Rosenkranz Double
The Rosenkranz double and Rosenkranz redouble are elements of a bridge bidding convention invented by Dr. George Rosenkranz, collectively known as the Rosenkranz double. It is a made by the (partner of the ) in an auction where opener, overcaller and responder have all bid different suits. It is used to describe the advancer's top honor card holdings in the overcaller's suit. Original version The conventions come into play when the auction has started with: (a) an opening bid by the opponents; (b) a direct overcall by partner at the one-level; and (c) a bid or negative double (that is, not a Pass) by the opener's partner, responder. Two cases follow: (1) if responder bids below two of opener's suit, Double by advancer is a raise of the overcall and promises a top honor; (2) if responder doubles, Redouble by advancer has the same meaning. Either way, advancer's natural raise to the two-level denies possession of a top honor in that suit. A top honor is either the Ace, King or Que ...

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 ...

Negative Double
The negative double is a form of takeout double in bridge. It is made by the responder after their right-hand opponent overcalls on the first round of bidding, and is used to show shortness in overcall's suit, support for the unbid suits with emphasis on majors, as well as some values. It is treated as forcing, but not unconditionally so. In practice, the negative double is sometimes used as a sort of catch-all, made when no other call properly describes responder's hand. Therefore, a partnership might even treat the negative double as a wide-ranging call that merely shows some values. Usage Using the modern negative double convention, it is understood that a double over an initial overcall is conventional, and ''not'' for penalties (but see Playing for penalties). For example, using this convention, the following doubles would be regarded as negative, not for penalty: *1 – (1) – Dbl *1m – (1M) – Dbl *1 – (1) – Dbl *1M – (2m) – Dbl In understandings regarding nega ...

Rosencrantz And Guildenstern
Rosencrantz and Guildenstern are characters in William Shakespeare's tragedy ''Hamlet''. They are childhood friends of Hamlet, summoned by King Claudius to distract the prince from his apparent madness and if possible to ascertain the cause of it. The characters were revived in W. S. Gilbert's satire, ''Rosencrantz and Guildenstern'', and as the alienated heroes of Tom Stoppard's absurdist play, ''Rosencrantz and Guildenstern Are Dead'', which was adapted into a film. ''Rosencrantz'' ("rose wreath") and '' Gyldenstjerne/Gyllenstierna'' ("golden star") were names of Danish (and Norwegian, and Swedish) noble families of the 16th century; records of the Danish royal coronation of 1596 show that one tenth of the aristocrats participating bore one or the other name. James Voelkel suggests that the characters were named after Frederik Rosenkrantz and Knud Gyldenstierne, cousins of Tycho Brahe who had visited England in 1592.

Snapdragon Double
The snapdragon double (also known as competitive double, fourth-suit double, or impossible double) is a bidding convention in contract bridge. It is a call of double by fourth hand, when three different suits have been bid by the first three players and shows a good holding in the fourth suit (generally six cards, though some partnerships allow five) and tolerance for partner's suit. The word snapdragon derives from ''Antirrhinum ''Antirrhinum'' is a genus of plants commonly known as dragon flowers, snapdragons and dog flower because of the flowers' fancied resemblance to the face of a dragon that opens and closes its mouth when laterally squeezed. They are native to r ...'', which is a genus of plants commonly known as snapdragons from the flowers' fancied resemblance to the face of a dragon that opens and closes its mouth when laterally squeezed, which as a result produces a snap-like sound.
