I'm not sure who it was (I'm guessing Justin) but we had a recent post advising against making bids that the bidder thinks 'must' mean a particular hand (always, in these forums, a hand that matches what we hold) because, no matter how compelling we think our reasoning is, there is simply too much risk that partner, who is not looking at our hand, will think it means something else. A very wise post.
So to those who think that 5♦ 'must' be a cuebid, take note: my guess is that the vast majority of partners would at least consider the possibility that 5♦ was natural. I think it was Rubens (of the Bridge World) who said that his advice was that if an undiscussed bid could be natural, it should be natural.
I am not denigrating the logic behind '5♦ is a cue'. I am denigrating the idea of inflicting this on partner. While I recognize that good partners should be afforded the opportunity to draw delicate inferences, I really, really doubt that this is the time to do so. We are morally certain that we have a small slam. We doubt that we have a grand, but would like to at least sniff at it. We absolutely DO NOT WANT to be declarer in 5♦: if there is one chance in 100 that we will get to play 5♦, that is too much.... after all, it is not as if the magic inferential auction will assure us of reaching a good grand, while it is a sure thing that 5♦ will be the wrong spot.
