Jacoby Transfers: Showing a Five-Card Major After 1NT
Jacoby transfers let responder show a five-card major after partner opens 1NT by bidding the suit just below it. Opener is forced to complete the transfer, so the strong, concealed hand becomes declarer.
How a Transfer Works
After partner opens 1NT, you bid the suit one step below your real major. With hearts you bid 2♦; with spades you bid 2♥. Opener is obliged to “complete” the transfer by bidding your major, whatever they hold.
Why go the long way round? Because it makes the 1NT opener declarer. Their strong hand stays hidden, and the opening lead comes up to it rather than through it — often worth a trick. It also gives you a second turn to describe your strength.
The Two Transfers
The rule is simple: name the suit immediately below the one you actually hold.
Transfer responses to 1NT
Note that 2♣ over 1NT is reserved for Stayman, the convention that hunts for 4-4 major fits. Transfers and Stayman work as a pair.
A Worked Example — Transfer in Action
Partner opens 1NT and you hold a weak hand with a long major:
With only 6 points this hand is not worth a game, but it plays far better in hearts than in no-trump — your five-card suit is almost useless without a trump fit. So you bid 2♦, partner dutifully bids 2♥, and you pass.
You have landed in a comfortable 2♥ partscore played by the strong hand, instead of struggling in 1NT with a useless long suit. That “weak takeout” is one of the transfer’s greatest gifts.
After the Transfer — Responder’s Second Bid
Completing the transfer is automatic; your next bid is where you set the level. It falls into three bands.
Weak, invitational, or game
Responder’s rebid after the transfer
The super-accept
Opener is not always passive. With a maximum 1NT and four-card support, opener can jump the transfer — bidding 3♥ over a 2♦ transfer, say — to announce a fit and a top-of-the-range hand. That extra information often lets responder bid a thin but excellent game.
When to Transfer — and When Not To
✓ Transfer when
- You hold a five-card or longer major
- You want the strong hand to declare
- You are weak and want a safe partscore in your suit
✗ Do not transfer when
- Your majors are only four cards — use Stayman
- You are balanced with no five-card suit — just raise no-trump
- Your partnership has not agreed transfers are on
Common Transfer Mistakes to Avoid
- Transferring with only four cards. Transfers promise a five-card suit. With 4-4 majors, use Stayman instead.
- Forgetting to complete the transfer. Opener is forced to bid the named major — passing a transfer is a classic disaster.
- Passing 1NT with a weak five-card major. A transfer to the partscore almost always beats playing 1NT with a long, trump-less suit.
- Not agreeing super-accepts. If you have not discussed the jump, opener’s 3♥ can be misread — talk it through first.
Key Takeaways
- 2♦ shows hearts, 2♥ shows spades — bid the suit below your major.
- Opener must complete the transfer; the strong hand becomes declarer.
- Your second bid sets the level: pass (weak), 2NT/3M (invite), 3NT/4M (game).
- A super-accept jump shows a maximum with four-card support.
- Transfer with a five-card major; use Stayman with only four.

Frequently Asked Questions
Transferring makes the 1NT opener the declarer. The strong, concealed hand plays the contract, so the opening lead runs up to its strength rather than through it.
A response of 2 diamonds is a transfer showing five or more hearts. It asks opener to bid 2 hearts, after which responder describes the rest of the hand.
No. You can transfer with zero points and a five-card major. The transfer only shows the suit; your next bid shows your strength, from a weak pass to a game force.
With a maximum 1NT and four-card support for responder’s major, opener can jump the transfer — for example 1NT then 3 hearts — to show the fit and a top of the range hand.
Use a transfer whenever you hold a five-card major; Stayman is for hands whose majors are only four cards long. With five-five in the majors, transfer to one and bid the other next.
Many partnerships add a 2 spades response as a transfer to a minor, but minor-suit transfers are optional and far less common than the two major transfers.
