I'm a simple soul, so for me with this hand and combined strength it is simply a question of aces.
1NT - 2NT (compulsory transfer to clubs)
3♣ (forced) - 4NT (spade void ace ask)
??reply?? - If 5♣ = 0 ace => pass, if 5♦ = 1 ace => 6♣, if 5♥ = 2 aces => 6♣.
Grand would need an ideal but for us undeterminable hand.
On the other hand, we do have a side KQ ask when we are playing in a major, so it is a simply a partnership decision to play it with a minor.
1NT - 2NT
3♣ - 3♦ (side KQ ask)
3♥ = K♦ or Q♦ (or both) - 3♠ = what about hearts?
3NT = K♥ or Q♥ (or both) [so opener has K♦+Q♥] - 4NT (spade void ace ask)
??reply?? - If 5♣ = 0 ace => pass, if 5♦ = 1 ace => 6♣, if 5♥ = 2 aces => 7♣.
This way grand is a laydown if partner has ALL the right cards (apart from a ruff of the opening lead).
If the Q♥ was missing but he had the others, I would think about still bidding 7 as there is a better than 50% chance of partner having another trick.
