Pairs
Opps are silent
1N- 2♥
3♠ - 4N
5♦ - ?
3♠ just shows a max with 4 spades. 5♦ is 1430.

Sorry, not trying to be a jerk here, but if this were simply a matter of adding up key cards and if they total 4 to bid 6, I would not have posted the hand.
Agree with you about your comment regarding 4♦ but the call hasn't been specifically discussed, and you aren't sure if partner would take it as a suit or a cue.

On a serious field where 90% will be on some form of slam, 6NT I think will make more than 60%, and will make an overtrick sometimes.
6♠ will make an overtrick more often due to diamond discards, but they cancel with chances of a diamond ruff to put it down. So on average I think 6NT is worth it on a serious field.
Why 60%?, my calculations are that ♦J runs diamods 100%, ♦Axx runs diamonds 95%. ♦Ax runs them only 57% I think (and you have to add spade king onside to that), and ♦xx runs them only 50%.
You have to substract from that that they have a killing lead, and that they find it, but IMO this percentage is pretty low (below 10%)

I think 4♦ would be a Ctrl cue and deny a ♣-Ctrl .
The ♣ Ace as the missing key card could easily result in down 1 .
What would 3NT mean after 3♠ ?
If it means commence with cuebids, then a 4C cue by Opener would allow you to proceed with confidence.

- Two fast heart losers
- A heart lead when partner has Axx
- A club lead when partner has Qxx
- Needing to set up the diamonds opposite xx or Ax
- An elimination opposite ♦xxx
- An overtrick in 6♠ when we throw our club or heart losers away.

Am I missing something?
EDIT: To add to that, if partner has ♥Axx we have 50% top 50% bottom since we will be missing exactly ♠K and ♥KQJ Assuming all the field is in slam. ♥AJx might be worse though, still they need to lead the right one..

That was one of my reasons for 6♠ - sending partner 2 or more off in 6NT would not look good in the post-mortem. However, trying to construct a hand with such a holding consistent with the superaccept doesn't seem to be trivial. It may depend on style, e.g. would you bounce with ♠109xx, or on some other hand break to 3♦ with Jx (showing a weak doubleton)?

I doubt that Phil plays that a 3♦-break would show a weak doubleton. Or at least I hope he doesn't.
Would I bid 3♠ with 109xx Axx AJ AQJx? Yes.

Just seems absurd to do anything other than bid 6S.

... this also makes sense to me. I would think that at matchpoints a 60% shot at a top vs. a bottom is theoretically correct play? Take a classic book example: playing 3NT with an AKQxx suit in dummy, no side entry, opposite xxx in hand, with five tricks elsewhere. The books always say to scorn the safety play at matchpoints. OK, the current example is during the auction, but it feels very similar to me.

Andy captures the technical views of the 6♠ bidders, I think.
Quote
- A heart lead when partner has Axx
These just seem wildly remote. Mostly because there is hardly any room to be off the ♥AK, and there was no double of a the 2♥ transfer, and if the hearts are split, they probably aren't being led against 6N anyway.
Quote
More reasonable, but it still requires the right lead, and the ♣A in the wrong hand.
Quote
This appears to be the crux of the problem. However, if partner flashed ♦Ax, wouldn't you bid 6N?
Quote
Possible and I admit I hadn't thought of it.
Quote
This is simply the inverse of "not being able to run diamonds".
-----------------
I think that many 6♠ bidders are seeking low variance while sacrificing a little EV+ in the process.
I also think that there is an innate need to go plus on hands like this, because maybe the field will have trouble bidding this slam (I cannot fathom why), but we have all been in lousy pair games where 980 is 65%, even if 990 is 95%.
Last, there is a psychological bias that being +10 against the field is not as valuable as being +1100, even though the matchpoints might be the same.
I still believe a sim would be useful here. FWIW, partner held 8xxx AKQx Axx Ax.
