Blackwood convention and Queen of trump

Back to the summary
Responding to Blackwood 5 Rkc
  • 5 ♣ with 3 or 0 key(s) : that's30
  • 5 ♦ with 4 or 1 key(s) : that's 41
  • 5 ♥ 2 keys without Q trump
  • 5 ♠ 2 keys and Q trump
  • 5 SA 2 keys and a void

If you are looking for a big slam, or even to ask for a small slam if one key is missing, you may want to ask your partner if he holds Q trump. As you have noticed, you know about Q trump only in case your partner has 2 keys.

Exercise E6282 4 NT = direct Blackwood (no control sequence as S holds them all!). In this case, no problem N has Q trump...
 
Exercise E9381 The pair has all the keys. How can the responder know if the opener has Q trump?
 
 
How can you ask your partner about Queen trump ?
One will use the "collante" :
  • With a ♥ or ♠ trump : after a 5 ♣ response, using the "collante" is using the suit right above 5 ♦, asking : do you have Q trump ?
  • With a ♠ trump: After a 5 ♦ response, 5 ♥ is asking : do you have Queentrump ? It is still time to stop before small slam.
  • With a ♥ trump After a 5 ♦ response, the question is asked with 5 ♠ (you must skip 5 ♥ which would be a Stop). 5 ♠ : do you have Queen trump. Then you can't stop before small slam. Therefore, you may ask the question if and only if a big slam is possible, meaning holding all keys!
