Ekren Convention
In the game of bridge, Ekren refers to a preemptive opening of 2 defined as 4-4, 4-5, 5-4 or 5-5 in the major suit, majors and 3-10 Hand evaluation, high card points. This conventional preempt was designed by Bjørn Olav Ekren from Norway and is an example of the modern style of highly aggressive preemptive bidding. Responses Responses to a 2 Ekren opening: :Pass = to play (can be a tactical manoeuvre in the absence of a major suit fit and does not guarantee long diamonds) :2/ = to play :2NT = relay (invitational or stronger) :3 = natural, not forcing :3 = invitational with 3-3 in the majors :3/ = preemptive, to play :4/ = to play In responding to the 2NT relay the opener indicates whether he holds a minimum or a maximum (because of their playing strength 5-5's are generally considered maximum), and - in case of a maximum - the distribution in the majors: :3 = any minimum (responder's 3/ rebid now indicates an invite) :3 = 5-5 min or max (creates Forcing bid, game force) :3 = 4-5 ...

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.

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] |

Forcing Bid
In the card game contract bridge, a forcing bid is any that obliges the partner to bid over an intermediate opposing pass. Owing to the partnership's bidding system or a bridge convention, partner must "keep the bidding open", i.e. not pass, thereby preventing his left-hand opponent from ending the auction with a pass and enabling the "forcing bidder" to bid further. A forcing bid that creates no further obligation is called ''forcing for one round''. A bid that is ''forcing and promises a rebid'' creates an obligation on the forcing bidder next round (typically, up to some level of the auction). A ''game forcing'' bids creates a mutual obligation to continue bidding at least to game level, or to double the opponents. All bridge bidding systems use forcing bids. For instance, one over one and two over one responses to one-of-a-suit opening bids are treated as forcing in almost all bidding systems. Also, introducing a new suit at three level is generally treated as forcing prov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Low Countries
The term Low Countries, also known as the Low Lands ( nl, de Lage Landen, french: les Pays-Bas, lb, déi Niddereg Lännereien) and historically called the Netherlands ( nl, de Nederlanden), Flanders, or Belgica, is a coastal lowland region in Northwestern Europe forming the lower basin of the Rhine–Meuse–Scheldt delta and consisting of three countries: Belgium, the Netherlands and Luxembourg. Geographically and historically, the area also includes parts of France and Germany such as the French Flanders and the German regions of East Frisia and Cleves. During the Middle Ages, the Low Countries were divided into numerous semi-independent principalities. Historically, the regions without access to the sea linked themselves politically and economically to those with access to form various unions of ports and hinterland, stretching inland as far as parts of the German Rhineland. Because of this, nowadays not only physically low-altitude areas, but also some hilly or elevated regi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multi 2 Diamonds
Multi-coloured 2 diamonds, is a contract bridge bridge convention, convention whereby the opening bid of 2D shows a defined range of hand types. These always include a Weak two bid, weak-two bid in a major suit, and the second option, that must be a strong. The inherent ambiguity as to both suit and strength makes a powerful, and hence popular. It was originally considered disruptive, but is now thought fairly easy to defend. It is commonplace in the British Isles, permitted in international competition, but rarely seen North America. The convention offers several constructive system opportunities. You might choose that its weak option always be a standard 6-card Major, and then use 2H and 2S as eg the Muiderberg convention, Muiderberg/Lucas Two two-suited weak openings. The strong options are also important as they may be used "garage” hand types that are otherwise awkward within your general system. Some English pairs include 2NT with 5-card major or 6-card minor.

Muiderberg Convention
Muiderberg is a bidding convention in the card game bridge. It is a two-level preemptive opening based on a two-suiter with precisely a five-card major and a minor suit (four-card or longer). In Muiderberg the 2 opening denotes five hearts and an unknown minor suit, whilst 2 denotes five spades and an unknown minor suit. The convention is also known as the Dutch Two, Lucas Two or Woo Two (mainly UK) opening. __NOTOC__ The convention is named after the Dutch village Muiderberg, the residence of the designers of the convention – Onno Janssens and Willem Boegem. Responses The partner of the Muiderberg opener can take the following actions: * pass (with tolerance for the opened suit) * bid 3 (a pass-or-correct bid) * bid 3 to invite for game in the major suit * bid 2 (over 2) as a contract improvement (opener is allowed to raise with a suitable hand) * bid 3/ (opener's suit) as a preemptive raise * bid 3/ (other major) which is non-forcing but invitational * ask for the minor suit usi ...
