I never open NT with 5 card major, so this is irrelevant to me.
I open all 5-3-3-2 majors and most 5-3-3-2 minors a suit. The only case that I open NT with 5-3-3-2 shape is 1NT with garbage 5-card minors, with the 5
♣s, I will even be more cautious in opening 1NT because there is the possibility that responder bids 2
♣ and run into a 4-2
♦s (4=4=4=1 over 3=3=2=5) (This may be solved by crawling Stayman, but the usage of 1NT-2
♣-2
♦-2
♥ as invitational to find a 5-3 fit in
♥s with 5
♥s and 4
♠s will be lost).
I think that the following responses to 1NT may be used to find
all major suit fits with at least invitational values when 1NT does not include 5-card majors:
4
♥s only: bid 2
♣, raise
♥ but correct back to 2NT with other responses.
4
♠s only: bid 2
♣, raise
♠. Correct back to 2NT over 2
♦, bid 2
♠ over 2
♥. Opener will raise it holding 4-4 in the majors but correct to 2NT if no 4
♠s.
5 cards in one major only: transfer to it directly then bid 2NT as a choice bid.
4 cards in both majors: bid 2
♣, raise any majors, correct back to 2NT over 2
♦.
5 cards in both majors: transfer to 2
♠ and bid 3
♥. A fit is guaranteed in this case so the loss of 2NT is not a problem.
4
♥s and 5
♠s: bid 2
♣, raise any majors, bid 2
♠ over 2
♦.
5
♥s and 4
♠s: transfer to 2
♥ and bid 2
♠.
Then there are still takeouts possible with busts in both majors:
bid 2
♣, pass any majors and bid 2
♥ over 2
♦. Opener corrects to his 3-card major.
I play 4-suit transfers so the contract can be escaped to 3 of a minor with a minor bust.
To summarise, the whole set of major suit responses is as follows:
1NT (15-17 balanced, no 5-card major)
- 2
♣ - Stayman - promises a 4-card major, any rebid except 2
♥ promises invitational values and force to either 2NT or 3 of a major.
-- 2
♦ - no 4-card major
--- 2
♥ - weak takeout, opener correct to his 3-card major
--- 2
♠ - exactly 5
♠s and 4
♥s, F1, raise or correct
--- 2/3NT - no major fit
-- 2
♥ - 4
♥s, may have 4
♠s
--- 2
♠ - no 4
♥s, exactly 4
♠s, F1, raise or correct
--- 2/3NT - no major fit
-- 2
♠ - 4
♠s, no 4
♥s
--- 2/3NT - no major fit
- 2
♦ - transfer to 2
♥, 5+
♥s
-- 2
♥
--- 2
♠ - exactly 5
♥s and 4
♠s, F1
--- 2/3NT - pass or raise with exactly 2
♥s, otherwise, correct it
--- 3/4
♥ - 6+
♥s
- 2
♥ - transfer to 2
♠, 5+
♠s
-- 2
♠
--- 2/3NT - pass or raise with exactly 2
♠s, otherwise, correct it
--- 3
♥ - exactly 5
♥s and 5
♠s: pass, raise or correct.
--- 3/4
♠ - 6+
♠s
The above system works over 2NT also, but the responder is now game-forcing rather than invitational of course. Weak takeouts are still possible. With puppet Stayman, all weak takeouts are gone.
The above is all messed up once you include 5-card majors in your 1NT opening. When opening 5-3-3-2 majors with 1 of a suit, any 5-3 fit is guaranteed to be found since it is a simple raise only. 6-2 fit can also be found by bidding the major twice.
At IMPs, you shouldn't be thinking when both 3NT and 4M is making. Just choose one at your convenience. The case when 3NT makes but 4M not is rare when a fit exists, but 4M makes when 3NT not due to a lack of stoppers is common. Therefore, always play in a major when a fit can be found, 3NT should be used only as a last resort.
Having the opportunity of weak takeouts is
essential. You don't want the opponents running your 2-card suit in a 1NT contract and get -3 when actually a 2-level suit contract can be made (with a 8-card fit) or -1 only (with a 7-card fit).

In
this thread, Rainer Herrmann asked, Minors over 2NT: Do you have good agreements?
If you still haven’t been convinced to dump Puppet Stayman, the post below has been copied in from the above thread.
Minors Over 2NT: Do you have good agreements?
Rainer Herrmann:
This thread of yours appears to have stumped the panel of posters. I have no idea if this has happened before. A handful of people have offered a bidding sequence for the actual hand posted. Thus far, no one has offered a TOTAL GOOD AGREEMENT as suggested in the thread title.
My own bidding agreements over 2NT have a much greater focus on the majors. I’m guessing that other regular posters are guilty of the same error as myself. You have opened up a hole in my bidding structures which I am diligently working on to plug.
What are my objectives over 2NT? I still want to be able to retain as many as possible of the following:
1. Stayman / Garbage Stayman / Crawling Stayman
2. Jacoby Transfer Bids
3. Smolen (both 5/4 and 6/4 holdings)
4. Minor Suit Stayman / 4-Way transfer bids. As I cannot have both, once I have managed to plug the hole in my bidding agreements, it will become evident which one gets dumped.
5. The ability to show 5/5 in the minors with no slam interest
6. The ability to show 5/5 in the minors with slam interest
7. The ability to sign off in 4 of a minor with a minor suit bust
8. The ability to transfer into a minor suit single suiter and then continue with slam exploration with the appropriate hand
9. Texas / SA Texas in my current agreements will need to go to make room for 5-8 above. This will be accommodated via Jacoby Transfer Bids followed by a raise to game. I still need to decide exactly what I will use the 4♣ and 4♦ bids for now.
10. Gerber has long ago been dumped in favour of a quantitative 4NT
I am already facing some creative thinking to restructure my current agreements to accommodate all of the above. I am now asking this for the third time; how do you also include Puppet Stayman in amongst a very scarce resource i.e. available bidding space? To complicate this jigsaw puzzle even further; I need to be able to cope with opposition interference.
1. OK
2. OK
3. Just exchange meaning of the above 2NT-3
♣-3
♦-3
♠ and 2NT-3
♣-3
♦-4
♥ (since 3
♥ is taken as crawling Stayman) to use Smolen transfer and its OK. With a 6-card suit, always Jacoby transfer to it directly since a fit is guaranteed.
4. 2NT-3
♠ can be used as MSS
5. Just copy the above Stayman system
6. Just copy the above Stayman system
7. bid it directly
8. use 4
♥ and 4
♠ as transfers to the minors respectively
The complete 2NT system above:
2NT (20-21 balanced, no 5-card major)
- 3
♣ - Stayman - promises a 4-card major, any rebid except 3
♥ forces to major/NT game. (There is no need to use Smolen on 6/4 holdings since a fit is guaranteed.)
-- 3
♦ - no 4-card major
--- 3
♥ - weak takeout, opener correct to his 3-card major
--- 3
♠ - exactly 4
♠s and 5
♥s, Smolen transfer, accept or reject.
--- 3NT - no major fit
--- 4
♥ - exactly 5
♠s and 4

--- 4NT - quantitative slam interest - no minor fit
--- 5
♣ - 5-5 in the minors, pick one, no slam interest
-- 4
♣/4
♦ - confirms a fit, bid game or use 4
♥/
♠ as some sort of slam try (e.g. Kickback)
- 3NT -
STOP
- 4
♣/
♦ - minor bust sign-off
- 4
♥/
♠ - 6+ card transfers into
♣ or
♦ respectively. Opener must bid game. Responder may then bid slam.
- 4NT - quantitative
Enough?!
