The Useful Space Principle, or USP, was first articulated in a series of six articles in The Bridge World, from November 1980 through April 1981. (The International Bridge Press Association awarded its 1981/1982 award for Best Article or Series on a System or Convention to Jeff Rubens for this series.) The USP is expressed succinctly in The Bridge World glossary as: "a partnership's assigning meanings to actions so that the remaining bidding space matches the needs of the auction."
The articles on the USP were the genesis of widely used conventional methods such as Kickback and transfer advances of overcalls. The USP tells bidding theorists that bidding space should be allocated where it is most needed.

Famous quotes containing the words space and/or principle:
“Though seas and land be ‘twixt us both,
Our faith and troth,
Like separated souls,
All time and space controls:
Above the highest sphere we meet
Unseen, unknown, and greet as angels greet.”

“If there be one principle more deeply rooted than any other in the mind of every American, it is that we should have nothing to do with conquest.”
