Hand Evaluation – Bidding Freedom
PITBULLS:
When partner has had a chance to make a D.S.I.P.
double in a competitive auction but does not , all
gloves are off. You can bid your suit , a new suit , good-bad 2NT or
Q bid without the chance of partner punishing
you. Why , because the negative inference that you did not make a D.S.I.P double comes into play . You can not be
bidding constructively or
else you would have doubled initially.
With this “protection” comes some freedom
in your choice of bids.
BJ
Trelford used this inference to invent
a D.S.I.P. Q bid . This Q bid meant Do
Something Intelligent Partner as I want to compete somewhere but without defensive values or a preponderance of HCP’s. I can not hold values or I would have made a D.S.I.P. double
instead. BJ had ♠Qx ♥QJ109 ♦109876x ♣x , the
auction ( everybody vul) went 1♠-P-1NT-DBL
2♣-2♦-2♠-P
P-? .
A double here would be a classic D.S.I.P. double saying I have defense & would
like to bid again. BJ was not sure if he wanted to compete again in diamonds or hearts but he did not want to sell out
to 2♠ as we
should hold half the deck. 6-4’s
are nice playing hands so we should not get punished at the 3 level. On the spot he bid 3♣ , which he meant
as take some action
partner but I am weak , distributional so do not get too excited. A D.S.I.P.
double without defense without
actually making a double !
The
D.S.I.P. double inference allows
you the freedom to bid your distribution
to the hilt. Partner will not take another
bid based on your bidding. Bidding new suits , Q bidding , NT bids can never be forward going. This freedom is
nice for pushing them up without
fear of partner making penalty doubles or “taking you seriously” . This means
that partner does not take you for extra by bidding again. You can compete
without fear of misleading partner which invariably happens not playing
competitive doubles. Free bids do not exist to show a good hand or else you
would have doubled or used the “good bad 2NT” at the two level. I think this is
why Tom Gandolfo likes D.S.I.P. double
theory . These doubles give him still another
excuse to bid while keeping
partner quiet
