Stayman Convention

Stayman

The Stayman convention is used to find a 4-4 major fit after a 1NT or 2NT opening. With two balanced hands, 3NT is often the best contract - but not always! If your side has an 8 card heart fit or an 8 card spade fit then 4 or 4♠ might be better.

Responder asks opener for a 4-card major by bidding 2♣.

Opener
1NT
Responder
2♣ - Stayman, do you have a 4 card major?
Opener
2 - No, I do not have a 4 card major
2 - Yes, I have a 4 card heart suit
2♠ - Yes, I have a 4 card spade suit

How to use Stayman

After a 1NT opening, there is no way that responder can bid naturally to show a four card suit. If responder bids a suit at the 2 or 3 level that shows a 5 card suit, not a 4 card suit.

Instead of using a 2♣ response to 1NT to show clubs, you can change the meaning of 2♣ to Stayman, asking if partner has a 4 card major.

Most of the following examples are based on an Acol, 12-14 1NT opening. The same principles apply if you're playing Standard, 15-17 1NT, but the point counts will need to be adjusted.

You find a major fit

Stayman Convention in Bridge

South bids 2♣ to see if North has a 4 card major. North says yes! - I do. Now South can bid 4♠.

You don't find a major fit

Stayman Convention in Bridge

This time the opener has denied a 4 card major. Responder simply bids 3NT now, knowing there is no major fit.

Opener shows a 4 card heart suit but that's not the major suit that responder was looking for. Responder bids 3NT.

Stayman for Acol players

In this first example below, North and South are playing Acol so the 1NT opening shows 12-points. South has enough points to bid game but 3NT will go down because the opposition can take four heart tricks and a diamond. However, 4♠ will make with careful play.

You can try playing that hand now in either 3NT or 4♠

Stayman for Standard players

Here's an example for Standard players using a 15-17 1NT opening. Try the hand in 3NT and also in 4♠

Delayed support

Here's a hand on which opener shows a 4 card heart suit and responder bids 3NT.

Stayman Convention in Bridge

Opener knows that responder wouldn't have used Stayman without at least one 4 card major. The 3NT bid shows that responder's suit was not hearts, therefore it must be spade. Opener bids 4♠ now, knowing there will be a spade fit.

Invitational bids after Stayman

In these next two examples, North and South are playing a 15-17 1NT opening.

2NT Invitation

Stayman Convention in Bridge

Opener shows a 4 card heart suit but that wasn't the suit partner was looking for. 2NT is still inviting to game, though, and shows the same number of points as a direct 1NT - 2NT bid would have shown. North is happy to accept the invitation.

Raise to 3 or 3♠

Stayman Convention in Bridge

This time North and South find a spade fit. Responder's 3♠ invites opener to bid game with a maximum hand.

Stayman after Interference - system on or system off?

If the opening 1NT bid is doubled do you still play Stayman? It's up to you and your partner to decide. Some partnerships prefer to keep 2♣ as a natural bid after the double. It's up to you, just make sure you have an agreement with your partner.

The Sky Bridge Club computer plays system off. If the opening 1NT bid is doubled then 2♣ reverts to it's natural meaning.

I can't remember is there a minimum point count to do stayman?

Thanks Graeme. I don't take it seriously enough as in working things through. Just like telling kids to think of the consequences!
