Full Disclosure and "Passes"

[hrothgar]

I've been spending a fair amount of time with the Full Disclosure application. I'm running into a number of instances in which I'd like to define specific meanings for passes.

 

At the moment, I have the ability to do so if there is a competitive auction. This makes perfect sense - so called "forcing passes" are probably the most obvious example in which players need to define a specific meaning for a pass.

 

Unfortunately, I'm running into a fair number of situations in which I need to define pass in "constructive" auctions and the software doesn't seem to support this right now.

 

Case in point, consider the following example:

 

The Scanian NT structure uses the auction 1N - (P) - 2N to ask for a weak doubleton

The bid is used with a number of different hand types. For the purposes of this discussion, the most significant are game invitational hands with a long minor.

 

Auctions like

 

1N - (P) - 2N - (P)

3♦ - (P) - P*

 

assign a very specific meaning to the final pass...

 

Ideally, I'd like to be able to alert these sequences.

Is that required? I suppose the final pass means that 3♦ rates to be a good spot or at least that the system does not offer any means of improving the contract, but that applies to all final passes. For example,

1NT-(pass)-pass*

Because we play Stayman, the final pass might be based on a weak hand with five clubs. We don't alert that (or specify it in Full Disclosure).

 

Ideally, Full Disclosure should be able to generate negative inference automatically, but negative inference applies to all calls, not only pass.

A Keri example:

 

1NT-(p)-2C!-(p)

2D!-(p)-P

 

1NT - whatever your range is

2C - puppet to 2D, many hands, from bail to GF+

2D - Forced

P - weak with diamonds - not three-suited.

 

Okay, it's pretty obvious, but I'd still want to tell the opponents; especially as in Standard Stayman it would have a very different meaning, and they're already confused by the word "puppet"...

 

I don't know if "competitive" allows the following pass to be described (I haven't tried it):

 

1NT-X-2C!-P

P - forced, says nothing about clubs; we'll play the potential 2-1 fit as long as it's undoubled (if doubled, we may still play it; but it will be 4-3 at least).

 

But I'm sure there are other situations like this if it is not supported.

You are obligated to give any information you have about the bid, and alert any non standard information about the bid, including possitive and negative inferences. so if you play normal transfer and pass 1nt you dont need to alert it is standard but playing keri when you and explain that partner prefer tont to 2d. I agree that sometime this isnt practicle and would understand if you wont alert it, but you should understand its off law. A side from this, the file will be much easier to learn a system of, if you explain that pass show invite with diamonds in Richard's example.
