I cue: in my methods, 4N is the
♠ cue, which might not be the best usage on this auction.... now neither side can keycard.
I am not confident that partner HAS to have a
♦ control. In a jammed auction, the lower limit of all of his
♥ raises is reduced: thus he will bid 3
♥ on a hand that was, in an uncontested auction, a heavy 2
♥ bid, and he will bid 4
♥ on heavy 3
♥ hands... thus he needs 4
♦ for all heavy 4
♥ raises, with or without a
♦ control.
So I like my hand, but cannot drive to slam based on a keycard response (unless he shows all of them). If he bids 5
♣ over 4N, I bid 5
♥, confirming a
♦ problem.
I think that 5
♥ by me directly should also express
♦ concern, but my chosen sequence is an overall weaker one: 5
♥ insists upon slam opposite 2nd round control: my slow route suggests that my hand is not good enough... so partner needs a super hand to accept my slow route.
5
♥ would get us to slam opposite KQx KQxx x AQJxx.... 4N followed by 5
♥ won't... but it would opposite KQx AKxx x AQJxx. Maybe I am being too cute with my distinctions... if so I am sure someone will set me straight
