How should you bid this?

---

[Cyberyeti]

1♦-1♥
1♠/1N depending on style-2♣
2♥-

And now If parner bid 1N I would use exclusion, check for ♥Q and bid 6♥, yes 6N(N) is better but I don't know about ♠Q.

If partner bid 1♠ I bid 3♣ over 2♥, partner probably bids 3N with both suits well upholstered 4♣-4♦ and blackwood, queen ask -> 6♥

Our weak NT auction would be 1N-2♦-2♥-3♣-3♥-4N(exclusion, 4♠ would be kickback)-5♦(1)-5♠(♥Q?)-5N(no)-6♥

Interesting, should one go for it and bid 7NT in an expert MP field? What is the best strategy?


As Mike Lawrence pointed out in another thread 172 is not going to win it

Getting to any grand slam is likely a very good score, also in expert fields. That is, if you then proceed to make it, of course.

Probably easier to get to a grand with a weak 1N or short ♣ opener, otherwise
1♦-1♥
1♠-2♣ 4SF
2♥
to start as per cyberyeti, but then depends on whether 2♣ is GF or not. If GF 3♥ is a slam try and you have plenty of space to establish controls. Otherwise bids above 3♥ would do the same.
