May have posted about this before, can't remember. Here's Mark Abrahams detail of a king parity question/answer that comes after QP number but before DCB. Basically, the slave hand tells whether he has odd or even number of kings before scanning each suit.

http://www.users.on....ml#RSKingParity

The Parity Cue Bidding structure that awm plays uses a king parity question/answer after each suit has been scanned for odd/even parity. So I think he skips if a king is held in the first odd suit.

Both of these are (I think) just extra clues in figuring out which combinations of honors partner actually has.

We've sometimes run out of room when starting PCB too high. Say QPs are shown at 4D or perhaps worse. I've also frequently just wanted to know if partner has an ace or not. Wondering if it would make sense to do an ace parity question first (odd or even) and then scan suits for odd/even parity.

So there's a difference between an ace and a king. Maybe this wouldn't be a big enough clue later on? But sometimes knowing we're off two aces early will help. Or knowing we're missing one...

We used QP as the first step after shape is known, but on hands where you want to RKCB we used the next 4 steps after that ordering the suits by length.

So if shape is resolved at 3, 3=QP, 3=RKCB in longest suit 4 = RKCB second longest 4 3rd and 4 4th.

Sorry if you already knew all this and were specifically asking about the parity stuff.

np. We use continuations like yours, but especially at higher levels (where you don't have the terminator puppet) and space is tight and you (or we) don't have RKC available it's nice to find methods that give you the most useful information early.
