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

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

 

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)
