7 ). doubled
A so called negative double indicates 4-cards in the unbid Majors, which is what you have. In this case the unbid Major is Hearts. Rather than call 2 Hearts, which promises a 5-card Heart suit and 10 HCP, neither of which are true, you could either pass or double. You have also kept the bidding low, so your partner can for example rebid clubs without going up to 3.

2 . 1 Spade
A so called negative double indicates 4-cards in the unbid Majors. In this case the unbid Major is Spade, although it's a 5-card suit. You could call 1 Spade, or you could double. In this case, with 5-cards, bid the 1 Spade, giving your partner a length count.

You opened 1 Club. Your LHO overcalled with 1 Spade and your partner immediately doubled.
Answer
Which suits does your partner have, how many cards in each case, and what is the range of points in his hand ?
5 . Hearts, 4+ card, 6-15 points
A negative double only means two suits when two minors or two Majors have been bid. Otherwise it only promises the missing Major. In this case, your partner wanted to bid 1H, and would have done so had there been no overcall. Therefore his hand promises the same as that bid would have done, namely 4-cards and 6-15 HCP. You are merely promising 6 HCP, since the overcallers bid is in effect "transparent".

Answer
Which suit does your partner have, how many cards in each case, and what is the range of points in his hand ?
9 . Spades, 4 card, 6-15 points
Your partner cannot have a 5-card Spade suit, or he would have bid 1 Spade in this case, assuming he is aware of the use of the negative double bid to tell partner only 4 cards ! In this case, doubling promises exactly 4 Spades, not 5. Also, he could have less than 10 HCP, since without the overcall there is no need to go to the two level.

You have both of the unbid Majors, as in the hand for Quiz B.0123 question 6. But this time you two 4-card suits, instead of a bidable 5-card suit. You can tell your partner this with a "negative double", given that you have enough points.

9 . doubled
You should NOT change to a new suit at the two level with only 8 HCP unless you have exceptional length. So that's not on. But you have both of the unbid Majors. A "negative double" after two minors tells your partner that you have at least 4-cards in the missing Majors, and some values to bid. 8 points is fine, as it would have been enough to reply in either Major at the one level.

3 . 10, I have 4 Hearts
If the enemy had not interfered, you would need 10 points and 5 cards to bid a Major at the two level. Your "negative double" implies 10 HCP, although it only promises 4 cards.

6 . doubled
When two suits have been bid and they are BOTH Majors, then a negative double promises two 4-card minors and 8+ points, which is just what you have. This is somewhat more descriptive and useful than a bid of 1NT.

(of 12 on this page)
You are South on the table shown to the side. Both sides are vulnerable. You opened 1 Club, your longest suit, which was overcalled by West with a 1 Spade overall. Your partner doubled, showing the missing Major (Hearts) and at least 6 HCP. East passed.
What should you bid, with your 15 HCP ?1. pass
2. 2 Clubs
3. 2 Hearts
4. 2 Spades

You are South on the table shown to the side. Both sides are vulnerable. You opened 1 Club, your longest suit, which was overcalled by West with a 1 Spade overall. Your partner doubled, showing the missing Major (Hearts) and at least 6 HCP. East passed.
Answer
What should you bid, with your 15 HCP ?
1 . pass
In this case you can pass for penalties. You can see that West is in trouble with his Spade bid. Although he has 5 of them, yours are probably better even if he has all the missing ones (Q J 9 x x). And you have all the other suits covered, assuming you can use the odd trump to limit their diamonds if your partner has no stoppers. Any bid of NT is very unsafe for you, with the singleton Dlamond, as you'll probably lose 5 straight off, and you can't be sure of not having the odd Heart loser.

- Question 12
(of 12 on this page)
You opened 1 Club, which was overcalled with a 1NT.
Your partner doubled. What does he mean, after the NT bid ?1. Double for penalties
2. I've got some points, but not enough to bid at the two-level
3. I've got some points, say 8+, and depending on what you've got they could be in trouble with their 1NT overcall. Pass if it's the later, otherwise keep bidding

In a way, all three possible answers are true. Read about this on the page that deals with doubling a NT overcall, page 124.
