After a 1 negative response to a strong club, I like to play 1 artificial with extras (bids other than 1 deny extra strength by opener) and the 1 reply is a 2nd negative. This seems to be at least a somewhat popular method (rather than jumping to show strong hands over 1-1). My question is how best to continue after the 2nd negative:

1-1       strong (16+); negative (0-8)
1-1       stronger (19+); 2nd negative (0-4)
?

I currently use this scheme:

2            artificial and very strong 22+ (then using standard "strong 2C" methods)
1N            20-21
2,3   5+ nat and limited 19-21

The obvious downside to this method is that with some extra values (~19-21), hands with clubs must bid at the 3 level even if they might be only 5/4 with clubs and another suit.

If you play a 2nd negative, how do you handle this issue? I can think of a number of possibilities, and I hope you'll comment if you've played any of these or on which you think might be good/best:

- play something besides an artificial 2 to show very good hands
- bid 3 with only 5 opposite a 2nd negative and hope for the best
- make 3 show 6 by either bidding a semibalanced 1N (20-21) or a wide ranging 2 earlier (so 1-1-2 is 16-21 instead of 16-18).
- something else?

Thanks!

We used to play everything was natural even 2, and every jump to the 3 level was natural unbalanced+GF. The situation seems so infrequent that it's OK to do it.
... and I can prove it with my usual, flawless logic.

I recommend looking at schemes used after 1 double negative

For example, I know that Marston uses

1N as natural (and wide ranging)
2 as an artificial game force
2 as a canape transfer

I read in some of his documents of 2007 that he plays:
2 = 44+M
2 = 6M
2M = 5M, 4+m
And I think that there are some strong versions in 2 and/or 2. Has he switched back?

Its possible that this might have changed

If life ever calms down at work I'll try to figure things out...

1-1       strong (16+); negative (0-8)

?
...

I think for useful space reasons it would be better to put the 19-21 s into 1 rebid to 1:

1-1       strong (16+); negative (0-8)
1 = 16-21 s (this also "right-sides" more contracts)

Then one has a "free" 2 bid after this sequence:

1-1       strong (16+); negative (0-8)
1-1       stronger (19+); 2nd negative (0-4)
?

Now it depends on how much science you want to throw at this - in effect with 22+ you arrive at a situation like 2-2 (bust) in that style in standard, but unable to pass 2 - bids of 2+ can all show strong hands. One approach would be like suggested in the ACBL bulletin, after the 0-4 1 negative:

2//: 19-22 (i.e. good but less than a GF), 5+
2: s or balanced, GF
2NT: 22-24
3//: natural GF
3: 4s & longer s, GF

Another approach is re-map the 19-22s:

2: 22+
2: 4cM and longer minor, 19-21, 2M pass or correct
2: 5+s, 19-21
2: 5-4/4-5+ in minors, 19-21 - 2NT asks longer minor
3/: 19-21, 6+ minor

Likewise:
2: 4cM and longer minor, 19-21, 2 asks major
2: Any GF
2: 5+s, 19-21
2: 5-4/4-5+ in minors, 19-21 - 2NT asks longer minor
2NT: 22-24
3/: 19-21, 6+ minor

Various options there, some good, some not-so-nice.

Another approach is have 2 do some double duty, and employ transfers, to get extra bidding space (not to transfer, since all 4 suits already bid):

2: 19-21 5+s or any GF or 22+ balanced
2: 5+s, 19-21
2: 4s & longer s, 19-21
2: 4s and longer s, 19-21
2NT: 4s and longer s, 19-21
3: 6+s, no 4cM, 19-21

or just the 2 transfer:

2: 19-21 5+s or any GF (22+ if unbalanced)
2: 5+s and 4 of a red suit, 19-21
2: 5+s, 19-21
2: 4s and longer s, 19-21
2NT: 22-24
3: 6+s, no 4cM, 19-21

and if you want 1 to be less than 19:

2: 19-21 5+s or any GF
2: 5+s and 4 of another suit, 19-21
2: 5+s, 19-21
2: 5+s, 19-21
2NT: 22-24
3: 6+s, no 4cM, 19-21

After the sequence 1C- 1D
1H- 1S (0-4)
?

1NT= 19+ to22-
2C = art GF with full relay responses a la version symmetric modified
2D/H/S= nat encouraging but nf
2NT= C as above
3C= 5+5+ Rank
3D= 5+5+ Colour
3H = 5+H & 5+C nf but highly encouraging
3S = 5+S & 5+ D as above
3NT= T

One variation would be to borrow the Romex sequences after 1NT-2C auctions.

Over 1C-1D; 1H-1S:
1NT = 20-22 HCP
2C = 22+ GF (other than 1NT, all others shows 19-21)
2D = ask for 4CM
2M = 5+ in bid major
2N = 5/4 in minors
3m = 6+
3H = 5+/5+ in majors, 4 losers
3S = 5+/5+ in majors, GF
3N = 5+5+ in minors;
4m = 5-5 in majors, 3 cards in m, void in om
4M = 1-suited


You should carefully address the continuations other than the 1S relay: 16-18 HCP hands are more frequent than 19+, and good part scores can be key.

Moscito (pre-semi-positive responses) had some elegant continuations.

The Viking Club has something simpler:
1C-1D
?
1S = 5+ spades or 4 spades and 5+ minor
1N = 17-19 (if you are playing a 14-16 NT)
2C/2D = 5+, natural
2H = 5+ hearts, normally unbalanced
2S = puppet to 2NT after which:
... 3C = 6+ clubs and 4 hearts
... 3D = 6+ diamonds and 4 hearts
... 3H = 6+ hearts and 4 spades
2NT = 5440 with 5 hearts
3C = 5+ clubs and 5 hearts
3D = 5+ diamonds and 5 hearts
3H = 6+ hearts and 5 spades
3S = 9 tricks with spades as trumps
3N = To play

Do check out the continuations in the Toad Club -- they are an impressive 5 pages long:

Not in 1H are hands where opener can bid to show which Q/J are wanted. Eg. 2C =S+C so only single/void in red or red A is valuable, but any black honor. Raise on 4-7 adjusted.

Hi Glen. Thanks for all the detailed suggestions. I agree with you in general that the cheapest bids over 1 should include a wider range of hand types along the useful space lines.

I wasn't entirely comfortable with some methods I've seen where 2N or somesuch shows 4+/5+ minors. This seems pushy to me when you're only 54, and having such a bid with 5/5+ is fine but doesn't solve the problem of what to do with the 4=5 minors hands. Here's a proposal that seems better than what I have currently anyway, at least in terms of how it treats the 5 hands. Along the useful space lines, I've added the troublesome hand types to the cheapest bids 1, 1N, and 2 after 1-1:

1-1:

1 art 19+, many (but not all) hands extra values
1 art but usually 4+. Min H+m, S+m, or majors. Minimum with 6+ spades. Some special distributional hands including 4/6 extras
1N 16-19 semibal shapes include (31)(54), 22(54), and all 4441's and 5332's.
2 5+. Min hands with 6+ or extra values hands with 5/4X
2 6+ natural min
2 6+ natural min
2+ special distributional hands, including 4/6 extras and 5/5 minors min

After 1-1-1-1, 3 is 6+ extras and no 4cM.

Note that additional hands have been added to 2 as well, but by including the minimum club 2-suiters (4M/5) in 1 means that 2 will either have extra shape (6+, could be 6-4) or extra strength (~19-21 instead of just ~16-18). Then over an asking bid of 2 you can separate things pretty well:

1-1-2-2 ~4-7 asking bid, ala precision 2-2:

2M   4M ~16-18 (also with 6+ clubs)
2N   6+ inv (~18-19), no major
3   6+ min (~16-17), no major
3   4 max ~19-21 (with exactly 5)
3M   4M max ~19-21 (with exactly 5)

If you think about including the hand with xx45 and minimum strength in the above 2, you don't really have enough space to show all the minimum hands below 3 and still allow the long club hands to show if they'd accept partner's invitation. This is why I moved the xx45 hands to 1N (which hopefully causes fewer problems).

...

I like your idea of expanding the 1-1;-2 range. I would not distort 1 or 1NT beyond natural - perhaps something like:

1-1;-?
1: 19+ except not 19-21 unbalanced with 4+s and/or 5+s
1: 4+s, 16-21, may have longer second suit, not balanced
1NT: 16-18 (or whatever range is necessary)
2: 5+s, fewer than 4s, 16-21
2: 5+s, fewer than 4s, 16-18
2: 5+s, fewer than 4s, 16-18
2+: shapely hands
