Carrot 4NT
The Carrot 4NT slam-convention was developed in Carrot Club, but can be used in any bidding system instead of the more common Blackwood or RKC conventions. It is a refinement of an older convention, Culbertson 4NT. Rather than asking for Aces or keycards, 4NT is used to ''show'' number of keycards. This convention applies when 4NT is preceded by cuebid 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 seeki ...s, and generally when 4NT is a non-jumping bid. The immediate advantage of this approach over Blackwood/RKC, is that while still establishing the combined number of keycards, the pair will be able to use the 5-level for cuebids, too, to more thoroughly explore and negotiate their slam-potential. Normally, 4NT shows at least 3 out of 5 keycards (including the King of trumps) plus f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carrot Club
Carrot Club (or ''Morotsklöver'' in Swedish) is a strong club system, developed in the 1970s and played in international teams championships by Danielle Nughes, Anders Morath and Sven-Olov Flodquist. They won the European teams championships in 1977 and placed third in the World teams championships in 1977 and 1991. Some features of the system are a natural 4+card 1 opening, canapé-openings with longer -suit, Carrot 1NT (a "wide" 1NT-opening showing 13–17 hcp; if 13–14, may not have a 4-card major), and the Carrot 4NT slam convention.

4NT (bid)
Slam-seeking conventions are codified artificial bids used in the card game contract bridge. Bidding and making a small slam (12 tricks) or grand slam (13 tricks) yields high bonuses ranging from 500 to 1500 points. However, the risk is also high as failure to fulfill the slam contract also means failure to score the bonus points for a game (300-500). Conventions have been devised to maximise the opportunity for success whilst minimising the risk of failure. Contract bridge bidding systems are mainly "natural" (most bids have an obvious meaning) or "artificial" (many bids have a meaning unrelated to the denomination mentioned). However, even natural systems such as Acol find occasional need to resort to artificial means called conventions. A very common type of conventional bid is of the slam-seeking variety to be used in situations when a small slam or a grand slam appears possible but more information is needed before the optimum contract can be determined. In order to make a sm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cuebid
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 ...

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] |
