How would this open and proceed with the benefit (or not) of your usual agreements?

[Cyberyeti]

1N-2♣
2♦-3♥(minor suit stayman, at least slam inv)
3N (no 5m, max)-4♦
5♣(cue, no spade cue, decent diamonds)-6♦

If we use our system from weak NT by moving ♥Q across for a small one:

1♦-2♦(inv+ not denying 4M)
2N (GF bal or ♣ or ♦ only)-3♣(asking)
3N (bal 15-16 ish)-4♥ (kickback)
5♦(2+Q)-6♦

West opens one diamond, shows a balanced minimum, east drives to D Slam.

1D..1S
1NT..2D .XYZ gf
2Nt..3D.
Etc.

I'll be the elephant and accept responder's quantitative no trump bid to 6NT, wishing instantly I had gone slower and hoping for a lucky squeeze..

Very reasonable at MP in a tough field.

Just the usual concern, source of tricks with. 2 balanced hands?

And another opening playing an unbalanced ♦ so opening 1♣. 7.5 mod. losers vs. 5 suggests a slam once a fit can be found.
1♣ - 1♠ GI
1N BD - 2♣ 5-card minor?
2♥ 2344 (min. or 18-19) - 4♦ SI
4♥ even KCs K♥ - 6♦
The 5-card minor ask follows the same structure as my 5-card Major ask over 1N to simplify memory recall.

That's interesting, because I refused: as I saw it, a good 13 with useful intermediates and Jx working, but not enough to get the green light.
This partner doesn't play XYZ but is usually accurate in his natural bidding.

We'll get to the play later
