Dear Mr. Wolff:

Recently, I opened one diamond with ♠ Q-6, ♥ J-3, ♦ A-J-7-4-2, ♣ A-K-J-9, and I heard my left-hand opponent overcall one spade. When my partner doubled, I was not sure at what level to bid clubs, or whether to gamble on one no-trump. My partner told me later that a jump to three clubs would not be forcing here. Is that true? I thought opener’s jumps in new suits were forcing.

— Shaking Stephen, Elkhart, Ind.

ANSWER: You must differenti­ate between an unconteste­d sequence — where your jump rebid of three clubs would be forcing — and a jump in response to a negative double. Think of the latter sequence as jump raising a suit partner has implied. Having not opened one no-trump (well done!), a jump to three clubs shows this hand nicely.

Dear Mr. Wolff:

If you open one club and hear a one-spade call to your left and two hearts from your partner, what should you do next with ♠ A-Q-3-2, ♥ Q-5-3, ♦ K-10, ♣ J-9-42?

— Second Chance, Winston-salem, N.C.

ANSWER: You can raise to three hearts, natural and non-forcing, or you can rebid two no-trump to protect all your tenaces while also limiting your hand. I think the latter is better; you can always support your partner later on.

Dear Mr. Wolff:

What is the main difference between the meanings of your calls in direct and balancing seat? Is it always about high-card ranges, or are there positions in which bids have different meanings?

— Protection­ist, Lorain, Ohio

ANSWER: When you are in the balancing or protecting seat, you tend to reopen when possible, so your actions may be made with about a king less than they guarantee in direct seat. In that seat, jumps over one-level bids, however, are 13-16, not weak, with good suits. And a jump to two no-trump would be strong, not unusual, with a range of 18-20 or so.

Dear Mr. Wolff:

What are the merits and drawbacks of third-andfifth leads, and why should I consider playing them?

— Pippy Longstocki­ng, San Juan, Puerto Rico

ANSWER: Third-and-fifth leads may help you work out how long partner’s suit is. Fourth-highest and second from bad suits may help you differenti­ate when the lead is from an honor or from weakness. The two-card disparity of a low card being from three or five cards (as opposed to the one-card disparity of fourth from four or five cards) is what may help you out here. But if you lead count cards, your partner will often have no idea how good your suit is.

Dear Mr. Wolff:

I’m not sure whether I’m supposed to compete facing a negative double with extra shape but no extra high cards. I held ♠ Q-J-9-4-2, ♥ A-Q-3-2, ♦ 5-3, ♣ K-10 and opened one spade. When the next hand overcalled two diamonds, my partner doubled. The next hand raised to three diamonds. Should I bid three hearts now, or wait for my partner to double and then show my suit?

— Raising the Roof, Seneca, S.C.

ANSWER: You would have bid two hearts gladly in a non-competitiv­e auction, which means you are allowed to compete to three hearts here. With, for example, 16 points or more and 5-4, you would bid four hearts here, so the problem is what to do with slight extras. There is no good answer other than to guess well.
