South is captain. Let's say North shows pattern and 5 QPs at 3N.

1) With rules of short to long (and stop with odd for singleton or doubleton), king parity last

4C-4D odd diamond
4H-4S odd club
4N-5D odd spade, even heart
5H-5S no SK
Cards placed.

2) With rules of short to long (and stop with odd for singleton or doubleton), king parity first

4C-4H even kings, odd diamond
4S-4N odd club
5C-5H odd spade, even heart
Unresolved. Could be KJ32 JT854 KJ Q8

3) With rules of long to short (and stop for singleton only), K parity last

4C-4D even heart
4H-5D
Cards placed.

4) With rules of long to short (and stop for singleton only), K parity first

4C-4H even kings, even heart
4S-5H
Unresolved. Could be KJ32 JT854 KJ Q8

4♦-4♥(ask 1&3, 1/4)

Now you'll want to be in 6 anyway.

If it continues then
4♠-5♦(ask 2&3, 2/5 & a club honor)
so either KQxx Qxxxx xx Qx or Qxxx xxxxx Kx Kx

Using my cocktail:

4C - 4D [relay; even K-parity)
4♥ - 4♠[relay; K ♦ perforce)
4N - 5♣ (relay; K ♣ perforce]
5♦ - 5♥ (relay; no Q♥, so Q♠)

[sieong]

EPCB.
4♣ - 4♦ (even ♥)
4♥ - 4♠ (all odds, or ♠ is of different parity)
4n - 5♣ (odd ♠ odd ♦ odd ♣)
5♦ - 5♠ (♠Q ♦K)

Honor structure resolved.

With some ambiguity left out:

(...)
3N-4♣ (10-12 hcp (say); relay)
4♦-4♥ (even # of kings; relay)
4N-5♣ (odd # of queens, no ♥K; relay)
5♦-5♥ (no ♠K (hence ♦K+♦K); relay)
5♠-6♥ (no ♥Q; contract)
