TWiB Lesson #602 (1 of 8)
There are a variety of conventional rebids that are additions to a fundamental 2/1 GF system, but there are also some fundamental response agreements that can be adjusted. One of these is the length that we promise when we respond in a minor suit at the 2-level. In the standard 2/1 system, a 2♥ response shows at least a 5-card suit, a 2♦ response shows at least a 4-card suit, and 2♣ usually shows a 4+card suit (occasionally it could be a 3-card suit).

When we choose to adopt the alternative approach to our 2/1 GF responses, 2♦ showing a 5+card suit, 2♣ being “could be short as 2 cards”, then this changes our reasonable options for rebids by the Opener. Good agreements with partner about how this approach changes our rebid agreements are vital. Let’s look at the hands that are simplified & problems created.
