Unbalanced nebulous diamond

You may very well be right gwnn. We will have some space to look for games still, but perhaps it is better to show the minor right away. Here's what I've thought of:

 

1D--1H; 1NT (4 hearts)---

2C = GF relay, says nothing about hearts

2D = At least a mild INV in hearts. May be slam interest.

2H = To play, but opener may bid again with a monster

2S+ = Romex style game tries, prefer to show instead of ask. May be slam interest.

 

1D--1H; 1NT--2D;

2H = Minimum (11-13), now 2NT asks minor

2S = 4 spades, three-suiter, max (14-16)

2NT = Both minors, three-suiter, max

3CD = 5+ suit, max

 

After responder knows opener's minor, 3H is still a suggestion to play (was hoping for the other minor). With this method I like that opener can show a minimum without passing 2M, but it may be better to show the minor right away (double fits etc where responder can not afford a game try if opener is minimum).

 

1D--1S; 2D (4 spades)---

2H = At least a mild INV in spades.

2S = To play

2N+ = Romex style game tries

 

So here we can play the same principle. This principle is used in other sequences as well.

 

1D--1H; 1S (4 spades)---

1N = GF relay

2C = Pass/correct

2D = Usually spade support and at least mild INV, but might be GF with a nice heart suit

...2H = Min with clubs

...2S = Min with diamonds

...2N = Max, three-suiter with short hearts

...3CD = Max

2H = Natural INV

2S = Normal raise

 

1D--1S; 1N (4 hearts)---

2C = Pass/correct

2D = Relay, at least mild INV and often heart support

...2H = Minimum

...2S = Max, Hx in spades

...2N = Max, three-suiter short hearts

...3CD = Max, 5+ suit

2H = To play

2S = Natural INV
