Scoring: MP

The board whizzed by in 30 seconds.

North South
Pass - 1♦
1NT - 3NT
all pass

Robot North plays out the board in 20 seconds for +520.

In last night's Robot duplicate, no pair managed to reach slam (not even the 6-level). Any idea how these can be bid to a grand slam?

What does 1♦-1NT-3♣ show in GIBberish?

[Codo]

Does 3 NT show this hand?

[ONEferBRID]

Definitely not standard, but my home grown system:

♠ A2
♥ 95
♦ QJ4
♣ QT8762

♠ T7
♥ AT
♦ AK8653
♣ AKJ

p - 1D
1NT - 3C! ( GF, maybe artificial )
3H! ( relay ) - 3S! ( completing relay )
4C! ( double fit: 3+d / 4+c ) - 4D! ( 6 Ace RKC )
4S! ( 2nd step = 1 key ) - 4NT! ( Q's ask )
??
5C! = neither Cl or Diam Q
5D! = 1 Q
5H! = 2 Q's

5H! - 5S! ( specific K-ask; either Major K enough for the grand )
6C! ( no K's ) - 6NT ( can only count to a sure 12: 1s, 1h, 6d, 4c )

Yay for jump shift into suit shorter than 4 cards!

[ONEferBRID]

More conventional:
p - 1D
2C ( 5+c, values, no 4M ) - 2H
2S - 4C! ( Minorwood )
4H! (2nd step = 1 key ) - 4S! ( next step = cQ-ask )
5D! ( cQ and either dK or dQ; denies hK or sK ) - 6C ( not sure how many Diam will come in--may need to ruff a Diam to set up )

I wonder which meaning of the word "conventional" you meant to convey here.

1D ,2C (shows diamonds values and secondary club suit and maybe 8-10HCP - if partner is subopening- one suit has got to be right so not forcing), then same as Oneferbid bidding sequence except 7NT at the end is easy as partner is known to have QD and QC and AS at least.

[Flameous]

1♦ -1NT -
3♣ - 4♣ -
4♦ - 4NT -
5♥ - 7NT

3♣ ostensibly natural, but includes hands like above.
4♣ good clubs and slam interest
4♦ showing great hand with primary diamonds. (2 clubs only when 7222, otherwise 3)
4NT 6 key RKC
5H 2 or 5 without either Queen.
7NT lol, you can't have 2 aces for this bidding

Natural did better this time than my relay methods:

2♣ - 2♦ -
3♣ - 3♦ -
3♥ - 3♠ -
4♣ - 4♦ -
4♥ - 4♠ -
4NT

2♣ natural clubs, may have ♦s
3♣ shows the shape
3♥ 5 AKQ points
4♣ even number of kings and no ♣ control
4♥ No ♦ control
4NT No ♥ control

So now ♠A is known and that there are two queens. Problem is that 5♣ relay would take us to 5♥ minimum. I think it's strongly odds on that there is at least one minor queen but do you want to play 6 then? But if there are 2, you wanna play 7NT. Now that I think of it bit more (probably wouldn't come this far in table) it's possible to stop in 5NT after no minor Qs. So I guess it's good to relay once more... and you get it all.

5♣ - 5NT = ♠A and minor queens - 7NT

[gwnn]

Would

AQ
QJ
Jxx
xxxxxx

really be an opener for you? and how likely is that hand?

[Flameous]

Well at least if it's JT of clubs it's automatic. (Can't be here) But this is in strong pass/ club context- Wouldn't open natural one club. That tends to lead to trouble.

Mainly I though about AQ xx Qxx xxxxxx being a possible problem.
