Wolff Signoff
A method devised by Mr. Bobby Wolff and permits the responder to stop the auction at the three level, after the opener has made a jump rebid of 2 No Trump. The auction below should clarify the particular auctions:

Opener		Responder		Meaning
1		1 / 1 / 1
2 NT				18-19 points
or
1		1 / 1
2 NT				18-19 points
or
1		1
2 NT				18-19 points
or
1		1 NT
2 NT				18-19 points
or

2 NT				18-19 points

Responses:

1. The responder bids 3 Clubs to request the opener to bid three of the responder’s first suit, if he has a 3-card support. If not, then the opener should rebid 3 Diamonds. The artificial 3 Clubs bid shows a weak hand, generally with at least five cards in responder's original suit. All of responder's subsequent calls over 3 Diamonds are natural signoffs;

2. the responder can then stop the auction by passing, or keep the auction alive by bidding 4 Clubs or by introducing another suit of lower rank than his first bid suit;

3. a rebid thereafter, if possible, of 3 No Trump by the opener is considered a slam attempt in Clubs.

The Wolff Signoff can also be used by the responder as a second bid in the ACOL bidding system.

This method should not be confused with the Checkback Stayman convention.
