The precised major and his new Jacoby transfers

Main principles

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 opening 1 Diamond

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.

The direct responder's answers

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 ****
 
2NT (with 5 5) *****
 
3 (strong suiter 6) 17HLD+
3 (strong suiter 6) 17HLD+
3 (strong suiter 6) 17HLD+
3 (strong suiter 6) 17HLD+
 
4(with 5 5) limited to game
 
3NT (Blackwood) 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 best minor.

****** With just 16HCP and balanced hand, the responder bids first a relay,, then he bids quantitative 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'

The indirect responder's answers

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.

* 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.

**** 3 and 3. Slam biddings. After relay 1 the responder has a singleton or void at , and after relay 1 he has a singleton or void at

NB: The responder's half balanced hands with 2 minors 54 and 2 majors doubletons are ranked and discussed as balanced hands.

***** 3 and 3. Slam biddings. After relay 1 the responder has a singleton in the bidded major, and after relay 1 the responder has a void in the bidded major.

****** 4 and 4. Slam biddings. After relay 1 the responder has a singleton in the bidded minor, and after relay 1 the responder has a void in the bidded minor.

Thees 2 auctions are more accurate than strong following classic auctions :

1 2 (Transfer to b)
2b(completing) 3 (with 5 5)

****** As complement of quantitative direct answer 3NT with 17HCP, and uf direct Blackwood 4NT with at least 18HCP.

NB : After any strong two-minor suiter 54 55 or 64 bidded by responder, the Blackwood is in exclusion of the singleton's or void's color

* 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

*** 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. Presumed with just 5/6 game incitative HCP, but weaker as the direct answer 4. The opener must complete to his best major, at level 3 or 4 according to his strenght.

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.

***** 3 and 3b. Slam biddings, but with no Ace

****** 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.

NB: Please see more details at following chapter.

The main auctions

The contracts at NT

Basic Bidding in NT:

1 1 (relay) or 1 (relay)
1NT(complete) * Pass (at most 7H) balanced
2NT (with 8HCP) balanced **
3NT (at least 9HCP) balanced **

* Oblifed completing
** Without any major suiter

This sequence is the equivalent of a classic auction. When using it, the choice of 1C or 1P 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.

For clarity and brevity, the following conventions will be adopted in the following brief presentation:

- Instead of HCP points we refer to H points (Honnor points) for any hand without a 5° minor, and instead of HCPL points we refer to HL points (Honnor points more 1 length point) for any hand with a 5° minor.

- Any number of HL points indicated has the same value as the same number of H points indicated.
For example, 8HL counts as much as 8H, but only contains 7H more 1 length point.

Analysis of responder's responses and opener's rebids:

1 - Responder has at most 7H or 7HL : Responder use relay 1 then Passes after opener's 1NT completing

2 - Responder has at least 8H or 8 HL : Responder uses relay 1. Opener completes to 1NT with 15H, but to 2NT with 16H or 16HL, and to 3NT with 17H or 17HL.
Over 2NT, responder passes with at most 8H or 8HL, but bids 3NT with at least 9H or 9HL.

3 - Responder has at least 9H or 9HL : Responder also uses the relay 1.
Opener completes to 1NT, 2NT or 3NT as above. Over 1NT responder passes with at most 9H or 9HL and bids 3NT with at least 10H or 10HL.
Over 2NT responder bids 3NT

In summary, it's very simple:

Responder always uses relay 1 with at most 7H or 7HL, and relay 1P with at least 8H or 8HL.
After relay 1, opener always completes to 1NT and responder passes
After relay 1, opener always completes to 1NT with 15H, to 2NT with 16H or 16HL, and to 3NT with 17H or 17 HL.

In all cases, both responder and opener only have to make a simple addition to check whether the total in the line reaches at least 25 H or HL, or whether to stand at 1NT or 2NT, as the case may be.

The responder has a very weak hand but with 5/6 or 5/6

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

The responder has a five cards major suiter and 8HCP

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

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

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

The responder has a 54 major two suiter and just 8HCP

He makes an 'impossible' bid using the previous weak indirect major transfer auctions, just above, but replacing responder's final Paswith the 2NT response:

1 1 (relay)
1NT (compl. 1 ) 2 (Transfer to ) 5) at most 7HCP *
2 (compl. 2) 2NT **

* Obliged completing to 2
** Impossible' bid that denies the holding of a weak major unicolor suiter. By convention it indicates a 5 4 two suiter, with strictly 8HCP.

After this 2NT from responder, opener bids his fitted major if he has one, at the level 3 or 4 depending on his strength and the quality of his fit.
If he has no major fit, the opener passes or bids 3NT according to his strength.

and

1 1 (relay)
1NT (compl. 1) 2 (Transfer to ) 5 at most 7H *
2 (copl. 2) 2NT **

* Obliged completing to 2
** 'Impossible' bid which denies the holding of a weak major unicolor suiter à . By convention it indicates a 5 4 two suiter, with strictly 8HCP.

Sur ce 2SA du répondant l'ouvreur nomme sa majeure fittée s'il en a une, au palier de 3 ou de 4 selonn sa force et la qualité de son fit.
S'il n'a pas de fit majeur l'ouvreur passe ou dit 3SA selon sa force.

After this 2NT from responder, opener bids his fitted major if he has one, at the level 3 or 4 depending on his strength and the quality of his fit.
If he has no major fit, the opener passes or bids 3NT according to his strength.

The responder has at least 8HCP and 4 cards in a major

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 suiter, 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).

The responder has a five-cards major suiter with 7-8HCP and a singleton.

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) weak
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) weak
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.

The responder has a six-cards minor suiter and game hope

This auction shows a game incitative hand whith 5/6 useful HCP, weaker as the direct answer 4.
The opener completes to his best major at level 3, and at level 4 if he has a maxi hand, mainly with fit of 4 cards.

The responder must not use this auction with less than 5/6HCP.

The responder is short in a major and cannot show if this major is a singleton or a void. But he can precise the color of this singleton or void : After relais 1, its color is , and after relay 1, its color is

The opener bids his best minor at level 4, then the responder bids an excluding Blackwood by bidding the color of his sigleton or void, 4 ou 4

This BW excludes the color of singleton or void


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

1 1NT (Transfer to )
2 * 2 (with 5 4)
2NT (with 5 4)

Ambiguous. The responder is short in a major and can neither show if this major is a singleton or a void. nor precise the color of this singleton or void.
The opener must complete at level 3 in his better minor.

The 54 minor two-suiter is weak (5-7HCP)

The responder passes after completing by opener. He has better to play a contract 3 or 3 than 1NT.

The 54 minor two-suiter is game forcing.

The responder has at least 8-9HCP, with a singleton or void in a major. He bids this major. After 3 ou 3 the opener bids 3NT if he has a strong guard in this major, if not he rebids his minor.

1 1NT (Transfer to )
2 2 (with 5 4)
3(best minor) 3 (short at ) *
3NT * Pass **

* By this example the opener has a strong guard at . If not he would have make a rebid at 4 or 5 according to his strenght and his fit's quality.

** Contract acceptance. Trusting partner.

The 54 minor two-suiter is strong

The responder has at least 16HCPD (lenght and distribution). After 3NT or 4 he bids an exclusion Blackwood excluding the singleton's or void's color, by bidding it at level 4. By this example he bids 4.

This third occurence is inusual but possible. The opposite team would and could have Ace and King in case of an eventual contract 6NT : Better would be to play 6.

The responder has a strong 6-cards suiter with slam hope

He bids a strong direct answer 3, 3, 3 ou 3,

The opener has a minor 54 two-suiter and 15-17HCP

The opener has neeither major singleton nor void. He opens 1, then after any responder's answer, he bids his longer minor

Lead orientation in order to play the contract 3NT

1 1NT (Transfer to )
2 3SA

The responder has a balanced hand with neither 4 cards major suiter nor 5 cards minor suiter and 9-10HCP. He has queens or kings but no Ace. He feels that better is to play himself in order to receive the lead.

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

1 3NT (Blackwood) balanced and 13HCP
4NT (Blackwood) balanced and at least 14HCP

and

1 1 or 1 (relay)
2NT 4NT (quantitative) balanced and 12HCP *

* Without 5-cards minor suiter after relay 1, and with 5-cards minor suiter after relay 1

The opening 2 Diamonds

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 direct answers of responder

2 Pass( 5 or 6) very weak hand
  2 or 2 (relay to 2NT) *
   
  2NT (Texas ) presumed very weak with 6 **
   
3 (with 5 4 or 4 4) game forcing **
   
3 (with 5 4) game forcing **
   
  3 (direct transfer to ) with 5) game forcing
   
  3 (transfer to ) with 6 ***
   
  4(5 5) limited to game
   
  3NT (balanced) quantitativ, 13HCP ****
  4NT (Blackwood) at least 14HCP ****

* 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.
*** With at least 5/6HCP. Forcing game
**** 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 indirect answers of responder

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 .

2 2 (relay) or 2 (relay)
2NT Pass (balanced) weak *
  3NT (balanced) 5H, no major suiter *
   
  3 (Stayman) single major 4° suiter, 4/5HCP+
   
  3 (Transfer to ) when relay 2 weak with 5 **
  3(Transfer to ) when relay 2 weak with 5 **
   
  3(transfer to ) strong suiter 6 ***
   
  4 (with 5 5) short at , and 13HCPD+ ****
  4 (with 5 5) short at , and 13HLD+ ****
   
4NT (balanced) 12HCP *****

* 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.

*** Game forcing

**** 4 and 4. With singleton or void after relay 2, and with singleton or void after relay 2.

***** Complement of the direct quantitativ biddings 3NT and 4NT.

Extensions of the opening 2 Diamonds

2 2NT (transfer to 3) very weak with 5 or 6 *
3 Pass (5 or 6) very weak **
   
3 (with 5 5) weak ***
   
  3 (with 5 5) 13HLD+, short at ****
  3 (with 5 5) 13HLD+, short at ****

* Presumed very weak hand. The opener must complete to 3. 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.

*** Weak hand but game incitative hand with just 3/4 useful HCP.

**** With singleton or void.

The main auctions

The responder has a very weak hand but with 5/6 or 5/6

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

The responder has 5 4 or 4 4, forcing game

2 3 (Stayman) 5 4 or 4 4
3 (with 3 and 2/3)
3 (with 4) *
3 (with 4) *
3NT (with 2 3) **

* The responder closes to game. But with slam hope he bids his first control 4 or 4.
If the opener has 4 4 he bids 3 in order to play with fit 44 rather than 54.

** Or 2 2

After 3 :

2 3 (Stayman) 5 4 or 4 4
3 (with 3 2/3) 3 (Transfer to ) with 5 4 *
3(Transfer to NT) with 4 4 **

* The opener completes to 3. After completing to 3 the responder closes to game. But if he has a slam hope, he bids his first control.
If opener has 3 and 4, he must of course bid 3 insteed of 3
** The opener completes to 3NT.

The responder has 5 4, forcing game

For 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).

2 3 (Stayman) with 5 4
3 (with 3/4) *
3 (with 4) *
3NT (with 2 3)

* The responder closes to game in the fitted major. But if he has a slam hope he bids his first control.
If the responder has only a 4 cards major suiter, he uses an indirect Stamnan (see longer).

The indirect Stayman

Responder has only a major 4th suiter. The first response relay 2 then clearly indicates 4 without 4 and the second response indicates 4 without 4 :

2 2 (relay)
2NT (obliged) 3 (Stayman) with 4. Game forcing
3 (with 4)
3NT (without 4)

and

2 2 (relay)
2NT (obliged) 3 (Stayman) with 4
3 (with 4 )
3NT (withot 4 )

The responder has 5 without 4, forcing game

2 3 (Transfer to ) with 5
3 (with 3/4) *
3NT (without 3) **

* The responder closes to 4. But with slam hope he bids his first control 4 or 4.

The responder has 5 without 4 forcing game

He cannot use the response 3 which is used to describe 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 :

2 2 (relay)
2NT (obliged) 3 (Transfer to ) presumed weak and 5
3 (compl.) * Pass (confirmed weakness)
   
4 (with 5/6) at least 4/5HCP **
3 (with 5) forcing game ***

* 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.

The responder has a five cards major suiter, but a very weak hand

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.

The responder has a 5 5 major two-suiter

The 55 major two-suiter is weak

2 2NT (Transf. to ) with 6 *
3 (compl. 2NT) ** 3 (5 5) weak
3 or 3 (compl. 3) *** Pass (with 3/4HCP)

* Transfer to 3. Presumed weak with 6.
** Completing 2NT
*** Completing 3 by bidding his best major. This auction means a weak hand but incitative to the game with 3/4 useful HCP. It is a weaker auction than the direct answer 4. The opener may complete to the 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.

The 55 major two-suiter is game limited

2 4 (5 5) game limited

The 55 major two-suiter is strong

Strong slam auctions

2 3 (Transfer to )
3(completing) 3 (with 5 5) slam

Limit slam auctions

2 3 (Transfer to )
3(completing) 4 (with 5 5) limit slam

* Theese classical auctions may be used, but much better is to use the strong following auctions :

2 2 or 2 (relay) *
2NT 4 (with 5 5) strong, short at *
4 (with 5 5) strong, short at *

* With singleton in bidded minor after relay 2, and with void in bidded minor after relay 2. The opener bids his best major, then the responder bids an excluding Blackwood which excludes the color of the bidded minor, by rebidding this minor

The responder has a strong minor two suiter 64 and slam hope

2 2 (relay) or 2 (relay)
2NT 4 (with 6 4) strong *
  4 (with 6 4 ) strong *

* With singleton or void after relay 2, and with singleton or void after relay 2.

The responder has a strong minor two suiter 55 and slam hope

2 2NT (presumed very weak with 6)
3 (completing) 3 (with 5 5) strong *
  3 (with 5 5) strong *

* With singleton or void.

The quantitative biddings

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

2 3NT (Blackwood) balanced and 13HCP
4NT (Blackwood) balanced and at least 14HCP

and

2 2 or 2P (relay)
2NT 4NT (quantitative) balanced and 12HCP *

* Without 5-cards minor suiter after relay 2, and with 5-cards minor suiter after relay 2, (therefore 13HCPL)

The openings 1NT and 2NT

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 ), 3 (Transfer to ), et 3 (Transfer to ). But this opening includes also some strong and powerfil auctions.
