Шаблон:For Шаблон:Main Flannery is a bridge convention using a 2Шаблон:Diams opening bid to show a hand of minimal opening bid strength (11-15 high card points) with exactly four spades and five (or sometimes six) hearts. It was invented by American player William (Bill) L. Flannery.

This convention was introduced because of the awkwardness of describing such a holding, especially with four-card major systems. For example, with the hand Шаблон:BridgeHandInline, if the bidding starts 1Шаблон:Hearts - 1NT (denying four spades), the opener cannot rebid 2Шаблон:Spades, as it would be a reverse bid showing a stronger hand, 2Шаблон:Hearts would show a six-card suit, and two of a minor would show four or at least three good cards. Thus, the opener cannot easily explore for a 5-3 fit in hearts. Five-card major openers are somewhat better placed, because 1NT denies both three hearts and four spades, so opener may pass more safely but is nevertheless at risk of missing a potential optimum 4-3 Шаблон:Gcb fit in spades. Flannery is also useful when playing five-card majors in conjunctions with forcing notrump, to prevent opener from having to respond in a nonsuit after 1Шаблон:Hearts – 1NT when not strong enough to reverse.

Responses

Responder's only forcing bid is 2NT; all other bids are natural. The responses are:

Anti-Flannery

"Anti-Flannery" is a variation used in systems which use the canapé treatment, where a shorter suit is opened first. It is used in some variations of Blue Club and Lancia systems. With canapé in effect, hands with 4=5 in majors are naturally opened 1Шаблон:Spades with 2Шаблон:Hearts rebid, however, hands with five spades and four hearts present a problem and the 2Шаблон:Diams artificial bid can be used to show that holding. Continuations are similar to basic Flannery.
