Forcing Notrump - A conventional response of 1 Notrump to
partner's major suit opening, requiring further description of opener's
hand. Originally created by Alvin Roth and Tobias Stone and later
adapted by Edgar Kaplan and Alfred Sheinwold in their systems, the Forcing Notrump
call is a cornerstone of the 2/1 system.
The Forcing Notrump shows a range of 6-12 points. This treatment is necessary to cover
Responder's 10-12 point range, where a two-level bid by responder creates a
game forcing response.
