Blackout Convention
Blackout is a bridge convention for responding to a reverse bid after a one-over-one beginning, whereby the responder can show whether or not he has better than a minimum response. Responder makes the cheapest bid from either the fourth suit or 2NT to show a hand that has no game interest. All other bids show reasonable hands, generally in the eight point range and are game-forcing. The objective of Blackout is to allow the constructive game-going hands to keep the bidding level low and give more room for the strong auctions that may lead to slams. The convention is also known as ''Wolff Over Reverses''. Responder then rebids as follows: * A rebid of his own suit shows five or more cards in the suit and is for one round, but does not promise any extra strength. * The cheapest bid of the fourth suit is forcing and 2NT shows exactly four cards in his own suit and a minimum hand for his . * The non-cheapest bid of the fourth suit is forcing and 2NT shows exactly four cards in his o ...

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.

Reverse (bridge)
A reverse, in the card game contract bridge, is a bidding sequence designed to show additional strength without the need to make a jump bid; specifically two suits are bid in the reverse order to that expected by the basic bidding system. Precise methods and definitions vary with country, bidding system and partnership agreements. Definitions Standard American In Standard American a reverse is defined by William S. Root as "... a non-jump bid at the two-level in a new suit ''that ranks higher than the suit you bid first''", and by Bridge World. as "a non-jump bid in a new suit that bypasses a bid in a lower-ranking suit already bid by the same player". Acol The Acol definition is somewhat wider and includes ''any bid of a new suit by opener higher than two of their first suit''. Application ;Example In the auction, 1 – 1; 2, the 2 rebid by opener meets the foregoing definitions and is a reverse showing a stronger than minimum opening hand and forcing responder to bid for one mo ...

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] |
Suit (cards)
In playing cards, a suit is one of the categories into which the cards of a deck are divided. Most often, each card bears one of several pips (symbols) showing to which suit it belongs; the suit may alternatively or additionally be indicated by the color printed on the card. The rank for each card is determined by the number of pips on it, except on face cards. Ranking indicates which cards within a suit are better, higher or more valuable than others, whereas there is no order between the suits unless defined in the rules of a specific card game. In a single deck, there is exactly one card of any given rank in any given suit. A deck may include special cards that belong to no suit, often called jokers. History Modern Western playing cards are generally divided into two or three general suit-systems. The older Latin suits are subdivided into the Italian and Spanish suit-systems. The younger Germanic suits are subdivided into the German and Swiss suit-systems. The French suits a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lebensohl
Lebensohl is a contract bridge convention whose variants can be used in the following situations: * by responder after an opponent's overcall of a one notrump (1NT) opening bid in order to compete further in the auction without necessarily committing the partnership to game. * after opponents' weak-two bids and * in responding to a reverse by partner. Origins and spelling The origins of the convention are unknown and various views about its spelling have ensued. The Official Encyclopedia of Bridge (OEB) first listed LEBENSOHL in its third edition published in 1976 and attributed its design to George Boehm; the fourth OEB edition, under the entry LEBENSOLD, states that George Boehm first described the convention and that Boehm had wrongly attributed it to Ken Lebensold; the fifth and sixth editions state likewise but under LEBENSOHL. In the seventh edition and for the first time, the OEB notes "Uniquely amongst bridge conventions, it should arguably be spelled with a lowercase firs ...
