Sixpack: Adventures with Keycards and Queecards [DeSerpa]

An innovative approach to showing Keycards and Queens as soon as a double fit is exposed.

DeSerpa recommends showing these important cards as early and as low as possible. The first section of the book sets out a basic set of principles for any partnership to adopt and Part Two gets a bit more advanced and complex.

You can apply Sixpack to your notrump structure as well as many standard suit  bidding situations.

Contains lots of example hands and four extensive quizzes for you and your favourite partner to practice this exciting new convention together.
