In The Netherlands, many conventional systems are used and these systems of bidding have been varied, changed, and altered to fit the need and the needs of the partnership agreement. The bridge player in The Netherlands does not entirely conform to a certain standard bidding process, but has rather a wide variety of treatments and methods in his bidding bag.

Note:The defining and explaining the content of this web page made by Mr. Anton van Uitert .

The Biedereijer treatment is one of the many partnership agreements available to the bridge player, and it must be noted that the word convention, when describing Biedermeijer, is used in its widest interpretation.

As a side note, we would like to mention that the word Biedermeijer itself refers also to a style of furnishings or interior design in German-speaking areas in the early and middle 19th century. The style generally existed as a simplification of the French Empire style usually executed in fruitwood with much use of matched veneers, with accents of ebony inlay or black paint, and often displaying architectural motifs.

The meaning of the word became also later a term for the inhabitant of the house so furnished, and eventually described a morally and politically conservative citizen, and conveyed a rather negative connotation.

The treatment relies heavily on making the first bid in the auction, and each opening bid has a definite significance. The visitor must keep in mind that Biedermeijer has several variants called the Biedermeijer Red variant, which is the most complete, the Biedermeijer Green variant, which is for the Novice player, and the Biedermeijer Blue variant.

These web pages have been preserved on this site and have been taken from the Dutch Version. These variations are in their original language of The Netherlands, but we hope to preserve this convention also on this site and hope that we can find a translator, who can assist us in the translation. In addition to these variants played in The Netherlands, variations have been devised by other countries and other partnerships. The visitor should remember that this agreement, called Biedermeijer, is essentially and primarily a partnership understanding for the opening bid. Following is a devised variation, and the information stems from Mr. Hans van Staveren, Amstelveen, The Netherlands.

2 NT: 20-21 high card points Balanced shape.

Any 1 No Trump or 2 No Trump opening allows the normal use of the Stayman convention and also the Jacoby Transfer on the Two and Three Level respectively.

Although the opening bids of 2 Hearts and/or 2 Spades do not meet the lesser requirements regarding the point count of the Acol Two Opening Bids, these two opening bids are to be considered under the same aspects with regard to the number of Quick Tricks required and the responses.

Mr. Anton van Uitert, from The Netherlands, as of October 21, 2000, has contributed the following as additional, and even perhaps better information for understanding the Biedermeier treatment. Below my personal interpretation of the Biedermeier Red basics. Not guaranteed 100% correct.

Biedermeier is not a convention, but rather a Standard System containing general agreements, much like Standard American Yellow Card or BWS in the United States, although considered by several more experienced bridge players less advanced and complete than the BWS (Bridge World Standard). Though it contains some conventional opening bids like Multi or Muiderberg, it is essentially a natural system.

So Biedermeier is more than just a system of opening bids, as it also contains a set of conventions and general guidelines about the style of bidding, such as forcing situations. The Dutch Bridge League has issued 3 variants on the system: Green, Blue and Red. The Red variant is the most advanced, the Green variant is mainly for casual and/or beginner play. The list of opening bids should be as follows, according to the Biedermeier Red variant, which is the most complete variant:



1 : 11 high card points plus Promises a 3-card Club suit.
1 : 11 high card points plus Promises a 4-card Diamond suit.
1 : 11 high card points plus Promises a 5-card Heart suit, or
    Promises a 4-4 distribution in both Major suits.
1 : 11 high card points plus Promises a 5-card Spade suit.
1 NT: 15-17 high card points Balanced shape; a 5-card Major suit is possible.

Please note that the lower and upper limit depend on individual style.



2 : Strong 2-Club opening, or
    signifies a Weak Two bid in Diamonds*
2 :   Multi-colored - individual agreements below:
    a. Weak Two Major
    b. Strong No Trump range
    c. Strong with Clubs and Diamonds**
2 : 6-10 high card points Muiderberg: 5-card Heart suit and a 4-card Minor suit
2 : 6-10 high card points Muiderberg: 5-card Spade suit and a 4-card Minor suit
2 NT: 20-22 high card points Balanced shape
3 NT:   Gambling 3 No Trump
3 any suit:   Natural
4 any suit:   Natural

*Some partnerships skip the strong Clubs and Diamonds variant.
** Some partnerships skip the Weak Two variant.
