negative doubles

[efe_]

hello friends

 

can anyone show me a document or web-link which explains negative - t/o doubles with details.. google has some basic rules, 1c 1s x etc..

I like to learn experts' general aproach of negative doubles in advanced sequence and higher openings. how can I understand which double is penalty which one is neg and whic one is optional?

thanks all

I was going to say a book could easily be filled discussing this topic, but I think I was wrong...it would take several books. I don't even know how to give general rules on this, but here are a few, keeping in mind a negative double is 1x by partner, and then an overcall of something on your right.

 

1) If ONE major is unbid, a negative double shows 4+ cards in the unbid major (except 1m 1H X which shows EXACTLY 4 spades). If you have more than 5+ cards in the unbid major and choose to make a negative double, you have less than enough values to bid that suit at the lowest level (less than 10 if thats the 2 level, less than a good 11 if thats the 3 level).

 

2) Over 1C 1D, a negative double shows 4 cards in BOTH unbid majors.

 

3) Other than 1C 1D, if TWO majors are unbid, a negative double promises 4 cards in at least ONE unbid major. However, if you don't have both majors, you have support for partner's minor so that you can correct back to it if partner bids the wrong major.

 

4) Negative doubles at the 1 level show about 6+ points, at the 2 level about 8+ points, at the 3 level about 10+ points.

 

5) If both majors are bid, a negative double shows both minors

 

6) A negative double is NOT made with support for partner's major, but should be made with support for partner's minor. Majors first.

 

7) You should play negative doubles through at least 4D.

 

8) All of what I said has many exceptions, and are just very basic guidelines.

ty Justin,

 

One of my partner told me a basic rule about distinction of negative/penalty doubles.. acording to rule:

 

1) if our both hand are not limited yet, x by us : negative (partner can make it penalty)

 

2) if our both hand are limited, x by us : penalty

 

3) if one hand is limited and the other player's hand is not limited yet, x by us is optional.

 

this rule considers hcp's

 

these days duplicate bridge is developed too much.. experts use neg doubles almost in every auction.. most of us play 2/1 and dont know how can penalise opps' aggresive overcall..

 

fo example: what is x here>> 1♠ p 2♣ 2♦ DBL

I think it is penalty but what is the rule? May be no one knows :)

Modern Bridge Conventions by Root and Pavlicek (1981) on pages 110 to 131 is one of the few books that definitively goes through a complete, not-too-complex set of rules so that you know which doubles are take-out and which are penalty. Especially on pages 117 to 125.

 

Both authors are excellent bridge writers, right up there with Reese, Lall and Lawrence as the best bridge writers ever, in my opinion. The only problem with the book is that it is 28 years old so it is no longer modern, due to major changes in competitive bidding in recent years. I'm just guessing - perhaps Richard Pavlicek's website might have more up-to-date information?

Hi,

 

have a look at "Partnership Bidding in Bridge" by Robson / Segal,

a PDF download, as far as I know authoriszed can be found here

http://bridgewithdan.com/systems/Partnersh...ingAtBridge.ZIP

 

Another option is "Competitive bidding in the 21th centrury" by Marshall

Miles.

 

As a general rule: I would not make a big difference between neg. X

and T/O X, basically they are the same, the only difference is, that

T/O doubles show up in different scenarios, and peoble gave those T/O

doubles different names.

 

And there is also at least one book by Lawrence about take out doubles,

not sure how extensivly he treats neg. X.

 

With kind regards

The Complete Book of Takeout Doubles doesn't cover negative doubles at all - it's entirely about doubles by the defending side.

 

Contested Auctions is about auctions where our side opens the bidding, and it includes over 100 pages on dealing with a simple overcall.

 

Double! New Meanings for an Old Bid has a less extensive section on negative doubles.

Marty Bergen also has a small book devoted entirely to Negative Doubles.

This might help some people, but maybe a bit basic

There is some interesting other stuff in Mr Bridge's library

I liked:

 

Negative and Responsive Doubles in Bridge by Harold Feldheim

 

I think it is out of print, but they seem to have a copy at

 

Biblion.co.uk

 

From the same author I found a larger book at amazon.com.

Are there any good books showing lots of examples after later round negative/action doubles? e.g. responder negative doubles or makes a forcing free bid, advancer jump raises to 3 or 4, either opener or responder doubles.

 

I know basically these say "I have extra values, but don't know what to do, do something", but as the other side to this I often don't know what to do either! What hands should be included/excluded in these 2nd round doubles? What kind of hands should you pass the double with? When the opps have gone a bit crazy and you really want to axe them and bar partner, you can't stop him from taking out on his void when you have KJTx trumps, how do you avoid accidents here? Are there any auctions where double is clearly penalty anymore?

 

Sometimes I think it was easier when more of these late doubles were just penalties, get what we can on defense.

Me too.
