After opening 1NT many players use the Styaman respons 2 when they have a major suiter of 5 cards
and just 8HCP. And this, for one of theese 3 following reasons, to discuss and agree with partner.
Theese 3 reasons and meanings are different, and each is good. But as drawback, one must choose and agree about one meaning, one only, and forget the 2 others, when each of theese would require a specific auction.
The responder has at his disposal a specific auction for each of theese 3 different conventions.
When the opener has not the fit in responder' major suiter that does not get a big change : The contract will result
in 2 ou 2
, sometimes in 2NT. But when he has the fit, the
accurate informations supplied by responder's response enable the opener to aim at game,
even if he has not a maximum hand.
First, for players who come in this site for the first time, it is necessary to tell that, in
'majeure precisee', the opening 1 substitutes
the classical opening 1NT. Therefore the opening 1
is balanced, do not include 5 cards in any major, and includes 15-17HCP. It this the basis of our
system.

* Of course, this auction is valid also for all responder's hand including a 5 cards major suiter and at least 9HCP, with singleton or not and whith which the responder has no problem for his second bid.
* With at least 9HCP and with a singleton or not, the reponder must always use one of theese 2 above auctions.
The responder must bid 1NT as first answer, then after obliged completing
2 by opener, he bids his 5 cards major-suiter by
transfer.

* 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 color is undeterminated.
When the opener is fitted in the major but has a weakness in a color (3 weak cards), if the singleton has this same color it is as useful as gold, if not it is not useful and has nearly no interest.
Searching the color of responder's singleton
If the opener is fitted in responder's 5 cards major-suiter, he must do an interrogative bidding about the color of singleton. If not he must complete in the 5 cards major-suiter :

* What is color of your singleton
It is onvious that que biddinds 2NT by opener or responder are not natural : Each time 2NT is bidded, each player knows that the 5 cards major suiter of responder is fitted. Therefore no question to play NT. Anyhow, the opener could not bid 2NT in order to play NT, because he would not know the color of singleton.
When he knows the color of singleton the opener comes to the decision : He closes to major game if the singleton is favourable. If not, he completes in fitted major at level 3. The contract in major, no fitted at level 2 or fitted at level 3 or 4, will be always played by opener.
NB :
Theese auctions are quite different from classical biddings which begin by a Stayman
2 :
1NT | 2![]() |
2![]() |
2![]() |
2![]() ![]() |
Theese classical auctions do not precise if the 5 cards major suiter include a singleton or not, force the responder to play the contract in major, and do not allow the searching of singleton.
* The following auctions require either 7H or just 8H with a singleto, or just 8H without
singleton. If the responder has a major 54 two-suiter and at least 9HCP he must use the Stayman
answer 2 .
The rsponder use the 'impossible' following auction :

** This auction has theoretically no sense.
If the responder wanted show a weak hand with a
5 suiter
he would have used the relay 1
then
after 1NT he would have bidded 2

)..
This unusual auction is 'impossible' indeed. That
dénies the responder's weakness, and conventionally
defines 5
