Anyone know of any not-foolish and published 2/1 structures that revolve around differing ranges for 1N rebids, like

1C*-1X/1N = 18-19
1D*-1X/1N = 12-14
1N = 15-17,

where * = "could be 2 cards"? Please feel free to offer ridicule....

This is what I play, except with 17-19/11-13/14-16 as my ranges. A very good method IMO. Compared with 1C as nat/11-13 NT/17-19 NT -

- we have better uncontested auctions on unbalanced hands and 17-19 NTs
- we are more preemptive on 11-13 NTs, bidding 1D-P-1M instead of 1C-P-1R [transfer] with little cost to our side
- in contested auctions, we lose out slightly when opener is unbalanced, but gain when opener has the 17-19 NT


I don't know of anything published though, sorry.

MickyB plays this (with a 17-19 rebid I believe). I play this with the minors reversed, so 1♦ caters for the 18-20 balanced.

For me, the chief advantages of having only one balanced range in the 1♣ opening is:

1. We are better placed in competition in that when opener shows extras he is known to be unbalanced.

2. Playing TWalshe we can use opener's rebids to show many hand types not covered by standard nethods. For instance, if I have a fit for responder, I have three ways of raising to 2M, when I rebid clubs I have four ways of rebidding 3♣ and when I have four diamonds and five clubs I can show this and still stop in 1NT. Having two no trump options would limit my options.

Neither of us have rushed to print yet though ....

Well, hell, you could publish AT LEAST SOME OF IT right here, right now....

Jeez. I'll get back to you when I find out how many posts there are under mickyb and philking. Not like searching for "XYZ", now, is it? (more emoticons than I've used in a year.)

It can be played with different complexity levels, right upto full relays in various positions.

Simplest is -

Over 1D, natural in uncontested auctions. Lots of uncontested schemes are already out there but I think it is important to emphasise competing opposite partner's likely weak NT, so neg free bids at 2-level/leb for competing to 3-level, or better still, transfers.

Auctions like 1C (2H) 3C show 7-11 3+clubs, ie partner is to convert to 3NT with the 17-19 NT. Act aggressively as responder if you have relative shortage in oppo's suit and wish to be in game opposite 17-19 NT.

Uncontested over 1C - transfer responses, with completing the transfer showing C+D unbalanced. This frees up your 2D rebid for some kind of raise.

1C:1S implies diamonds
1C:1N shows 5+clubs, 0+hcp. Now 2C = any 17-19 NT, others show unbal hands
1C:2C = 5+spades, 4+hearts, NF. As well as getting out in 2C, this gives you 2D as a strength enquiry
1C:2new = natural, INV. I've always played 1m:2M as 4-8 hcp or so but this cuts across the range of a 17-19 NT quite horribly, better to play the jump as INV and then with 4-8 you can sign-off/invite/gf opposite partner's 17-19 NT as appropriate. It gives you the potential to right-side those contracts too.

A taster:

After 1♣-1♦(4+ hearts):

1♥ = various:
1. Weak NT with 2-3 hearts
2. 4♦-5♣, 15+
3. 14-16 unbalanced with three hearts
4. A good 3♣ rebid with 3♥
5. A 3♣ rebid with deficient high card points
6. A 2NT rebid with six clubs

1♠ = nat
1NT = 4♦ 5♣ 11-14 NF
2♣ = 6 card suit
2♦ = sound raise to 2♥ with four card support
2♥ = bad raise. Usually 12-13 bal with four hearts or 11-13 unbal with three hearts
2♠ = nat
2NT = GF ♣ one-suiter

After 1♣-1♦-1♥, responder usually bids 1♠, then:

1NT = 12-14 bal
2♣ = 15-16 4-5m
2♦ = 4-5m 17+
2♥ = 14-16 unbal with three hearts
2♠ = good 3♣ rebid with 3♥
2NT = nat with six clubs
3♣ = nat, good playing strength but light in high cards

The biggest single gain has been the ability to show good and bad raises to 2♥, which would not be possible if the minimum balanced hands opened 1♦.

Sure, I think you'd expect us both to have better uncontested auctions on the balanced range that we choose to open 1C. I can stop low on 17-19 NTs after 1C:1S, 1N and 1C:1R, 2M when I suspect you get a level higher. Obviously these are less frequent, but I think it's worth it for the extra bit of preemption on the weak NTs. Also, I do have two ways of raising to 2S after opening 1D playing my more advanced methods.

Open 1♣ with any balanced hand without a 5crd suit except clubs and 12-14 or 18-20hcp. Then:

1♣ 1♦/♥ (transfers)

1♥ = unbal without a 4crd major
1♠ = natural
1nt = 12-14bal
2♣ = 18-20bal

From Roy Hughes' book...

you don't get rid of natural 2NT opening to use a 2NT rebid instead?
