Vikings without tools

Hi all

Last night René had obligations elsewhere. Lucky me, Elske agreed to sit opposite me. She bid like a true Viking, dangerously high. I like that, though it costed me some time and palpitations to adapt. But no relays, we agreed to something Dutch Acolish. And then this game came across:

North Dealer
NS Vul
North
Q94
A9653
K74
K4
 
 
South
AKJ75
8
QJT6
A76

We had an undisturbed auction (involving Check back Stayman) to 4. But both hands fit like gloves, no wasted honours, so 6 is a very good slam. But it’s quite unbiddable in a natural system.

What about Viking Precision? Would it have gotten us to slam?

South initiates a gameforcing sequence with 1NT, North obliges with:
1. minimum, balanced or sidesuit in other Major
2. balanced
3. 3-5-3-2 distribution
4. 1 Ace
5. 2 Kings of the same rank
6. 1 Queen
7. Queen

Maybe the last couple of relays are not obvious, cause slam without trump Queen is a no go, and finding out is not without danger. But during the sequence South must feel like: “Really? Really? Really? Can it be?” And then slam is unavoidable.
