An opening Flannery 2D bid shows 11-15 HCP with exactly four spades and five hearts. The purpose of Flannery is to avoid rebid problems with this hand type; a 1 opening sometimes leads to trouble when opener cannot bid 2S (a reverse) at his next turn.

The responses to the Flannery 2D opening are:

Pass 6+ diamonds, signoff
2 Natural, signoff
2 Natural, signoff
2NT Artificial and forcing, asking opener to further describe his hand (see below)
3 6+ (7+) clubs, signoff
3 6+ (7+) diamonds, invitational
3 3+ hearts, 10-12 points, invitational
3 4+ spades, 10-12 points, invitational
3NTNatural, signoff
4 Transfer to 4
4 Transfer to 4
4 4+ hearts, signoff
4 4+ spades, signoff


After the artificial 2NT response, opener's rebids clarify his minor-suit distribution. This helps responder decide whether his own minor-suit values are suitable for game or slam. Opener's conventional rebids are:

3 4-5-1-3 shape
3 4-5-3-1 shape
3 4-5-2-2 shape, minimum
3 4-5-2-2 shape, maximum
3NT 4-5-2-2 shape, both minor suits stopped
4 4-5-0-4 shape
4 4-5-4-0 shape


In competition, the specialized Flannery responses and rebids are on. Any double of an opposing overcall does not indicate a 'stolen bid' but is for penalties.


Origins
