Canary Club

• 5C: 0 or 3 KC
• 5D: 1 or 4 KC
• 5H: 2 or 5 KC w/o the trump Q
• 5S: 2 (or 5) KC w/ the trump Q
• 5N: even number of KC and a useful void
• 5x: odd number of KC and useful void in x

Further asking bids from inquirer:

• After a response that does not tell about the trump Q (0/3 or 1/4 KCs):
  • 1st (non-trump) step: Q ask
  • 2nd (non-trump) step: specific K ask
• After a response telling about the trump Q (2/5 KCs):
  • 1st (non-trump) step: specific K ask

• lowest trump bid: no Q
• any other: have the Q. If possible we try to show lowest specific K (below 6trumps) as well.
  • E.g. with trump after 4NT-5-5:
    • 5N: has Q, no minor K, may or may not have K.
    • 6/: Has Q, lowest specific K
    • 6: no Q
  • With trump after 4NT-5-5:
    • 5: no Q
    • 5N: has Q, no outside K
    • 5, 6/: has Q, lowest specific K.
  • With trump after 4NT-5-5:
    • 5, 6: has Q, shows lowest K
    • 5N: has Q, no black Ks, may or may not have K.
    • 6: no Q

After a K showing response, if inquirer bids a new suit, it asks responder to bid the grand if he has that K, too. Over an ambigous 5N the next non-trump step asks to bid the grand if responder has a K.

• 7 trump shows 3 outside Ks
• lowest trump shows no outside Ks
• a suit shows either that K or the other 2.
  • for example given trumps, after 4N-5-5N:
    • 6: K, or both and Ks
    • 6: K, or both and Ks
    • 6: K, or both and Ks (inquirer must be careful!)
• 5N shows the lowest K one step over the trump suit
  • for example given trumps, after 4N-5H-5S:
    • 5N: K
    • 6: K or both and Ks
    • 6: both and Ks
    • 6: K or both and Ks

We play D0P1/R0P1:

• Double/Redouble: 0 or 3 KC
• Pass: 1 or 4 KC
• 1st step: 2 or 5 w/o the Q, etc.

Continuation is as before.
