How do you bid this grand slam?

1♠ - 2♣
2♥ - 2♠
3♥ - 3♠
4♣ - 4♦
4N - 7♠
1. 1♠ = Forcing and unbalanced
2. 2♣ = GF Relay
3. 2♥ through 4♣ patterns out declarer to be 5=3=5=0
4. 4N is 10-11 zzz points.
North can place South with the three Aces, and at least one of the red queens, so it rates to be stone cold if its the ♦Q, or at worst a 50-50 shot to locate the ♦Q.
Winner - BBO Challenge bracket #6 - February, 2017.

East passes as Dealer.
Whatever you open as South, West passes.
How do you get to 7♠?
D.
1♠ 2NT1
4♣2 4♦3
4NT4 5♣5
5♦6 5♥7
7♠
1. Jacoby
2. Void
3. Cue 1st or 2nd
4. RKCB (excluding the ♣A given the void
5. 1 or 4
6. Asks ♠Q
7. ♠Q and ♥K
All is well if Jacoby 2NT denies a shortage and therefore 4♦ promises a high card. If not you may need another try after 5♥.

3c (void/singleton)-3nt (non serious slam try);
4d (good suit)-4h (cue);
5c (exclusion)-5d (1/4)
5h (queen)-6d (q+d king);
7s - pass

1S - 2N
3C - 3S
4C - 4D
4H - 5H
5N - 7S
Pass
Note that I am assuming that opener does not rebid 4D to show a 5-5. It is not that I do not like this approach, but rather that I believe that to make this bid both suits need to feature good quality suits. (The failure to bid 4C to show a void confirms I assumed the 5-5 jump bid approach.)
Thus 3C showed shortness, 3S showed no cue bid available and is waiting - one should not sign-off in 4S with such excellent trumps and welcome news about such useful shortness - and now opener's 4C confirms a club void. Now it is easy for responder to cue bid Kings having denied a red suit Ace with 3S. After responder's 5H bid, all that needs to be done is to check for trump suit quality with 5NT.
I like this sequence the most. Totally straightforward and logical. Once N denies Aces, he can start showing Kings. Simple.
Thanks.

5♣--5♦ Exclusion Keycard Blackwood (1430) --> 1 Key card
5♥--6♦ Spade queen? --> Yes and king of diamonds
6♥--7♠ Grand slam try: Do you have further values outside of clubs(e.g. king of hearts or a fifth trump etc.)? --> Yes, I do

3♦(LSGT initially)-4♠
5♣-5♦
5♥-6♥
7♠
Not ideal, partner's spades might be worse than this but not by much in that he doesn't appear to have ♣AK and 6♥ sounds more enthusiastic than other things he could have done.
**edit, actually it occurs to me that 3N showing 4333 and enough for game is a better bid than 4♠, now 5♣ is exclusion and the auction continues 5♥(1)-5N(Q♠?)-6♦(yes+K♦)-6♥(bid 7 with the K or Q)-7♠**
Another way we could have bid it:
1♠-2N
4♣(voidwood)-4♥(1/4)
4N(Q♠?)-5♦(yes +K♦)
5♥(I have one of ♥K/Q bid 7 with the other)-7♠
1♠-2NT, 4♣(=Exclusion at fourth level)-4♦(=1/4 keys), 4♥(=?Q)-5♦(=Q plus ♦K), 5♥(=?forQ/K)-5NT(=yes K)-7♠(Lovera)
