olien Posted September 19, 2010 Report Share Posted September 19, 2010 I'm trying to figure out the best structure possible to show balanced hands after a strong 1C opening. Our balanced hands include: 5♠(332), 5m(332), any 4333, and any 4432. We want to have our strength divided into 3 ranges in as many situations as possible, but having only 2 ranges, when necessary, is OK. Our balanced hands effectively go through 1C-2C and 1C-2D (with some bids in-between in the latter auction which are not relevant). We are also trying to make the structure as symmetric as possible. The structure we have now is:1C-2C shows balanced 8-11 (but could be more with 33(43) or 4S-4D).After the 2D relay, 2H=33(43) or 4S-4D any strength, and 2S+ are like 1C-2D// 2H. That structure is:2S 5m(332) or 4-4 minors (now 3C=5C, 3D=4/4 minors, 3H+=5D zoom->doubleton)2N 5S(332) or 4-4 majors (now 3D=4/4 majors, 3H+=5S zoom->doubleton)3C 4H-4C or 3433 (now 3H=2434, 3S=3424, 3N=3433)3D 4H-4D 3H 42343S 43243N 4333 Right now, we have 2 ranges: 8-11 and 12+, but are trying to devise a more efficient structure where we can have narrower ranges (maybe 8-10, 11-13, 14+ or similar). Or where we can keep the same two ranges, but maybe have like a 3S size ask bid available at the close of more auctions. All suggestions would be welcome.

hrothgar Posted September 19, 2010 Report Share Posted September 19, 2010 For what its worth, I think that resolving the range of various GF hands before you show shape makes life WAY too complicated. Here's the relay structure that I typically use to show balanced hands In theory, you could use a 1N response to show 1 range and bids from 2♦+ to show the other. 3♠ = 2-3-3-5 shape3♥ = 3-2-3-5 shape3♦ 3-3-2-5 shape3♣ = 2-3-4-4 or 3-2-4-4 shape2N = 5332 with primary clubs2♠ = any 4333 shape2♥ = 4+ Spades, 2-3 Hearts, denies 4-3-3-3 shape2♦ = 4+ Hearts, denies 3-4-3-3 shape After 2♥, 2♠ = relay and then 2N = 53323♣ = 4 Hearts and 4 Clubs3♦ = 2-4-4-3 shape3♥ = 3-4-4-2 shape After 2♦, 2♥ = relay and then 2♠ = 4 Spades and 4 Hearts2N = 53323♣ = 4 Spades and 4 Diamonds3♦ = 4-2-4-3 shape3♥ = 4-3-4-2 shape Quote Link to comment Share on other sites More sharing options...

I'm pretty fond of the relay scheme that I listed...Its very symmetric and very easy to remember. Potentially, you might want to consider giving up on the split range with the balanced hand types. This should save you quite a lot of space. In my experience, its far from essentially and eliminating this will really simplify your life. (The relay scheme that I use is based on a 1♦ response showing (almost) any GF hand. We use a RR by the 1♣ opener to limit strength. Quote Link to comment Share on other sites More sharing options...
olien Posted September 19, 2010 Author Report Share Posted September 19, 2010 We could re-arrange our responses to use your suggested structure: 1H=5+S or any balanced hand2C=4S unbalancedrest=same after 1C-1H// 1S-1N=balanced, and 2C relays and puts us on track with the suggested structure. Have you had problems with wrong-siding contracts with responder "stealing" the NT contract, and declaring more hands with known distribution? As an aside, the 1D response as almost any GF, does this work well for you? Do the opponents not interfere in a way that's bad for you? How does this initial response structure look when typed up?

olien Posted September 19, 2010 Author Report Share Posted September 19, 2010 As a note, in ACBLand, any non-1D response to 1C which is artificial MUST be game-forcing. So, I guess whatever you have just wouldn't be allowed :) But, I would still like to know your experiences with siding issues with the balanced responding hand bidding 1NT.

Do the opponents not interfere in a way that's bad for you? How does this initial response structure look when typed up? I like 1♣ - 1♦ = most any GF 1. We're able to immediately show shape with semi positive hands which forestalls many competitive auctions. 2. If the opponents do intervene after 1♣ - (P) - (1♦) we have an unambiguous forcing pass established which makes life a LOT easier. 3. The strong club opener can immediately reverse the relay and limit strength 4.

zenko Posted September 20, 2010 Report Share Posted September 20, 2010 If completely artificial responses are not an issue, the optimal space-conserving structure is one based on Fibonacci numbers tree, since it is mathematically the most efficient one. Curiously enough it is also the easiest one to remember IMO, once you grasp the basic principle its a breeze. http://en.wikipedia.org/wiki/Fibonacci_number Quote Link to comment Share on other sites More sharing options...

Glen is correct that all artificial responses are allowed after a strong opening. How do you think the standard players get away with 2♣-2♦ waiting, 2♥ negative, etc? Same rule.

rbforster Posted September 20, 2010 Report Share Posted September 20, 2010 Hrothgar, our response structure doesn't allow for this. Our response structure is: 1D=negative1H=4+S or 12+ balanced (if only 4S, then 3-suited or longer minor)1S=5+H1N=5+C (could be 5-5 minors)2C=8-11 balanced (or 8+ if 33(43) or 4S-4D)2D=6+D2H=4+H 5+D2S=1444, 04(54), 44(50)2N+=5+D 4CIMO, going with the split range for balanced hands isn't a good plan and I'm not sure when people do this playing relays. I guess it helps if you only think as far as the first response to a strong club and then "bid naturally" and need a way to show extras or not. I think there are two more big choices here: 1) Do you want to include 5332 hands as balanced?2) Do you want to right-side NT? I certainly prefer #2, and would ideally like to include 5m332 as balanced as well. 5M332 I think would be best showing the major, but if you play symmetric relay that'll screw up your major-minor single suited responses. In my strong club, I compromised and used the following: 1C-1S balanced (4432/4333 only) or 1-suited clubs1N-2C just clubs (which includes 5332)......2D+ balanced hands (use TOSR if you want, but I've got better relays if you ask :unsure:) Shape resolves at 3D/3H typically, so you can get a cheap range-ask in at that point and only go past 3N when responder shows the 3rd step in values (so it's probably ok). In an older version of a strong club I was taught, we used 1S for all balanced hands including all 5332s. There were some nice relays after this that resolved at 3C/3D/3H(zoom), so lots of space for showing strength later. I eventually decided on the above version instead since I thought I wanted to allocate more bidding space to the unbalanced hands for slam investigation.

straube Posted September 20, 2010 Report Share Posted September 20, 2010 I agree with RobF about not dividing your balanced hands into two or more ranges. Find your strain before you look for extras. Also, if you have multiple bids for strengths they'll go unused when you're relaying out your passed hands. Quote Link to comment Share on other sites More sharing options...

rbforster Posted September 20, 2010 Report Share Posted September 20, 2010 I am a fan of shape before strength. That said, strength is important and needs to be sorted out below 3N, which is the tightest constraint of all game hands. I would want to make sure I left enough space to resolve full shape with a top bid of 3H ideally. This means that the top shape shows 3 strength ranges without passing 3N (3H/3S/3N zooming), and the second top shape still shows 2 range (3D shape - 3H® - 3S/3N/4C zooming). All lower shapes get 3+ ranges. If you don't have space for this in your system, I would consider reworking your system. Balanced hands are VERY common, so you should handle them well. If this means you have to screw up your shape relays on some 7330 shapes, well, those are very rare and much more likely to be contested auctions too.

Free Posted September 20, 2010 Report Share Posted September 20, 2010 For balanced hands you can also use 2♦ as a relay (2♥ is too high though). Therefor 2♣ can be used to show a balanced hand, and you can use several ways to get there (1♣-2♣ or 1♣-1♥-1♠-2♣ for example) to show various ranges. I agree with Richard that it makes things more complicated to show various ranges immediately. After 2♦ relay:2♥ = 4-5♥...2NT = 5♥332...3♣ = 4♥-4♣......3♥/♠ = 2-3/3-2...3♦ = 4♥-4♦......3♠/NT = 2-3/3-2...3♥ = 4=4=2=3...3♠ = 4=4=3=2...3NT = 3=4=3=32♠ = 4-5♠...3♣ = 5♠332...3♦ = 4♠-4♦...3♥ = 4=2=3=4...3♠ = 4=3=2=4...3NT = 4=3=3=32NT = 5♣332/3=3=3=4...3♦/M = 5332...3NT = 3=3=3=43♣ = 4♦-4♣...3♥/♠ = 2-3/3-23♦/M = 5♦3323NT = 3=3=4=3 This is pretty symmetrical. If you want to rightside the contract more often, I suggest to reverse the meanings of 2M. Since opener has bid both minors (1♣ opening an 2♦ relay) there's no need to reverse these as well. You could however bid the suits up the line if you prefer that. If you want 3 ranges, it may be useful to combine the weakest and the strongest in 1 call. That way, responder can zoom if he holds the strongest possible holding. Suppose you want 8-11, 12-15 and 16+. Combine 8-11 with 16+ in 1 response. Then, if opener relays and responder would bid 3NT, he can bid 4♣ to show the 4333 with 16+HCP. Also if opener wants to signoff, responder can still bid something else.

akhare Posted September 20, 2010 Report Share Posted September 20, 2010 Adding to the chorus here -- define a QP base (A=3, K=2, Q=1) for opener (suggest 9/10) and the positive responses (suggest 6 with some 5) and don't worry about strength until after you have resolved shape. In most cases, you will know the combined strength below 3N (need in the ballpark of 20 QPs to consider slam and little less with shape).

Zelandakh Posted September 20, 2010 Report Share Posted September 20, 2010 Hrothgar, our response structure doesn't allow for this. Our response structure is: 1D=negative1H=4+S or 12+ balanced (if only 4S, then 3-suited or longer minor)1S=5+H1N=5+C (could be 5-5 minors)2C=8-11 balanced (or 8+ if 33(43) or 4S-4D)2D=6+D2H=4+H 5+D2S=1444, 04(54), 44(50)2N+=5+D 4C The simple solution to your problem is to include all the balanced hands with 4-5 spades in your 1H response and the balanced hands without 4 spades in your 2C bid. Within your original concept this might mean 1C - 1H - 1S - 2D - 2H2S = 4 hearts, 4 spades2N = 5S3323C = 4 spades, 4 diamonds3D = 43333H = 4=2=3=43S+ = 4=3=4=2 and1C - 2C - 2D2H = 2-3 spades, 2-3 hearts2S = see below2N = 5H3323C = 4 hearts, 4 diamonds3D = 34333H = 2=4=3=43S+ = 3=4=3=4 I left a gap at 2S because it spoils the symmetry of the structure (giving an overhead on memory). One option would be to use this bid as a 3-suiter without spades. You could, of course, also split the 'no major' balanced hands between 2H and 2S. FWiiW I split my balanced hands up like this but in a way that always shows a major if I have one. Thus 1C - 1S (no major) - 1N - 2H = balanced with no major1C - 2D = 4-5 hearts, 0-3 spades, balanced or 3-suited (then all rebids from 2NT up are balanced)1C - 2H = 4-5 spades, 0-3 hearts, balanced1C - 1H (spades) - 1S - 1N (hearts) - 2C - 2D = balanced or 3-suited (then 2S= 4432/4441) Looking over your structure I would suggest a further tweak, namely switching round your 1S bid with your 1NT and 2C bids, ie 1C - 1S = balanced, or clubs1C - 1N = hearts and clubs, or heart 1-suiter1C - 2C = hearts and diamonds This makes it more likely for the strong, unknown hand to be declarer in NT when that is most likely to be the final contract. It has no effect on anything else as these 3 bids form a closed system. You could, of course, instead do a similar thing with your 2C and 2D/2H responses to give1C - 2C = 6+ diamonds, or 5+ diamonds and 4 hearts1C - 2D = various balanced hands (eg 4-5 hearts)1C - 2H = various balanced hands (eg no major) You do lose out on being able to show the hearts immediately. An option to show the hearts would be to then switch your 5D4H hands with your 5D4C hands. Thus1C - 2C = 6+ diamonds, or 5+ diamonds and 4 clubs1C - 2N+ = 5+ diamond and 4 hearts So my 2 suggestions for tweaking your responses are 1D = neg1H = 4+ spades, or some balanced hands (eg 4-5 spades)1S = balanced, or 5+ clubs1N = 6+ hearts, or 5+ hearts and 4+ clubs2C = 5+ hearts and 4+ diamonds2D = 6+ diamonds2H = 5+ diamonds and 4 hearts2S = 3-suiter with 0-1 hearts2N+ = 5+ diamonds and 4 clubs and 1D = neg1H = 4+ spades, or some balanced hands (eg 4-5 spades)1S = 5+ hearts1N = 5+ clubs2C = 6+ diamonds, or 5+ diamonds and 4 clubs2D = various balanced hands (eg 4-5 hearts)2H = various balanced hands (eg no major)2S = 3-suiter with 0-1 hearts2N+ = 5+ diamonds and 4 hearts Finally, you can combine these 2 schemes as follows:- 1D = neg1H = 4+ spades, or some balanced hands (eg 4-5 spades)1S = 5+ clubs, or 6+ diamonds, or 5+ diamonds and 4 clubs1N = 6+ hearts, or 5+ hearts and 4+ clubs2C = 5+ hearts and 4+ diamonds2D = various balanced hands (eg 4-5 hearts)2H = various balanced hands (eg no major)2S = 3-suiter with 0-1 hearts2N+ = 5+ diamonds and 4 hearts I think each of these 3 schemes is a small improvement on the original, albeit that the benefits are not large enough to warrant picking any above something you are comfortable with. As you can probably tell from my earlier ramble I take all of the GF hands without a major and push them into a 1S response. If you were also to do this then you would free up the balanced hands within 1H to go back to being 12+ if desired. There is enough space to do this (so long as you move the 4 hearts and 5+ clubs hands elsewhere).eg1C - 1S - 1NT2C = 6+ diamonds, or 5+ diamonds and 4 clubs2D = 6+ clubs2H = balanced2S = 5+ diamonds and 5+ clubs2N+ = 5+ clubs and 4 diamonds If you want to stick with your 12+ balanced option then this would be my proposed solution (under the caveats of others that this may not be optimal since you cannot fully resolve the shape). 1D = neg1H = 4+ spades, or 12+ balanced1S = 0-3 hearts, 0-3 spades (if balanced then 9-11)1N = 6+ hearts, or 5+ hearts and 4+ clubs2C = hearts and diamonds (at least 5-4)2D = 9-11 balanced with 4-5 hearts2H = 9-11 balanced with 4-5 spades and 2-3 hearts2S = 3-suiter with 0-1 hearts2N+ = 5+ clubs and 4 hearts Hopefully this final possibility is the kind of thing you were looking for. In reaching it we have lost the ability to promise 5+ hearts when we have both red suits. As that was a premise of your original concept it might be a step too far for you. I do not think there is a better way for you to get your split NT ranges though. Quote Link to comment Share on other sites More sharing options...
dake50 Posted September 20, 2010 Report Share Posted September 20, 2010 Do you expect top range to zoom above the responses for lower range if/when relayed?That trades back space when slam/grand is most likely. Or just hope good answers keep relayer continuing for slam/grand? Can the top range then ever decide to up a slam to grand with unshown values? I have similar partitions to get asks simplified --at least for common shapes/strengths. There remain some that just persist as "by guess and by golly".

Our balanced hands include 5S-(332) and 5m(332), and all 4432s and 4333s.

straube Posted September 20, 2010 Report Share Posted September 20, 2010 just curious what olien is looking for now. Is keeping 1S as 5 hearts essential? How much space does he want to devote to the balanced hands. Quote Link to comment Share on other sites More sharing options...
