For my part (I was S), after hearing 4♠ I decided that RKCB wouldn't tell me what I wanted to know (strong trumps).
I sort of agree. But what about before you heard 4
♠? Isn't it quite likely since you hold AQ
♥ that partner's reply over 4
♦ will be 4
♠? It depends a little on your cue bidding style but how are you really going to ask what you need over 4
♥ or 4
♠ by partner once you bid 4
♦. I think if you bid 4
♦ (and don't have some non-serious 3nt type agreement) you aren't going to get what you need from partner. What you need to know most about from partner, once he bids 3
♠, are the
♣A and the
♠KQ. Sure the
♥K and/or
♦Q would be useful cards, but you can finesse them at worst, and really it is the black cards you are desperate to find. If you aren't going to accept a sign off from partner (and are going to the 5 level anyways) why not keycard over 3
♠? Here you'd hear you were missing 2 keycards and end up in 5
♠. If you were missing but one you could ask for the Q. The bottom line is you will know where you want to be over every keycard answer, so why not key card?
P 1♦
