Hand Evaluation - Partnership ( Neg Dbls )
PITBULLS:
To play negative doubles , D.S.I.P. competitive
doubles or forcing pass theory properly , you must know the basics of penalty doubles.
Penalty doubles are a Bridge partnership
operation. When I first learned penalty doubles ,
Margaret Tomlinson told me something I have never forgotten. Leave penalty
doubles in when you have the hand partner can reasonably expect on the
auction. The key words are what partner
can reasonably expect. With negative double theory ,
you make a re-opening double with a hand that partner can reasonably expect on
the auction also.
Again the HCP location rather
than the HCP total
is a deciding factor. You never get away from HCP hand evaluation in Bridge.
You cannot just make Bridge decisions based on a HCP total & the fact that
you opened on that total. Partner reasonably expects your HCP's to
be in the suit you
opened when you re-open with a double .
That is a given as he measures whether the auction is a misfit by that HCP indicator. When your
points are concentrated in another suit ( especially
long ones ) , this is something partner does not expect. You decide
to make a prepared bid ( everybody vul
) with ♠x ♥Kxxxx ♦AKxxxx ♣x
& open 1♥ instead of your longest suit. The
opponents bid 2♠ so around to you in the re-opening chair .
Do you protect your partners penalty pass ? With your
10 HCP & the opponents have stopped in 2♠, partner
has an obvious penalty
double.
Let’s go back to Margaret's
comment . Can partner reasonable expect you to hold a
6-5 in the reds with 70 % of your values in an unknown 6 card ♦ suit ? Therefore
, I would pull Margaret’s penalty double of 2♠ to 3♦. Margaret with ♠AQ10x ♥x ♦Qxxxx ♣Axx
or similar hands would drive the hand to +1370 in ♦'s.
However change your hand to ♠x
♥AKJxx ♦K109xxx ♣x & most experts would
be tempted to double even with a 6-5. Why ? This hand
is drastically different from the first hand. Your HCP's are located where partner will expect them
to be for opening lead purposes & misfit
hand evaluation for partner. On this hand ,
2♠X has a chance of going for +500 & you cannot make anything your way !
You win the heart lead & switch to your stiff ♣. You take 2♥s , 2♣'s off the top,
possibly 1♦ & how many down they go is
dependent on partner's trump holding. The double is still swingy as partner
does not expect a 6-5 but at least you have quick tricks where partner can reasonably
expect them. However , since it is a major suit held by the
opponents & doubling them into game is a disaster , I would take out
insurance & bid 3♦ with both hands. It the bid were a minor
overcall , -180 is not a disaster so that will enter the equation.
Penalty doubles has
played by the masses is the most single handed bid ever devised. However , when you bring Partnership Bridge in the picture ,
penalty doubles work . I based the entire theory of D.S.I.P. competitive doubles around "two heads are better than
one " for converting penalty doubles. When you re-open with a double in negative
double theory , you are helping partner out. However,
have what partner can reasonable
expect as per Margaret’s wise words to me 40 years ago. You will have a lot
fewer -870's which is what the doubler in our auction
received. She had ♠x ♥Kxxxx ♦AKxxxx ♣x
so could partner reasonable expect that hand ? Garbage
openers lacking quick tricks is horrible for negative double theory
, penalty doubles , competitive doubles & constructive
bidding . This hand was not
a garbage opener in that she had 2 1/2 quick tricks. The 2 1/2 quick tricks
were just located in the wrong
suit however so the disaster unfolded. Location
, location & location is more than a real estate platitude. Evaluate
HCP's as to quick tricks & their
location.
A Tormentee
was too cautious in her negative double approach recently. She opened 1♠ with ♠AJ10xx ♥Kxxx ♦Kxx
♣x playing with Mathew Greenways. Perry overcalled 2♣ so around
to the Tormentee. same
scenario as the other hand above. You have opened on 11 HCP's so the only
reason 2♣ is passed around to you is partner has a club trap. You have a light opener , not a garbage opener. You have HCP's measured in
controls & HCP's in spades where partner can reasonably expect them. You do
your duty & double & Mathew holds ♠x ♥AJxx
♦J10x ♣KQ1087 so +500 or more . The tormentee
re-opened with 2♥ as she felt she was not strong
enough to re-open. However , that is not the litmus
test for negative doubles. Would you leave in a penalty double of 2♣ ? Can partner reasonably expect you to have this hand for
an opening bid ? Yes , to
both these questions. You are distorting your hand by bidding 2♥ as you are describing a weak 5-5 in the majors anyway. Also 2♣X making is not game nor a
disaster.
