When I wrote for Bridge World in 1991 about ‘Two New Bidding Ideas’, there were actually three, but the third was long and involved and thus they chopped it. The unusual idea was not responder’s transfers but opener’s transfer rebids after the 1NT transfer response.
Here
is a short summary.
After
1H or 1S opening:
1NT: Cs or balanced hand.
2C: Ds
2D: Hs
2H: Ss.
After
responses of 1NT (Cs or balanced hand), opener uses transfer rebids.
After
1H-1NT:
2C: Ds or balanced hand.
2D: Hs
2H: Cs.
After
1S-1NT:
2C: Ds or balanced hand.
2D: Hs
2H: Ss.
2S: Cs.
Over 1H:
1S: 4+S, standard
1NT: Cs or balanced or less than game force and less than 4Ss and less than 6Ds
2C: Ds, 6+ & less than GI or natural GF
2D: Hs support, less than constructive or limit+
2H: Hs, constructive
2S: GI, 6+S
2NT: Cs, either GI with 6+Cs or fit showing with H support
3C: Ds, either GI with 6+Ds or fit showing with H support
3D: Hs, preemptive or GF
3H: constructive raise with 4+Hs
After 1H-1NT (Cs, or balanced, or less than GF and less than 4Ss and less than 6Ds):
2C: less than 6Hs, less than 4Cs, not enough for jump shift
2D: transfer to Hs with 6+Hs
2H: 5Hs & 4+Cs, not enough to make a jump shift in clubs
2S & above: like over standard notrump response
After 1H-1NT-2C (less than 6Hs, less than 4Cs, not enough for jump shift):
Pass: 5/6+Cs, less than GI values, 5Cs only if singleton/void in Hs
2D: 5Ds, singleton/void in Hs, not enough to bid 2NT GI
2H: 2Hs, less than GI values
2S: artificial, GF with balanced/semi-balanced hand or asking
2NT: natural, GI
3C: natural GF (with GI values bid 1H-2NT)
3D,3H: natural with longer Cs, GF
3S,4D: singleton or void in suit bid, heart fit, clubs, slam interest
3NT: natural, GF but little slam interest
4C: club length/values, heart fit, slam interest
After 1H-1NT-2C-2S (artificial, GF):
2NT: no singleton
3C: 3Cs
3D: 5Ds
3H: 3-5-4-1
3S: 4-5-3-1
3NT: 3Cs, balanced, extra values
Cheapest bid over 2NT, 3C, and 3D asks opener to continue to describe hand.
After 1H-1NT-2D (transfer):
2H: would pass natural auction 1H-1NT-2H. Opener continues to describe hand with extras.
2S: artificial GF, asks opener to further describe hand
2NT: natural, GI
3C: natural, GF
3D: natural, GF with longer clubs
3H: natural, GI
3NT: to play, little interest in slam
3S,4D: singleton/void in suit, heart fit, slam interest
4C: club length/values, heart fit, slam interest
After 1H-1NT-2H(5Hs & 4+Cs):
Pass: less than GI with no club fit
2S: artificial, GI in clubs or a GF. Opener bids 3C if would not accept GI, all other sequences GF.
2NT: natural, GI
3C: club fit, less than GI values
3D,3H: natural, GF, with longer clubs
3S,4D: singleton/void in suit, club fit, slam interest
4C: strong club fit, slam interest
Over 1S:
1NT: Cs or balanced or less than game force and less than 6Hs and less than 6Ds
2C: Ds, 6+ & less than GI or natural GF
2D: Hs, 6+ & less than GI or natural GF
2H: Ss support, less than constructive or limit+
2S: Ss, constructive
2NT: Cs, either GI with 6+Cs or fit showing with S support
3C: Ds, either GI with 6+Ds or fit showing with S support
3D: Hs, either GI with H+Ds or fit showing with S support
3H: Ss, preemptive or GF
3S: constructive raise with 4+Ss
After 1S-1NT (Cs or balanced or less than GF and less than 6Hs and less than 6Ds):
2C: less than 6Ss, less than 4Hs, less than 5Cs not enough for jump shift
2D: transfer to Hs with 5+Ss, 4+Hs
2H: transfer to Ss with S+Hs
2S: 5Ss & 5+Cs, not enough to make a jump shift in clubs
2NT & above: like over standard notrump response
After 1S-1NT-2C (less than 6Ss, less than 4Hs, less than 5Cs not enough for jump shift):
Pass: 5/6+ Cs, less than GI values, 5C only if singleton/void in spades
2D: singleton/void in spades, no long suit
2H: artificial, asking bid, any GF or GI with 4/5Cs
2S: 2Ss, less than GI
2NT: natural, GI
3C: natural, GF
3D,3H,3S: natural, GF, with longer Cs
3NT: natural, GF but little slam interest
4C: club values/length, S fit, slam interest
4D,4H: singleton/void in suit, S fit, slam interest
After 1S-1NT-2C-2D (singleton/void in spades, no long suit):
Pass: 4+Ds or 5-1-3-4
2H: 2/3Hs and less than 4Ds
After 1S-1NT-2C-2H (artificial, asking bid, any GF or GI with 4/5Cs):
2S: not 4Cs and minimum
2NT: not 4Cs and extras
3C: 4Cs and minimum
3D & above: descriptive with 4Cs and extras
After 2S, 2NT, 3C the cheapest suit bid asks for further description.
After 1S-1NT-2D (transfer to Hs with 5+S, 4+Hs):
2H: would pass 1S-1NT-2H. Now 2S shows 6+s, only 4Hs, does not promise extras.
2S: would bid 1S-1NT-2H-2S
2NT: natural, GI
3C: asking bid, GF, opener describes shape of hand, 4C if 5-4-1-3, 4D if 5-4-0-4.
3H: natural, GI
3D, 3S: natural, GF with longer clubs
3NT: to play, natural, little slam interest
4C, 4D: singleton/void in suit, H fit, slam interest
4H: like 1S-1NT-2H-4H in standard.
After 1S-1NT-2H (transfer to Ss with 6+S):
2S: would pass natural auction 1S-1NT-2S. Opener continues to describe hand with extras.
2NT: natural, GI
3C: asking bid, GF. Opener describes hand, bidding above 3NT with 3+Cs.
3D, 3H: natural, GF with longer clubs
3S: natural, GI
3NT: to play, little interest in slam
4D,4H: singleton/void in suit, spade fit, slam interest
4C: club length/values, spade fit, slam interest
After 1S-1NT-2S (5S & 5Cs):
Pass: to play
2NT: asking bid, any GF or GI with 3+Cs
3C: to play, less than GI
3D, 3H: natural with longer Cs
3S: natural, GI
3NT,4S: to play, little interest in slam
4C: C fit, slam interest
4D,4H: singleton void in suit, C fit, slam interest
After 1M-2C (Ds GF or 6+Ds less than GI):
2D: no game interest opposite 6+Ds and less than GI
other: at least game interest, forcing
After 2D, pass with the weak hand, bid with GF.
After other than 2D, responder’s cheapest bid not including 3NT shows the GF hand, all other bids are natural and descriptive with the weak hand. For example 1H-2C(transfer)-3C(Hs & Cs, big hand)-3D shows Ds, GF, while 3H, 3S, 3NT etc. would be natural with weak hand & 6+Ds.
After 1M-2C (Ds GF or 6+Ds less than GI):
2D: no game interest opposite 6+Ds and less than GI
other: at least game interest, forcing, so 1M-2C-3D is forcing. To invite game bid below 3D first, and let responder show hand type.
After 2D, pass with the weak hand, bid with GF.
After other than 2D, responder’s cheapest bid not including 3D or 3NT shows the original GF hand with Ds, all other bids are natural and descriptive with the weak hand & 6+Ds. 3D shows a minimum weak hand and no other descriptive bid available below 3D. Example, after 1H-2C(transfer)-3C(Hs & Cs, big hand): 3D shows minimum 6+Ds, 3H is any original GF with Ds, and 3S, 3NT etc. would be natural with maximum weak hand & 6+Ds.
Note that 1M-2C-other by opener-reply by responder-3D is not forcing. This is how opener can invite.
After 1M-2D-2M, responder with weak hand & 6+Ds, can raise to 3M with 2 in M and minimum, or bid 4M with 2 in M and maximum.
After 1S-2D (Hs GF or 6+Hs less than GI):
Just like 1S-2C but with Hs instead of Ds. Same scheme applies.
After 1M-transfer to 2M-2M:
Pass: less than constructive raise
2NT: Jacoby 2NT like, GF, asks for further description
3C/3D: natural/semi natural with limit raise values
2S/3H: natural/semi-natural with limit raise values
3M: limit raise, spread out values
3NT: choice of games with flat hand, 3 in M
Above 3M: slam tries with 3 in M, singleton/void in suit bid
After 1M-transfer to 3M-3M:
Pass: preemptive raise
3NT: choice of games with flat hand, 4 in M
new suit: void in suit, slam try
4M: 5+ in M, better than a preemptive raise directly to game but no slam interest
After 1H-1NT-bid above 2H or 1S-1NT-bid above 2S, the cheapest bid is a GF asking bid. If the cheapest bid is in suit and is not opener’s major, then 3 of opener’s major replaces the suit bid. For example after 1H-1NT-3C, 3H shows Ds while 3D is artificial GF asking for further description.
