Hand Evaluation – Overcalls
( T/O Doubles & Transfers )
PITBULLS:
Experts design their system based on hand evaluation concepts. Transfers are a hand evaluation concept so
there is no reason to just use them after a strong NT. They are far too useful
for that particular limited application. When the opponents have made a T/O
double of your major , they have already screwed up your auction. When you have a one suited hand that is 10 HCP+ , lower in rank than partner’s major , you must distort
your hand by redoubling.
You cannot bid your suit at the two level in your suit as this is non forcing. This is bad because the opponents can
initiate pre-emptive action so you may have
to introduce your one suited hand in a misfit
auction at an unsafe level.
Which bid in Bridge allows you to show a one
suited hand that is either very weak ,
intermediate or strong
? If you guessed the transfer ,
move to the head of the class. Playing transfers after T/O doubles of a major makes as much sense as playing them after a 1NT opening. You need rules for “super
accepts” & breaking the transfer
but they are handy. Transfers help define the
redouble making it now punitive with no fit nor
single-suited hands.
Disturbing the opponents’ auctions are
a good tactical ploy. When partner opens a major ,
the opponents make a take-out double
, you can effectively use transfers as
a two pronged tactic. You can mess up their T/O double & describe your hand
better to your partner. You sacrifice the
1NT as natural ( after a major only ) which is
not a great loss as with hands with no fit
for partners major under the
values for a redouble , it is usually better
to defend. Let the opponents play
the misfits. When you have a top end 1 NT bid , you can always redouble & bid NT at your
first opportunity. A 1NT bid showing clubs
pre-empts them out of their 1NT
response. A 1NT bid , in my opinion , just rescues the opponents especially when they are vulnerable. Think about it. You have no fit with partner with 7-9 HCP. This
means you out gun them possibly 22-18 ( giving partner
her 13 HCP ) & it’s a misfit auction.
Why bid with those hands ? D.S.I.P. doubles later on in the auction will show values just
under a redouble so penalty
conversions can take place or
a scramble to a partial.
A transfer can be used like
a relay to give two meanings to the same bid of a simple raise
of partners major. When you transfer into her suit it is constructive , if you
make a simple direct raise , it is
not. You keep the auction at the two level & describe two different hand types.
Susan tells me that Klimo has added a twist to these
bids. He adds an or element to the transfers. They are either , a simple raise
in partners major with values in the transfer suit or the single
suited hand as described. This understanding clarifies simple raises
& shows where you live. For
game tries & defensive purposes.
This can not be bad J .
“Showing where you live” or determining how well hands fit is a time honoured hand evaluation technique that is used for game tries. Kokish game tries are defined as showing where you would accept a game try. These transfers with a fit follow the same principle. You show where you live with a transfer simultaneously showing support for partner’s major . Excellent bidding. J
The transfer element hurts the opponents ability to compete. They either must go to a higher level with their suit or double which gives us more room to compete & allows us to redouble to show values. There is a case for playing transfers over any opening bid but we only play them after a major opening. If partner opens a minor , 1NT to play make sense & you can always get your long suits in at the one level. It is the rank problem with a major suit opener that needs to be fixed via a transfer.
