Hand Evaluation – Doubles ( D.S.I.P. Light )
PITBULLS:
Instead of playing “full blown” D.S.I.P. competitive double theory , which in my
mind is only for experts
, you can try a “depending on
context” version of competitive doubles.
The ground rules start off the same in that we must be competing for the
contract so we do not “own the auction” where Forcing Pass theory would kick
in. Next , we allow the context of the bidding to determine whether a double is a
trump stack penalty double or not.
In other words , trump stack penalty doubles exist with some competitive auctions. I
call this the “matchpoint
version” of D.S.I.P. theory or
D.S.I.P. competitive
double light in honour of Lite beer drinkers
everywhere. .
Here are some ground rules for “depending
on context”. When the opponents bid like they own
their suit , they do , so trump stack doubles do not exist in those competitive auctions. Give the devil hisr do. These
auctions are usually jump raises or jumps
to game. When the opponents bid & raise their suits ,
trump stack doubles no not exist either. The over / under rule applies in all competitive auctions. When we are
behind them , the double is penalty. When we are in
front of the suit , the double is competitive. If the auction is a “misfit” auction indicated by either sides bidding , the double is trump
stack penalty even in a competitive auction. Re-opening doubles
are never penalty.
Doubles in competitive auctions at
the 3 level or above are trump
stack penalty. All normal competitive “fit auctions” at the two level or one level , the double is never trump stack penalty. The doubles just
means you have “cards” so do not want to sell
out cheaply. When the doubler has never
limited her hand , the double is trump stack penalty.
1♣-1♦-1♥-P
1♠-2♦-X This is penalty as
the 1♥ bidder is unlimited &
as opener has bid two suits , you should be captain.
When one partner is captain of the auction ,
the double is trump stack
penalty. So if you have described your
hand already via a pre-empt , a limited bid , a 1NT rebid
or opener etc , partner is the captain of the auction. All her doubles are
trump stack penalty.
When they balance
, all doubles are penalty when we are behind the suit & competitive when
we are in front of the suit. If partner is just trying to clarify the nature of her opener , T/O Dbl , negative Dbl or overcall, the double is just cards not penalty. When they are at the 3 level or higher they are
more co-operative penalty however.
You still need judgment to read the context of the auction to determine
whether a double is trump
stack penalty or not. I do not
like trump stack doubles in competition
period but if you do ,
try this form of competitive doubles above . The reason I do not like trump
stack penalty doubles is that ambiguity , the killer of Bridge bidding is introduced. I like the clear message that
these doubles in competition show “cards” , not values
in their suit.
The double is too useful
a bid in competition to be restricted just for trump stacks. Susan says she avoids trump stack doubles at lower levels with
her partners . Playing with me quite often she recognizes from the context of the auction that my double cannot be trump stack penalty. She now
attempts to do something intelligent J.
Use
the double as a descriptive bid to show
strength in competition rather than a trump stack. A double can also
be used as a Q bid or Western Q bid , when you are jammed by the rank of their suit. Do not just bid a suit & expect
partner to be clairvoyant that you have 18 HCP for your bid this time rather
than the 12 HCP in the past. A double gives partner more options &
conserves bidding room. You do not
pre-empt your own partner by bidding a suit , instead
use doubles in that context to avoid pre-emption. Balance of power doubles
should be recognized as such , rather than just being
a trump stack. Play the odds that the opponents hold their suit.
Action
doubles after you have made a pre-empt is
still better than “St. Alberting”. When you want to
bid again when “captaincy” dictates you should
not ,
do it with an action double. At least , the blame can
be transferred to partner which is a good thing. I do not know if you have been
reading the articles on full blown D.S.I.P. double theory ,
but there are parts that are very sound in theory so you can bring those into
your own system without going whole hog. Call them just competitive doubles
rather than D.S.I.P. competitive
doubles as I have copyrighted that name
.L Perry & play D.S.I.P. Lite ( go figure ) which looks
good on our convention card & meshes with his beer drinking preference..
