Grand

[hv=d=e&v=b&n=sk652ha43dqjckt53&s=shk6dak7532caq642]133|200|Scoring: IMP

At our table, opps bid to 6♣ and we still lost IMPs.

Only 8 of 14 tables bid to 6♣, the others were in game.

The grand slam is cold - is it easy to bid?[/hv]

not really you need some leap of faith:

 

1♦-1♠

3♣-4♣

4♦-4♥

 

at this point the only way I think where you can not get messed by the spade void in partner's suit is by assuming 4♥ is ♥A and not singleton and jumping to 5NT (GSF).

[Flameous]

If partner tends to prefer supporting diamonds here with 3 instead of clubs and rebid a good 6 card spade suit, it points to the direction that 4H is indeed the ace. 5125 is pretty much the only shape where it's singleton.

 

But it's indeed hard slam to bid cause no RKC takes you there. Except maybe if responder bids 6 keycard rkc over 4D and gets 5NT response (3 and void), although still it isn't certain it's that spade void...

 

With any relay precision I'd have zero trouble with this though.

[JLOGIC]

If you jump shifted I think the auction should go:

 

1D 1S

3C 4C

5S

 

With the south hand I am always forcing to slam after 4C. On a bad day we might be off 2 keycards but if partner has 2 keycards we can bid a grand easily and it seems like the best way to find out about it, since we're rarely off 2 keycards anyways and might be on a hook in that case regardless.

 

I would not jump shift though. The auction is very unlikely to die in 2C, and when we next bid 3C it describes our hand well (5-5 16/17ish) and doesn't risk getting too high on a misfit. I would jump shift with Kx of spades instead of hearts for sure though.

 

So..

 

1D 1S

2C 2H

3C 4C

 

Now for sureeeee south can bid 5S, partner showed a GF over a 2C rebid lol.

[Cascade]

1D 1S

2C 2H

3C 4C

 

Now for sureeeee south can bid 5S, partner showed a GF over a 2C rebid lol.

Yes very easy on this auction which is semi-normal if you can bid exclusion in partner's suit and why not!!!

1d normal

 

1s normal

 

3c normal too big a position to bid 2c because auction might not die there. Especially at imps.

 

3h most flexible. we do not really know much about openers hand yet and this leaves some room for further exploration and has the advantage of denying 3+ dia support. There is no guarantee opener has 4+ clubs. We have seen many hands where opener has something like AQx x AKxxxx(x) AQ(x) and has to create game force with a fragment. 3h bid at least allows them to bid 3s safely. Raising to 4c here fails to recognize many of the problem hands opener might have. If I get lucky opener can bid 3n then a 4c bid will show my slam interest and a cue bid of heart ace.

 

3n it's either that or 4c since responder still has not promised anything beyond 6 points. 3n might be last makeable spot opposite say Axxx xxxx Qx xxx or Axxx xxxx xx Kxx.

 

4c now the delayed club support shows slam interest and pinpoints the earlier 3h bid as the heart A. We now know opener has at most a doubleton spade and a max of 3 hearts and therefore is much more likely to have a real club suit.

 

5s since we know responder has the heart A and at most 2d it is now perfecly safe

to use exclusion BW with no risk.

 

6d 2 keys w/o club q.

 

7c good enough for me if 7n makes my bad.

Is partner supposed to know to go beyond 6♣ when he holds just the ♣K?

 

I have a similar, but not as strong, problem with 5♠ exclusion RKCB. Is partner supposed to know that he is to go beyond 6♣ with 2 key cards outside of spades? I suppose the answer to this is yes, otherwise the 5♠ bid was wrong.

Here's my "semi-normal" scheme ( ... some might say abnormal ):

 

1D - 1S

3C! ( GF, maybe artificial* ) - 3H! ( relay to 3S!** )

3S! - 4C! ( double fit, 3+d **/ 4+c )

??

   4D! = 6 Ace RKC ( ♣ & ♦ )

   4H! = 6 Ace RKC, Excluding hA

   4S! = 6 Ace RKC, Excluding sA

 

After:

4S! - 5H! ( 4th step = 2 + 1 Q )

7C

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

* If 3C! was artifical, it means Opener has a long Diam suit and needed a GF bid rather than a non-forcing 3D-jump rebid.

 

** If Opener rejects the relay to 3S! by bidding something else instead, say 3NT or higher, then only long Diam and no real Cl suit .

 

*** Surely one can excuse showing a 3 card Diam fit with Q J bare .

That's pretty nice, but:

- there's no real double fit (only 2♦).

- in another thread you complete the relay to 3♠ with a 6♦-3♣ (auction after 1♦-1NT however). Does it promisse 4+♣ here or can it also be 6-3?

But what a nice 2 cards: Q J

 

Opener may still accept the relay w/o a true 2nd Cl suit in order to find out more info. He can always sign-off in his top suit ( Diam here ). He's in charge.
