Advanced Bidding or Gambling

Frist hand

 

Second hand

 

My question is how would the partners bid these hands to arrive at 7NT

 

other than just gambling that they have the right cards?

The grand slam would appear to require either being able to place the Queen Jack of hearts in hand A OR knowing that hand B has a 4 card heart suit.

 

I think that it would be difficult to reliably reach 7 for many, perhaps most partnerships.

 

Good hand for relays

You give no indication of who dealt

 

The key is to impart the info that N actually has a 5 card club suit, so S can agree clubs, then allow N to blackwood and find out S has 3+Q♣+K♥.

 

Playing weak NT starting from N for example:

 

1♣(4+)-1♥

1N(15-17)-2♣(art ask)

3♣(top end 5♣)-3♦(stop initially, cue when he goes past 3N)

3♥(3 card support)-3♠(looking for stop, cue when he goes past 3N)

3N-4♣

4♦(keycard)-4♥(0/3)

4♠(Q♣?)-5♥(yes and K♥)

7N(can count 13)

Thank you cyberyeti and your sequence is impressive.

For me, 7N is hard but 6N is relatively easy using simple Acol[/hv]

We play the 2N rebid as GF not necessarily balanced, so starting from S, we get

 

1♥-2♣

2N(GF, not always bal)-3♣(says no more than that I have 5♣

3♦-3♥

3♠-3N

4♣

 

and as in my first post is possible, but less clear as N would bid the same way to this point with the A or K♣ switched to a small one.

 

You might have a chance if you open 1♣ with the S hand and get an inverted raise.

[apollo1201]

Yep, agree with inverted raises:

 

1C - 2C (11+, 5+ clubs)

3NT (18-19 bal with stoppers and only 3 clubs) - 4C (start cueing pls)

4D (cue) - 4NT (he stops H and I have QJ so we don't have 2 H losers)

5C (3 kc) - 5D (queen?)

5H (yes plus HK) - ?

 

Now you have to hope partner has 4H or sth good happens to the 13th S, partner being supposedly 4423 or (43)33 and shouldn't have 4D's.

 

I dunno how to ask this...
