BRIDGE TALKS
BY MRS. JOHN MUNCE, yR.

This talk is on the business double.
The second general type of double is the
business double and it is made for the
added penalty 1t infiicts on the losing
declarer
In business double you say to your
partner, Il feel sure we can defeat this
bid, and I want to make 100 for each
extra trick we can take instead Of so.
and do not want you to take me out
unless you think the double will not be
profitable and that We are certain to
go game in your declaration" This
business double can seldom be used in
the early stages of bidding.
Any double of one, two or three bid
Of suit, after your partner has bid
or doubled, is business.
The double of q one no trump, IL
partner has bid or doubled, is business,
and the double of q two no trump bid,
regardless Of whether partner has bid
or not, is always considered business, as
well as the double of four or flve bid
of any suit.
The double Of q bid, which If made
would give the bidders game whether or
not 1t be doubled, such as double Cat
love score) of three no trump, four
hearts or five diamonds, or the double
If two hearts or two diamonds, when the
adversaries have Is on their trick score,
ured out that the odds are almost two to
one against a free double.
A doubtful double should never be
made when your partner may have
game hand. If your partner has been
doubled for business and you have a
strong hand, 1t will help him win. For
example, dealer holds:
spades-lKinE and queen.
Diamonds-Ace, king, jack, s-spot. 6-spot
Clubs@s-spot. s-spot, s-spot. 4-spot and
2-spot
Dealer bids one diamond initially,
second hand bids one spade, third hand
two hearts, fourth hand three spades.
Dealer passes, second hand passes and
third hand dealers partner), bids four
hearts. and fourth hand doubles. It is
possible. but hardly probable, that five
diamonds could be made, but partner
has bid four hearts without assistance
other than your initial diamond bid.
Therefore, as this hand contains three
quick tricks, with sound bidder for
partner it Is better not to take your
partner out.
If your hand is weak and you take
him out, the chances are you will make
matters worse. For example, dealer
bids one no trump, second hand two
hearts, third hand passes, fourth hand
Two SpdQSS, Q6dlCf bIiCIl DlQS LIlIee Ulds
monds and second hand doubles. Third
hand, dealers partner, holds the fol-
lowing:
Spades-None.
Hearts-8-spot. 6-spot, 4-spot and 2-spot.
Diamonds--o-spot, 7-spOt and 3-spot.
Clubs-Jack, 10-spot, 6-spot, 4-spot and 4
spot.
With this holding, it would be unwise
to take your partner out of business
double, as this hand will probably help
your partner by the ability to ruff
spades. You must realize it Is seldom
sound bidding to take your partner out
Of business double, particularly II he
is sound bidder himself.
Unless player really learns the rules
Of doubling, he cannot play as advan-
tageously as the player who knows when
and how to use them. A halfway un-
derstanding of them is often very dis
astrous.
When doubling for information or
business, always remember these simple
rules:
Be sure you know what you wish to
tell your partner. Also, that you will
by your bid, double or pass. Convey the
right messages to him.
Be sure your partner understands the
rules Of doubling. so you may under
stand any message he may send you by
his bid or you send him.
Be sure that you and your partner
know the difference between informa-
tory and business doubles.
