bridge
Rubber bridge is a form of contract bridge played by two competing pairs using a particular method of scoring. A rubber is completed when one pair becomes first to win two ''games'', each ''game'' presenting a score of 100 or more contract points; a new game ensues until one pair has won two games to conclude the rubber. Owing to the availability of various additional bonus and penalty points in the scoring, it is possible, though less common, to win the rubber by amassing more total points despite losing two games out of three. Rubber bridge involves a high degree of skill but there is also a fair amount of luck involved in who gets the best cards. A popular variation of rubber bridge is known as Chicago. Playing rubber bridge Rubber bridge is played with a standard deck of 52 cards. From high to low, the cards are ranked A, K, Q, J, 10, 9, 8, 7, 6, 5, 4, 3, and 2. Suits are ranked Spades (), Hearts (), Diamonds (), Clubs (). Four players play in two partnerships, with partners ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bridge 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 ...

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 ...

Law Of Total Tricks
In contract bridge, the Law of total tricks (abbreviated here as LoTT) is a guideline used to help determine how high to bid in a competitive auction. It is not really a law (because counterexamples are easy to find) but a method of hand evaluation which describes a relationship that seems to exist somewhat regularly. Written by Jean-René Vernes for French players in the 1950s as a rule of thumb, it was first described in English in 1966 International Bridge Academy Annals. It received more notice from appearing in The Bridge World in June 1969. In 1981 Dick Payne and Joe Amsbury, using their abbreviation TNT (Total Number of Tricks), wrote at length about it for British readers. Later, in the US, Marty Bergen and Larry Cohen popularized the approach, using their preferred abbreviation: 'the LAW' (all capitals). It was prefigured in S. J. "Skid" Simon's 1945 book '' Why You Lose at Bridge'' in his aphorism "When in doubt, bid one more". Definition LoTT can be stated as f ...

Michaels Cuebid
The Michaels cuebid is a conventional bid used in the card game contract bridge. First devised by Michael Michaels of Miami Beach, FL, it is an 's cuebid in opponent's opening suit and is normally used to show a two-suited hand with at least five cards in each suit and eight or more points. After the opponents have opened at the one-level, the overcaller bids the same suit at the two-level; the two normal cases are: #Over an opponent's minor opening, a cuebid shows both majors. For example, 1 – 2 shows hearts and spades. #Over an opponent's major opening, a cuebid shows the other major and a minor suit. For example, 1 – 2 shows hearts and either clubs or diamonds. Partner can make a 2NT relay bid to request partner to bid his minor suit, or a 3 pass-or-correct bid. Partnerships who have incorporated Michaels cuebids amongst their agreements usually also play the unusual notrump convention. Requirements Point count requirements vary and are a matt ...

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.
