Bidding developments in last 15-20 years? Precision et al.
#1
Posted 2019-September-03, 20:50
However, the last time I learned any new (modern) bidding ideas was circa Hardy's _Standard/Advanced Bidding in the 21st Century_ and the 25 series books. From searching online, it doesn't look like there's been anything earth shattering since then.
We'll have to talk about some of the material in Dan's book and the ideas from Rodwell's _Bidding Topics_. But is there anything else from the last 15-20 years that we should look at? Especially for competitive auctions and mini notrump? What about for defensive carding?
Any other thoughts or reading suggestions on my plan?

Although not playing them myself both the European systems, the Polish Club and the Fantunes, have proved to be effective in top level bridge, however, with all this bidding 'stuff' (for want of a better word) various regulatory bodies such as The English Bridge Union and the American Contract Bridge League have rules and regulations what can and can't be used in various competitions.

1. "Meckwell light" -- in particular the sequence 1♣ (strong)-P-1♥ showing most 8-11 hands with other responses above 1♦ (possibly except for 1♠) showing 12+.
2. Invitational natural jump shifts (i.e. 1M-Pass-3m).
3. Reverse flannery responses to 1m (1m-2♥ as weak 5+♠,4+♥)
4. Two-way new minor forcing (or XYZ).
5. Increasing use of transfers in competitive auctions (most basic are after 1M-(X) and after our overcalls, but I see them in other sequences too).
6. A number competitive approaches derived from Robson-Segal's book (fit-showing jumps maybe the most popular of these).
7. Rusinow leads especially against notrump (not new by any means, but seemingly on the rise these days).
8. Woolsey or Multi-Landy as a defense to 1NT.
9. Wider-ranging overcalls especially at the one-level (both the low and high ends seem to be expanding).

In standard methods, opener needs to be able to distinguish the 16-20 hands from the 11-15 hands.

Okay, what do you recommend instead? It seems like most precision pairs do use 2/1 GF. But if that's not right, what do they use?

I haven't used relays much at all to date.
We assume we'll need to incorporate them eventually. But starting out? No. Especially since the material for learning them doesn't seem to be that solid.
We need something straightforward we can talk through and start using.
We've both never used SAYC, and really learning it seems pretty pointless. We've both mostly played precision. (I was actually taught bidding using Rigal's book.) We just don't have a common dialect since precision isn't really standardized.
The perfect is the enemy of the good; we want to get something that works well enough and that we can gradually change as we get more familiar with each other's style.
Maybe I'm wrong and it would actually be far easier to learn symmetric relay or MOSCITO or whatever than to hash out "regular" bidding and the conventions that go with it.
We'd like to try to stay within ACBL's restrictions. Living in the US, we don't really have an alternative for tournament play. So AFAIK, that means a host of silly restrictions on relay sequences and other generally reasonable things.
But our current thinking is that we can find some system notes for a meckwell-lite precision and it'll be close to what we are familiar with. Dan's book seems pretty solid and the parts it omits aren't complicated and could be grabbed from elsewhere.
We mostly want to avoid wasting energy hashing out areas where we don't do the same thing when we can just swap in something more modern that we'll want to use eventually anyway. (for bidding and defense.)
And we want avoid painting into a corner and needing to gut a ton of work to get from good enough to legit good. (And legit good does seem to mean relays now.)
But we don't think moving to cutting edge stuff will be hard if we know what those parts look like and have a feel for what the most important changes are.
Are we wrong about all of this?
It seems like this thread has been extremely helpful and informative, but if you or anyone else disagrees, let me know. It's not like I know what happened while I wasn't paying attention. If I'm way off on what is going to be the best course of action, tell me. That's why I posted here.

Curious what others think of it. awm listed it and his opinion would be very interesting. I think, btw, that he is not fond of reverse Flannery or invitational jump shifts.
If you want something in a hurry, Meckwell Lite could at least be a placeholder. I think Meckwell or even a simplified version of Meckwell would be better. Meckwell Lite's club structure is altogether different.
If you're interested in relays, you might look at TOSR (Transfer Oriented Symmetric Relay) or something like it that uses transfer responses. You'll have to decide after 1C-1D whether to continue with a relay approach (like TOSR recommends) or a natural approach (like Meckwell). I would really avoid Moscito's 1C structure. For one thing, it uses a 1S double negative that severely hampers fit-finding. There's more.
As far as using 2/1 GF responses to 1M goes, I think the issue is that you should want to open 1M light but if you do so and use 2/1 GF then you will be over-utilizing your 1N response. That, I think, was the point of awm's double barreled invite idea and it was also the point of IMprecision's earlier 2/1 non-GF style. I think that Kathy Wei, too, has said that 2/1 GF responses were not meant to work with Precision.

I've got no problem with invitational jump shifts; they are very good in a 2/1 GF system with wide-ranging openings. In fact, I like to play 1m-2M as an invitational jump shift too (as mentioned above). This approach is okay in a strong club also, but I slightly prefer weak jumps because I can play a wider range (like 0-9) that would be hard to cope with in a system where opener can have 17-20.
While I obviously think relays are good, I don't feel like I've seen them increasing in popularity at the upper levels. There are a few elite pairs that use them of course (maybe more in Europe than the US, which is interesting given that strong club is relatively more popular among top US pairs as far as I can tell).
There's a really big advantage in being consistently on the same page with partner, and this advantage tends to outweigh the incremental benefits of slightly better system. This may encourage pairs who play only occasionally to stick to simpler methods, and I think it's also a big factor in the popularity of using 2/1 GF combined with strong club. There are a number of alternatives but they tend to be much more complicated (my own methods included).

Awm, do you have a write up of your stuff?
Straube, do you have a write up of Meckwell / R-M that you recommend? I've found sketches but nothing in depth. I like the response structure idea but I don't know of a full write up of the whole thing.
Is the B.U.S. System, or the stuff from HardL above good to check out?
More generally, let's attack this from the other side:
If you were starting a new partnership today and wanted a serious tournament system, what materials would you guys use? Is there something documented well enough that we could hypothetically learn it and be set in terms of modern bidding thinking? Maybe backing up from there is better than trying to navigate in.
More or less:
What is does a top tier system look like? What is a good starting spot that we can evolve in that direction? And what are the most important pieces to focus on?
In general, my, perhaps mistaken, belief is that super elaborate bidding systems only really pay off at the very elite levels where everyone's play is essentially perfect so the only marginal advantage you can get is from being much more precise with the bidding.
Maybe this problem kicks in lower than I think. But this is a new partnership and getting on the same page quickly and consistently matters. So better documentation trumps better system for now. And principles trump specialized sequences and treatments.
But we do want to know what a top tier system looks like. You always have poorly bid hands sooner or later and knowing how better players deal with it is probably a good guide for what you want to do. And we will want to make improvements. So knowing what an improvement looks like is helpful.
If people are skeptical of Meckwell lite, I can use the 1C structure from Precision today or Revision club or anything else with a solid write up.
My main issue with Revision is that I like weak NT openings and they have a super-strong one. It makes sense in contex, so maybe I should try it. It has the best write up I've found. And the logic for that strong NT is pretty solid. So maybe I'll be pleasantly surprised.
So, IDK, you guys can make a recommendation. I'll follow it.

Supposed that you are lucky enough to discover notes to Uzbek Club (which, btw, is obviously the best bidding system that has ever been developed). You still need to have a good working knowledge of Acol or 2/1 or whatever else is played locally because, if not, you're never going to fully grasp all the inferences of what your competitors are doing. So, to some extent, you're going to want to start with whatever is popular around you. (It will also be easier to find books, to find partners, etc)
As a practical example, I believe that it is much easier to learn MOSCITO than 2/1 GF.
I wouldn't recommend that people ever start with this.
If / when you decide that you want to branch out and learn some other bidding system, the important thing to understand is that there is no clear consensus about what the "best" bidding system is. It all boils down to personal preference. I strongly recommend that you look at / experiment with a variety of systems and see if you can find one that is a good match for your style. Ideally, you're going to want to be able to get to the point where you summarize the key ideas that define various bidding systems in a fairly concise way.
For example, for MOSCITO I'd say that the system is based around the following concepts:
1. It's better to have a quick and uninformative auction to an adequate contract than a slow / revealing auction looking for the "best" contract
2. The strong club opening and relays are necessary enabling tools for what we really care about (light / limited openings and a lot of constructive raises)
3. Four card majors let us bash our way to 2M / 3M / 4M ASAP

it's interesting that IMPrecision (while also a relay-based system with direct semi-positive 1♣ responses) has very different concepts:
1. Shapely hands should act aggressively in a way that unambiguously shows the long suit.
2. Accurate partscore and game bidding is very important.
3. We strive to help partner make the best possible decisions (both in competition and without) rather than attempting to conceal information from opponents.

First, you can open lighter if you want, say (9)10-15, and give your opponents more trouble while still handling the continuations tolerably via a 2/1 approach. Sure it will be more precise if you play 11-15 old style precision, but opening light can put the opponents into their much less precise competitive bidding methods more often and also lets you open a few lighter preempts as well (since for a fixed preempt range, you can shift everything down a bit since the 1 level openers are lighter, say 3-9 instead of 5-11). You could also play SAYC instead of 2/1, or even relays over your 1 level openers, but I have not been convinced these are meaningfully better approaches rather than just different, so if you’re comfortable with 2/1 I’d just go with that.
Second, you can play relays over your strong club. Which relay system you play doesn’t matter much, but getting responder’s full shape below 3N with an option to continue with honor scans if things look promising is quite valuable. There are many relay systems but again I think 90% of the benefit is playing any relay system, so pick whichever one you like and can remember. Symmetric relays like TOSR are easier to learn and remember, so that might be a good place to start. The transfers are also a nice feature.

rbforster, on 2019-September-07, 11:43, said:
I disagree with this. There are many poorly designed relay systems.
I think a strong but not unreasonably complicated system would borrow from several systems....
1C-16+ (17+ bal)
1D-2+D
1M-5+M
1N-good 13-bad 16
2C-6+C
2D-3-suited, short D
2M-weak
2N-good 19-bad 21
For the club structure, I would model after IMprecision but the semipositives would be GF and promise 5+ queen points (A=3, K=2, Q=1).
1H-any with 4+S except 4S/5+H
1S-bal or D
1N-5+H but not 5+C
2C-6+C or 4+D/5+C
2D-4+H/5+C
2H-4S/5+H
2S-3-suited short S
etc-4H/5+D
The reason i would recommend this structure is because if the opponents interfere, responder has shown the most likely useful suit feature of his hand and can continue to describe his hand naturally. Many relay systems get befuddled after interference.
awm had a suggestion slightly better than the structure above but I can't find it (maybe he can). awm will give you good advice.
You can look at the IMprecision document for how to continue patterning the hands and how to find the number of queen points and which honors responder finally holds.
Then after 1 C-1D 0-7 I would use Meckwell (or similar Meckwell Lite) continuations because relays (which are the primary alternative used by both standard symmetric and TOSR) here are doubtful because they start too high.
