The first article on the 2/1 system was written several years ago, but still seems like a good starting point.

Candy Griffey remarked the other day that too many of the beginning classes teach bridge that must be discarded as soon as you graduate from tadpole to minnow.  At tournaments these days almost everyone plays some form of a 2/1 system and a forcing (or semi-forcing notrump).  It isn't that difficult; in fact, I think it is easier than trying to bid playing "Goren" or whatever people call non 2/1 methods.

2/1 means many things.  Some like to say "we play 2/1 with gadgets."  That just means they play a relatively modern system which includes a game-forcing 2/1 bid, a forcing or semi-forcing notrump and any number of other conventions, e.g. 4-suit transfers over 1NT; Bergen raises; Drury; Inverted Minors, etc. etc.

For the next few months I will be writing on this subject.  My first objective is to cover the actual 2/1 bid itself along with a forcing notrump. The one thing you must play if adapting a 2/1 system is forcing or semi-forcing notrump.  Most of the other stuff (like Bergen, Drury, etc.) really has nothing to do with 2/1 per se and is optional.

I have asked Larry Griffey and Candy Griffey to contribute and may ask others. The purpose is to encourage interested developing players to adopt a 2/1 structure and to give more experienced players something to think about as
well.

There is quite a bit to cover.  Also, it will do more harm than good if you don't really understand what you are playing or try to do too much too soon.  On the other hand, an effective, active bidding style can cover a lot of errors in play and defense.  I will also be glad to refer you to some other material.

And I think our web site has ways that you can ask questions via email.  That might be helpful.

It's been awhile since the last 2/1 article, but let's get started.  If you are serious about learning 2/1,  I would recommend that you visit Bernie Chazen's website (www.berniechazen.com).  For just signing up on his mailing list you get access to his booklet "The Logic of 2/1 vs. Standard."  The booklet explains why 2/1 is superior to "Standard" and gives some principles of 2/1.  It isn't all easy reading, but it is fairly succinct (26 pages) and well written.  If you want to spend some money ($19.95) you can sign up for Bernie's monthly publication, "Bridge Sense" and all the other things Bernie offers.  He is a great teacher, and it is well worth the money, but you can get the 2/1 booklet for free.

There aren't any great books out there about 2/1 (that I'm aware of).  Mike Lawrence has a program on a CD Rom that is pretty good.  Marty Bergen wrote some articles many years ago about 2/1.  I like Marty's approach.  What I'm saying is that there are many differences in the details of various 2/1 systems.  I'll tell you what I like with no further caveats about the different methods available.  The important thing is that you and your partner are on the same wavelength.

Introduction

 "Two over one" is the name commonly given to any modem bridge system that incorporates a non-jump, non-passed hand, two-level response to a one-level opening as a game force.  For example,

 1- Pass- 2♣     1♠- Pass- 2    1- Pass- 2♣   

are all examples of game-forcing two over one (2/1) auctions.  This feature is just a part of a modern system, and most players employ a system known as      TWO OVER ONE WITH GADGETS.

The basis of these systems is usually the game-forcing 2/1 bid, a forcing or semi-forcing 1NT response to one of a major, Limit (or Bergen) raises, inverted minors, Checkback Stayman (or 2C Checkback), 4th suit forcing, etc.  It sounds foreboding, but it doesn't have to be....   Read more
