第7副牌讨论中涉及的Wolff Signoff约定。
http://www.bridgebum.com/wolff_signoff.php
The Wolff Signoff is an artificial 3 convention used in the following auction:
Opener Responder
1-of-a-suit 1-of-a-suit
2NT* 3C! * Balanced with 18-19 points
The artificial 3C bid shows a weak hand, generally with at least five cards in responder's original suit. With three-card support, opener bids that suit at the three-level. Without three-card support, opener is required to rebid 3D, artificial. All of responder's subsequent calls over 3D are natural signoffs, with the exception of 3NT, which shows 10-12 points and support for opener's original suit. The 3NT rebid, however, is nonforcing. |
