Jacoby Transfers Over 1NT
Where Stayman asks a question, a transfer makes a statement. Bid the suit just below your real five-card major and partner is forced to bid it — landing the contract in the right strain with the strong hand hidden.
What a Transfer Achieves
When you hold a five-card major opposite partner’s 1NT opening, you already know where you want to play. A Jacoby transfer lets you say so — and does two valuable things at once. It announces a five-card (or longer) major, and it makes partner the declarer, so the strong, concealed hand takes the opening lead coming up to it rather than through it.
You bid the suit one rank below your real major. Partner has no choice but to "complete" the transfer by bidding your suit.
The Transfer Bids
Transfers Over 1NT
Notice the pattern: 2♦ is just below hearts, 2♥ is just below spades. Whatever you bid, partner bids the next suit up. Many partnerships also play 2♠ as a transfer to a minor — agree that detail before you sit down.
Completing the Picture
After partner completes the transfer, your second bid sets the level and finishes describing your hand.
Responder’s Rebid After a Transfer
A Worked Example
Partner opens 1NT and you pick up the hand below.
Just 6 points — far too weak for game — but six hearts. In plain no-trump this hand is nearly worthless; with hearts as trumps it will take several tricks. Bid 2♦, partner bids 2♥, and you pass. You have escaped 1NT into a comfortable heart partscore that rates to make.
Stayman or Transfer?
✓ Transfer when
- You hold a five-card or longer major
- You want partner to be declarer
- You are weak and want to escape 1NT into a suit
→ Use Stayman when
- You hold one or both four-card majors
- You are looking for a 4-4 fit, not a five-card suit
- You have at least invitational values
Common Transfer Mistakes
- Forgetting to complete the transfer. Opener must bid the suit above — refusing breaks the convention and strands partner.
- Transferring with only four. Transfers promise five; with a four-card major use Stayman instead.
- Passing partner’s 1NT with a long major. Even a weak hand should transfer and pass — the suit contract plays far better.
- Bidding the major directly. A natural jump to the major skips the transfer and wrong-sides the contract.
Key Takeaways
- Bid the suit one rank below your real five-card major; partner completes it.
- 2♦ shows hearts, 2♥ shows spades.
- The transfer makes the strong 1NT hand declarer, protecting it from the lead.
- Pass with a weak hand, or bid on to invite or reach game.
- Five-card major → transfer; four-card major → Stayman.

Frequently Asked Questions
A Jacoby transfer is a response to 1NT where you bid the suit just below your real five-card major. Partner must bid your major, so the strong hand becomes declarer.

No. You can transfer with a weak hand and simply pass, just to play a better partscore in your long suit. You only bid on after the transfer if you have invitational or game values.
Transfer with a five-card or longer major. Use Stayman when you hold one or both four-card majors and are hunting for a 4-4 fit.
Transfer as normal, then with extra strength bid three of the major to show six and invite game, or jump to game directly with enough points.
