Jacoby Transfers
Jacoby Transfers are used after a player has opened or overcalled a natural 1NT and his partner holds at least one five-card major suit. Responder naturally wants his side to play in his long suit, but with a weak hand, he would prefer his partner to play the contract. The reasoning is fairly simple: If the weak hand plays the contract, the strong hand becomes dummy and exposes its high card points and tenaces to the defenders. If the strong hand plays the contract, however, the weak hand becomes the dummy and the opponents have a harder time determining which high cards are where.
Jacoby Transfers work as follows. In response to 1NT:
2 | Shows at least five hearts. Requires partner to bid 2 (or 3 with a great hand and great support). |
| 2 | Shows at least five spades. Requires partner to bid 2 (or 3 with a great hand and great support). |

In Competition
After 1NT is doubled or overcalled, transfers are off completely.
If the artificial transfer bid is doubled, the 1NT bidder can pass with only two-card support, redouble to show a good holding in the artificial transfer suit, or complete the transfer by bidding 2 or 2 with at least three-card support.
If the artificial transfer bid is overcalled, the 1NT bidder can pass with only two-card support, double for penalty or complete the transfer at the three-level with at least three-card support and a very good hand.
Extra Tips
- Jacoby Transfers are also used after an opening bid of 2NT or 3NT, as well
as strong notrump rebids by an opening 2 (artificial and strong)
bid.
| 2NT | : | 3/3 |
|
| 3NT | : | 4/4 |
|
| 2 | : | 2 |
| 2NT | : | 4/4 |
|
| 2 | : | 2 |
| 3NT | : | 4/4 |
Note that Stayman, not transfers, should be used with hands that are 4-5 or 5-4 in the majors.
Beginners are prone to forget transfers when they come up, resulting in some very unhappy contracts. If you are a novice and decide to use transfer bids, be sure to remember them when they come up.
