Priorities in Responses to NMF

[Bbradley62]

Pickup Partner and I disagreed about this. Probably two separate questions buried in there, but we can sort it out. Thanks!

3♥ showing a max with 4♥. If partner bids 3NT, I'll convert to 4♠

[Siegmund]

Quite possibly more than two separate questions. But, for the two most obvious questions:

 

With cards suitable for both a heart bid and a spade bid, hearts first, to leave room for partner, is my preference (but you will occasionally hear people who are firm believers in 'show support first' or 'unbid suit first.';

with a pickup partner I would never assume that we show min/max. With a regular partner you can agree to do so in a sensible way -- and by sensible I mean making use of 2N and 3C, NOT leaping to 3D/3H/3S automatically. Leaping to e.g. 3H and wasting a whole level of bidding space is IMO worse than waiting one more round of bidding to resolve strength.

3♥ showing a max with 4♥. If partner bids 3NT, I'll convert to 4♠

 

Agree. Although I'd much rather play 2-way NMF. But max with 4 hearts is what I have, and if partner tries 3nt he had to have some reason to bid and that must be 5 spades if not 4 hearts.

I bid 2♥. No need for jumping to 3♥, because it's forcing.

[gwnn]

depends on the system.

 

I personally think best is if nmf promises a rebid and this is a 2♥ bid. but I would like 2♣ to be inv (whether or not it asks for 2♦, I think both are fine) and 2♦ artificial GF.

Not a matter of priorities for us ---since 3H shows exactly 3-4-4-2 AND a max 1NT rebid, all at the same time.

Ditto...for the 1♠ response in a NMF auction: 1m - 1S, 2om - 3H ...

3H-jump = max w/4h and 3s

I've never played NMF, but I have played checkback stayman in the past which starts the same.

 

Now it depends on what you agree: suits up the line, what is min or max,... Since it's a pickup partner, well, no agreements it is. ;)

 

For me 2♥ is natural but wouldn't deny a ♠ fit and wouldn't deny a max. Responder can still show his hand type and strength now. The biggest problem is with slam interest and ♥ fit, but responder can start with 4th suit forcing and rebid ♥ later on. It's not perfect, but it's a pickup partnership... Bidding 3♥ makes this only more difficult unless it specifically shows a fit as well.

Cool. And if you had a minimum with the same distribution?

[Free]

Minimum responses to checkback stayman are:

2♦ = min no fit

2♠ = min with fit

I believe this is the same for NMF.

 

With max there are all sorts of possibilities. Extended CBS uses:

2♥ = max, 4♥, no fit

2NT = max, no 4♥, no fit

3♣+ = max, natural, with fit

 

3♥ is obviously perfect for this scheme, but I'm not aware that this is standard somehow. :unsure:

Hardy adjunct, which has been around for a while:

 

1D-1S

1N-2C

?

 

2D=2spades, five diamonds, minimum

2H=2-4-4-3, minimum (inferential becuase 2-3-4-4 opened 1C, not 1D)

2S=3 spades and minimum

2NT=all maximums without 3 spades (since game is established, a heart fit can be found later.)

all 3-level bids are max with 3 spades and Pattern

3S=3-3-4-3

3H=3-4-4-2

3D=3-3-5-2

3C=3-2-5-3
