REOPENING DOUBLES OF 1NT RESPONSES AND REBIDS
What sort of hand should the doubler have in this auction?
South West North East
1H Pass 1S Pass
1NT Pass Pass Dbl
Many players would take this as a reopening takeout double, showing
both minor suits and a hand of this sort: S-432 H-76 D-AQ76 C-KJ75.
Played this way, such doubles are dangerous. The opponents have
not found a fit, you have no reason to believe that partner has
four cards in a minor suit (more likely he has four in each major),
and you are contracting to take 8/13 of the tricks with perhaps
6/13 of the total points.
Since the opponents figure to have a majority of the high card
points (HCP), few players would consider a double of this sort as
primarily for business. How could it be? Even with the opening lead
advantage, how can one hope to profit by doubling the stronger side
in a notrump contract?
The fallacy in this logic lies in the implied assumption that
points are the same as strength, which is not true. Point count is
an estimate of strength, an estimate that may sometimes be way off.
Points are values assigned to cards on the basis of their average
worth. That worth does not apply to every deal, however; it is just
an average. KJx counts as four points, but is almost worthless if
AQ10 is on the left. If AQ10 is on the right, the value of KJx is
greater than the point count would indicate.
This means that it is possible to double 1NT responses and rebids
in the reopening seat, and to double primarily for business. When
do you double? When the opponents seem to be overvaluing their
hands, when their high cards may not be not worth as much as they
think. How can you know for sure? You can't. You go by the odds,
as in the rest of bridge.
With length and strength (positional strength, that is: AQ10, not
AKQ) in a suit or suits bid on your right, with shortness and
weakness in any suit bid on your left, the odds become good that
the opponents have misjudged their strength and are contracting for
more tricks than they can take. Yes, they have 21-22 HCP, but with
finesses not working and suits not breaking they may end up with
only five or six tricks. They have enough points for their bid, but
not enough strength for their contract.
There are four possible situations for a reopening double of a 1NT
response or rebid, depending on how many suits have been bid:
1) South West North East
1D Pass 1NT Pass
Pass Dbl
2) South West North East
1D Pass 1S Pass
1NT Pass Pass Dbl
3) South West North East
1C Pass 1H Pass
1S Pass 1NT Pass
Pass Dbl
4) South West North East
1C Pass 1D Pass
1H Pass 1S Pass
1NT Pass Pass Dbl
What is required for each of these doubles? Let's look at each.
No. 1) is the reopening double of a 1NT response:
South West North East
1D Pass 1NT Pass
Pass Dbl
The minimum for a non-vulnerable double in this sequence might be
something like: S-A105 H-KJ3 D-K1097 C-1097.
To double with a hand this light, conditions have to be just right,
as they are here: a) The diamond suit, bid on the right, is well
bottled up; b) If partner takes out to a suit, she will find
support; c) You can stand any lead; d) You have tenaces (KJ, A10)
that may kill honor strength in opener's hand; e) You have many
honor cards, a very important factor; f) You are not vulnerable,
so down one doubled (or two undoubled) may be okay if partner runs
to a suit. If any of these conditions are weakened, you need extra
strength to compensate.
One drawback of a No. 1) double is that you have information about
only one enemy suit and cannot be confident that the opponents have
over-valued their hands. Another is that the 1NT responder has a
minimum of 6 HCP, and opener could have as many as 15 or 16.
On the other hand, the reopening double of a 1NT response is a
crunching answer to the light opening bids one sees these days,
especially in third seat. Rather than jump into the bidding with
an immediate notrump overcall or takeout double, just pass with
strength in opener's suit. If a 1NT response gets passed around to
you, the ensuing double may earn a big penalty. Sometimes the
opponents bid even higher, making your pass even more profitable.
No. 2) is the reopening double of a 1NT rebid by opener:
South West North East
1D Pass 1S Pass
1NT Pass Pass Dbl
This is the best opportunity for a lucrative double. Responder may
have only four or five HCP, stretching to show a major suit. Opener
has a maximum of 15 HCP (probably not that, if his notrump range
is 15-17 HCP). With information about two suits, you can assess the
relative strength of the two sides more accurately than in No. 1).
You might have only 10 HCP with a hand that is otherwise ideal:
S-AQ108 H-J106 D-52 C-QJ108. The conditions are perfect: strength
over the spade suit, weakness in diamonds (any finesse there will
fail), a good suit to attack after partner's probable spade lead,
and no isolated kings or queens lying under opener's high cards.
They could go down three! If partner must pull the double, you have
support for both unbid suits.
No. 3) and No. 4) are similar:
South West North East
1C Pass 1H Pass
1S Pass 1NT Pass
Pass Dbl
South West North East
1C Pass 1D Pass
1H Pass 1S Pass
1NT Pass Pass Dbl
In both sequences, each opponent has bid at least twice. Watch out
here. Responder is unlikely to be sub-minimum. A great deal is
known about the distribution of the opposing suits, but partner has
little choice about passing the double. Where can he go? Still,
with ideal holdings you can double. All it takes is a hand with
good tenace/length combinations in suits bid on the right,
weakness/shortness in those bid on the left, plus a reasonable
supply of honor cards. The doubler in No. 3) might have: S-AJ98
H-42 D-QJ10 C-A1087. The No. 4) doubler could hold: S-KJ97 H-83
D-AQ1086 C-54.
So you have doubled. Now what does partner do? Deciding whether to
pass or bid, he thinks: "Am I positionally strong in any suit bid
on my right?" "Am I weak and short in any suit bid on my left?"
"Could I score more (or lose less) by bidding instead of passing?"
If you are weak in a suit bid on your right you can rightly fear
that the opponents have a running suit there. Remember, partner is
usually weak in that suit.
Why is it good to be weak in a suit bid on the left? Partner has
implied strength there, so wouldn't it be better to have a high
card fit in that suit? No! Strength opposite strength is a wasteful
duplication. If you are not swallowing up the opponents' high
cards, you are biting the air and they may make their contract.
Always go for a likely plus in your own contract rather than
attempt a doubtful defense of 1NT doubled, especially against non-
vulnerable opponents. Buying the hand will probably be a satis-
factory result, and partner's defensive hand should reduce the
likelihood that the opponents can find a good suit contract after
your takeout bid.
Don't pull the double to a four-card suit, even with a bad hand.
If you can't beat 1NT you're probably dead anyway. Besides, the
doubler's hand is unlimited (except for a passed hand, of course).
He could have 1NT defeated in his own hand and have no support for
your suit. It is murder to double 1NT with a monster hand and then
have partner pull the double by bidding a Jxxx suit (opposite your
Qx).
After a double of 1NT, the opponents cannot play the hand un-
doubled. If either opponent runs from the double, the next hand
can pass the bid around to partner, who must bid or double. The
die was cast with the double of 1NT. If you get killed once in a
while, that's to be expected. More often you'll come out on top.
Any other policy lets the opponents off the hook too often, when
a player cannot double a runout bid and therefore chooses to bid
out of fear that partner will not act.
If you do pass the double, what do you lead? (You are on lead.)
If you lack a good suit of your own, try leading dummy's suit,
which the doubler is supposed to have covered. She may not be that
well fixed, however, so if you have some constructive lead of your
own, give it a try.
Now let's look at a hand that is not a good double, but one with
which many players would double:
West North East South
1D Pass 1S Pass
1NT Pass Pass ?
South holds, vulnerable: S-952 H-A87 D-KJ9 C-KQ64. What should he
do? The answer is pass, fast. This hand is not nearly so good as
its point count indicates. Diamonds have been bid on the left, so
KJ9 may be only as good as 432. The spade suit is breaking well,
and any finesse there will work. The ace of hearts is no surprise
to the opposition, who are quite prepared to knock out aces. If the
ace of clubs is on the left, the KQ of clubs needs the jack in
partner's hand to be worth much. If a double here is supposed to
be for takeout, good luck. North is unlikely to take more than six
tricks in a doubled contract of 2C or 2H. Here is the deal:
North
S-K43
H-9653
D-Q86
C-1093
West East
S-J107 S-AQ86
H-QJ6 H-K102
D-A10732 D-54
C-AJ C-8752
South
S-952
H-A87
D-KJ9
C-KQ64
Not so bad, at that. The diamond bidder does not have AQ over the
KJ, and the club situation is okay, although blocked. Still, they
make one or two overtricks if South doubles. Or should North pull
the double? Two hearts goes down four, even with a 3-3 trump split.
Let's change the South hand, reducing the point count but
increasing the real strength: S-KJ108 H-A1052 D-94 C-QJ10. Now
South can double 1NT with some confidence, in view of the spade
strength and diamond weakness. This time the deal is:
North
S-54
H-763
D-KJ83
C-K842
West East
S-632 S-AQ97
H-QJ4 H-K98
D-AQ762 D-105
C-A5 C-9762
South
S-KJ108
H-A1052
D-94
C-QJ10
East-West have the same sort of hands as before, with 22 HCP.
Lacking a good suit, North leads a spade against 1NT doubled. When
the smoke clears, East-West are down two, minus 300 or 500.
Get the point?
