Bidding Systems by Levels & ACBL Convention Cards

Here are the details of the AiB 2/1 Game Forcing Systems by Level.  These levels were developed from our experience playing with students of varied experience.  The agreements listed below are what we have experienced that our students learn at different points in their development (and what we have recommended to them).  For each of the 10 levels that are detailed in the sheet below, we also have the ACBL convention cards available.

 From our experience, the approximate experience level of players who employ most of each system is as follows:

  1. Getting Started (Red) - 0-5 Masterpoints - Convention Card

  2. Introduction (Pink) - 0-5 Masterpoints - Convention Card

  3. Basic 2/1 Game Forcing (Orange) -- 5-50 MP - Convention Card

  4. Improver 2/1 Game Forcing (Yellow) - 50-100 MP - Convention Card

  5. Intermediate 2/1 Game Forcing (Green) -- 100-250M - Convention Card

  6. Advanced 2/1 (Light Green) - 250-500M - Convention Card

  7. Modern 2/1 Game Forcing (Blue) -- 300-1000 MP - Convention Card

  8. Sophisticated 2/1 Game Forcing (Light Blue) -- 750-2000 MP - Convention Card

  9. Complex 2/1 Game Forcing (Purple) -- 2000+ MP - Convention Card

  10. Expert 2/1 Game Forcing (Light Purple) -- 5000+ MP - Convention Card

*The Masterpoint ranges listed above are approximate levels of experience at which our students adopt these bidding levels.  But each player's development varies, and certainly it is not expected that one will learn an entire level of bidding concepts or conventions all at once. 

System Upgrade Spreadsheet

The spreadsheet below is a more detailed "blow up" of the ACBL convention card.  Each column (color coded) contains a level of the six 2/1 GF systems.  Each row of the spreadsheet contains a collection of affiliated concepts.   The concepts and agreements are grouped together by level to help give you an idea of what to learn next.  This should help give you a curriculum to work though as you are developing your game and partnership agreements.
