If you show keycards rather then ask for them you have more flexibility.
So 4♠ would be an even number of keycards and 5♦ an odd number with K♦, at the same time denying K♣

I don't understand this.

Instead of 4♠ being the key card ask, use 4♠ to show an even number of keycards and higher bids to show an odd number of keycards plus specific controls. This way the partnership will be in a better place to establish whether the grand is on if all keycards are there.

After a 5♦ bid:
Sign-off in 5♥
Bid 5♠ to show all keycards, but no Q♥
Bid another unshown control to show all keycards plus the Q♥ looking for the grand
Sign-off in 6♥

Here's the full hand, the ♠Kx and the auction we didn't have. No One bid slam, maybe next time.
Not a great slam, needing ♦ to break 3-3 , should I be worried about this one? Cancel that ! I can ruff a D and get back to hand with a S ruff

I open 1N (playing 12-14) with that hand, then superaccept (even though my partner hates superaccepts) the transfer if I get a chance. No slam try after that - looking at the West hand it would take a perfect 14 from partner for slam to even have a chance.

Incidentally, after a club lead, even assuming the spade is onside, you still need a 3-3 diamond break. Holding the North cards I am 100% leading a club on that auction.

3♥ is a competitive bid here given it will struggle to make opposite a minimum responder. On that basis I would not be bidding 4♣ as responder as the hand is a touch too weak for that

Of course you don't need a 3-3 diamond break, J is doubleton 1/3 of the time which brings it up over 50%.

The hand is way too good for 1N, even with a superaccept, partner won't bid game on plenty of hands that will make game. It doesn't say whether it's IMPs or MPs, but never at IMPs and rarely at MPs (people who play weak NT much more rarely open (24)(25) hands 1N than those who play strong).
