The explanation for South's 6♣ bid is "No king (below C)"
I had this hand (playing Just Declare) which the Robots had bid to 7♣. The 4NT by North was a RKCB ask with Clubs as trumps, followed by 5NT which is explained as "Query Kings". What responses are used after 5NT, and what does the bid explanation "No King (below C)" mean? Did South somehow show that K♠, or did South deny the K♠?
Thanks for any clarification.
