After balanced 1NT,there is a new designed convention,called as Wrangler.How about it? Welcome for any opinions,Thank you in advance.

 

[(1NT)     balanced hand,weak or strong;

?     2:both minor suits with equivalent 5/4 or above,suitable HCPs;

      2:one major suit with 6cards or above,suitable HCPs;

      2:both major suits with equivalent 5/4 or above,suitable HCPs;

      2:one minor suit with 6cards or above,suitable HCPs;

      2NT:one weak suit with 7cards or above;Or strong balanced hand,similar to Comic NT;

      dbl:very stong hand with any shape;

      3Y:three suiter hand with enough HCPs,Y is the short;

      4Y/5Y:rapidly preempts with necessary

 

If the responder passes,the advancer can select their fit by P/C after 2/2; Or

try the lower suit,then decide by her/his PD after 2/2/3;Or

natural bid.As below:

 

[(1NT)/2/pass/?]

     pass:weak;

     raise:support with suitable HCPs;

     2:select with weak hand;

     3/4/5:select with suitable HCPs;

     others:natural with suitable HCPs;

IMO,the 2 suiter is most based on equivalent,in the length and strength of both suits.Otherwise, I think it's better to regard as one suit,then another if there is another chance.

 

Or the further modification for un-equivalent 2 suiter or only one suiter hand is:

 

[(1NT)

     2D:one suit of major,or a better major with another suit;

     2S:one suit of minor,or a better minor with another suit;

No offense, but I just don't like it. Dunno what you think the advantages are, but I don't see (m)any. :)

 

Some thoughts:

- against weak NT you have other design goals than against strong NT for optimal results. Any meta-system isn't optimal in one or both cases.

- being able to show a minor 2-suiter with 2 is quite useless imo. You don't take bidding space away at first, and by the time your partner can heavily support your LHO has already told something about his hand...

- not being able to show M-m 2-suiters is a heavy loss! There are 6 2-suiters, and you can only show 2 (both M, both m). For constructive purposes you need to be able to bid your Major suits, because that's one of the biggest possibilities of finding a game. Combined with the point above, wouldn't it be more interesting to use 2 for M-m 2-suiters? Or swap 2 and 2, and make it some form of Wilkozs 2, and 2 singlesuited in a Major (perhaps you can also include ).

- when preempting, you should try to bid NF as much as possible, to put more pressure. Especially against NT bidders, since your LHO expects his partner to pass if he doesn't come up. Therefor I'd advise you to play your 3-suiters as NF, so bid your suit above the singleton/void (3 shows short s).

Thank you very much,Free.Thank you for your detail proposals.

 

IMO,the main advantages of Wrangler over other method are:

(1),naturally understandable,needs little of memory;

(2),almost any hand shape would be well descriptive;

(3),"suitable HCPs" would be alterable for special NT ranges;

(4),avoid to be very afflictive to defense 1NT with some shape and strength.

 

As mentioning "offense",there are many alternatives according to the aggressiver's will and her/his hand. You know,there is an advancer there!

 

-not being able to show M-m 2-suiters is a heavy loss! There are 6 2-suiters, and you can only show 2 (both M, both m). For constructive purposes you need to be able to bid your Major suits, because that's one of the biggest possibilities of finding a game.

 

With "CRASH",there are 4 2-suiters to indirect description.but all of other shapes(4 one-suiters, 2 2-suters and 4 3-suiters;and balanced hands) can be direct showed. If it were a loss,it would be a light one.

 

If you have enough HCPs,good shape hands and good fit,there always are games.Game is not dependent to "majors".

 

As I know,when opps open 1NT(especial strong NT),the competitor seldom have a game.AT most,there is a part contract, only for good competitors.

I agree with all four of Frederick's objections. Further:

 

5) I really want natural 2M over 1NT. In general, I prefer non-forcing interference over their strong openings.

 

Regarding your advantages:

 

(1) I don't think that this is easier than Meckwell, Lionel, Woolsey or Meyerson, to name a few.

 

(2) If you mean that any hand type can be described, then I disagree (m + M). If you mean that any bid describes the hand well then I also disagree, compared to Woolsey or Meyerson.

 

(3) I assume that players interested to play a gadget can decide for themselves with which hands they like to bid and with which hands they want to pass.

 

(4) You won't be bidding more with this method than with any of the methods I mentioned.

 

So far I haven't found anything positive to say about it, sorry. I wouldn't consider any defense to a strong NT that uses the double to show values.

I agree with Hannie. IMHO, this new overcall gadget does not show any advantage over DONT or Cappelletti (which I consider quite effective, in particular DONT).

The 2 interference is very weak: no interdictive value, and you already show both your suits. It makes easy for oppos to decide if they are in fit, or want to penalise.

Double to show values is a wasted bid.

2 either major would not be a big disadvantage, but you loose all the hands with diamonds and a major (or you have to take the push to level 3).

A 3-suiter is one of the worst hand in bridge, neither fish nor fowl. Committing to play at 3-level (even if the chances of assumed fit are obviously good) is way too risky.

 

In general, I find it more useful to make an overcall over which pard can (and most of the time will) pass. A transfer bid relieves the pressure on the responder to 1NT.

I would not be very excited at the idea of reaching a playable game after oppo has opened 1NT (strong). The frequency of such an auction is way too low to justify a bidding structure.

 

The guy who opens a strong NT is already showing 35% of the HCP in the deck.

The aim of an overcall is disturbing the opponents' auction, and ideally push them toward a wrong contract

Thank you ,Hannie and Kalvan.

 

The purpose that I post the "Wrangler" here is not to replace any other present similar conventions. Just telling you, I'll use it at some time. Seldom, a new designed convention is suitable for any players,especially for other experts players or WC players. And now,I have not make the details for this convention.Perhaps I need a poll about it.

 

As you have pointed,"The aim of an overcall is disturbing the opponents' auction, and ideally push them toward a wrong contract ";if you do sth like a blind,it'll be more dangerous.

 

Of course,how high is risk is the everyday job to a good bridge player.is it?

After reading and thinking about the posts above in real earnest, IMO,there is a great feature of the Wrangler:

 

It's very fit for further bidding if you have a fit,and it can be described with 2 direct P/C(2 & 2,Round suits) and 2 indirect P/C(2 & 2,pointed suits).So,I would call it P/C Wrangler also.

 

If you always like to take unilateral actions after their 1NT open,P/C wrangler might not be suitable for you.

 

The "P/C" here is Pass/Correction.

 

[(1NT)/?:

2 2minor

2 M(+m)

2 2Major

2 m(+M)

 

After their 1NT open,P/C Wrangler with Comic 2NT,3Y short for 3 suiter,and dbl for penalty,that's all! Is it simple enough?!

In practice,2level suit competition may be as weak as 2/3 level preemptive open;

but it should be stronger with 5-4 two-suiter.It's better to have open strength especially for 2 competition.

 

2NT:It should be strong up to strong 1NT open strength if it were strong balanced hand;(strong 1NT vs weak 1NT)

 

3Y:almost game force or preempts with 3suiter;

 

dbl:strong up the opp's open 1NT with other shapes;
