an IMprecision 1N sequence

[straube]

Curious if Adam or Sieong have explored other continuations after such a start as 1N-2D, 2H-3D. In this sequence, responder shows either 5H/5D or 4H/6D and opener may have 2, 3, or 4+ hearts. The continuation goes something like...

 

3H-3 hearts

.....3S-5H, agrees hearts

.....3N-4H/6D, nf

.....etc-4H/6D

3S-4 hearts, agrees hearts

.....3N-nonserious?

3N-no interest, both side suits double-stopped or length

 

I'm wondering if fit could be agreed at the 4-level somehow. 3H seems like it should start some relay to differentiate 5/5 from 4/6 and shortness as well

 

3H-relay ask promising diamonds?

3S-3 hearts but no diamond fit

3N-no fit at all

4L-4 hearts

 

Anyway, I'm trying to borrow this NT structure for other situations (I want 1C-1S, 2C-3D to be 4S/6D or 5S/5D) and it would be nice to use the same continuation.

 

Any ideas?

3H-diamond fit

.....3S-5/5

..........3N-4/6, COG

3S-3H, no diamond fit

.....3N-4/6, COG

3N-no fit

 

One of our regular posters PM'd me about a step (at the 4-level) to show a double fit.

Thinking about continuations. For the first time the 4L bids are used by either partner.....

 

4m-set the minor

.....4m+1 is RKC

4om-agrees the major

.....4M-to play

.....4M+1 is RKC

4M-to play

4OM-RKC for the minor

4N-RKC for the M

 

which means that you can't immediately RKC for hearts unless you use 4N. I don't like to remember stuff like that.

 

Looking at a case for hearts and clubs it would go

 

3H-support for clubs

.....3S-5H/5C

..........3N-offer

...............4C-sets clubs

....................4D-RKC

...............4D-sets hearts, 6H/5C

....................4H-nf

....................4S-RKC

...............4H-6H/5C, nf

....................4S-RKC

...............4S-RKC clubs

...............4N-RKC hearts

 

3S-3 hearts, no club fit

.....3N-4/6, COG

..........4C-sets clubs

..........4S-RKC clubs (yuck but should be very rare)

.....4C-sets clubs (4/6)

..........4D-RKC

.....4D-sets hearts (5/5)

..........4H-nf

...............4S-RKC

.....4H-nf

..........4S-RKC

.....4S-RKC clubs

.....4N-RKC hearts

 

3N-no fit

.....4C-sets clubs (4/6)

.....4D-sets hearts (6/5)

.....4H-nf (6/5)

.....4S-RKC clubs

 

4C-sets clubs

.....4D-RKC clubs

 

4D-sets hearts (4+ fit here)

.....4H-nf

..........4S-RKC

.....4S-RKC

 

4H-nf (4+ fit here)

 

4S-RKC clubs (rare)

 

 

 

 

 

 

 

 

3H-3+m

.....3S-5/5

..........3N-nf

...............4m-sets m

...............4om-extras (6M/5m)

...............4M-6M/5m

...............4OM-RKC m
