Partner make 1 slam try and stop.

partner could bid 5♦, and since we hold ♥A we would know he has a diamond void. When the reason you bypass 4NT is that you have a void I rather show it than show other control, it is not perfect (nothing is) but IMO is best.

I tend to agree with this. IMO if you have a void and have a way to show it many times its the best bid you can do.

 

Anyway the problem & solution is essentially the same after 5D (showing a void) you either soff in 5H or make a pick a slam 5Nt. Just jumping to 6H is not goood enough.

My preference in these situation is to just treat any bid above RKC as exclusion (unless impossible on the auction). Nothing is perfect but if I'm not willing to RKC then it's frequently because I have a void anyway, so I'd rather just formalize the responses and eliminate the guessing.

 

"So what do you do with xx in a side suit?" If the auction is this high and no one has bid the suit, I key card and live with it. If you're missing, say, AK of clubs and A of hearts, and you choose to cue bid instead of RKC, how do you know that you won't reach slam opposite a club control and be off two aces? You can't protect against both and the defense might miss the AK of clubs, but never 2 aces. And bidding 7 (obviously not on this hand but another) will be damn near impossible without key card.

 

"What if RKC won't tell you what you need to know?" If I have lots of key cards and just need "stuff" 5 of the major should send that message.

I beg of you partner please stop with these 5 level cuebids or 4 level above kickback, over and over and over again....lets just play rkc, kickback.

 

You forgot Gerber ...

This "artifical method" is forced on you by the lack of bidding room. Other methods are not possible.

One alternative method that certainly is available and clears up many of these cases is to use denial cue bids. Instead of bidding a suit where you have control, you instead bid the suit where you lack a control (or need to know about a specific control and can place the contract or otherwise take control once you find that out). This elimates the requirement for LTTC and is imho much simpler to play for intermediates without detailed agreements.

 

Incidentally, it is indeed obvious that 5♦ shows a spade control but a matter of agreement as to whether it also shows a diamond control. Of course, the real solution to this would be finding out about the heart fit and extras at the 3 level. That ought to be easy if South opens a strong 1♣ or even a nebulous 1♣ with transfer responses.
