ACOL 5NT opening bid Ever heard of it?

For example, opener has ♦AKQT65 ♣ AQJT532,
Opener open 5NT. If responder has no king of clubs, he response 6♣, in which opener passes. If he has the king, and no diamond ace or king, he bid 6♦ in which opener bids 7♣ knowing the responder has the club keycard. Responder may convert to 7♦.
Another example, opener has ♦AQJT532 ♣ AKQT65,
Opener open 5NT. Responder, having no club A or K, bid 6♣. Rebid of 6♦ ask for ace or king of diamonds and be replied 7♣/7♦ if responder has one.
I am wondering whether it works for all suits as well.

You cannot play this with a loser in both suits, nor with 6-5 as mentioned above. 6-6 is OK if the stiff is an ace. You do not want to open with a slam force with more than one loser, do you?

There is an advantage to play only in minors so that responder have 6♣, 6♦, 7♣ and 7♦ as available choices to play. The draw back is frequency.
There is an advantage to play 6 of a bid suit indicates no key card in the suit, allowing opener to explore. The drawback is that the partnership may play in 6 of a suit responder dosen't have a fit. (Say 6-1)

This is not a big problem because the suit will be solid (or solid minus A or K.

Yeah, I was being dumb and mixing it up with the 5M thought. Personally, if I considered these hands worth assigning an opening to, I think I would consider going over to a MisIry-style method or even just assigning 3 or 4NT after a strong 2m opening to be such a two-suiter. It strikes me more as a solution waiting for a problem than the other way about.

Of course on the 7 level this problem dose not exist.
On the other hand, there are several ways to show any of such kind of two suiter X, Y. X has a higher rank than Y
1X - any - 6Y
1X - any - 3Y - any - 6Y
1X - any - 3Y - any - 4Y* - any - 6Y * Y must be a minor
2♣ - 2♦ - 3X - any - 6Y
2♣ - 2♦ - 3X - any - 4Y* - any - 6Y * Y must be a minor
In addition to play strong two , ACOL:
2X - any - 6Y
2X - any - 3Y - any - 6Y
2X - any - 3Y - any - 4Y* - any 6Y * Y must be a minor
which make me wonder why we need a system so specified to one and only one missing keycard.

Playing Acol Twos to cater to a very rare hand type is not winning bridge. And as for missing only one keycard, well, you could assign some other meaning to a 5NT opening, but what would it mean?

It would be a specified or semi-specified two suiter capable at least 50% chance of small slam.
On the other hand, all example below may show two suiter ranging from 50% small slam to a likely grand slam. Responder should bid the grand if he thinks he has all the right cards.
For example,
1X - any - 6Y (50% small slam, e.g. missing one ace and one king of different suit)
1X - any - 3Y - any - 6Y (75% small slam, 25% grand slam on its own, e.g. both suit missing kings)
1X - any - 3Y - any - 4Y* - any - 6Y * Y must be a minor (75% small slam, 25% grand slam on its own, both suits missing some quarks)
2♣ - 2♦ - 3X - any - 6Y (small slam is certain, 50% grand slam on its own, e.g. missing one keycard)
2♣ - 2♦ - 3X - any - 4Y* - any - 6Y * Y must be a minor (small slam is certain, >50% grand slam on its own, one suit missing some quarks)
In addition to play strong two , ACOL:
2X - any - 6Y
2X - any - 3Y - any - 6Y
2X - any - 3Y - any - 4Y* - any - 6Y * Y must be a minor (may provide specified details)
Note that opener skipping Blackwood, Exclusion Blackwood and Control cue bids that would mean the hole should be the long suits themselves. Through the some gambling may be involved by the opener style.

Were you too polite to point out that partner's final pass was silly too?

I bid 4D, my partner bid 5C, I bid 5D hoping that partner would get the message to bid a major. Partner bid 5NT. (His diamonds were xxxx.) One more time, and I got to play 6D. "I thought they psyched" was his excuse.
