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.
INT “2D”
2H 3D
3NT Pass
. (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.
INT “2H”
2S 4H
Pass or 4S

(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.
2S 2NT
3S,4S,3NT,Pass
(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”
2H 3NT
???
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
P/4H
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
