JACOBY TRANSFER BIDS
There are four (4) circumstances that exist wherein it is advantageous to playing Jacoby transfer bids. They are as follows:
(1) Transfer bids are used to insure the circumstance such that the player with the strong hand; i.e., the opening NT bidder, will be the declarer and, thus, the player whose hand remains concealed to the opponents. This has an added benefit such that the opponent’s opening lead will come towards any tenace, not through existing ones. Natural auctions such as: 1NT-P-2S, INT-P‑3H , or, 1NT-P‑4S, auctions which do not utilize Jacoby transfers, often result in contracts being played from the "wrong side" of the table. With Transfer bidding, however, the lead by the opponents comes into the high card holding of the NT opener instead of piercing his/her high card strength; and, with the strong hand concealed, the defense for the opponents is, thus, made that much more difficult.
(2) Transfer bids facilitate responder's task of describing two‑suited hands. Consider the following two scenarios both of which would clearly present problems absent Jacoby transfers:
(A) XX KQJXX AQXXX X
Playing Stayman without transfers, responder would be forced to bid “2C” and over a statistically
probable response of 2S would then bid 3H showing 5-pieces and forcing to game. But now, what does
he/she do if opener bids 3NT? Responder has not yet shown the Diamond holding and must guess
whether to pass 3NT or first introduce his/her second suit. Playing transfer bids, however, Responder
first transfers to Hearts by bidding “2D”, and then shows the Diamond suit at the three level. If opener
then bids 3NT, it is most probably the best contract since all of Responders information has been
shared with opener being able to process this information.
. (B) KQXXX AQXXX XX X
With two five‑card Major suit holdings and game-going values Responder can first transfer to spades,
and then jump to 4‑hearts seeking the best fit with what, at the very worst case scenario, must be at
least a 5‑3 fit in one of the Majors since the opening NT bidder can have no fewer than one doubleton.

(3) Transfers also solve the problems created by many hands with invitational strength and five‑card or six‑card Major suit holdings. Examples:
(A) AQX QXXXXX XX XX Playing transfers, responder would bid “2D” and then raise
opener’s forced 2H to 3H, inviting opener to continue to 4H with a
1NT “2D” maximum holding of 16-17 HCP’s else to pass with a minimum of
2H 3H 15 HCP's.
4H or Pass
(B) KQJXX XXX XX KXX Playing transfers, responder can bid “2H”, and then invite to game
in either NT or spades by rebidding 2NT over partner's forced
1NT “2H” response of 2S.
(4) With a five‑card Major suit holding and, game‑going values, Responder can utilize a combination of transfer bidding coupled with a NT "CHECK BACK" to confirm whether the original NT bidder had two or three cards in the forced Major suit of Responder’s choice.
KXX AQXXX KX XXX 1NT “2D”
The opening INT bidder then either passes the 3NT bid holding only 2 Hearts else corrects to 4H holding
three or four Hearts.
Jacoby transfer bidding is equally applicable over 2NT opening bids.
EX. 2NT “3H” (or) 2NT “3D” (or) 2NT “3D”
3S 4S 3H Pass 3H 3NT
One may choose to utilize "Two‑way Jacoby Transfers", "Three‑way Jacoby Transfers" or "Four-way Jacoby Transfers". It is simply by partnership understanding and mutual agreement.
a) 2‑Way Jacoby Transfers b) 3‑Way Jacoby Transfers c) 4‑Way Jacoby Transfers
"2D" = Hearts "2D" = Hearts "2D" = Hearts
"2H" = Spades "2H" = Spades "2H" = Spades
"2S" = “Minor Suit "2S" = Clubs
Stayman”(Preference) "3C" = Diamonds
NOTES: 1. The way to handle a 6‑4 Major suit holding using both Stayman and Jacoby Transfers:
AXXXXX KQXX AX X INT “2C” AXXX AQXXXX X XX 1NT “2C”
“2D” 4S “2D” 4H
2. The way to handle a 5‑4 Major suit holding using both Stayman and Jacoby Transfers:
AXXXX AKXX XXX X INT ”2C” AKXX KQXXX XX XX INT “2C”
“2D” 3S “2D” 3H
