I have a new pd for the 2004 season and I hope that for the next seasons as well. We have outlined the basics of a very simple system and I'd like to know what would you add to the system, what do you think it's very important and we are forgetting ? Do you have experience with such a system?

1c: 16+ any
1d: Precision style 11-15
1h/1s: 5+ 11-15
1N: 12-15 balanced no 5M
2c: Precision 11-15
2d: Weak 2 in a major
2h/2s: Muirderberg 5 in the major 4 in a minor (2s can be s+h)
2n: 8-11 5/4 in the minors

Over 1M we play forcing NT and 2/1 GF, a 2c 2/1 bid may be balanced without a 5 card suit to bid or game forcing with clubs.

Over 1c we bid 1d as 0-7 1h,1s,1n,2c,2d are TRANSFERS *1s balanced* and 8+
After 1c-1d 1h is a power relay 20+HCP others 16-19.

Any ideas will be considered

I have come to prefer the 2D=wilkosz, 2H=weak, 2S=weak system methodology.
Alternatively, I sometimes substitute 2H=weak 2 in a major and 2S=intermediate
both minors. Intermediate minors fills a system hole in one system I play but your mileage may vary.

Using 2N to show a narrow continuous range with both minors is clearly sub-optimal. Much better to open 3C with these hands and maximize pressure on the opponents. Also, this is a mcu more efficient use of bidding space.

All-in-all, I'd much rather be playing MOSCITO, but thats another story.

Interesting point Richard, but then what do we use 2N for ? And what do we do with our 3c preempt ? I don't want to give up a 3c preempt.
I'm sure you may have some ideas.

Hi Luis

To answer this I'd need to understand how you currently treat 3C/3D opening bids.
I am assuming that you are using 3C/3D as "standard" preempts.

I would rearrange the structure as follows:

2N = Either a "standard" 3C preempt OR
Bad 3 level preempt in Diamonds

3C = Preempt with both minors

3D = Constructive 3 level preempt with Diamonds
----------------

I see a couple major advantages to this inversion:

1. Weak with at least 5/4 in the minors is significantly more common than a "standard" 3C preempt. Using 3C as 2 suited with minors significantly improves the preemptive effect of your system without harming your constructive auctions.

2. You can now differentiate between good and bad 3 level preempts in Diamonds.

I like it, I'm going to discuss it with my pd.

Hi, Luis, I think 1N with 12-15 is too large. with balanced 12hcp hand, i think it wont hurt to pass. 2d can be played as either weak two major or balanced 22-23 hand, or 4441 17hcp hand. so 2n can be played as minor two suiter, either 0-11 or 16+. you seem forget 4441 hand within 11-15hcp. i like to open 2h with this. 2s just played as natural s preempt, but better than 2d then 2s, or minor 3 level preempt. I like 2s to be s suit, coz i think 2s has very good preempt effect while 2h not.

I usually play multi and muiderberg, but I'd advise you NOT to play 2S with possible 4 card H. It takes too much possibilities away for partner to rescue, if he can't count on just 2 suits.

I have a great continuation scheme to show exact shape after Muiderberg, but it doesn't include the 5S-4H or 5H-4S. If you want I can explain it, but it's a bit complicated at first. Once you know it, it's quite easy. You won't have problems with it I guess, because you're used to play relay systems...

Since fly has attacked the 12-15 NT range, I will stick my head in here too, but for a different reason. I don't mind the width of the 12-15 range at all. But experience has showned that 1C-positive response-1NT game force, where positive response is 8+ buts too much pressure on you. You end up with a lot of balanced 16 opposite 8's in 3NT not making. I would use something like 14-16 or 15-17 1NT and use 1D followed by 1NT for the weaker hands. This isn't a huge deal, but at least one good player AGREES WITH ME (well, I guess I really agree with him), since Eric Rodwell voice this view and liked the 14-16 NT range. See… http://www.bridgemat...com/rodwell.htm

Thus, I think you may want to reconsider your NT range....

Hehe, Ben, I read that article too and was thinking to play 14-16. But there is another problem, with 12-13hcp balanced hand, esp. short diamond, if you have to open this hand, then 1d is the only choice. one reason i like precision is that you can avoid opening short suit. I really hate to open 1d with 2 or 3 cards and min hand. so after thought for a while, i gave up and go back to 13-15nt. with 12hcp balanced hand, i simply pass. now i can raise pd's d opening happily, esp. in competition.

Do you then open all 5C4M hands 2C, no matter how bad the club suit? If so, how much trouble does this cause you?

If you go with 2C guaranteeing 6 cards, then you can play any NT range you wnat, since 1D will be super-nebulous.

BTW, looking at ccs from the Bermuda Bowl, I noticed some Precision pairs were using 2D as weak, and opening 1D with a void.

What do folks think of this?

if it is 5422, i will try 1n, if it is 5431, yes, i will open 2c. I know many top players think 2c should show 6-card, but i think that is too infrequent. the reason they can do it is that they play 2d as any short d hand, 4441,4405, or 5431. I open 4414 or 4405 hand with 2h, and those 4315 or 3415 hand with 2c. I agree that if i hold 5card broke c and 4 card Major, i will have a problem. I hate it but i hate 1d to be any 0 to 3 cards.

I follow power precision guidelines.. 2C requires 6 good clubs for me. I have opened 1D with a void.

Thanks for the very good ideas.

I think I love the 12-15 range, first of all the 24HCP games after 1c-1x are exactly what I'd like to be playing, I like agressive games and making 1/3 is a good bussiness.
The other great thing about 12-15 is that it includes 15, the magic number, so when the 15-17 NTers are playing their tighter games after for example 1N-3N we will be playing a game too after an invitational sequence and acceptance.
No playing game when the panel is surely playing it is a major liability.

hi Luis and all friends,

Glad to see the system you are discussing is almost same with my lovely precision Club variant. Just may add that 1Di opening is 4+ cards non balanced, and when 4414 distribution open 1He with 4 cards. Another useful gadget is to add in 2Di multi the hand with 5He and 4Sp and 16-18 p ( the weakest range for 1Cl)

Best regards
Rado

Updates:

:-) So far so good many good ideas

I changed the 2d/2h/2sp openings:
2d = weak 5 cards in a major and 4+ in another suit (may be both majors).
2h/2s = Weak 2's Ogust style.

I also added Rado's style to the 1d opening, always 4+ diamonds, with 4441 we open 1h. 1d is never balanced because we open 1NT with 12-15 HCP.

Any chance that I could get you to consider the Frelling 2D opening.
I think that it is theorectically stronger that the 2D opening that you are considering.

Frelling 2D = 4+ Diamonds, 4+ cards in either major
Could be 4432 but not 4441/5440

Advantages include:

2D is natural. CHO can and will frequently pass 2D. This puts much more pressure on LHO who needs to immedaitely clarify many more hand types.

2D is very frequent (including 4432 hands in the opening does wonderful things for the opening frequency)

2D is constructive: I have a nice response schedule that allows you to comfortably explore for the best part score/game.

I play like Rado does, except for the interesting multi idea. I think that its worth making 2C harder to handle to let 1D be natural instead of nebulous.

I've played 13-16 NT for years without difficulty (using 17 minimum for 1C). 12-15 should be just fine. Most of the problems with opening 1C with 16 balanced come about because of the GF positives on 8 counts. Wei originally made provision for stopping short of game when 16 opposite 8. No one uses this now, it's much easier to make positives GF, but in that case, a positive should require 9 points.

Do you have a short summary of the development after 2d since it can be 5-4,6/4,5-5 etc?
I'd like to open something with 5/4 weak hands with both majors and thus I like the current 2d structure.
I might consider Frelling I'm not sure :-) but I'm getting help here :-))

Note:

As usual, I think that MOSCITO provides some very interesting ideas on this front.
In particular, "modern" versions of the system are designed to immediately clarify semi-positives after the strong club opening.

MOSCITO uses 1C - 1S to show a double negative
1C - 1D and 1C - 2N+ show game forcing hands

All other bids show semi-positives
In turn, this allows us to support a considerably weaker "strong" club opening without completely overloading the 1D response.

Using 1H+ as an absolute game force is fine for "conservative" strong club structures, but I fear its utility is limited with modern aggressive systems.
