Bidding Slams The Blackwood Convention

Brilliantly explained ,thank you !

On your first hand 4NT is precipitate as you have 2 suits without the Ace or King . A 4C cue-bid is a standout . If partner can make a return cue-bid of 4D - still safely below Game - you can now perhaps use Blackwood or even make a second cue-bid of 5C and partner knows you need controls from him in both pointed suits ....
