If he has two major doubletons, opener uses the 1NT opening, which is suitable for any response
from responder.
But if he has one major singleton and three cards
in the other major, he cannot open with a 1NT. He then opens
with 1
with 5
4
and
with 1 with
5 4.
And if he only has 15HCP, or even 16HCP, he can't really indicate his strength, especially if he
has 5
4 because
an opening 1 followed by
2 promises at least 18HCP.
with a 54 minor two-suiter
of 15-17H and 2 doubletonsIf he has 2 major doubletons, opener opens 1.
This opening is also suitable for all normal responder responses: Responses
of at least 8HCP of 2
(Transfer 
),
2(Transfer to 
),
and 2(Stayman),
and weak relay responses 1
and ambiguous 1.
And if opener has a major singleton, he also opens
with 1 :
with a 54 minor two-suiter
of 15-17H and major singletonOpener necessarily has a singleton in one major and three cards in the other. If he had a balanced or semi-balanced hand with two major doubletons, which is excluded here, he would use all the the normal sequences expected in the event of a regular hand. (See in New jacoby transfers).
After any response from responder, opener must make an abnormal response immediately indicating both the holding of a 54 minor two-suiter and the color of his major singleton. Unless, of course, he has the fit in a 5-cards major suiter bidded by responder' transfer.

or 1If he has a balanced hand, opener is obliged to correct to 1NT. If he does not, his rebid indicates a 54 minor two-suiter and the color of his major singleton.
Responder cannot have a 5-cards major suiter and at least 8HCP, otherwise he would have made
a direct transfer, 2
(Transfer to )
or 2
(Transfer to ).
However, he may have a weak 5-cards major suiter that he was preparing to bid
by indirect transfer after normal opener's rebid 1NT in the following way :
The indirect transfers, with a weak 5-cards major suiter
Responder begins with a relay in the reverse major, then after the obligatory completing to 1NT by opener, he makes an indirect Transfer to his weak 5° major.

Responder clearly indicates that his major is too weak for game, and asks opener to complete to his major, with or without a fit. Responder's hand ranges from 0HCP to 7HCP.
If opener has a major singleton, he must refuse the completing to 1NT, making an abnormal rebid that both promises a minor two-suited 54 and indicates the color of his singleton. And in addition, depending on the case, this rebid by opener must anticipate the possession of an possible weak suited 5° major by responder, which the refusal of completing to 1NT has deprived of bidding, and which opener must bid himself.
Relay response 1
Relay 1 indicates at most 7HCP : Either responder
has a balanced hand and was preparing to pass after completing 1NT, or
he has 5 and was preparing to make an indirect

(Direct Stayman) with 9H+The bids do not differ from those where opener does not have a major singleton.
The only difference is that opener's rebid of

* Opener completes to 3 if he is fitted, and

** Opener completes to 3 if he is fitted, and
to 3NT without a fit.
NB: After a 2 response, if the contract results
in 3NT but with a opener's major singleton, it is normally secured by at least 4 cards in the other
major.
The opener should never exceed the level of
3
or 3, even if it's maximum. This is to allow
responder to make a control bid if he has slam hope.
Opener can also open 1 with a
84 minor two-suit of 15-17 HCP and a major singleton, since his hand has 3 cards in the other
major. Likewise with a 55 minor two-suiter and a major singleyon, and for the same reasons.
If opener has a minor two-suiter of 15-17 HCP with two major doubletons, he also opens
with 1, then, regardless of responder's response, he makes the same responses as with a regular
hand.
