As a matter of bridge theory, it is generally not a good idea to have the limited hand, here 2N, asking for aces
Instead of
2N-3
♠; 3N-4
♣; 4
♦ = RKC(
♣)
one could always play
2N-3
♠; 3N-4
♣; 4
♦ = controls in diamonds, hearts and spades (so "showing", not "asking")
2N-3
♠; 3N-4
♣; 4
♦-?:
4
♥ = Do you have at least 4 key cards, partner?
...4
♠ = Yes, but I don't have the trump Q.
...5
♣ = No.
...other = Yes. I also have the trump Q, but I don't have ___
4
♠ = Do you have at least 3 key cards, partner?
...4N = Yes, but I don't have the trump Q
...5
♣ = No
...other = Yes. I also have the trump Q, but I don't have ___
4N = Do you have either at least 2 key cards and the trump Q or at least 3 key cards, partner?
...5
♣ = No.
...other = Yes, but I don't have ___
5

briannz556 writes 'North opens 2N. My question is what is the best way to get to slam 6N / 6♣. We play transfers & control bidding. I've toyed with:
2N - 3♠ - 4♣ - 4♦ - 4♥
but then feel I should just bid 5♣ and let North make the decision. But it doesn't grab me as being ideal.'

Non-expert comments...
-- In my favorite version of Muppet, 3♠ is a ♣ transfer and then 4♦ is RKC for ♣s but, lacking that understanding, I like JohnU's Gerber 4♣.
-- There seem to be 12 top tricks, so you would like to reach at least 6N and 7N by North is reasonable.
