Negative Slam Double
- A Double of opponent's slam used to indicate either a willingness to
continue bidding or penalize the opponents (various treatments are
available, including the negative and positive slam Double).
Example:
(1H) - 2S - (4H) - 4S;
(6H) - X
This Double indicates the
player has no defensive tricks and, assuming partner's hand is limited to
offensive values , suggests partner make a sacrifice slam bid (usually with favorable vulnerability).
