[blml] "Demonstrably" - practical meaning?

[Guthrie]

ROSEMARY:

I'm trying to remember what we decided ....

After a 2-suiter auction ... e.g.
2D - 2H - ;
3C - 3D - ;
??
Up until recently the only rebids were
- 3H = S & H
- 3S = C & H
- 3N = D & H

There is a danger that partner may pass your transfer 3N reply, so we
added *forcing* rebids ....
- 4C = C & H asking for 6 keycards (CK & HK are keycards)
- 4D = D & H asking for 6 keycards (DK & HK are keycards)

[db] I thought that 3S was the only bid to show C & H, but what you put 
here  makes sense.

Similary after ...
2D - 2H - ;
3D - 3H - ;
??

But how do we respond to ...
2D - 3D - ;
3H - ??

[db] Is this a "typo"? Can 3H be anything else than the normal RKCB for Hs?

In Stratford, I was 4414 and bid 3N, hoping that you would take me as 
that shape. I couldn't be strong and flat; with that shape I would 
always bid 3H. At the time, I guessed that you must have an extreme 
one-suiter as with say 6331 shape, you could not risk the likely 
2-suiter opposite. The problem comes when there is an extreme  2-suiter 
opposite. I supppose opener just has to bid the lower one?

It was a "typo". I was talking about simple two-suiter auctions and the 
minor 2-suiter starts...

2D - 2H - ;
3H - ??

or
2N - 4H
??
