The big potential of the jacoby transfers is far from being exploited. In order to make the best use of theese, all one have to do is to replace the standard
and expensive openings 1NT and 2NT by the cheaper openings 1
and
2. Therefore the openings 1
and 2 include a balanced hand, with 15-17HCP for opening
1 and 20-21HCP for opening 2
The natural and conventional openings 1 and
2 have been gone.
The openings 1NT and 2NT become free and can be used as you like.
The system uses direct and indirect answers for Jacoby transfers, Stayman, minor suiters ans two suiters. This new concept enables a strong enlargement of the bidding field and therefore a greater accuracy of biddings and auctions.
A direct answer is an answer which shows directly his meaning.

** Requires always completing to 2. Here is a new important concept what may called "Presumption denial" : The opener must always complete to 1NT because the responder has
theoretically a very weak 6 suiter and requires the opener to bid and play
2. But if the responder do not pass after this bidding
2 but makes any new bidding, his hand differs
entirely from this presumed. Please read farther why and how
at "Extensions of the opening 1".

If he had just 16HCP and balanced hand, the responder would have bidded first a relay, then he
would have bidded aquantitative Blackwood 4NT after completing 1NT by opener.
See below indirect answers.
Of course the responder has also at his disposal the natural biddings 4 and
4 limited to game if he has a reason to play himself.
NB: Please see more details at 'The main auctions'
An indirect answer begins always by a relay
1 or 1
as first answer. The opener must always complete this answer to 1NT.
The meaning of an indirect answer is given directy by or from the first responder's rebid.
The choice of first relay by responder is very important.

and 2
If the opener is not fitted in major he must complete to this one. Completing to 2NT would be
dangerous, whithout knowing the color of singleton.
But when the opener is fitted in major, the game is possible if the singleton is favourable : He may bid an asking auction in order to know its color.
*** 2 and 2NT.
Ambigous. Undeterminated major singleton. The opener must complete in his minor 4° suiter if he has
one, if not in the minor 5° suiter of the responder, even with
2 cards. After completing by opener :
The responder passes if he has at most 6/7HCP
The responder bids his major singleton if he has at least 8/9HCP.
After bidding major singleton by responder, the opener bids 3NT if he has a good guard in the color of
singleton and is able to play 3NT (If not he rebids his minor.)
The responder accepts the contract 3NT or closes to minor game.
But after any opener' rebid (for instance 3NT), if the responder has at least 16HCPD he bids an exclusion Blackwood excluding the color of the singleton or the void that he has yet bidded.
**** 3 and
3.
Ambiguous. The opener must
complete to his best major, then the responder passes if he is very weak.
But if the responder makes any rebid after the opener's completing, he has at the contrary a strong
55 major two-suiter, but with no Ace. As rebid, the responder bids his first control.

Lead orientation. The responder has no major suiter, and a balanced or hajf balanced,
with 9-10HCP and with queens.
After opening 1 if the responder has 9-10H without
major suiter. He knows that the contract to play is 3NT.
Usually he bids a relay then after completing 1NT he bids 3NT, to play by the opener. But sometimes, for instance with 2 or 3 queens, it is his interest to
play himself 3NT instead of the opener, and to receive the lead. For instance in case of frequent leads
with KJXxx, AJXxx, VXxxx.

* Oblifed completing
** Without any major suiter
This sequence is the equivalent of a classic auction. When using it, the choice of
1 or 1
relay is irrelevant. But it is possible to be very more precise if these relays are used wisely:
If opener has only 16HCP and responder only 8HCP, and neither player has a 5-cards- minor suiter, the potential 3NT contract is very uncertain and likely to fall flat. This is also why, after opening 1NT, many good players pass with 8HCP if they don't have a 5-cards minor suiter.
Conversely, if opener is maxi with 17HCP while opener has 7HCP and a 5-cards mpnor suiter, the 3NT contracthas a good chance of success.
It is generally accepted that to declare a 3NT contract, a minimum of 25 HCP or 25 HCPL (Honnor more 1 length Point) isrequired in the line, i.e., 25 HCP without a 5-cards minor suiter , and 24 HCP more a 5-cards suiter.
Responder may neither indicate his 5-cards minor suiter if he has one, nor indicate that he has not. However, it is very important that he be able to indicate the true value of his hand, taking into account whether or not he holds a 5-cards minor suiter.
For his part, the opener, knowing the real value of his partner's hand, must also take into account the real value of his own hand, taking into account a possible 5-cards minor in his hand.
They involve a differentiation between

The opener knows that the responder has at least 8HCP and 5 cards in his major. He has no problem to tell together his force and his distribution (fit or no fit)
If the opener has the fit with 4 cards in the responder's major, he completes at level 3, whatever with only 15HCP or 16-17HCP
He begins by bidding a relay answer in the opposite major, then after the obliged completing

For memorization of these 2 totally artificial sequences, after
relay 1 or
1 and the opener's 1NT correction, the responder's
rebid is always 2.
The responder bids an indirect Stayman 2 :
He bids first the opposite major (this one where he has no 4 cards) as relay. Then,
after completing 1NT he bids an indirect 2 Stayman
which shows clearly his major-suiter of 4 cards.
When the opener is fitted with 4 cards he will play the the contract.
When he has no fit in responder's 4 cards major-suiter, the opener will play also the contract
at NT

* The opener completes to 2NT or 3NT according to his strenght. If the opener has corrected to 2NT, the responder bids 3NT with at least 10HCP.
** The opener completes to the major suiter of 5 cards if he has the fit, if not he bids 3NT.
Remarks :
The opener must never overstep the level 3 ou 3, even if he
is maximum. In order to enable the responder either to pass, either to close at the game,
and above all to bid a control if he has a slame hope.
Theese answers 3
and 3 have nothing to do
with the mixed 4M 5m two suiters such as 4 5 or
4 5. Theese last biddings are are explained in paragraph just above

* Obliged completing to 2. This response 1NT
presumes a very weak hand with a six-cards suiter
in in order to let play 2 by opener instead of 1NT.
The opener must complete to 2, then the responder passes.
But if instead of Pass, the responder makes any bid after 2, he has a quite other hand, the strenght of
structure of which is showed in this 2° bid. By
this context, the responder shows a five-cards major suiter with 7-8HCP and 1 singleton whose colore is undeterminated.
Knowing that a singleton exists, the opener may ask its color, by means of the technical following auctions :
| 1 |
1NT (Transfer to ) |
| 2 (complete) |
2
(avec 5) 7-8HCP and singleton |
| 2
(no fit ) * |
|

|
| 2NT(Fit ) What singleton ? |
3
(singleton ) |
| 3

|
| 3

*The responder passes, of course.
The biddings 2NT by opener are obviously not natural. It would be impossible to play NT with a singleton when both players know the five-card major suit is fit. Especially since the opener cannot consider a NT contract without knowing the color of the responder's singleton.
After learning the responder's singleton, if the opener has a fitted major, he decides. He corrects at the 3-level in the major suit with a fit if the singleton doesn't interest them. He bids game otherwise. And the major suit contract, whether not with a fit at the 2-level or with a fit at the 3-level or 4-level, will always be played by the opener.

* With a 54-card minor suit with 15-17 HCP and two major doubletons, the opener normally
opens with 1 and the sequences are normal.
With a singleton or major void, the opener also opens
with 1, but reveals their irregular
distribution by refusing the normally expected correction, by naming their 5-card minor suit.
The responder is thus immediately alerted and reacts accordingly.
or 1The opener names his longer minor-suiter
After these responses, which promise at least 8HCP, the opener also names his longer minor-suiter at level 3, unless of course he has a 3-card fit in the responder's major-suiter, and therefore a void in the other major.
(direct Stayman)Opener without a void
After this response, which promises two majors and at least 8 HCP, the opener responds 2NT or
3NT without a void.

The opener responds 2, then :

Therefore, due to higher level, there are some differnces, for instance
when the responder has 2 major suiters 54 and minor slam biddings.

**** With just 12HCP, the responder bids first a relay, no matter 2
or 2, then bids 4NT after completing to 2NT by opener. See below the indirect answers.
The relay answer 2 or 2 requires always the opener to complete
at 2NT. After 2NT the second bid of the responder is his indirect answer which shows the strenght and the frame of his hand.

After relay 2 the responder has a singleton in

4, forcing gameFor the 54 major cross-suits, there are indeed two answers,
3 and
3. This allows the major fit
to always be declared by opener at the economic level of 3, thus allowing for possible checks by
responder. And if responder has only one 4th major, he use an indirect Stayman (see longer).

5 4.
He must use the relay response 2 for indirect
transfer to 3 as just above, then deny the weakness
of the hand by bidding 3 or 4 :

* Obliged completing to 3.
** Game limited. The responder has 6 and closes to 4.
*** Forcing game. The opener bids his first control if he has at least
3, if not he bids 3NT.
After an eventual opener's control, the responder closes to
4. But he goes on controls by slam hope.
This auction is longer than a direct transfer response, but has the same efficiency.
He begins by bidding a relay answer in the opposite major, then after completing to 2NT by the opener, he bids an indirect Transfer request to his major suit.

**** Completing 3 by bidding his best major.
This auction means a weak but incitative hand to the game with 3/4 useful HCP.
It is a weaker auction than the direct answer 4.
The opener may complete direct to game if he is maximum, mainly with 4 cards in a major.
If the responder's hand is yet weaker, instead of answer 2NT the responder bids his best major by using indirect transfer.

Instead of the unique and classical 4NT bidding, the responder has at his disposal 4 quantitative biddings, whoose 2 real Blackwoods :

| 4NT (Blackwood) balanced and at least 14HCP |
and

* Without 5-cards minor suiter after relay 2,
and with 5-cards minor suiter after relay 2,
(therefore 13HCPL)
Theese openings are quite different from classical openings 1NT and 2NT, because
respectively replaced by 1 and
2
The opening 1NT includes all the functions of the powerful french opening
'2 multi', and
many others.
The opening 2NT is used for weak 7 cards dam openings at
,
, ,
and which are openend by transfer :
2NT (Transfer to ),
3 (Transfer to ),

But this opening includes also some strong and powerfil auctions.
