Negative Doubles


quiz-pic

There is no more important convention in bridge. A negative double is made by East in this auction:

WestNorthEastSouth
 1 of a suit  Any Suit Overcall  Double  

Only the partner of the opening bidder can make a Negative Double.

What does it show? Enough to respond (the higher the level, the more the requirements). On the 1-level, it can be made with as few of 6 points. There is no upper limit. A negative double can be made with 20 or more points!

It shows the "other suits" with the focus on the other major. There are 2 specific auctions where the Negative Double comes with guarantees:

WestNorthEastSouth
 1♠ 1♠ Double  

This Negative Double guarantees both majors (at least 4♠ and at least 4♠).

WestNorthEastSouth
 1♠ (or 1♠) 1♠ Double  

This Negative Double (after a 1♠ overcall) guarantees exactly 4♠ (not 3, not 5). A 1♠ bid would guarantee 5 or more spades.

At a higher level, you might make a negative double with less perfect shape but no clear bid.

WestNorthEastSouth
 1♠ (or 1♠)  3♠  Double  

This auction guarantees at least 10+ points, but not necessarily 4 spades.
