1NT opening bid: 14-16 hcp

I like the 14-16 range for 1NT. I will open it with a five card major, and with 5-4-2-2 as long as not both majors. I frequently down grade 14 point hands that are 4333 or 4432 with flaws. It is the very rare hand with 16hcp that is upgraded as being too good. I am not adverse to opening 1NT with a singleton, There are some hands with a singleton that I will open 1NT, but only when I am really worried about my rebid if I don't.

I will play about any system over 1NT, but below is my preferences taken mostly ETM victory pages (link on the side of these post).

Four level responses to 1NT opening

4♣ -> transfer to 4 responder in control
4 -> transfer to 4♠ responder in control
4/4♠ to play
4NT -> Quantitative balanced slam try. Opener accepts by showing ACES (responder signs off in 5NT immediately if two aces are missing).

Three level Responses to 1NT

3♣ -> Game force, minor two suiter (at least 5-4).
3 -> puppet stayman, looking for FIVE card major
3/3♠ --> singleton in bid major, 4 in other, GF.
3NT is to play, 4OM or 4m shows that opener thinks best spot is that suit with four of the minor , 3S/3H or 4S/3S shows slam interest in OM
3NT -> To play

Continuations 1NT-3♣
-> 3M to show weakness in OTHER major,
-> 3NT to suggest spot, and
-> 3 to find out about responders distribution.

Continuations over 1NT-3♣-3 are:

-> 3 short , (3♠ ask dist: 3NT = 3 ♠; 4 ♣; = 5[5 minors)
-> 3♠ 5-5 in minors, short ♠
-> 3NT; three hearts short spade, 1345 or 1345
-> 4♣ 1-1 in majors, 6♣
-> 4 1-1 in majors, 6
-> 4M void and 66 or 75 in the minors

Continuations over 1NT-3 puppet stayman

With a five card major, opener rebids it at the three level. Otherwise he bids 3NT. Over 3NT, Responders 4♣ is always Gerber (asking for aces , 4 showing none, 4 1, etc), and over 3M 4 is RKCB for the major suit shown.

Openers Continuations over 1NT-3M

---->3NT is to play,
---->4 Other Major to play
---->4 minor sets trumps
---->3♠ over 3 = slam try in spades
---->4♠ over 3♠ = slam try in hearts

Two Level Responses to 1NT

2♣ -> stayman, does not promise a major
2 -> transfer to 2 denies DOES NOT PROMISE HEARTS (can be balance game try)
2 transfer to 2 ♠; denies 4+ (use stayman)
2♠ transfer to 3♣ OR A RANGE checkback.
2NT -> transfer to 3 or weak minor two suiter

Continution after 1NT-2NT
Opener rebids 3 if he likes diamonds (super accepts), and bids 3♣ if not. If opener bids 3 ♣ responder with weak minor two suiter passes. If Responder has weak diamond one suiter he corrects to 3.

Continuation after 1NT - 2♠
Opener rebids 2NT with 14 or bad 15 hcp, and bids 3♣ with good 15 or more hcp. Over both pass and 2NT by opener, pass and 3 ♣ are signoffs. If responder bids a new suit, he is showing values in bid suit.

Continuation after 1NT - 2 ;-2♠ (opener must bids 2♠)

-----> pass, to play
-----> 2NT, game invite with 5 spades
-----> 3♣: GF Diamond Transfer to s
-----> 3: GF Transfer
-----> 3: Transfer to ♠s, 6+♠s, GI or better, treat as GI first
-----> 3♠: exactly 5♠s, game going or better, suit oriented
-----> 3NT: 5♠s, game going, balanced choice of games
-----> 4♣,4,4: slam try, 6+♠s. self splinter
-----> 4♠: To play.
-----> 4NT: RKCB for ♠’s.

Openers rebid after 1NT - 2

Unlike the 2 transfer, 2 does not promise even four hearts. Opener with less than four hearts bids 2 With four or more hearts, opener rebids as follows:
-----> 2 less than 4
-----> 2♠ opener has five but minimum (3 retransfer)
-----> 2NT openre has 4 minimum (3 retransfer)
-----> 3♣ opener has 5 maximum (3 retransfer)
-----> 3 opener has 4 max.

Continuation after 1NT - 2 - 2

Responder doesn't have to have hearts. e can also be balanced 3NT game try.
-----> Pass - To play
-----> 2♠ - GI with 5s or CLUB Transfer GF with 5+s & ♣s (see Green below)
-----> 2NT - GI without 5s, can have 4s but maybe not
-----> 3♣ - GF Diamond Transfer, 5+s + s.
-----> 3 - Transfer, can be Game Invite or stronger with 6+s.
-----> 3 5s, GF, first offers choice of game for opener.
------------->Opener’s bids 3♠ asking for 3NT with 5-3-3-2 or 5-4-2-2
------------->3NT/4 to play
-----> 4♣/4:singleton or void in suit bid, 6+s, slam try.
-----> 3NT: To play, usually without 5s.
-----> 4: To play.
-----> 4NT: RKCB for s.

Continuations after 1NT–2-2-2♠

Opener bids as follows:
-----> 2NT: wants to play in 2NT opposite GI with 5s.
-----> 3♣: maximum with 2’s.
-----> 3: maximum with 3’s.
-----> 3: wants to play in 3 opposite GI in s.

Then opposite all these bids, responder can bid:
-----> 3NT or 4s to play.
-----> 4NT as RKCB for s.
-----> 3♠ or 4 show singleton/voids in the suit bid and s; ♣s.
-----> 3 to show s & ♣s and no other good bid.
-----> 4♣ to show s & ♣s, at least a good 5-5.
-----> 3m (if possible) to show a GI with s & five card suit.

Continuations after 1NT–2-2♠ or higher

Responder rebids 3D to retransfer to hearts, bids 3C (if available) to ask for game with "useful minimum". Or responder can place contract with 2NT, 3NT, 3H, 4H. All other bids show hearts, jump to 4C/4D show second suit (so 6 keycard blackwood then enforced).

ETM Modified Stayman
Opener must rebid 2, 2, 2♠ or 2NT (2NT with both majors and minimum 1NT). The follow up after each of these bids are:

Continuation after 1NT-2♣-2

-----> 2 = Both majors, up to game invite strength. Opener passes with 3’s and min, bids 2♠ with 3♠’s, and bids 2NT with 3, 2♠ and max
-----> 2♠ = range check with GI, or transfer to clubs
-----> 2NT = 5+♠s, GI, may have 5+m or 4’s
-----> 3♣ = transfer to 3
-----> 3 Singleton/void in a minor, 4/5 in other minor and majors 4-4/4-3/3-4
------------->3 asks:
------------------->3♠: Club splinter
------------------->3NT: splinter, no slam interest unless it is working
------------------->4♣: 5♣s, singleton/void in s, slam interest.
------------------->4: 4-4-1-4 exactly, slam interest.
-----> 3: Transfer with 5+♠s, GF, usually 4s or 5-5 in majors, modest suits.
------------------->3♠ asks hand type:
------------------------->3NT: 4&5♠s
------------------------->4: 5-5 in the majors
------------------------->4m: cuebids with 5+♠s, 4s and slam interest.
------------------------->4♠: 6+♠, mild slam interest.
-----> 3♠: 5+s, 4♠s. Yf 6+s has slam interest (otherwise bid 4 Delayed Texas)
-----> 3NT: To play
-----> 4♣: Gerber.
-----> 4/4: Delayed Texas transfer to 4/♠.

Continuation after 1NT-2♣-2

Two hearts showed 4/5 hearts, less than 4♠
-----> 2♠ = range check with GI, or transfer to clubs
-----> 2NT = 5+♠s, GI, to invite in NT use Range ask
-----> 3♣ = transfer to 3
-----> 3 = 3’s, 4♠’s and a minor suit singleton, GF
------------>3 singleton?
---------------------->3♠ = ♣’s
---------------------->3N = ’s
-----> 3= Game invite with 4’s
-----> 3♠ = 4’s, game pick with 3-4-3-3 or slam try with no singleton/void.
-----> 3NT, 4 = To play.
-----> 4♣;4: Singleton or void, four card heart support, slam try.
-----> 4NT: RKCB for hearts.

Continuation after 1NT-2♣-2♠ (four+ spade, may have 4+s but only with max)

-----> 2NT = Club Transfer to clubs, or info seek.
-----> 3♣ = Transfer to s.
-----> 3 = 3♠s & 4s & a minor suit singleton,
-------------> 3 asks for minor suit singleton,
---------------------> 3♠ shows singleton ♣
---------------------> 3N shows singleton .
-----> 3 = 4♠s, choice of game with 4-3-3-3 or slam try without singleton/void.
-----> 3♠ = Game invite with 4♠s
-----> 4♣, 4, 4 all = splinter with spade support, slam try.
-----> 3NT: Exactly 3♠s & 4s, offers choice between 3NT, 4 and 4♠. With 4s and 2♠s use 2 asking bid or use 1NT-2♣-2♠-2NT-3♣-3 ask sequence.

Continuations for Range Ask
Three sequences are used investigate opener’s shape. Two of them first find out if opener is minimum or maximum, but there is no range ask available over the 2♠ bid.

1NT-2♣-2-2♠(range asks)-2NT (min) or
1NT-2♣-2-2♠(range asks)-3♣ (max), in both cases, 3 re-asks:

-----> 3 = 4+♣s, can have 4s.
------------> 3♠ asks for 4s? 3NT is no.
-----> 3♠ = 5+s, not 4♣s
-----> 3NT: 3-3-4-3 or 3-3-3-4

1NT-2♣-2-2-2♠(range asks)-2NT or 3♣ (in both cases)-3 re-asks:

-----> 3 = 4+♣s or 3-4-3-3. 3♠ asks if 4+♣s, 3NT is no.
-----> 3♠ = 4+s.
-----> 3NT = 5s.

1NT-2♣-2♠-2NT-3♣-3 (asks):

-----> 3 = 4+♣s or 4-3-3-3.
------------> 3♠ asks if 4+♣s, 3NT is no.
-----> 3♠ = 4+s.
-----> 3NT = 5♠s.

After these bids, 4m is RKCB for that minor suit if both minors are available: if only 4 is available it is RKCB the minor opener last showed. 4NT is slam invitational, not-forcing. If opener has shown one major (and denied the other), the other major is RKCB for the major suit. Responder can choose to use RKCB in one suit, and then later correct to a different suit at the slam level, using RKCB to find out the holding in a suit.

A lot of this is "standard" so I will instead show some funky auctions in the examples below.

Some comments:

What is 1NT-2H-2S-3D?
Does 1NT-2H-2S-4S still show mild slam interest?
Why can 1NT-2D be a balanced game try while 1NT-2S already includes the range check (can pass 2NT with minimum)?

The reason 1NT-2D- can be balanced hand is that it checks for both 4 and 5 card heart suits on the way to 2NT. So if responder has a 4 card heart suit, he finds a fit, or if he has three card heart suit, he might well find a 5-3 fit.

2S on the other hand, give you the option of playing in 3 CLUBS when weak as well as the game try when heart legnth is not an issue.

1NT-2H-2S-3C is transfer to 3D, and (tada), 1NT-2H-2S-3D is transfer (well shows) diamonds. Both 3C and 3D here are game force

1NT-2H-2S-4S is essentially devoid of slam interest now, because you can use the checkback. But it must have shown some interest to start off with, so opener with a superduper max and fit, might try something.
