BIDDING OVER A DOUBLE
North East South
1S Dbl 2S Very weak raise, may have passed 1S.
1S Dbl 3S/4S Preemptive, weak, distributional. South is
bidding as high as he dares, with few HCP.
1H/1S Dbl 2NT Artificial raise of opener's major, four-card
support or better, a hand too strong for any
raise (all raises are preemptive), not good
enough for a redouble. Probably 10-11 HCP,
counting distribution, usually including a
singleton. Avoid the 2NT bid with a balanced
hand--you may go down when the opponents have
nothing their way. The Stoplight convention
(chapter STOPLIGHT in the book "Marvin's
Conventions and Treatments) does not apply
in this situation.
1H/1S Dbl 3NT Normal strong artificial raise
1H/1S Dbl 4C/4D Splinter bid, strong, ignoring the double
1S Dbl 4H Same
1H Dbl 3S Same
1C Dbl 1S Not forcing. Not a weak four-card suit. May
be a weak hand, but does not deny redoubling
strength. With a major suit and support for
partner's suit, it pays to bid the major
rather than redouble--even with as much as
11 HCP. When you have two important features
to show in a hand, a redouble may get in the
way. Of course you must redouble with a game-
going hand.
1S Dbl 2C Not forcing, but not a worthless hand. A
minimum: S-64 H-J76 D-43 C-KQ10986
1D Dbl 1NT 6-9 HCP, almost as if the double had not
occurred. May have a weak four-card major.
A minimum is dangerous against good opposi-
tion, who may double.
1D Dbl 2NT Same as a limit raise, but a maximum of
9 HCP. Redouble with more.
1D Dbl 3NT Natural bid: S-K3 H-K2 D-A108765 C-J87
1C Dbl 3NT
1C Dbl 2D/2H/ Not quite forcing, showing a strong six-
2S card suit and a fairly good hand, like a weak
two bid.
1S Dbl 3C/3D/ is the same, but the suit could be seven
3H long. A minor suit jump invites 3NT,
requiring a suit headed by AQJ or better.
Preemptive by a passed hand.
1C Dbl 3D Preemptive, not a forcing club raise
1C/1D Dbl 3H/3S Preemptive response, not a splinter bid
South East North West
1S Dbl Rdbl P
P 2C 2S A 10-12 point raise, probably three trumps
1S Dbl Rdbl P
P 2C 3S Good limit raise, four or more trumps, too
much in high cards for a 2NT response over
the double, not enough for a game bid
1C Dbl Rdbl P
P 2C 2H Forcing, in view of the redouble
1H Dbl Rdbl P
2C 2NT Forcing. With 11-12 HCP, pass (forcing)
and bid 2NT on the next round (not forcing).
1H Dbl Rdbl 2C
P P 2NT Not forcing, because the auction would be
over if the redoubler passes.
1C Dbl 1S P
2S P 3C Not forcing, in view of the failure to
redouble. Not weak, could have 11 points.
Does not indicate a psychic spade bid.
Probably 4-4 in the two suits.
A redouble nominally shows about 11 HCP or more, sometimes 10 with
good support for partner's suit. A pass, however, does not deny a
good hand. It is sometimes wise to pass with a good 4-4-4-1 hand
that is short in opener's suit, rather than redouble. The redouble
may keep the opponents from bidding higher than they should, a
common fault of takeout doublers.
With two suits to show, it may be better to start naming the suits
rather than redouble. When RHO doubles 1C, bid 1S with S-K10842 H-3
D-AQJ65 C-42. If 1S gets passed out, you probably aren't missing
a game.
There are some medium strength hands that do not lend themselves
well to any action over a double. With such hands it is better to
pass and act later. Partner opens 1S, next hand doubles, you have:
1) S-3 H-K987 D-Q1087 C-A974
2) S-J73 H-A9642 D-K843 C-6
3) S-Q1064 H-A83 D-K62 C-942
Hand 1) is not good enough for a redouble, even if you like to
redouble with this shape. Pass and double whatever the opponents
bid.
Hand 2) is too good for a 2S raise, but the trumps are not good
enough for the artificial 2NT raise. Pass and hope to bid later.
Hand 3) is also too good for a 2S raise, but the 2NT bid is unwise
with a balanced hand. Eight tricks may be the limit in spades, and
the opponents may have nothing their way. Pass and raise on the
next round.
When you pass over a double, then bid or double later, partner will
assume you have a fair hand like one of the above. Be careful not
to pass with a weaker hand and then act later.
When a takeout double has been redoubled, the doubling side cannot
play the hand unless they play it doubled. A pass by either partner
over an opposing bid is therefore a forcing pass.
When a takeout double is made on opener's right (over responder),
opener should redouble with 17 HCP regardless of his holding in
partner's suit. A jump rebid therefore tends to be based more on
distribution than on high cards.
