D.S.I.P. - Responding to Overcalls
PITBULLS:
Another
one of the many uses of a D.S.I.P. double is responding
to overcalls. There are many auctions where a simple raise of partners
overcall will just not do. You have too much defense for a simple raise & Q
bidding brings you to an uncomfortable level. Also I am a strong advocate of
differentiating between 3 card raise and a 4 card raise of partners overcall.
With D.S.I.P. double understandings , a Q bid could tend to show a 4 card raise
if we have a D.S.I.P. double available.
Support doubles to overcalls have really not been invented
but with D.S.I.P. doubles , we can have this flexibility. They can tend to be
responsive or
a fit for partner when clarified later.
Here
are some sample auctions.
These doubles with the top of a responders range for a raise , obey
D.S.I.P. theory. You want to compete but you have defense . The
corollary of course is if you bid directly it just means that you have paid
your card fees. The D.S.I.P. double is ambiguous in this auctions as you are
just showing “cards” . However , you can clarify later by supporting partner.
If the overcaller makes the “death response” by returning to her suit the
auction quite often dies at that level.
“Playing the vulnerability” can mean some
pretty light overcalls. Making a D.S.I.P. double in these auctions means you
have done your duty. Do not punish partner by Q bidding and driving her to
game. The D.S.I.P. double describes your hand within a pretty good range. Give
partner a chance to bail out. A D.S.I.P. double is just not limited to the
overcaller bur responder can use the tool also.
In hand 4 where you are making a D.S.I.P.
double at the 3 level minor implied , quite often it will be a Western Q trying
to get the hand to 3NT. The D.S.I.P. double serves as a Q bid when they have
taken away your room. When 3NT can be to play , it usually is.
