Jim Berglund’s Lesson 38

♠
♠
Lebensohl by responder over a strong NT was invented so that you
can compete better or show game forcing hands immediately.
The bad part of Lebensohl is that you must go thru a relay to find out
partners real suit so when RHO competes you might never know that
you have a fantastic fit. In today’s game , the opponents always seem
to use their toy to disturb your NT but RHO is getting into the act more
& more to re-preempt the auction.
Jeff Reubens from the Bridge World thought it was a better idea for
partner to announce the suit directly with a transfer but your strength
later with a D.S.I.P. double or a Q bid or by bidding again. You build
your system around hand evaluation concepts.
Rubensohl was built on the transfer concept.

2♠
3♦
4♠
1NT
?
With ♠xxx ♥AQxx ♦AKxx ♣Kx it might be a good idea
to bid 5♥ since partner has announced hearts with
her transfer .
Partners hand is ♠x ♥Kxxxxx ♦xx ♣Q10xx but playing
Lebensohl he would have bid 2NT so with the same
4♠ bid by RHO the partnership is poorly placed.
Neither side is aware of the huge heart fit !!
Competing for a partial is important as double partial
swings are expensive.

Example 2.
You hold ♠xxx ♥Ax ♦Axxx ♣AKxx and guess that
partner was competing in hearts so you pass.
Wrong , partner had diamonds .
With ♠x ♥xxx ♦QJ10xxx ♣Qxx , you are on a hook
for 5♦ but you sell out for 3♠ unaware of your huge
diamond fit.
♠ The device Rubens suggests to prevent RHO from
jamming you is to replace the Lebensohl structure with
a transfer structure.
♠ This allows the NT opener to know the suit immediately
♠ By the simple act of accepting the transfer , he can be
♠
♠
dropped by partner when his intention was just to
compete.
When partner’s intention was to force , he can bid
game or Q bid or bid Blackwood or whatever.
Another brilliant part of this structure is that you can
define meanings to transferring into their suit.
♠ Transfers also allows the concept of
“super accepts” which can also be used in
this structure
♠ Usable bidding with two suiters is
preserved with transfers along with the
super accept understandings.
♠ All this & the contract is right sided !!!
♠ When the opponents bid artificially
or bid the
minors naturally, Lebensohl or other
understandings are on.
♠ When the opponents make artificial doubles or
2♣ bids showing a single suit, we just ignore
them and systems are on.
♠ A double on an artificial 2♣ bid is simply
Stayman or cards ( partnership preference ) .
♠ Rubensohl applies after a 1NT overcall also with
RHO interfering.
♠ The underlying new concept with
Rubensohl is the trick of transferring
into their suit.
♠ This is Stayman or a 3NT bid without a
stopper.
♠ The opponents must be playing a
natural or quasi – natural system
before Runensohl comes into effect.
After a 1NT opening bid and a natural 2♥ or 2♠ overcall (also
playable if the overcall shows the bid suit along with an unknown
minor

Example 3.

S
1NT
2♥
?
Double= penalty , D.S.I.P on terrorist vul (us vul them not)
2♠= Natural, not forcing.
2NT= Transfer to 3♣
3♣ = Transfer to 3♦
3♦ = ( transfer to their suit ) Stayman or 3NT without a stopper
3♥ = transfer to 3♠
3♠ = both minors (eg ♣x ♦xx ♥ AQxxx ♠ KJxxx)
3NT= Natural with a heart stopper
4♣ = Gerber (for aces only)
4♥ = Transfer to 4♠ (If followed by 4NT, Keycard Blackwood)
4NT = Natural
Note: Transferring into their suit should also be a way of
asking partner if he has a stopper in their suit as well as
Stayman.
When the NT opener does bid a 4 card major & partner
now bids 3NT he does not have a stopper.
When you do not do either , scrambling for the best
contract commences.

1NT
2♠
?
Double = penalty - D.S.I.P. (Do Something Intelligent, Partner)
2NT = transfer to 3♣
3♣ = transfer to 3♦
3♦ = transfer to 3♥
3♥ = Stayman or 3NT without a stopper ( transfer to their suit)
3♠ = both minors
3NT= Natural, with a spade stop.
4♣ = Gerber
4♦ = Transfer to 4♥ (If followed by 4NT, Keycard Blackwood)
4NT = Natural
Responses are consistent with the heart overcall.
With this treatment , the transfer always shows
the suit immediately, in case RHO interferes.
♠ Applies when partner makes a 1NT
♠
♠
overcall and they interfere.
You can give a meaning to transferring
into the 2nd bid suit if there is one.
D.S.I.P. doubles rather than penalty
doubles apply in these auctions also
when they interfere after a 1NT
overcall by partner.
Understandings are also necessary of RHO gets in
the act , but these are just common sense. As per
other Bridge principles , if they double,
♠ Bidding is the weakest action.
♠ Pass denies a fit and leaves room for a penalty
double if there is one .
♠ A XX is punitive & denies a fit with your suit.
♠ A Q bid or 3NT are super accepts even with RHO
interfering.
