For instance if you had caught partner with Kxxx Kx Axx KQxx, all 7c needs is a 4-2 break in clubs.
You'd have to bid it quite well.
Yes, it does indeed need some good bidding to get there. But most of the methods are well-understood and extremely well-illustrated by Kantar in his book "Roman Keycard Blackwood", Slam Bidding for the 21st century, 4th Edition. You don't need any of the esoteric stuff either, simple stuff like two-suit RKC, Specific King Ask (SKA) which most people play anyway and SSA (Specific Suit Asking). There's one additional treatment that helps on this hand, it's similar to the auction 1m-1M-2nt-3d (checkback). Now opener can bid 4m or 4om to tell his pd that he has 3M, 4OM and a good hand. When it goes 1n-xfer-to-M-2M-3x, pd now bids 3M whenever he has 3-card support for Major, 3nt with no interest in partner's suits, 3y to experss interest in pd's second suit alone and 4x on a hand where he has both 3-card Major and 4+ minor.
With Kxxx Kx Axx KQxx it'd go
1nt-2d
2h-3c
3d-3s
4c-4d(RKC)
4s(1430, 3 keys), 4nt(Q-ask)
5d(low Q, 5c would show 0, 5d low Q, 5h high Q and 5s 2 Q; since Q-ask has so many steps now it can not be extended to show Kings when holding a Q)
Now responder bids 5s (Specific Suit Ask in spades)
Cheapest return to one of the two-suits denies third round control and isn't counted as a step. That apart the steps are:
1st step: xx or Q
2nd step: Kxx(x)
3rd step: Kx
Raising SSA shows KQx. With a singleton and "lots of trumps" (this needs a lot more discussion), jump to 6 of cheapest suit.
On this hand pd bids 6d. 5nt is 1st step, 6c doesn't count, so 6d is 2nd step showing Kxx(x).
So there you have it: pd has Kxx or Kxxx of spades, Kx of hearts, AofD and at least 4 clubs to KQ. 7c is clear.
In the auction I posted first, 3c was a temporizing bid to find out if pd had 3 hearts. But I think recognizing clubs as a possible key suit, in that you can extract key card info about both K and Q leads to a really good slam. If you had chosen Diamonds instead, things don't work out as easily.
