How to explain the forcing NT

♠9842
♥954
♦1032
♣KQ6
Partner rebid 2♦ and I finished the weak raise with 2♥.
The opponents asked about our bidding and we explained 1NT is forcing and that this is the weakest raise (4)5-7 with 3 hearts or 6-9 with 2 hearts.
They took over with a double to end in 3♠ in a mosyian (4-3) fit, going 2 off.
At the end of the play declarer noticed my four spades and called the director.
They say we should have mentioned the fact that the weak hand with 3 hearts will not bid spades. Should we?

I agree but I bet they don't think they are being ridiculous. So education is probably the answer, this time.

Yes and lets hope they aren't so pedantic next time.

A - If yes, then your system is that weak heart raise will not bid spades.
B - If not, then your system is that weak heart raise does not bid 4-card spades if the spades are bad.
Since the opponents actually asked about the 1N(F) bid [I don't know why they asked, but they did...maybe they were novices?], the detail of your agreement should be included in the explanation, if you had an agreement A or B. It seems to me you did have an agreement, at least that is how I read the original post, last line of it. So I think you should have included it in the explanation.

But unasked, you aren't required to volunteer every single possible negative inference under the sun, they are supposed to be able to work out some of them on their own, the fact that responder can choose to conceal spades having heart support is supposed to be general bridge knowledge.
If you had to volunteer every single negative inference to the smallest detail, and cater to opponents not having any general bridge knowledge, explanations would take forever. You try to give the opponents information about any aspect of your bid that is unusual, but concealing spades to raise hearts is not unusual. If they want to know about all the normal usual negative inferences they should ask. Unprompted, you should volunteer all positive inferences, and unusual negative inferences. But if you have to teach them everything about bridge unprompted, that's just impractical.

They asked (lord knows why they asked...) about the 1NT. They didn't ask about spades - which would be an improper form of a question anyway. They phrased the question properly, I assume, asking about the 1NT bid. We are obligated to explain our agreements in full and "if" our agreement is either A or B (not repeating here what I wrote before), that needs to be included in the explanation.
If there is no agreement and bypassing spades was a judgment call with this hand, then it is a different matter, but from what OP wrote, I gather that they DID have an agreement not to bid spades with the weaker variety of heart raises (which go through a forcing 1NT). What reason is there not to include this in the explanation, particularly if (as I suspect) the opponents are intermediates or lower in level.
I am in no way in favor of explaining every negative inference, let alone volunteering unprompted. But they asked! We are obligated by law to explain the bid IN FULL.

you might bid 1♠ anyway and plan to bid 2♥ over 2m but pass 1NT.

Not everyone plays a forcing NT and to those who don't the inference that a weak raise may bypass a four-card spade suit may not be obvious. To me this is the sort of information that a response to a question should provide.

- "We play 2 of a minor as game forcing, so this may be up to a 12-count, may have 3-card heart support and might have four spades"
There is some more information available if they ask further questions (e.g. when we respond 1NT with 3-card support, when we might have four spades).
I play in a country where 5-card majors 2/1 methods are still relatively unknown amongst non-experts. The 'standard' method in this country is never to respond 1NT with four spades. Thus I think not explaining that 1NT may have four spades is misinformation, at least here.
I believe very strongly that you can not say it is 'general bridge knowledge' that 1NT may have four spades, it's a feature of your systemic agreements.
However, having said all this, while as TD I would say you should have said that 1NT may have four says, I would not necessarily adjust the score, because the lack of this information may not have caused damage.
(The short form of reply ("sem-forcing") is given to opponents whom I know, who either play the same method or certainly know it.)

Similarly, in the UK I might describe my leads as "second and fourth", knowing that this would be understood correctly; elsewhere I'd say "Fourth from an honour; second from three or more small cards." I'd also give the longer explanation if my opponents appeared to be overseas visitors or beginners.
The fact that the original poster's opponents wanted a more detailed explanation than simply "forcing" was an indication that they weren't familiar with the forcing notrump, or with using it to show a weak raise, so a more complete explanation might have been wiser. Rather than being aggrieved that they asked for a ruling, it would make more sense to note that your explanation didn't tell this pair everything that they wanted to know, and to go into a bit more detail next time.

Thx Frances.
That is a correct and compact way to explain the forcing NT.
I will adapt it.

The doubleton support is shown generally via the forcing NT. Why fool around in ♠ with a weak hand and a known 8-card fit in ♥?

Does is?
I've always played that auction as constructive with exactly 5=2 in the majors.
Not that it ever comes up....
One can also play that 1H - 1NT may have five spades if it has a limit raise with three hearts, and thus 1H- 1S - 2S - 3H is forcing. I don't do this (not least becauseI play 1NT as semi-forcing rather than forcing), but it's a quite playable method in the forcing NT.
