Hand Evaluation – Toys & Doubling ( ownership )
PITBULLS:
Doubling a suit in a forcing auction can not be penalty
except when partner has pre-empted or bid a pre-emptive
toy ( captaincy considerations ) . One of
the rules of D.S.I.P. theory is whenever one of the partners has pre-empted , old fashioned trump stack doubles apply.
When partner makes an unusual 2NT bid or a Michaels bid even though its an
either/or bid it is assumed to be a pre-empt
in the initial instance. The double must be reserved by the “pre-empter” to show the strong hand ( either
/ or) . The double by responder is
deemed to be always penalty ( captaincy ) .
My
partner held this hand . ♠Jx
♥Kxx ♦AKJxx ♣xxx nv vrs vulnerable
opponents with the auction proceeding 1♦-2NT-3♠-? . The 2NT is a two suiter
which is either very strong or weak but never intermediate. Partner can not double 3♠ as the bid is
forcing. A double here should be competitive as they own this auction.
This
is 3rd case D.S.I.P. theory . The vul opponents own the
auction so we are the intruders.
The pre-empter is allowed an “action double” with an extraordinary hand
in light of her bidding ( violating captaincy ) . With
my hand , I would love to sacrifice to 5♥ after partner has
bid hearts but I should not do it single handedly. As I am the pre-empter , I should make an “action” double saying I want
to bid 5♥ but I have defense that I normally would not have. Partner
happily converts so we get +500 instead of –500 .
In
any of the other 3 vulnerability situations , the pre-empter is
only allowed to double ( violate captaincy ) , when she has the strong hand. This one vulnerability ( the sacrificing vul ) gives an
opportunity for an action double as the auction
has shown the pre-empter can not have the strong hand.
What
if partner had ♠xx ♥xx ♦AKJxx ♣AQxx ? He would bid always
under the assumption that we have the weak
hand for bidding our toy.
If he has strength , he should Q bid instead of leaping to game .This describes
the nature of his game bid , puts
me in the picture so I do not do something stupid if they bid again. In rare cases , I may hold the strong hand for the toy so leaping
to game with a good hand should
be avoided.
Say I
had the strong hand ♠KQ ♥AQ10xx ♦void ♣KQJ10xx , they open 1♦ so I bid 2NT strong
& they bid 3♠ non forcing.
Partner has ♠Jx ♥KJxx ♦J10xxx ♣Ax so he should not just
bid 4♥ as that may be bid
on nothing. He has an obligation to Q bid first in case I have the “or” hand . I jump to 6♣
which gets converted to 6♥ so we get to our
slam. In auctions where the systemic toy is either / or, a Q bid by responder should describe
the defensive hands. This is catering to
the trump stack penalty double. Jumping
through hoops I believe it is called J
The
reason why responder must make the
Q bid in these systemic auctions
is because the ambiguity of the toy as being either/or .
♠AKQxx ♥AKJxx ♦x ♣xx the auction goes 1♦-2♦-3♦-? ♠Jx
♥Qxxx ♦Axx ♣Axxx . What is a 4♥ bid
? Should partner move because he has the stronger hand
? Maybe partner assumed you had the weaker hand so are bidding pre-emptively with nothing ♠xx ♥Qxxxxx ♦x ♣xxxx. Responder should
always make a Q bid going in, then
bid 4♥
with a
good hand. You may get to grand slam
in hearts despite their interference.
