no opp bidding

1H - 1S - 1N - 3S

1H - 1S - 1N - 2C (checkback) 2m 3S

1H - 1S - 1N - 2C (checkback) 2m 2S


not sure what the difference is between all of these, 1H - 1S - 1N - 2S would be sign off btw

Seem to remember the difference between first and second is one is invitational and one is forcing but intrigued as to what the final sequence might mean.

Thanks,

Eagles

Here's how I usually play them but might not be standard (2C always shows invitational hand at least):

1H - 1S - 1N - 2S
To play

1H - 1S - 1N - 3S
Invitational, 6+ spades

1H - 1S - 1N - 2C (checkback) 2m 3S
Sets trump, demands cuebid

1H - 1S - 1N - 2C (checkback) 2m 2S
Invitational with an unbalanced hand, does NOT promise more than 5 spades

The third sequence may change if you play strong jump shifts, the first if you play WJS, I'm wondering what shape you would have with only 5 spades for the 4th, and what you play 1♥-1♠-1N-2♣-2♦-3m as ?

5134/5143/5125/5152/5044, invitational (not strong enough to bid 3m)

This is game forcing, natural

Within an Acol context, the difference between the first and third sequences will normally be that the latter implies 3 hearts whereas the former denies this. I always thought this was a pretty silly part of NMF and that there ought to be better ways of using these sequences. I have not found a lot of good material for this either - it seems to be assumed that you will move onto 2-way by the time you start asking these questions. There is a little more available for 5 card majors of course.

OK, so what's 1♥-1♠-1N-3m ?

I'm asking like a novice because I play Crowhurst rather than straight checkback which I've never played.

Weak, 4s/6+m, to play

I think it is natural and invitational in classic NMF but many play around a little bit with the 2NT and 3♣ calls to get extra options.

IMO, the continuation structures (preferences) that we should have thoroughly discussed before using the 2C checkback should be in a different forum, regardless of how inexperienced the OP thinks he is.

But I will point out that 2m can only be 2♦, the bid itself should mean something, and the meaning of 2D in-turn might affect the meanings of the various continuations.
