Flannery
Flannery to bridge bidding convention by William Flannery. In the basic version of this convention, openly 2♦ shows five hearts and exactly four peaks in the strength of a weak opening, roughly 11-15PH (and therefore below the strength needed for the reverse). The main assumption Flannery is to avoid difficult rebid problems in sequence 1♥ – 1BA (if 1NT is played for forcing. An additional advantage of this convention is the quick sale of the opening hand, allowing you to quickly find fits (or misfits) and blocking enemies (although Flannery is by design a constructive convention). The main disadvantage is the relatively low frequency, with which hands suitable for opening appear Flannery. Some versions of this convention use opening 2♥ instead 2♦. There are many versions of the response schemas, the basic version looks like this:
Belt A weak hand with penalties 2♥/♠ For the game, fit at least two in hearts or three in spades 2BA Strong and forcing to the tip 3m Natural, non-forcing but constructive, partner should bid 3N with a Hx fit or better 3S Invitating with fit 3NT To play 4 ♣ Transfer to 4♥ 4♦ Transfer on 4♠ 4S Do gry
