You may be either Opener or Responder, but you will always be in the South position.

The first page or two of each Deal shows only your hand. The initial bidding is given and you are asked to decide what you would bid, then click BID. The subsequent page will then appear telling you what you should have bid and continuing the auction. On the final page of each Deal partner's hand will be shown.

Feel free to disagree with some of the bids that do not apply directly to Transfers. Deals 9 and 21 for example.

Although it is not included in the Deals you might wish to examine your and dummy's hand and make a Plan of how you would play the contract.


Created by Oswald Jacoby a lot of years ago, there are two good reasons to use Transfers.
  1. They provide a precise bidding method when the Responder to a 1NT opening has a 5 or 6 card Major suit.
  2. They make the opening 1NT hand the declarer, keeping the stronger hand concealed.
Jacoby Transfers should only be used in conjunction with the Stayman Convention. The two work smoothly together with Stayman taking care of those hands where Responder has a 4-card Major(s) and Jacoby Transfers taking care of those hands where Responder has a 5- or 6-card Major.

The actual working of transfer bids is simple:
After a 1NT opening a 2 response requires Opener to bid 2, while a 2 response requires Opener to bid 2♠.
On his next bid Responder clarifies the picture by either placing the contract or by inviting Opener to do so.

Jacoby Transfers take much of the guesswork (sometimes called judgement) out of the bidding and steer you directly to these two goals:
  1. With a partnership 26 points you will reach game, with 33 you will reach slam.
  2. With a partnership 8+ cards in a Major suit you will play in that suit, otherwise you will play notrump.
For the first point consider this table which is based on the 1NT opener holding 15-17 points.

Opener PointsBidding

Responder's actions are as follows: Opener's actions are as follows: As to the second point above (the 8-card trump fit) you must keep in mind that it is correct to open 1NT with 5-3-3-2 distribution, so it is possible for Opener to have a doubleton in the Major suit that Responder is interested in. Therefore Responder must bid differently with a 5-card suit than he does with a 6-card suit. Opener also has to keep on the right track when Responder has shown only 5 of the suit by rebidding notrump. Some comments are in order about the point count methods used on these pages.
