I really dont know if nmf is one or there are some ways to play it, and what is considered standar.

Opening 1 minor, we have i.e 1♣ 1♥ 1N 2♦

Priorities are:

1º way says,

1º Show 3 card support, 2H-3H min-max
2º Show the other major 4º 2S-3S min-max
3º 2NT-3N min-max

This way, you miss a 44 fit to play game, but is safe when you also have 3 card support to play 2H.

2º way says,

1º Show the other 4º card major, 2S-3S min-max
2º Show 3 card suppor, 2H-3H min max
3º 2NT-3NT min-max

You do not miss 44 major fit this way, but with minimun, you may be in the wrong contract, or not?

1♣ 1♥
1n 2♦
2♠ ?¿ 2N if not 4 spades when you should be playing 2H.?


3º way, I'm sure i read it anywhere, but

If max: Show the other 4º card major before 3 card support.
You are committed to game, if p has no support, he will bid 3n and then you can bid 4 in his major.

If min, show 3 card support to your p's major.




Opening 1♥ 1♠ 1N

What is here available about this stuff?

Bid your stronger minor? use the minor as any kind of two-ways?

Bidding your stronger minor, what are opener priorities?

1º Show 3 card suppor, min-max
2º Show 4º card minor support rather than NT?

ty all,

Hi,

there is probbaly no simple answer,
but ask yourself, what responder
interest most?

Looking at the auction

1C - 1H
1NT - 2D

Opener denied a 4 card spade suit (*),
i.e. responder is looking for 3 card
heart support and not for the magic
4-3 fit.

The 2nd priority is strength.

The 3rd priority a 4 card side suit.

Looking at

1H - 1S
1N - 2C

Most of the time, opener will be 5-3-3-2, i.e
support comes first, after that stoppers in the
minors (min / max), and a distant 3rd is
a 4 card minor, which usually does not exist
anyway, espesially if you bid out your shape.

Keep life simple.

With kind regards
Marlowe

(*) You may disagree, but if opener bids
1NT with 4-3-3-3, he decided, that he had
no interest in spade, and that is fine,
... catering for those rare cases when spades
may play better, makes bidding a nightmare.

You might consider playing 2-way NMF:

After 1x-1y-1NT:

2♣: relay to 2♦ to show an invitational hand or to signoff in 2♦
2♦: artificial game force
3♣: signoff

Other bids generally mean what they would have meant before.

NMF is fine for choice-of-game auctions but can be confusing in slam auctions due to "what-is-forcing" and "how-much-have-I-shown" questions.

I play 2-way NMF by unpassed hands only, and find it to be more effective and simpler than regular NMF.

1) Most play that in the auction 1C 1S 1N 2D, opener's first responsibility is to show 4h, 2nd responsibility is 3s. If neither, then 2N with min, 3N with max.
2) Since most play that 1C 1S 1N 3C is invitational, another use of NMF is for a minor suit GF raise. So jumping with max and support may not be wise as it crowds the auction when responder wants to raise opener's minor. Responder can always raise from 2 to 3 with an invitational hand.
3) Many play that 1C 1H 1N, opener is denying 4s. If you play that, too, then after 1C 1H 1N 2D, opener can use the "impossible 2S" bid to show a max first before answering the 3-card heart support question.

[Winstonm]

How you play NMF depends on how you define responder's hand. The standard is that it is invitational values. Therefore, typical responses are.

2M=3 card support minimum
2N=2 card support minimum
3M=3 card support maximum
3N=2 card support maximum
2H=4 hearts, 2 spades, minimum
3H=4 hearts, 2/3 spades, maximum

Yes, I disagree. I will often rebid 1NT with that shape, and I have no problem recommending it to anyone who plays NMF. Bidding NT whenever you have an excuse is a good idea because it immediately limits your hand, which is very useful information to partner. The only problem with it is that you may play 1NT when 2♠ might have been better. But the same thing happens if responder bids 1♠ with 5 ♠, 4 ♥ and a minimum -- there's no way to get to 2♥, and we live with that.

Since games usually play better in 4-4 fits than 5-3 fits, I'd like to find the ♠ fit. So I like the precedence to be showing 4 cards in the other major, then 3 cards in responder's major.

However, I believe the most popular style is to play that opener gives the cheapest useful rebid. If responder's first bid was 1♥, opener shows ♥ support before showing a ♠ suit that was bypassed. If responder's first bid was 1♠, opener shows 4 ♥ before showing 3-card ♠ support. If you require opener to jump to show a maximum, this allows you to stop at the 2 level whenever opener has a minimum and responder only has an invitational hand. With weaker hands, the 5-3 sometimes plays better because you have better trump control.
