New Minor Forcing
New Minor Forcing (NMF), is a contract bridge bidding convention used to find a 5-3 or 4-4 major suit fit after a specific sequence of bids in which opener has rebid one notrump. The convention is triggered by responder at his second turn by an artificial bid of two in an unbid minor; it requires that he hold five cards in the major he has previously bid and an unlimited hand ranging in value from at least game invitational strength (11 or more points) to that sufficient to have interest in slam; he may also hold four cards in the other major. Accordingly, there are six bidding sequences in which the New Minor Forcing bid may be applied: Auction notes:1. The opponents are silent throughout.2. The ! indicates that the bid is . The New Minor Forcing bid by responder is forcing for one round and asks partner for further information on his shape and strength with the primary objectives of determining if opener has three-card support for responder's five-card major and/or if the ...

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. During the auction, partners use their bids to also exchange information about their hands, including o ...

Bidding 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 "Contract bridge glossary#natural, 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 Contract bridge glossary#play, 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 ...

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 ...

Checkback Stayman
Stayman is a bidding convention in the card game contract bridge. It is used by a partnership to find a 4-4 or 5-3 trump fit in a suit after making a one (1NT) opening bid and it has been adapted for use after a 2NT opening, a 1NT overcall, and many other natural notrump bids. The convention is named for Sam Stayman, who wrote the first published description in 1945,"A New Notrump Convention", Samuel Stayman, ''The Bridge World'', June 1945. but its inventors were two other players: the Great Britain, British expert Jack Marx (bridge), Jack Marx in 1939, who published it only in 1946, and Stayman's regular partner George Rapée in 1944. *3 = --> *3 = ? *3NT = to play After a transfer, accept it with any 4333, bid 3NT with only two trumps, otherwise bid 4M. 1NT - 2; 2/2NT - 3 = Stayman *3 = 4M333 *3 = 4, not 4333 *3 = 4, not 4333, not 4 *3NT = no 4M 1NT - 2; 2/2NT - 3, 3 *3 = 4, not 4 *3 = 4, not 4 *3NT = to play *4 = bid your 4 card Major An alternative, simpl ...

Transfer Walsh
Transfer Walsh is a bidding convention used in contract bridge. After a 1 opening bid, responses of 1 and 1 show heart and spade suits respectively. The "Walsh" terminology refers to the fact that these bids may conceal an equal or longer diamond suit. It allows opener to play a greater proportion of major-suit and no-trump contracts, particularly when using five-card majors. Using Transfer Walsh Transfer Walsh is used responding to partner's 1 opening bid. The main responses are as follows: * 1: Shows at least four hearts * 1: Shows at least four spades * 1: Shows at least four, alternatively five diamonds * 1NT: Shows 6-9 HCP and a balanced hand without a four-card major A variation is to have 1 show either diamonds or 6-9 HCP balanced, with the 1NT response showing 10-11 HCP balanced. The term ''Transfer Walsh'' is commonly used, although responder's one level bids are not forcing a completed transfer from opener. In fact, over the 1 and 1 responses, opener will only accept ...

Walsh Convention
:''See the Glossary of contract bridge terms for an explanation of unfamiliar words or phrases.'' Walsh is a convention used in the card game of bridge in response to an opening bid of 1. The convention has its origins in the Walsh System developed by Richard Walsh. In general, the Walsh convention is not used in four-card major systems such as Acol, but may be employed in some five-card major systems; especially those that use a prepared club, rather than better minor. The opening bid of 1 will therefore have shown either clubs or a balanced hand. When responder is too weak to force to game diamond suits are bypassed in favour of major suits, regardless of the length of the diamond suit. For example, holding , the response to the opening bid of 1 would be 1 rather than the normal 1. Continuations vary according to other details of the system being played. If Checkback Stayman is being played, then the auction 1 – 1; 1NT – 2 would show this hand and end the auction. I ...

XY Notrump Convention
XY Notrump (also known as Two Way Checkback and Two Way New-Minor-Forcing) is a bidding convention in contract bridge. Using the convention After opener's one of a suit (X), partner's one of a suit response (Y) and opener's 1NT rebid (a very common sequence), 2 from opener's partner forces 2 from opener. Holding a weak hand with diamonds, one can now pass. Other bids are invitational, describing also the nature of the hand. A 2 response to 1NT, however, is game forcing with any hand. Responder may also jump to 3 of any suit (except 3, which is signoff) to show a slam-invitational hand with good suit(s). Examples For example, on the sequence 1-1 (with or without opponent's interfering);1NT-2;2,2 will show an invitational hand with minimum five spades and four hearts, 2 an invitational hand with minimum five spades (in which case one does not have four hearts) or possibly six spades with or without four hearts. 2NT will show a balanced invitational hand, 3 typically an unbalance ...

XYZ Convention
XYZ is a bidding convention in contract bridge. Using the convention After opener's one of a suit (X), partner's one of a suit response (Y) and opener's 1-level rebid (Z) (a very common sequence), 2 from opener's partner forces 2 from opener. Holding a weak hand with diamonds, one can now pass. Other bids are invitational, describing also the nature of the hand. A 2 rebid by responder, however, is game forcing with any hand. Responder may also jump to 3 of any suit (except 3, which is signoff) to show a game-forcing hand with a good suit or, if the jump is in one of opener's suits, two of the top three honors. Although it is mandatory in the XY Notrump form of the convention to complete the relay 2 to 2, when Z was a suit, opener may be unlimited. In such a case it is acceptable, if opener has too good a hand to risk being dropped in 2 to bypass the relay and make a (forcing) bid. It is also customary to retain the convention in the face of certain competitive actions, for exam ...
