A friend reported this hand from a social game and wondered if there is a 'scientific' way to bid the Grand Slam?
North. ♠65, ♥K7, ♦AQ64, ♣AKQ98
South. ♠AJ2, ♥AQJT9, ♦KJ9, ♣73

Suggestions would be appreciated.

suspect many auctions would be like 1NT-2♠;2NT-5NT; 6NT or even 1NT-5NT; 6NT

tough...if south is dealer



1h=2c(gf)
2h(6, can be very minimum)=3h(slam try)
4s(rkc)=4nt(0-3)
5d(confirm all kc...KD, grand try)=?


one spade


6h


3d at least...



3 clubs at least

again note 2h shows 6h and can be really minimum.

even harder if north is:



I will start;
1c=1h
2d=2s(art and game force...9/10+hcp)
3c(deny 3h or 4s often)=?

fwiw I play a pretty old fashion strong reverse style...but given the forum which prefers light reverses....tough.........

1♣ - 1♥
2♦ - 2♥
3♥ - 3♠
4♣ - 4NT
5♦ - 5♠
7♣/♥ - 7♥

2♥ = Forcing , 5+♥
3♥ = 2 card support (often Hx) , no ♠ stopper
(We bid 4♥ or 3♠ with 3 card ♥ support).
3♠ & 4♣ = cuebids for ♥ (perhaps unnecessary..)
4NT = RKCB 1430
5♦ = 0/3
5♠ = asking for Kings,showing all 5KC present , inviting grand(you can use 5NT if you prefer)
7♣/♥ = I have a source for tricks and extras - should be enough.

Does it look reasonable, or too optimistic?

It is very common in "modern" bidding for
1♣ - 1♥
2♦ - 2♥
to be played as forcing (for 1 round) , using 2♠ or 2NT for weak hands.

Yes, you cant stop exactly in 2♥ (some people would respond 2♥ on the 1st round with that hand) , but you get much more flexibility with developing your auction, when 2♥ is forcing.

No real need to get scientific imo.

1♣ - 1♥
2♦ - 2♠
(something - 3♠)
something - Blacky
something - K ask
something - 7♥/NT

Opener shows 18+ without a ♠ stopper, so he must have pretty much the rest (especially if you keep asking with 3♠). Once you know about all Aces and every K except ♠K the grand slam is pretty obvious imo.

I would never get there using (my) relays. N wouldn't find out about the heart J in time. So I am thinking I wouldn't get there without relays either :huh:

in the relay system that I used long ago
1C-1H
1S-3D
3H-4D
4H-5D
5H-5N shows Axx AQxxx Kxx xx without the ♠Q and uncertain jacks and we agreed that 6 level bids are never relays. tough luck, we are in 6NT and it's even wrongsided. oops.
... and I can prove it with my usual, flawless logic.

1♣-1♦ (same as 1♥)
2♦-2♥ (GF relay asking distribution)
2NT-3♥ (2245, 3♥ sets trumps)
4♣-4NT
5♦-5NT

at this point north can count 12 tricks ♠A, 6♥, ♦A and 4♣ with a likelly 13th in ♠K, ♦ finese, ♣J, lucky club break, 7th ♥ or ♦K

I think he should blast to 7♥ althou just showing ♣K might be even better since south is bidding 6♦ and now maybe 7NT comes into picture.
