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.

1 | Pass (6) very weak hand |

1 ou 1 (relay to 1NT) * | |

1NT (Transfer to 2) presumed weak with 6 ** | |

2 (direct Stayman) major two-suiter 44 or 54 *** | |

2(direct transfer to ) with 5, 8HCP mini | |

2 (direct transfer to ) with 5, 8HCP mini | |

2 (transfer to ) with 6 **** | |

4(with 5 5) limited to game | |

3NT (balanced) quantitativ with 17HCP ******* | |

4NT (Blackwood) at least 18H ******* |

* The relay answer requires always the opener to complete at 1NT. The choice of the relay 1 or 1 is always very important (except for playing at NT). Please read farther why and how at "The indirect answers of responder"

** 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".

*** Please read more details in "The main auctions" at paragraph "The responder has at least and 4 cards in a major".

**** Game hope, and limited to game. Forcing to 2NT with fit, if not to 3.

***** Requires completing by opener to his better minor.

****** Slam biddings with at least 1 Ace.

******* With just 16HCP and balanced hand, the responder bids first a relay, no matter 1
or 1, then he bids 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.

An indirect answer is the second answer of the responder after a relay followed by obligatory
completing 1NT by opener, and which shows his real meaning.

The choice of the relay 1 or 1 is always very important.

1 | 1 (relay) or 1 (relay) |

1NT | Pass (at most 7HCP) balanced * |

2NT (8HCP) balanced and no major suiter * | |

3NT (at least 9H) balanced and no major suiter * | |

* By theese auctions, using relay 1 or 1 does not matter. Theese simple answers are similar as classicals, but very more accurate auctions are at disposal. Please see details at "The main auctions".

** With 4 after relay 1, and with
4 after
relay 1.

*** With at most 7HCP. The opener must complete at level 2 in the five-cards major suiter of responder.

**** Always with relay 1, never with relay 1.
Using relay 1 would show 5 with just 8HCP and a singleton.
See why in Main auctions.

***** Slam biddings. With no Ace after relay 1, and with at least 1 Ace after relay
1.

****** Slam biddings. With 1 Ace after relay 1, and with 2 Aces after relay
1. If the responder has no Ace, see his answers 3
and 3 in "Extensions".

******* See in first table the direct answers for balanced hands with 17HCP and at least 18HCP

3NT (balanced) no major, at least 9H ****** |

* Obligatory completing to 2. If the responder has a very weak hand with 6 instead of
6, after opening 1 he passes merely.

** 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. Please read :

Biidding a five-cards major of 7-8HCP by Stayman

*** 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, the responder passes if he has only 5/8H but he bids his major singleton if he has at least 9HCP.

**** From 6HCP whith a void. With at least 9HCP the responder bids the direct
response 4.

By event when the responder has 7-8HCP and 5
4 or
5 4, see
please :

The Stayman answer with 5 cards in a major and just 8HCP

***** Slam biddings with no Ace. With at least 1 Ace, see indirect answers of responder from 4
to 4.

****** Lead orientation. Responder with no major suiter, with balanced or semi 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.

The responder may use the simple auctions which are descreibt above. Therefore, after a relay answer followed by completing 1NT, he passes with at most 7HCP, bids 2NT with 8HCP, and bids 3NT with 9-10HCP. Theese answers are similar to classical but no accurate. No matter the choice of the used relay.

The responder may use more technical and accurare auctions. But it is necessary first to
read farther :

The responder has a five-cards major suiter but a weak hand

1 | 1NT (Transfer request to 2) * |

2 (completing) | Pass (with 5 or 6) distressing hand |

* The opener must complete to 2 and :

1 | Pass (with 5 or 6) distressing hand |

By conventional opening 1NT it is no possible to let play 2 which would be a Stayman bid or 2 which would be a transfer request to 2. And of course also to let play 1

1 | 2 (Transfer to or NT) |

2(with 3) 15HCP * | |

2NT(with 2) 15HCP * | |

3 (with 3) 16-17HCP | |

3NT(with 2) 16-17HCP |

* The reponder passes with just 8HCP, and :

1 | 2 (Transfer to or NT) |

2 (with 3) 15HCP * | |

2NT (with 2) 15HCP * | |

3 (with 3) 16-17HCP | |

3NT (with 2) 16-17HCP |

* The reponder passes with just 8HCP

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
to 1NT by the opener, he bids a major indirect Transfer to his major suiter.

The opener must complete the major indirect Transfer, with or without fit in responder's major.

1 | 1 (relay) |

1NT * | 2 (Transfer to 2) with 5 at most 7HCP |

2 * | Pass |

* Ccompleting relay 1

** Completing 2 with
or without fit

and :

1 | 1 (relay) |

1NT * | 2(Transfer to 2) with 5 at most 7HCP |

2 ** | Pass |

* Completing relay 1

** Completing 2 with
or without fit

* (The responder may have a four-cards major suiter but he has 7-8HCP and a very balanced hand and has better to let play to NT).

Before reading this section it is quite necessary for its understanding to read the paragraph justs above whose title is 'The responder has a five cards major suiter and 8HCP'

In order to bid and play normally a game 3NT it is necessary that the line has a minimum total either of 25 HCP without any five-cards minor suiter, or 25 lenght's HCP (25 HCPL) with a such minor suiter. If the line has only 24HCP, without any five-cards minor suiter, the game is very hasardous.

The question is, how the opener can detect if the responder has a five-cards minor suiter or not. This is all the more important as it is frequent.

After an opening 1NT the responder has only the two indefinite answers 2NT with 8-9HCP and 3NT with 10HCP. The opener has not any mean to know if the responder has a five-cards minor suiter, or not. When by playing majeure precisee, the responder has 4 accurate answers at his disposal, which show together how much HCP he has and if he has a five-cards minor suiter or not.

Of course, the opener may have himself a five-cards minor suiter what gives 1 HCPL more to his hand.

Theese accurate answers by responder are possible thanks to using the relays 1 and 1 and 1 "impossible" auction :

The responder may have 7HCP, but without five-cards minor suiter.

1 | 1 or 1 (relay) * |

1NT (completing) | Pass |

* That is the only case when no matter what relay 1 or 1 is used.

1 | 1 (relay) |

1NT (completing) * | 2NT (with 8HCP) |

The opener closes to 3NT if he has 17HCP or 17HCPL If he has less, the game is very doubtful.

1 | 1 (relay) |

1NT (compl.) * | 2 (Indirect transfer to ) maxi 8HCP |

2 (compl.) ** | 2NT (with 9HCPL) *** |

* Obliged completing the relay 1

** Obliged completing 2,
with or without fit .

*** The responder must normally pass. Therefore this 2NT is an impossible bidding which denies
5, and guarantees 8HCP with a minor five-cards minor suiter, therefore 9HCPL.

The opener must close to 3NT if he has at least 16HCP. If he has less he passes.

1 | 1 (relay) |

1NT (completing) | 2NT (with 9HCP) |

The opener most close to 3NT if he has at least 16HCP or 16HCPL. If he has less he passes.

1 | 1 (relay) |

1NT (completing) | 3NT (at least 10HCPL) * |

* Of course the opener closes also to 3NT if he has at least 10HCP, with or without a five-cards minor suiter.

__Remarks__

After the direct or indirect bidding 2NT by responder, the opener has all the necessary informations to deem if he must pass or close to 3NT. He has just a simple addition to do, in order to check if the line has at least 25HCPL or not.

After a relay 1, the responder has never more than 8HCP. But he has 9HCPL if he uses first the "impossible" answer before the bidding 2NT.

After a relay 1 completed to 1NT, if the responder bids 2NT he has just 9HCP, and if he bids 3NT he has at least 10HCPL or 10HCP.

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 major, the opener will play also the contract at NT

1 | 1 (relay) |

1NT (obliged) | 2 (Stayman) with 4 |

After 2(Stayman), the opener shows together his strenght and if he has or not 4 cards in the responder's major.

Examples :

1 | 1 (relay) |

1NT (obliged) | 2 (Stayman) with 4 and 8H+ |

2(no 4) 15-17HCP | |

2 (with 4), 15HCP * | |

3 (with 4), 16-17HCP |

* The responder passes after 2 with only 8HCP.
By classical bidding the auction would lead uselessly to 3

After the negative bidding 2 :

1 | 1 (relay) |

1NT | 2 (Stayman) with 4 and 8H+ |

2 * | 2NT (with 4) balanced and 8HCP |

3NT (with 4) balanced and 9HCP+ | |

3 (with 4 5/6) 9HCP+ and 1 singleton | |

3(with 4 5/6) 9HCP+ et 1 singleton |

* Without any major suiter

and after the relay 1 :

1 | 1 (relay) |

1NT (obliged) | 2 (Stayman) with 4, 8HCP+ |

2 (no 4), 15-17HCP | |

2 (with 4), 15HCP | |

3 (with 4), 16-17HCP |

After negative answer 2 :

1 | 1 (relay) |

1NT | 2 (Stayman) with 4 and 8HCP+ |

2 * | 2NT (with 4) balanced and 8HCP |

3NT (with 4) balanced and 9HCP+ | |

3 (with 4 5/6) 9HCP+ and 1 singleton | |

3(with 4 5/6) 9HCP+ and 1 singleton |

The responder has at least 8HCP and a 4 cards major suit, or 5 cards in a major and 4 cards in the other one

Direct Stayman 2 :

1 | 2 (5 4, 5 4, or 4 4) * |

2(no major 4°) | |

2 (with 4) * | |

2 (with 4) * | |

2NT (with 4 4) ** |

* After answer 2 the responder closes to 4, and after
answer 2 he closes to 4. But if the responder has a slam hope,
he bids his first control.

** The responder bids his major by transfer, 3 for
and 3 for . After completing by opener, the responder
closes to game in the bidded major, but bids his first control if he has a slam hope.

The answer 2 :

1 | 2 (with 5 4, 5 4, or 4 4) |

2(no major 4°) | 2 (with 4 4) and 8HCP * |

2 (with 4 4) and 9HCP * | |

3 (with 5 4) at least 9HCP ** | |

3 (with 5 4) at least 9HCP ** |

* 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
(indirect Stayman).

1 | 1NT (Transfer to ) * |

2 | Pass (with 5 or 6) and distress hand |

. | |

2 (with 5) and 7-8HCP ** | |

2 (with 5) and 7-8HCP ** |

* 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 | Pass (5 or 6) distress hand |

2 (with 5) and 7-8HCP ** | |

2 (no fitted ) * | |

2 (asking singl. ) ** | |

2NT (asking singl. ) ** | |

3 (asking singl. ) ** |

* The responder must pass.

** All theese biddings show the fit .

If the responder has not the asked singleton he must bid 3. The opener will complete to 3 and will
play 3.

If the responder has the asked singleton he must bid 4.
The opener will complete to 4 and
will play 4

and

1 | 1NT (Transfer to ) * |

2 | Pass (5 or 6) distress hand |

2 (with 5) and 7-8HCP ** | |

2 (no fitted ) * | |

2NT (asking singl. ) ** | |

3 (asking singl. ) ** | |

3 (asking singl. ) ** |

* The responder must pass.

** All theese biddings show the fit .

If the responder has not the asked singleton he must bid 3. The opener will complete
to 3 and will play 3.

If the responder has the asked singleton he must bid 4. The opener will complete
to 4 and will play 4

NB :

By this context the natural bidding 2NT by opener would not make any sense. There is no talk of playing 2NT when the color of singleton is not known.
Therefore this bidding 2NT is used as asking singleton.

After opening 1 the partner has 9HCP, whith balanced hand and whithout any major suiter. He knows that the final contract will be 3NT. Generally he
bids 1H relay, and after completing 1NT by opener, he bids 3NT

But if he has at least 2 queens, above all major queens because the probably lead will be in major, he is interested in receiving the lead and playing himself the contract 3NT.
No problem, instead of 1, he bids 1NT and after completing 2 by opener he bids 3NT. For instance with Qx Qxx KJxxx Jxx :

1 | 1NT |

2 (completing) | 3NT (with 9HCP) balanced hand * |

* Without any major suiter, with at least 2 queens.

With same hand but 1HCP less, after completing 2 by opener, the responder will bid 2NT instead of 3NT.

The quantitative biddings

Instead of the unique and classical bidding 4NT with 16-17HCP, the responder has at his disposal 3 quantitative biddings :

1 | 3NT (quantitative) 17HCP |

4NT (Blackwood) at least 18HCP |

and

1 | 1 or 1 (relay) * |

1NT (complete) | 4NT (quantitative) 16HCP |

* No matter what relay is used.

The responder has a minor 54 two-suiter with major singleton

__The 54 minor two-suiter is weak or game limited__

The responder has at least 5/6HCP he has better the contract 2 or 2 than 1NT. Or he has at least 9HCP and game hope at NT or in a minor.

1 | 1NT (Transfer to ) |

2 * | 2 (with 5 4) |

2NT(with 5 4) |

The opener must complete in the fitted minor if there is one, if not in the longer minor of responder. After completing by opener, the responder passes if have only 5/8HCP but he bids his major singleton if he has at least 9HCP.

__The 54 minor two-suiter is very strong__

1 | 1 (relay) or 1 (relay) |

1NT (compl.) | 3 (5/6 4) short in , 17HLD+ * |

The answers and auctions are nearly the same as after opening 1, but at one level above. Therefore, due to higher level, there are some differnces, for instance when the responder has 2 major suiters 54 and minor slam biddings.

* The choice of the relay is as important and for the same reasons as in case of opening 1

** The opener must complete to 3.

*** Strong suiter with slam hope

**** 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. The relay 2 excludes any interest in , and the relay 2 excludes any interest in .

* The responder'strenght depends on the relay he has bidded. PLease report to The main auctions.

After the bid 3 or 3 by opener, the responder closes to
the major game. But if he has a slam hope he bids his first control.

** Indirect transfer. At most 3HCP. The opener must complete at level 3, with or without fit,
in weak major 5° suiter of responder.

*** With 1 Ace after relay 2, and with
at least 2 Aces after relay 2. With no Ace, see indirect

If the responder had 6 instead of 6, and a very weak hand,
he would have passed after opening 2

** The weakness presumption is confirmed.

*** With at least 1 Ace, use the indirect answers 4 to 4.

The responder has a balanced hand, without five-cards major suit. Generally he has no four-cards major suit, else he would have bidded a Stayman with at least 5HCP. His strenght depends on the relay he has bidded.

2 | 2 (relay) at most 3HCP * |

2 (relay) with 4HCP ** |

* Obliged completing to 2NT by opener.

** The opener must complete to 2NT if he has 20HCP, and to 3NT if he has 21HCP.

*** If the responder has at least 5HCP, he must bid first the relay
2 then, after completing 2NT by opener he must
bid 3NT.

2 | 2NT(Transfer request to 3) * |

3 (complete) | Pass (with 5 or 6) distressing hand |

* The opener must transfer to 3 and :

2 | Pass (with 5 or 6) distressing hand |

By conventional opening 2NT it is not possible to let play 3 which would be a Stayman bid or 3 which would be a transfer request to 3. And of course also to let play 2

2 | 3 (with 5 4 or 4 4) |

3NT (with 2 and 3) | |

3 (with 4) * | |

3 (with 3 or 4 ) ** |

* Precedence over 3, even
with 4
et 3
or 4.

The responder closes to if just for game. If he has slam hope he
bids his first control.

** Denies 4. With 4 the responder would have bidded 3. With 5 the responder closes to 4 if just for game. If he has slam hope he bids his first control.

If the responder has 4 4 he makes the interrogative bidding 3 in order to know if the opener has either 3 or 4. As answer the opener bids 3NT with 3, but he bids a preempted control 4 ou 4 if he has 4 :

2 | 3 (with 5 4 or 4 4) |

3 (with 3 ou 4 ) * | 3 (with 4 4) forcing |

3NT (with 3 ) | |

4 or 4 (with 4 ) ** |

* Without 4.
With 4 the opener had to bid
3 instead of
3.

** First control. The responder closes to 4
if just for game. If he has slam hope he bids his first control.

2 | 3 (with 5 4) |

3NT (with 2 and 3) | |

3 (with 4) * | |

3 (with 3 or 4) * |

* The responder closes to game at level 4, if just for game. If he has slam hope he bids his first control.

Never use the response 3 with 4 4. It could result in a major misfit 43 and to necessity for the responder to play himself the game 3NT.

NB : A double major fit is possible. If this occurs the opener chooses the major to play, generally in the fit 44.

After the reponse 3 or 3, the opener bids 3NT in the scarce case when he has opened 2 with 2 major doubletons.

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.

2 | 2 (relay) * |

2NT | 3 (Transfer to 3) with 5 at most 3HCP ** |

and :

2 | 2 (relay) * |

2NT | 3(Transfer to 3) with 5 at most 3HCP ** |

* The opener must complete to 2NT

** Indirect transfers. The responder shows clearly that his hand is too weak for game, and asks the opener for completing in his major at lowest level.

2 | 3 (Transfer to ) with 5, 4/5HCP+ |

3 (with 3) * | |

3NT (no 3) ** |

* The responder closes to 4 for game, but bids his first control if he has a slam hope

** In spite of no fit, the responder may bid his first control if he has a strong hand with at least 6,
or for a slam at NT with only 5.

He cannot use the logical and expected answer 3 wich is yet used for the hands wiyh 5 4. At first, he bids an indirect Transfer to in order to let play 3NT or 4 by opener if he is fitted. Then after completing to 3 by opener he has 3 auctions at his disposal, each at least forcing game :

2 | 2 (relay) |

2NT (obliged) | 3 (Transfer to ) weak and 5 |

3 (compl.) * | Pass (Confirmed distress) |

4 (with 6) 4HCP mini. For game ** | |

3 (with 5) 4-5H mini. For game *** | |

3NT (5 or 6) Slam hope **** |

* Obliged completing à 3

** The responder has 6 and let play 4 by opener even if this one may have
only 2.

*** The opener completes to 4 if he is fitted, if not he bids 3NT.

**** The opener bids his first control if he has fit , if not he bids 4NT what doest not prevent
the responder from proceeding to slam.

Theese auctions are longer but as telling as the direct answer 2 (Transfer to )

Instead of the unique and classical bidding 4NT with 12-13HCP, the responder has at his disposal 3 quantitative biddings : With just 12HCP he bids a relay, no matter if 1 ou 1, then he bids 4NT after completing to 2NT by opener. And :

2 | 3NT (quantitative) 13HCP |

4NT (Blackwood) at least 14HCP |

The responder has a strong minor suiter of 6 cards and slam hope

2 | 3(strong 6 suiter. No Ace. |

4(strong 6 suiter. At least 1 Ace. |

and

2 | 2 (relay) or 2 (relay) |

2NT | 3 (with strong 6 ) suiter * |

* With no Ace after relay 2, and with at least 1 Ace after relay 2.

2 | 2 (relay) or 2 (relay) |
