1. What do you need to double when one opponent has opened and the other has responded 1NT?
2. Does it make a difference what suit was opened?
Of all the parts of this series on takeout doubles, one of the easiest involves what to do when an opponent opens one of a suit and his partner responds 1NT.
Assume that they are using a natural system: a minor-suit opener promises three cards, a major promises five. Also assume that no one is vulnerable.
First we will deal with a 1♣ opener.
You should be aware that some partnerships agree that a 1NT response to 1♣ shows 8–10 high-card points. This does not make much difference, although if you have a minimum takeout double, you might choose not to bid.
Here are some hands that South might have. What should South do with these hands in the given auction?.
West, remember, opened 1♣, and East bid 1NT. For purposes of this quiz, assume East has 8–10 points and no four-card major.
