Pass-or-correct Bid
In the card game bridge a pass-or-correct bid (or convertible bid), is a non-forcing bid that asks partner to pass or bid differently based on her/his holding. Pass-or-correct bids are generally used as responses to multiway bids. A typical example is the 2 response on a multi 2 diamonds opening that asks partner to pass with a weak hand with long spades, or to bid three hearts with a weak hand and long hearts. This 2 bid implies length in hearts and denies length in spades. Pass-or-correct bids that are made in a suit you ''don't'' hold when length in one of two suits has been shown by partner's bid, are also referred to as ''paradox responses''.

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 ... [...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] |
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.

CRASH Convention
In the game of contract bridge, CRASH (an acronym for Color-RAnk-SHape) is a defense against a strong 1 or a 1NT opening that first appeared in 1976 in an article by Kit Woolsey in The Bridge World. Within the CRASH framework, intervening calls after the 1NT opening denote either (a) two-suited hands of the same color (black or red), the same rank (major or minor), or the same shape (pointed or rounded) or (b) a natural one-suited hand (hearts or spades). Over a 1NT opening, the following CRASH overcall structure applies: Following the two-suited overcalls, advancer will bid taking into account that out of the two possible two-suited hands of intervenor, the likely holding is in advancer's shortest suits. The responses are therefore convertible. For instance, following a CRASH double, an advancer holding will start from the assumption that intervenor holds length in the black suits in which advancer's maximum length is three cards, rather than in the red suits in which his maxim ...

Suction Convention
Suction is a contract bridge bidding convention used to intervene over an opponent's 1NT opening. Using the suction convention, a suit overcall of a 1NT opening is conventional and denies the suit actually bid. It shows either: # a one-suiter in the next higher ranking suit or # a two suiter in the other two suits. The overcall bids are summarized as follows: If responder passes, advancer is required to bid the next higher ranking suit. If overcaller has the one-suited hand, he passes. Otherwise, he bids yet the next higher suit, showing that suit plus the remaining, unbid suit. Advancer then takes a preference by passing or bidding the remaining suit. Optionally additional overcalls are available to show the two non-touching suit pairs in the foregoing table – namely clubs with hearts and diamonds with spades. The first pair are referred to as the 'rounded' suits and the other as the 'pointed' suits owing to the shape of the tops of their pips. A call of 'Double' would sh ...

Mini-Roman 2 Diamond
Mini-Roman or Mini-Roman 2 Diamonds is contract bridge convention whereby the opening bid of 2 shows a three suited hand and 11-15 high card points (HCP). The convention is meant to help responder to judge, more quickly, the right level of the contract and the best trump suit (or if notrump would be better). History The Roman Club system, developed in the 1950s, included a treatment of these three suited hands with 2 showing a weaker hand and 2 a stronger hand. A response by partner of 2NT was forcing to game. The Blue Club system of bidding was developed and became widely popular in the 1960s and included a 2 bid to show a 4-4-4-1 hand with 17-24 HCP Description An opening bid of 2 shows one of two distributions: 4-4-4-1 or 5-4-4-0 (the five card suit is usually not a major suit) and 11-15 HCP The Mini-Roman 2 opening is a forcing bid. Responder has the following options. * 2: Pass or correct and non-forcing; * 2: Pass or correct to 3 and non-forcing; * 2NT: Forcing, asking o ...

Antispades Twos
Antispades Twos (also known as Antispades Weak Twos) is the name of a bidding convention in the card game bridge. It is a two-level pre-emptive opening based on either a 6-card suit or a two-suiter with at least nine cards distributed across any two suits. * The 2 opening promises 5-10 HCP and either a 6-card club suit, or clubs and diamonds, or clubs and spades. * The 2 opening promises 5-10 HCP and either a 6-card diamond suit, or diamonds and hearts, or diamonds and spades. * The 2 opening promises 5-10 HCP and either a 6-card heart suit, or hearts and spades, or hearts and clubs. * The 2 opening is artificial and very strong, promising either 23+ HCP balanced, or a hand of 16+ HCP and four losers or better. A drawback is that there is no way to make a standard weak two opening in spades with a 6 card suit. Responder also does not know whether opener is one- or two-suited and whether it is safe to look for a better fit. Responses The partner of the Antispades Weak Two opener ...
