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
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

1♣-1♦       strong (16+); negative (0-8)
1♥-1♠       stronger (19+); 2nd negative (0-4)
?
...

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♠: 4♥s & 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♥: 4♥s & longer ♣s, 19-21
2♠: 4♠s and longer ♣s, 19-21
2NT: 4♦s 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♠: 4♠s 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).

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
...

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 4♠s, 16-21
2♦: 5+♦s, fewer than 4♠s, 16-18
2♥: 5+♥s, fewer than 4♠s, 16-18
2♠+: shapely hands
