Responding to RCKB With Two Aces and Extra Length


Extra length = trump queen?  

20 members have voted

  1. 1. What constitutes extra length if partner's holding is unknown?

    • One more than promised?
    • Two more than promised?
    • Other?

It's not "extra length" per say. It's often done when the responder knows of a 10 card fit which the asker might not know about. When this happens, the responder pretends he has the queen and shows it even if it isn't present.

 

This hand was easy but what if responder has only six clubs?

The auction tells us partner does not have only 3-cards in clubs. Six of them is fine. You might discuss using something other than 4N for RKCB when a minor is trumps, however.

I think that is quite a statement. If I would have this auction, you can be sure that opener has precisely 1 or 2 clubs (and 4NT would not be asking for keycards for clubs).

 

Did you perhaps miss that the 1 opening was Precision?

No, I didn't miss that. I also didn't miss that the poster was responding to RkCB for clubs, or else he wouldn't have posted at all in this thread. I answered his question as given, not about the auction you or I would have ---and the part you didn't quote, recommending against using 4N as RKC for clubs, even made that clearer.

From what do you conclude that -in the system of the OP- opener cannot have:

AKQx

Good idea but irrelevant. In theory, we could play that 4C is

Minorwood but we have a different agreement (see below). Minorwood is

fine for natural systems but doesn't make much sense opposite a strong

club. Here's what opener's rebids would have been:

 

2, 2 - Alpha asking for fit and controls

2NT - Balanced 19-21

3 - Gamma asking for suit quality

3 - Cancels asking sequence and starts cue bidding

3, 3 - Zeta asking for precise holding

3NT - Signoff

4 - Beta asking for total controls

4 - Splinter asking for cue bidding

4, 4 - Signoff

4NT - RKCB

5 any - Signoff

Partner's actual hand was:

[hv=pc=n&n=sakqt3haq9d4ckq76&d=w&v=0&b=8&a=p1c(Precision%2016+%20HCP)p2c(8+%20HCP%2C%205+%20Clubs%2C%20GF)2d4n5d]133|200[/hv]

Knowing that responder had extra length helped him place the contract.

He can count three spades, one heart, one diamond, and six clubs = 11

tricks off the top. If seven clubs, then 12 off the top. In either

case, if spades run, 7NT is cold. If not, there's the heart finesse

and there may be a squeeze. And responder could have the jack of spades

and/or one or two red kings. Opener would have bid 5NT to check.

 

We didn't actually play this hand. The opponents did. They got all the way to 5.

Playing Precision guarantees that the opponents get these hands.

It seems to me that the 4NT rebid as RCB is completely redundant. Since a 3 rebid starts cue bids it is possible to envisage

 

1 = 16+

... - 2 = nat GF

3 = agrees clubs

... - 3NT = diamond control, no major control

4 = RKCB, etc

 

or, probably better, just making the Gamma ask before checking controls. It is certainly not true that Minorwood makes no sense in a strong club context. However, jumps to 4NT which skip 3 levels of bidding generally do not make sense. There is almost always a better option - here we have (arguably) at least 3 better options. In this case you are justifying the 7NT bid by saying that partner might have this or that but you could possibly have found out some of these things by taking a different route and thus bidding, or staying out of, 7NT with much more confidence. Of course you sometimes have to guess - the main attraction of a 4NT bid here seems to be knowing the opps will raise to 5 behind it. Otherwise it seems to be a poor choice.

If there is no interference, 3 Gamma will tell you that partner has six to one honor (the ace). Unfortunately, it doesn't include a way to show seven or more. Then 4 Beta will tell you that partner has four controls and that your total is ten but you don't know whether he has the ace of diamonds or two red kings. Then 5 or 5 Epsilon will tell you which.

 

But if there is interference, you may not get the chance to make three asking bids, even playing D1P2 and R1P2. That's why I can't find fault with 4NT. Partner will show the trump queen with extra length and thus 4NT potentially gets you more information than three asking bids.

 

In all my years of playing Precision, I can't remember another instance of Blackwood occurring in a 1 auction.

Don't forget we both speak English, while American is a different language. Languages evolve, and it is the duty of the young to attempt to change things, however misguided or unguided they may be.

 

I did spend my first 30 years in America, so I think I can justly claim to be fluent in the language :) .

Why 4NT vs 3? Sure, if it's repeated asking bids, maybe. But if not (and I don't think we play asking bids after our equivalent 1-p-1-2), 3 then 4NT makes everything clear. If they bid 5 first then I didn't get across that I only care about controls, though, I guess.

 

But I think that if I have shown 5, and have 7, and partner is keycarding rather than showing his suit, that I have "extra length". If partner doesn't have 3, and cares about the Q itself, that's a problem - but it's not my problem.
