We open 2♦ Flannery 11 to a bad 16 HCP at least 5 hearts and 4 spades
Basic structure of responses and rebids
Responder’s bids are
pass how to play 2 diamonds:
2♥ or 2♠ to play not invitational; may have only 2 hearts
3♥ or 3♠ slam invitational at least game forcing; sets trump
subsequent new suits are cuebids 4N by either KC (or BW)
3♣ to play; opener can raise clubs only
3♦ natural and invitational in diamonds only; could pass 2♦ if weak
2NT asks opener for further information and is either invitational
(usually) or better in a major or slammish in a minor
then opener bids as follows:
3♣ SHO in clubs 4531 or 4540 (very unusual) then
3♥ is invitational to 4♥
3♠ is invitational to 4♠
4♥ or 4♠ are to play, not slammish
4♦ sets diamonds as trumps and asks for KC for diamonds
remember that opener has diamonds
3N is to play
4♣ is natural and invitational, but not forcing
3♦ SHO in diamonds 4513 or 4504 (very unusual) then
3♥ is invitational to 4♥
3♠ is invitational to 4♠
4♥ or 4♠ are to play, not slammish
4♣ sets clubs as trumps and asks for KC for clubs
remember that opener has clubs
3N is to play
4♦ is natural and invitational but not forcing
3♥ 4522 minimum then
pass; way to play 3♥ when opener has a minimum
3♠ sign off in 3 spades since opener has a minimum
4 of either minor is invitational
3♠ 4 spades and 6 hearts
responder sets contract
3N 4522 maximum
responder sets contract but 4 of either minor is game forcing
4♣
transfer to 4♥ how to play from
opener’s side
then 4N by responder after the transfer is KC
4♦
transfer to 4♠ how to play from opener’s side
then 4N by
responder after the transfer is KC
4♥
or 4♠ to play no slam interest; how to play from responder’s
side
We open Flannery and they double
system on and pass means we want to play 2 diamonds
We open Flannery and they bid a suit
system off
double penalty
all bids by responder are non forcing except cuebids
Suggested defense to Flannery
They open 2 ♦ Flannery
Double general takeout with 14+
2♥ both minors typically the values for at least a minimum opening bid
2♠ natural and typically the values for a 2 level overcall
2N strong NT usually about 15 to 18 may have good minor
no Stayman or transfers 3 clubs and 3 diamonds are weak
3♣ natural sound overcall
3♦ natural sound overcall
3♥ asks partner to bid 3N with a heart stopper usually has a solid minor
3♠ intermediate jump overcall in spades, good suit, invitational to game
3N to play
4 clubs or 4 diamond very long suit, invitational to game
4♥ both minors; huge hands, game forcing, slammish
Rationale for and advantages of playing Flannery
1. In one bid it preempts the opponents and limits and accurately describes opener’s hand as to his strength and distribution
2. If you play forcing NT over your major openings and opener holds 4522, opener has to rebid a 2 card minor and suppress what may be a strong 4 card suit even when opener is 4531.
3. When playing Flannery, when the opening bid is 1 heart, responder knows that opener does not have spades unless he has 16+ HCP. This is valuable knowledge that he possesses that the opponent’s are not likely to be aware of unless they understand Flannery and are astute enough to have noticed that the partnership is playing it.
4. After a heart opening and a 2 over 1
by responder, a 2 spade rebid by
opener shows 16+ HCP. If not playing Flannery, 2 spades just shows
values in spades and
says nothing about strength.
5. When playing Flannery, responder doesn’t have to respond 1 spade with 4 weak spades, so a 1 spade response tends to show 5, and opener can freely raise with 3 card support.
6. Flannery is very destructive to the opponent’s bidding as usually only expert pairs have good tools to defend against it
7. Weak 2 bids in diamonds are descriptive, but opener’s side is usually outranked and outbid, so good opponents will declare almost double dummy. A 3 diamond opening is likely to be much more effective. How badly to you miss playing weak 2 bids in clubs?
8. Although it is a descriptive bid, the
Flannery opener usually becomes
dummy, and declarer’s hand is completely unknown. For example,
2 diamonds by opener, then
4 hearts or 4 spades by responder.
9. Playing IMPS, Flannery is a tool with
the potential for an inferior team
to be in a position to pick up a big
swing if the right Flannery hand comes
up when the better team is
not playing it. There is sometimes nothing
they can do about it.
10. I hate to play against it.
An example of a partnership that plays Flannery is Paul Soloway and Bob Hamman .
