You play 2-way nmf over partner's 1NT rebid.

 

1. What is your call at MP's?

 

2. What is your call at IMP's?

 

3. What is your call at Swiss teams (8 board rounds)?

3N. Obv we have slam sometimes opposite hands like Kxx Ax Kxx Kxxxx but I don't want to give them information, and partner will drive past 3N on hands that look good but aren't like KJx Axx xx KQJxx if we try for slam.

I want to make one more inquiry, but I would need to know if the inquiry will help. I don't think we are necessarily giving away that much by doing this, and I think the chances of slam making are not that remote.

 

However, I'm not sure what the options are or what partner will say.

 

If, for example, a 2♦ GF would yield a 3NT call only if partner has a primed 5323 (Justin's hand), then that works really well, at not that much cost. On the other hand, if I'm going to get some sort of muddy next call, then make a muddy 3♣ call, and get some screwing around and guessing, then 3NT immediately seems preferable.

True, if I could find out partners shape I would find that worthwhile since 2-5 is really good for us.

If it were regular NMF, it would go like this:

 

1♣ - 1♥

1NT - 2♦!

2any - 3♣ = cancels the interest in ♥ and shows the real interest is in ♣, and establishes GF, slammish.

 

I'm thinking it would be the same here, except the 2D! has already established the GF.

But you asked for my call. What are the odds of finding Justin's 5 control hand for Opener?

I don't think Responder really is good enough for a slammish call.

3NT.

There are 2 other ways for Responder to reach the 3C bid:

1♣ - 1♥

1NT - 3♣ = invitational or weak ( prior discussion determines which in reg NMF)

 

1♣ - 1♥

1NT - 2C! ( forces 2D in 2-way )

2D - 3C ( this could be invite and the above as weak in 2-way )

I definitely check back. What if partner is 3145? Then we would only need Kxx x Kxxx Kxxxx for slam!

This was my reaction as well. Even then, plenty of 1N rebids make 5♣ better than 3N.

In fact why not Kxx A Kxxx Kxxxx for the grand, wooooooooooootttttttt. Or for that matter KQx A xxxx Kxxxx or so. The more I look at this the more I strongly believe you should check back. The perfect 8 count (above hand less heart ace) is slam. You just need agreements to make sure partner won't automatically assume you have 5 hearts.

I am defaulted into 2D (whether 2-way or one-way NMF). Easier in two-way when it creates GF and I don't need to worry about wrong strain or level when bidding will not end below game.

Interesting. I always thought the GF option in 2-way deprived responder of finding out whether opener was mini or max --whereas, plain old nmf had strength and shape included in the responses. If wrong, I would appreciate finding out how the answers work in gfnm.
