The initial inspiration for these pages came
from the late Helge Vinje in his New Ideas In Defensive Play In Bridge.
I'd like to thank Michael Kufs for his stern
and steadfast insistence on truth and clarity.
Thanks also to my brother, Bob Sheehan, who
helped hammer out many of these ideas.
Special thanks to Marty Bergen, Ronnie Blau,
