SPLINTER RESPONSES TO A MINOR
A preemptive double jump in a major suit, opposite a minor suit
opening, does not come up very often:
Opener Responder
1C/1D 3H/3S
Can we find a better use for this response? How about using it
for those unbalanced game-going hands with a five-card major and
four or five-card support for opener's minor? When partner opens
1D and you have S-3 H-AJ842 D-A8763 C-K6, the bidding is sure to
go:
South West North East
1D Pass 1H 1S
Pass 4S 5D
If South has S-J2 H-K5 D-KQ954 C-A873, a slam is missed. If he has
S-KJ H-107 D-Q9542 C-AQJ2, the right contract is 4S doubled. With
three-card minor suit openings so common these days, the problem
is even worse when responder has only four-card support.
Even if the opponents don't compete, responder's hand is hard to
describe. He can, however, do so in one bid if a 3H or 3S response
is played as a splinter bid. It goes like this:
A double jump response in a major suit, opposite a minor opening,
is a splinter bid, showing:
-- Game-going hand, strength in three suits
-- Singleton in the splinter suit
-- Doubleton or tripleton in the unbid minor
-- Five cards in the unbid major
-- Four or more cards in opener's minor
Opener Responder
1C 3H
Responder has S-AJ1073 H-4 D-A3 C-QJ863. If responder were to bid
1S instead, and next hand preempts with, say, 4H, this hand may not
get described. The 3H splinter bid tells the whole story in one
call, before the opponents can interfere, and tells it more
accurately than any other sequence. It also has great preemptive
value.
A passed hand cannot make this special splinter bid. All such jumps
by a passed hand are normal preemptive bids.
Double jumps in a minor suit are not splinter bids:
Opener Responder
1C 3D - normal preemptive bid
This might be useful to show a 4-4-1-4 hand, or a forcing-to-game
club raise (popular in England), but this chapter deals only with
major suit splinters.
Opener Responder
1D 4C - normal preemptive bid
The complete text of SPLINTER RESPONSES TO A MINOR comprises three
single-spaced pages. It adds to the above the effects of opposing
bids on the convention: Does it apply when the opening is over-
called or doubled? Suppose there is a jump overcall?
SPLINTER RESPONSES TO A MINOR was published in The Bridge World,
