Hand Evaluation – Systemic ( 1NT
& Doubles )
PITBULLS:
When the opponents
pre-empt at the 3 level over your INT , it is best to play negative
doubles . Doubling them for
penalty with their long suits is just not “cost
effective” .
It is better to find a major fit or get to your 3NT contract especially when
you play the vulnerability. For years , a double of a
natural bid at the two level was penalty . The modern trend is to play them as negative with strict suit requirements. I disagree with that
treatment. I prefer the double to show cards
7 HCP & upward with no
clear cut action available. If they
are vulnerable & we are not , the
double is old fashioned penalty.
In other words , a D.S.I.P. card showing double most of the time. A trump stack double is
shown by passing or bidding your
3NT game. The D.S.I.P. double in these auctions conveys the meaning of “I do not what to do” so
over to you for your
input.
This understanding changes your Lebensohl or Reubensohl treatments. A direct jump to 3NT now shows a stopper . Without a stopper , you just double their suit & pull partners suit to 3NT if the HCP’s warrant it . Partner now knows you do not have a stopper , so bids accordingly.
If
the opponents bid is systemic but natural ( maybe showing a second suit ) , the double is still
D.S.I.P. showing “cards” . If their bid is artificial
, the double means let me at their invisible suits. We Q bid their invisible
suits & bid their artificially suits naturally with forcing playing hands. D.S.I.P. doubles include the hands that fit
the requirement for negative doubles but are all inclusive in that there is no specific suit
requirement for the double.
The
only exception to this treatment is the trump
stack double without compensating HCP’s . This
hand is shown by a t pass & hope partner
re-opens. With their suit & HCP’s , you might just choose to bid a vul 3NT rather than passing. The only downside to this
system is the requirement for partner to re-open after bidding 1NT . He should double with shortness in their suit or otherwise pass. If responder has a trump
stack double & the 1NT bidder passes , at least a plus is picked up !!
I had
a hand tonight ♠AJxx ♥109x ♦Q10 ♣J10xx , partner opened a
strong NT with RHO overcalling 2♥ . What do you do ? You can pass or
bid 2♠ to compete. Playing D.S.I.P. doubles , you can double .
You hit partner with 17 HCP’s & AJxx of hearts !
Just 800 for your side against a partial making your way .
A bad bidder just got caught speeding when you might have rescued them.
Say
you had ♠xx ♥AJx ♦KQxx ♣Qxxx , partner opens a NT
with RHO bidding 2♠ . Without a D.S.I.P.
double in your arsenal , you would leap to 3NT to show
you do not have a stopper. Here
you can get the best of both worlds . If partner has spades , they play it there doubled for a huge number . If
partner does not have a spade stopper, you find your fit at a low level so
maybe get to a magic 5 of a minor game or a 4 heart game. If partner has a
spade stopper , you get to your 3NT game. Win , win and win with a card showing double at the two
level.
Partner
should always bid 2NT with a stopper in these auctions after a
D.S.I.P. double unless he wants to convert
for penalty. Otherwise , he scrambles by
bidding his lower ranking 4 card suit or
a 5 card minor if dealt that. You may find your 4-4 major suit fit by scrambling . If
partner has a major & game going values , he may
have chosen an initial Q bid as Stayman rather then doubling. In D.S.I.P. auctions, we are probably just scrambling for a safe partial resting
spot. Do not over use the D.S.I.P. double , if you
have a safe alternative bid. Action after a D.S.I.P. double is pretty straight
forward. Partner bids game if he feels its there but
the rest of the time we are just trying to find a suitable resting spot.
Converting for penalty is also a frequent
option.
The
D.S.I.P. double is handy when your side overcalls
1NT but they interfere. Tom Gandolfo had a hand that shows this bid
in action. ♠xx ♥Kx ♦xxxxx ♣Axxx , they open 1♠ nv
& vul partner overcalls 1NT . RHO bids 2♠ so now what ? You could be cold for 3NT or a partial or you could
extract a +300 penalty. A D.S.I.P. double to the rescue ! You double ,
partner has 17 or 18 HCP so he will probably opt for a vul
game . 2NT is not invitational by the 1NT overcaller
after a D.S.I.P. double as that is redundant ( the
D.S.I.P. double is already invitational
) so the 2NT says pick a suit so lets play a partial. Alternatively you could play Reubensohl here. A new suit by the 1NT overcaller , also suggests a
partial. I had a minimum with 5♥ , so I bid 3♥ & we collect
+140. If they compete to 3♠
, they are in
–300 to –500 territory.
If the opponents bid a new suit after a 1NT overcall , a double is still D.S.I.P. It just means I have cards so do not know what to do . It is surprising how frequent these auctions come up. Good players like bidding on nothing in these auctions , so the D.S.I.P. double can give you lots of options. As usual in D.S.I.P. theory , the double replaces the old fashioned invitational 2NT bid. The 2NT bid is always Lebensohl/Reubensol even if they are raising partner or switching suits. The D.S.I.P. double removes the ambiguity in these auctions.
The
sandwich position is where
D.S.I.P. doubles can really assist the auction. Nick & Judy shows the confusion that can rise with “traditional” penalty
double thinking. Nick held ♠AK9x ♥KJxx ♦Qx ♣10xx & opened a weak NT . Tom passed , Judy bid 2♣
which is non forcing Stayman in their system . I bid 3♠
so Nick can not make a penalty double as the 2♣
bidder may hold nothing. Around to Judy , she holds ♠x ♥10xx ♦K10xx ♣AKJxx . She is maximum as possible for not
making a forcing 2♦ call . She is in
front of the spade bidder , so a trump stack double is
unlikely. A D.S.I.P. double is probably the most flexible bid. Judy at the
table bid 4♣ , went 1 down when 3♠X goes for 500. Stan Cabay
says a “re-opening double” is never for penalty. The over/under
rule should take precedence. Do not double for penalty in front of the suit.
When you double a strong 1NT or a weak NT , forcing passes are turned on thru the two
level. Judy Gartaganis taught me a good way of
handling these 1NTX
situations. After a penalty double of 1NT ,
a double of their natural run out suit shows
cards not penalty. Forcing passes
are on thru 2NT so the original doubler must re-open with
a double. Kiz Fung came up with the notion that all
penalty doubles of 1NT
by the opposition should turn on forcing passes thru the two
level. This idea has merit but should be discussed with partner as
it is not standard.
Kiz’s example was a double of a sandwich NT should
turn on forcing passes. Why not ? It could simplify auctions .
