A Beginner's Guide to the Stayman Convention

Your partner opens 1NT and you hold ♠ K J 7 4 ♥ Q 9 3 ♦ 8 5 ♣ K J 4 2. There is a game in this hand if you can find a major-suit fit, but bidding 2♥ yourself would not promise the four cards you actually hold — and the responses to 1NT are already reserved for other jobs. Stayman exists to solve precisely this problem. It is usually the first convention a new player learns, and for good reason: it turns up on perhaps one board in five.

What the Stayman convention does

A 2♣ response to partner's 1NT opening is artificial. It says nothing whatsoever about clubs. Instead it asks one straightforward question: partner, do you have a four-card major? Opener answers truthfully, and between you, you either find a major-suit fit or discover there isn't one and settle somewhere sensible in no-trumps.

The convention is named after Sam Stayman, the American international who popularised it. It has been standard practice for decades, which is a good sign: it is easy to remember, it works, and you will meet it at every club you visit.

When to use Stayman

As a rough guide, use Stayman when all of the following are true:

• You hold at least one four-card major. Both majors is even better, because it doubles your chances of finding a fit.
• You have game interest. Facing a weak 1NT (12–14 points), that means roughly 8 points or more. If you play a strong 1NT (15–17), adjust the numbers accordingly — the principle is the same.
• You do not hold a five-card major. With five hearts or five spades, use a transfer instead, then show the fifth card later. Stayman is for four-card suits.
• The opponents have stayed quiet. If they double or overcall your 1NT, most partnerships switch to a different set of agreements. Discuss that with your regular partner rather than guessing at the table.

One exception you will hear about is the weak, or "garbage", Stayman: bidding 2♣ with a poor hand and both majors, intending to pass whatever opener says. It is a genuine improvement in some partnerships, but it needs an agreement and a little practice. Do not assume it without one.

Opener's three replies

Opener's answer is simple and disciplined. There are only three bids, and none of them promises extra strength:

• 2♦ — no four-card major. This is the most common reply.
• 2♥ — four hearts, and possibly four spades as well.
• 2♠ — four spades, but denies four hearts.

The order matters. With four cards in both majors, opener always bids hearts first, because responder can still show spades afterwards. A 2♠ reply, by contrast, tells partner that hearts are not in the picture — which is exactly the information needed to choose the right contract.

What responder does next

After the reply, you know whether you have a fit. Now decide the level.

If you have found a fit

With a fit and a minimum hand, raise to the three level — that is invitational. With a better hand, bid game. Holding ♠ K J 7 4 ♥ Q 9 3 ♦ 8 5 ♣ K J 4 2 opposite a 12–14 1NT, if partner replies 2♥ you can raise to 4♥ directly: the fit, the extra trump and the useful king all argue for it. If partner replies 2♦, your side has no fit, and 3NT is the sensible target.

If you have not found a fit

Without a major fit, the question becomes whether the combined hands can make 3NT. With around 8 or 9 points, invite with 2NT. With 10 or more, jump to 3NT. And if opener replies 2♥ but you actually hold five spades, bidding 2♠ now describes that shape — a useful gadget, and worth agreeing with partner.

Four mistakes beginners make

First, using Stayman with a five-card major. That wastes the convention and often buries a nine-card fit. Second, treating 2♣ as natural and passing it because you happen to hold clubs — it is artificial, and passing will usually end badly. Third, forgetting that Stayman says nothing about strength beyond "I have game interest": a 2♣ bid does not promise clubs, length, or a big hand. Fourth, guessing after the opponents interfere. Agree beforehand whether a double of 2♣ means something, and whether you play systems on or off.

Practical points at the table

Under EBU regulations the 2♣ response is announced rather than alerted: opener says the word "Stayman" when partner bids it, and that is all. No explanation is needed at the table unless an opponent asks.

A simple memory aid: two clubs asks the question, two diamonds says no. Everything else follows from opener's reply and the strength of your own hand. If you can recall those two facts, you can play Stayman competently this evening.

One more habit worth building: before each session, spend thirty seconds confirming with your partner what 1NT shows, whether you play transfers, and what happens if an opponent doubles. Most bidding disasters in club bridge come from misunderstandings about simple agreements, not from complicated ones.

Putting it into practice

Play Stayman on the next three or four hands where it applies, and talk through the auctions afterwards — particularly the ones where you ended in 2NT or 3NT rather than a major. Stayman rewards a little repetition. Once the three replies are automatic, you will start to see the game it wins: the 4–4 major fit that plays a trick better than no-trumps, and the confident 3NT that would otherwise have limped to an invitation. Add it to your card, tell your partner you are using it, and enjoy the extra boards it brings your way.
