D.S.I.P. Pre-emptive Auctions
PITBULLS:
The opponents pre-empt to make life difficult for you
. They cramp the bidding and make you guess. If you guess wrong it can be
expensive. D.S.I.P. doubles are a good counter measure for pre-emptive
maneuvers by the opponents. First
of all throw penalty doubles out ,
when one partner raises the pre-emptier.
Penalty doubles just do not exist. If you have their suit , pass and wait for
the re-opening double . A double says I have cards
and no clear cut action. Tom
Gandolfo had a hand tonight that shows D.S.I.P. theory in action at the 4 level.
3♣-3♥-4♣-? ♠ K10x ♥ 9xx ♦109xx ♣
AJ10 You have
defensive values but no clear cut action . Why guess at a 4♥ contract ? You double which gives partner the
maximum number of options. I held Qxx AQJ10x
KJxxx void so over the
double I bid 4♦
. Tom is at the 4 level
anyway so he bids 4♥ which
gets resoundly doubled. I know I can not stand the heart tap because Tom can not
have 4 trump on this auction. I bail to 5♦ and a disaster is averted as they may not even
double that contract ! If partner does not make a D.S.I.P.double and guesses
the 4♥ is the spot , I would never pull 4♥X . It goes for a telephone number on this particular
hand and 5♦ is down one ! Not bad against –130 in clubs !
When
the auction has prevented you from describing your hand & raising partner ,
D.S.I.P. doubles just show cards and no clear cut choice of bids. Bidding in
these auctions are quite often just straight gambling by guessing. D.S.I.P. doubles
help alleviate the guess and even allows partner to pass with a non offensive
hand and wastage in their suit. As long as the criteria for D.S.I.P. doubles
are there , a double will assist partner. We do not own the hand or partner has
no idea that we own the hand ,
D.S.I.P. theory applies. The last
statement is important . If you had 16 HCPs in the above auction , how does partner know it ? Without a great fit double anyway and then Q bid . This reserves the direct Q bid for fits only in these pre-emptive auctions.
Forcing
pass auctions only apply if it is obvious to
the partnership that they own the
auction. If one partner is in the dark , D.S.I.P. double theory is
the default. Trump stack doubles
have no place in competitive
bidding.
