Rank intermediate ability member here, but I have played close to 1,500 tournament deals vs GiB,
and this is the first time I have ever heard of a cue bid at the 6 level after RKCB. Is this really
a convention which could add value to the product for any but a handful of the most expert members?

This auction is also helpful in drawing attention to GiB’s predilection for overruling even a strongly
bidding partner’s choice of contracts in most cases where GiB has a singleton trump, or has any singleton
if NT is bid. Anecdotally speaking I have the impression such action costs much more that it gains,
and I wish some rule could be written, or some simulation could be turned off, so as to allow me to make
a lot more final decisions when the bidding clearly indicates I have the master hand.

How is GIB overruling you - you're the one who set spades as trump...

Bid explanation box is cut off by the edge of the graphic, and I do not see where I agreed to ♠ as trump.

Do you agree with what I said about GiB's habit of overruling the better hand, even if this deal is not an example?

4N = "Blackwood [S], 4+H, 4+S..."

Fair reasoning --> how does one ask for aces without running the risk of (1) spades being the interpretation or (2) the auction stopping? 4SF?

I cannot remember if I checked the bid explanation for 4NT. Add that to my list.

I would have had no idea that (S) constituted agreement that Spades were trump. Add that to my list.

[mgoetze]

I don't know why people are always in such a hurry to ask for aces but 2♣ FSF is definitely the right bid here.

I agree that it's somewhat confusing but my interpretation is that the ONLY reason Blackwood (or RKCB) here implicitly agrees spades is because FSF is available as a forcing bid. If it weren't, in my mind, 4NT doesn't agree anything yet.

My interpretation is that asking for aces with no suit agreed is just bad bridge in 99.99% of all cases where people think of doing it, and there is really no reason for a bidding system to even offer this possibility.

GIB assumes that if you set a suit as trumps for the purpose of RKC, you're also showing support.

However, I thought the problem of pulling 6NT to 7 of the presumed trump suit was fixed sometime last year.

Thanks for the response.

Two things I did not consider before posting were:

(1) the 4NT explanation (I thought RKCB asked for key cards and that was it)

(2) that my best 2nd round bid was 2♣ (I was too fixated on the great ♥ suit)

I do think that my remarks about GiB usurping the final decision have merit, though,
and I hope some adjustment can eventually be made by way of a fix for that.

A new version of GIB was released on Oct 18, 2011... We call this GIB version 19...
GIB will now pass a 6NT decision after a suit RKC instead of insisting on bidding the suit in a grand slam

[georgi]

It was fixed to prevent GIB going up after 6NT in cases 6NT is assigned as contract after cuebidless questioning from 4NT.

Supposedly 4NT bidder would inquire Aces and Kings/(Queen of trump). Then it wasn't predicted a case that it will be issued new cuebid call instead of deciding contract somehow.

In general it wasn't predicted a case when you will be asking in suit X but it will be claim contract in suit Y. It would be hard to be distinguished in various of situations which is will and which might lead to "whoops" effect.

GIB would definitely pass on 6NT followed the 5♥ reply or 5NT-some answer-6NT.

It could be added such case of course, but here the desire was different i guess. Player just wished 6♥ to be final contract. Wasn't issued as real cuebid.

Likely the better sequence continuation instead of 4NT would be 2♣ as 4SF. Then could bid ♥'s again making them your only one promised suit(6+ for sure). If you lucky to get fit, then 4NT would let you play on NT or your suit whatever you like. If not seen 2+ cards in hearts, then what's wrong with 6NT if Responder is keen to reach slam. AKJxxxx is not so standalone suit resisting on singleton/void. Partner hasn't promised even a card in hearts so far neither NT shape.

You bid this hand terribly and deserved what you got IMO. Of course, the worst bid is the pass over 7S.

For the 6 level cuebid convention, it is only useful if gib can make such a cuebid. If human cuebids, gib would almost always sign off.
