This is a convention that uses a 2NT response to 1-of-a-major as artificial – showing support and a strong hand. It is a useful addition to your armoury which can help you find some good slams. This module gives you a chance to see the convention and how it works and then to see examples of the convention in action.
The course has a set of live seminars on the topic and then a few hands of the week to see it in action.
