16 -21 HCP, 4 Card Major with 5+ MInor

[Shugart23]

Yes, we use IMPrecision responses so 1C-1D is roughly 0-4 hcps or 11+ hcps with any shape. After this, we deviate from IMPrecision and 1C-1D, 1H is (usually) balanced but can be certain other shapes. So

 

1C-1D,

.....1H-1S (0-4 or 11+ bal)

........1N (11+ unbal with spades but not hearts)

........2C (11+ unbal with majors)

........2D (11+ unbal with both minors)

........etc (11+ other)

 

I wasn't recommending this (doesn't work for 1D 0-7) but I think what we do is a good example of how a system ought to "branch".

 

My other example (Meckwell) would be a better fit for you. They also branch.

 

 

 

1C-1D

.....1H-natural, possible canape

..........1S-0-7 with 4+S

..........1N-0-4 without 4H or 4S, forcing

..........2C-6-7 without 4S or 2H

...............2D-stuck

....................2H-2 hearts

..........2D-6-7 with 3+ hearts

...............2H-not interested

....................2S-and 4S

..........2H-0-4 with 4+ hearts

..........2S-6-7 with 5S and 3H

..........2N-? Don't know what they do but I like this as 6-7 and 4+H

..........3m-6-7 and 3H/6m

.....1S-natural, possible canape

..........1N-0-4, other, forcing

..........2C-6-7, not 3S

...............2D-stuck

....................2H-5+ hearts

....................2S-2 spades

..........2D-6-7, 3S

..........2H-6-7, 3S and 5H

..........2S-0-4, 4+S

..........2N-can't remember, like 4+S and 6-7

..........3m-6-7, 3S and 6+m

..........3H-6-7, 3S and 6+H

.....1N-17-19

.....2m-5m, no 4M

.....2H-forces 2S

..........2S-forced

...............2N-GF bal

...............etc-natural, forcing? can't remember

.....2S-almost GF with 3-suited (4441s and 5m4m31s)

..........2N-asking

..........3C-nf, preference

..........3D-nf, preference

.....2N-22-23 bal

.....3m-invitational?

.....3M-can't remember

 

If you like this, maybe someone can fill in the gaps.

 

thanks, I do like this as some of it might fit in nicely with what we do now

I've used the following structure, where 1H is strong and 1S may be canapé (even with longer hearts). I think the 1C-1D; 1S sequences turn out pretty good, so if you can make it work with opener still being unlimited, then I guess everything is fine :)

 

1C-1D;

1H = 20+

1S = 16-19, any unbalanced with 4+ spades (may be balanced with good 5 spades), except if at least 5-5 spades and another

..1NT = Relay

....2C = 5+ spades

......2D = Asking for side suit, forcing and 5--7

........2H = 4 hearts

........2S = 6 spades

........2N = 5332

........3m = 4 card minor

....2D = 5+ diamonds, 4 spades

....2H = 5+ hearts, 4 spades

....2S = 5+ clubs, 4 spades

..2X = 6-card suit, 5--7

--2S = 4 card support, 3--7

1N = 17-19

2C = 5+ clubs, denies 4 spades, 16-19

..2D = Invitational relay

....2H = 4 diamonds

....2S = 4 hearts

....2N = 6+ clubs, minimum

....3C = 6+ clubs, extras

..2M = Invitational with 5+ major

2D = 5+ diamonds, denies 4 spades, 16-19

..2H = Invitational relay

....2S = 4 clubs

....2N = 4 hearts

....3C = 6+ diamonds, minimum

....3D = 6+ diamonds, extras

..2S = Invitaitonal with 5+ spades

..2N = Invitational with 5+ hearts

2H = 5+ hearts, denies 4 spades, 16-19

2S = 5+ spades and 5+ minor, 16--19

2N = 5-5 majors, 16--19

thank you for taking the time to write this out
