CAB rebid question

[chasetb]

Here's the bidding sequence (opps passing):

1♣ - 1♥

1♠ - 2♦

2♥ - 2NT

3♣ - 3♠

4♣ - ?

 

Partner was asking whether my 2nd round control was x or Kx(x), and my holding was EXACTLY ♣K . 4♦ would have shown x, 4♥ would have shown Kx(x), and 4♠ had no meaning (as I am relatively new to Precision, I figured partner would think I had forgotten what 4♣ was). Now, we have decided that the 3rd step to a CAB rebid would show exactly K singleton in this situation, but at the time I just winged it and showed the King. So if it happens again with a different partner, should I show the King, or show the shortage?

 

Oh yeah, 7♥ was bid and was cold, as partner held ♣AQ103 and RHO held Jxx!

I don't know what is "standard". But I think most of the time you should show the K here as it is more likely to both fill in your partner's honor sequences (as it did here) and/or help partner not place too many of your points in other suits (He has the x of clubs so he must have the K of ♦ to give him enough for his positive).

I haven't played CABs for quite awhile, but as I remember them a two-tiered structure works well...

 

 

Responses to the initial ask: none/third/second/first/first & second

 

Responses to the reask: length/strength/both

 

 

So in this example, S3/reask shows the singleton king.

I play a symmetric type of CAB responses:

 

Step 1: none

Step 2: King

Step 3: Ace

Step 4: Void

Step 5: Singleton

Step 6: AK/AQ

I use a two-tiered system as well. The initial ask was 3♣, and all possible responses are below:

3♦ = No control at all

3♥ = Third Round Control (Qxx or xx)

3♠ = Second Round Control (Kx or x)

3NT = First Round Control (A or voild)

4♣ = First and Second Round Control (AK or AQ)

 

Bidding 4♣ asks what my Second Round Control was. However it only has TWO steps (at least how I first learned it):

4♦ = Shortness

4♥ = King

 

After the hand, I realized that there should be a 3rd step, which shows both. If you don't have that third step though, do you show the length, or show the strength? I showed the strength, and in this case it payed off. I just want other people's opinions on what to do if the situation happens again.
