The basis for the system described in this book was first suggested by Marshall Miles in My System: the Unbalanced Diamond (Master Point Press, 2007). The core of SCUD is the same as in Miles' book; that is, strong club, unbalanced diamond, five-card majors and a weak notrump. However, author Bruce Watson felt that the original treatments for the Two Club and Two Diamond openings needed to change. In addition, he wanted to use transfer responses to the strong club but retain the negative One Diamond response. And the end product had to comply with the Open Chart of the ACBL, so it could be played in all but restricted games.

SCUD will appeal to any partnership interested in learning a very effective bidding system that is fun to play. Or, whether you currently favor a strong club or a more natural approach, you may find a treatment in SCUD that you can graft on to your favorite system.
