Opinion: Blackwood or not?

[cf_John0]

Nobody has yet explained why we might need to Keycard for ♠ straight away, instead of agreeing the suit first.

Let me try.

(1)The responser want to reverse to 2S if the opener dont bid 1S; and

(2)there is neither void nor single in hand;

(3)Just concern the quality of trumps and side ctrls for a slam;

At these kind of cases ,why dont u bid RKC 4NT?

This explains why you might want to bid RKB for ♠ (although the hand is exceptionally rare - much rarer than a quantitative bid IMO), but it doesn't explain why you need to do it straight away instead of agreeing ♠ first via FSF.

I play this as quantitative with one of my partners. Not that it makes that much sense since you would probably first look for a fit. It happened once and I didn't know what to do with my minimal HCPs and solid 6-card diamonds. Just gambled 6NT in order to right-side the contract which turned out to be the right decision, but I'm not sure if it was the right bid.

IMO the responser considers she/he could be the master of the bidding period.

First, welcome to the Bridge Base Forum. I have noticed your a very recent poster. Second, what does this statement mean? IF 4NT is quantatitive, partner has just turned the auction over to you to be master. If it is some kind of blackwood, then partner has taken control. So are you suggesting it is blackwood? And if so, what kind (for hearts, for spades, for hearts and spades, for just aces)?

Meta-rules in most of my partnerships:

 

1: 4NT is quantitative where 4C is Gerber: Directly over NT openings, responses and rebids, and directly after Stayman and Jacoby Transfer and response.

 

2: 4NT is 4-ace on the first round only. Otherwise, keycard for: agreed suit/2C-er's suit/last bid suit in that order (when 2C isn't my strong artificial bid, there are other toys...)

 

3: Confusing bids are forcing (though I do like the variant I saw elsewhere: confusing bids below game are forcing, above game are to play).

 

So, for me it's RKC for spades.

 

I agree that this is probably not the best agreements, but I sleep nights before big (for me) games rather than worrying whether I remember "exception 1004".
