unbalanced diamond methods

[gwnn]

I won't get into another lengthy philosophical debate thanks. :) In my original post I used 'min/max' loosely and similarly the word 'always'. Feel free to nitpick further (treating my posts as if they were legal documents) but I'm out.

 

Finally yes, it could make sense to have 2C instead after 1S as the 3-card raise, but that violates my "simple and not too far from optimal" rule. I don't want to lengthen this further, I think by now everyone knows what the upsides and downsides are. And if anyone wants to adopt these methods in their system, they are welcome to precisely define "min/max/bad min/bad max/etc."

I play the following:

 

Opening 1D is unbalanced with 4+ diamonds, no 5 card major unless 7-5. If only 4 diamonds it will be three-suited, or 4 diamonds and 5 clubs in the 11-15 range. We open 1D with five diamonds and 5422.

 

After 1D-1H:

 

1S = Natural F1.

1NT = F1. 6+D 11-14 or strong hand unsuitable for other calls. Includes three-card support with 15-17.

2C = Both minors, 11-15. Could be 4D and 5C.

2D = NF. 11-14 with 5+D and 3H.

2H = Usually 4 hearts and minimum, but may 1-3-4-5.

2S = 3H 18+.

2NT = 4H 16+.

3C = 14-16 5-5 minors.

3D = 15-17 single-suited.

3H = Good heart raise, about (13)14-15.

3S = Void splinter.

3NT = Solid diamonds and stuff on the side.

4C = Void splinter.

4D = 7D and 4 card support.

 

After 1D-1S it is similar, but the 1NT rebid covers another hand type.

 

1NT = F1. As over 1D-1H but also covers 5D and 4H 11-15.

2C = Includes 1-4-4-4.

2D = NF. 11-14 with 4+D and 3S.

2H = 3S 18+.

 

After 1D-1M; 1NT responder can bid 2C to force game vs the strong hand types (opener bids 2D if "weak"). Otherwise responder usually takes preference to 2D, but may rebid his major. After 1D-1S; 1NT responder's 2H is natural and forcing to game, because we play 1D-1M as Reverse Flannery.

Yeah, looks good.

In AWM's system that Csaba and I used to play, 1nt was also 6+ diamonds. But 2d was a good hearts raise.
