Removing unbalanced minima from a short diamond
#1

My existing opening structure is -
1c = nat/17-19nt
1d = nat/11-13nt
1M = 5 cards
1n = 14-16
2c strong
2d+ preempts
How about this instead?
1d = 11-13 NT or 14+ with diamonds
2c = strong, or 10-13 with 5+d, unbal, no major
2d = 5+d,4M 10-13
Edit: It would also be quite easy to make 1c unlimited, removing gf club hands from the 2c opening.

I like your idea but I think 2C could promise 6D and with less than 14 and 4C and 5D you open 1C.

1C 15+ (bal, with clubs, or 15-17 with 5M)
1D = 11-22 unb with at least 4D can be 4D+5C or (4441)
1M =11-14 or 18-21
1NT 12-14
2C = 5C+4M 11-14 or 6C
Balanced hands ----IMO all 16+ bal hands are better under a strong clubs, the 15 count do better under a strong NT than under a strong clubs but the 14 do almost equally well under weak NT/strong nt. VUL its a bit annoying to open 1NT with 12-13 but its somewhat compensated by when we are not vul. Opening bal 11 count in 1D is pointless imo. So i think its a draw here. Im under for the 12,13,15 slighty under for the 14 but im significantly better placed for 16+ and my 2NT is free.
real clubs ---- Im at a big disadvantage here. Not only 2C opening lead to some problems but when your opening 1C in your methods its real clubs very often if not its a big bal hand so good edge for you here.
Real diamonds ---- Big edge for me here. Having diamonds in 3 different bid is a bit annoying for me. Also I have my weak 2D.
Majors ---- again big edge for me, Ive got many of the advantages of a limited opening style.
unbalanced powerhouse ---- again decent edge for me because of the strong clubs structure.
IMO its a no brainer that you should switch your nt ranges 1C (11-13) and 1D (17-19).
If you want to maximize your 2C opening, use 2NT for 22-23 and 2C is 21+ unb, 24+ bal or 20-21 bal with some ways to stop in 2M.

I happen to think it's a very noble way to meet one's maker, especially for a guy like him.
Bottom line is we never let that difference of opinion interfere with anything."

I played this a long time ago with the middle range in 1♦, the club unlimited if balanced and forcing with a negative or balanced 1♦, and a big unbalanced 1N.

I disagree with most of this - there's a reason Meckwell play 2NT = 19-20, and a reason that most Precision pairs open 1D on bal 11s - but I don't disagree that we are roughly even on balanced hands overall.

No. I think you have an edge but it's tiny compared with my edge on club hands. I'll frequently have gains from the 2C/2D openings.

No, you'll lose plenty on the 15-17 hands to counteract the gains on the 11-14 hands.

Probably, but I'd need to see your continuations.

No. This screws you over on the 17-19 no-trumps for very little gain. It also leads to frequent and hideous wrongsiding after transfer responses on auctions like 1C-P-1H!-2H; 2S, which I explained to you in a thread you started on transfer responses to 1D.
Quote
Yeah I've tried putting 20-21 bal through 2C, it gained me a grand total of 2 imps, and cost me an (unlucky) NV game swing; the problems it caused us in contested auctions were hideous in comparison, although maybe that was down to lack of discussion/practice with the method on our part.
If future responses could be on topic, i.e. comparing the two suggested systems, rather than some alternative nutjob method, that'd be appreciated, thanks.

Are you intending to treat hands with 6 diamonds 322 and 22(45)s as balanced ?
Difficult to assess without knowing these things.
And I'm sure Hanlon/McGann are amazed you think rebidding a 3 card major with 11-13 is a nutjob method, IIRC they've done this for years.

Not precisely, I was thinking maybe those with experience playing 2C as gf/weak 2D might weigh in.

2245 is handled very well through 1C, no reason to open 1D on it.
6D322 10-13 would be happy to open 2C IMO.
2254 10-13 would tend to be treated as balanced I think.

Sure, but in a different context. Transfer responses have largely superseded alternative methods over a nat/bal club.

Transfers over 1C are very powerful and its not just for rightsiding its also to give you more sequences. 1C-1D (hearts) & 1C-1H (spades) is gaining a huge step over the equivalent 1C-1H & 1D-1H (hearts) 1C-1S,1D-1S (spades) So its really obvious that you would gain on transfer sequence with the more probable hands 11-13 vs 17-19 hands, the frequency difference is huge. It will be hard to find an experienced system designer that will agree with your switch. If you really want to rightside your 17-19 hands do like me and play a strong club with transfers. We accept the transfers with 3 so
1C-1D(H or pts)--1H (show 3)
1C-1H(S w or GF)--1S are our most common start so we rightside 95% of the case were have a M fit and opener is 15+. Even hand where we dont accept the transfers.
1C-1D-1Nt (17-18 withouth 4H)
1C-1H-1NT (15-20, 0-2 S)
we have a good chance to retransfer later.
I don't really agree with the rest of your post also but its irrelevant in compared to this.
Do you at least know the frequency difference between 11-13 and 17-19 ?

The frequency is irrelevant unless you are actually gaining something on the hands. The best continuations over 1c (nat/weak NT) gain a lot more on the club hands than the weak no-trumps.
Does Glen Ashton count as an experienced system designer?

Yes that occurred to me, as did opening 1M on 4M5D to leave the 2D opening free. I kinda like that, as it stands, if they take advantage of being able to double our 2C opening, they are giving up something significant, i.e. letting us out in 2C X when opener has 5D4C.

I think many bridge players are experienced system designers. MickyB and Benlessard both clearly qualify. I was a vastly experienced system designer by my early 20s*. If we're doing appeals to authority, it would be more relevant to consider whether they're successful system designers.
*I found some of the results recently. They're now performing a useful function in my compost bin.

If you're so worried about diamond hands, why don't you just come back into the fold of T-Walsh orthodoxy and put both 11-13 and 17-19 into 1♣, making your 1♦ opening all about diamonds? Or does that count as a nutjob alternative as well?

Well, then I'd worry about club hands and 17-19 no-trumps instead, both of which benefit greatly from not making the same opening bid as 11-13 no-trumps.

Meh. Semi-nutjob :-p

Mike doesn't want any minimum unbalanced hands to open the same thing as the minimum balanced hands.
Actually, that suggests a new way to hijack this thread:one way to solve this problem is to get the opponents to open 1♦ in front of you, so that you can pass with the minimum balanced hands.

I think you would be better off playing a weak NT and making the balanced range within 1♦ 14-16. That way the bottom end of the range is more consistent, which helps with homogeneity. You could of course just go with a Mexican 2♣ or 2♦ opening and just have the 1♣ opening as nebulous, using transfer responses to sort that out at a low level.

As to the question of this thread it's a good one, and while the current short club/unbal 1D is better than standard, I don't think it is best, and I much prefer Italian methods that park 18-19 or 18-20 bal into 2C, and it turns out it is quite safe moving standard 2C hand types into a 1C opening, given how both light responses and the Polish Club are proven.

I'd also be worried about finding major suit fits over the 2♦ opening, especially on non-GF hands. Just because I know opener has a major doesn't mean I have the same major; for example say I hold ♠AQxxx ♥Kx ♦xx ♣xxxx; I might make game opposite ♠Kxxx ♥Qxx ♦AQxxx ♣x but don't really want to get higher opposite the more likely ♠x ♥Qxxx ♦AQxxx ♣Kxx.
Given the general system I'd go with 2♦ showing 6+♦ and intermediate, and let the 4M-5♦ hands open 1♦ where at least I can consistently find my major suit fits. These 1453-type patterns are not that different from balanced hands in most situations anyway (except playing strength when partner responds your 4M).
I do think putting both balanced ranges into 1♣ is better; it's easy to clarify in a non-competitive auction, and when opponents are going to bid I'd rather have one nebulous "usually just a balanced hand" opening than two.

Yeah I'd probably do that when NV or 1st NV with some partners but didn't want to over-complicate the OP. Going this route does have downsides, you have a lot more tricky decisions on the diamond hands, playing my suggested method the diamond hands are normally happy to show extras over a NFB/transfer. This is pretty much a rehash of the Polish Club vs Millennium Club/Nightmare/Fantunes 1C argument.

While I think 2m as 18-19 bal is a decent idea, I prefer opening 1D rather than 1C with weak NTs. Besides the right-siding issues already mentioned [1C-P-1H!-2H; 2S], allowing 1C-P-1H!-X isn't great - I'm not convinced the gains outweigh these losses.
