Rather than ATBing @ either, since there are numerous calls one might disagree with in this auction, can we atb to each of them individually?

 

I’ve had to make up the pips in the diagram above apart from the T98 of Hs. They might have been slightly better, though there were no other Ts around.

 

Basic system is 2/1 GF, Kokish would have been available, 2D would have been a relay rather than negative, basic cuebidding and RKCB available but not much detail in partnership agreements (we’ve played together a handful of times, but with large gaps between)

the appropriate answer to "some kind of king ask" must be 6♦. Partner will take it as either one king, or the king of diamonds. Maybe South will just bid 6 then.

I'll go with North 80% South 20%. The 2N response makes life difficult, especially if hands such as North's can be expected. North shouldn't jump to 4H with a hand that could conceivably play better in diamonds, and shouldn't jump to 7H with no real reason to believe there's 13 tricks.

2♣ 10%

2NT 5%

4♥ 25%

7♥ 60%

2♣ is horrible, 2N is worse.

 

Somebody has spades, the bidding will not die in 1♥, you might bid 2♣ as a preempt to shut out the spades, but I'd open 1♥.

 

If you play 2♦ relay and this doesn't fit your view of a 3♣ bid, then bid 2♦. If you have the arrangement that this is say 10-12 no singleton and no HHxxx, I can just about live with it.

 

4♥ to my mind is the solid suit bid which you don't have.

 

Using 4♠ ace asking rather than 4N is clearly superior here as the auction now proceeds 5♣-5♦-6♦ and N has shown all his high cards.

 

If N's hand is a 2♣ opener in system, then S should be more cautious, 7♥ is then a gamble rather than barking mad. If partner isn't going to expect this sort of hand, he may overvalue his own hand slightly and expect you to have Q♦ as well (possibly and an 8th or 9th heart).

 

Whenever opps bid like this against me, partner leads a club, they're 4-3 and the Q♦ drops :(

Yes. This grand is only antipercentage if we are the ones who bid it.

While there are certainly many calls in this auction that one might disagree with (in fact, there are few calls in this auction that I would agree with), the basic principal is that you do not bid a grand slam unless you can count 13 tricks. Here, there is no way that North could count 13 tricks on this auction armed only with the information that South had some sort of positive response to his 2♣ opening and that the partnership was in possession of all of the aces.

 

So, while there is a lot of blame to go around, the final jump off of the cliff belongs to North, and he gets the blame.

 

Assigning the blame on this hand is a lot like trying to answer the question "What caused World War I?" Everyone points to the assassination of Archduke Ferdinand of Austria as the event that triggered WWI, but there were so many other things that contributed to the war that the assassination was just one small event in a series of much larger events which caused the war.

[HeartA]

195% to North. 95% for 2♣opening, 100% for 7♥. 5% for 2NT response.

We're gonna need a bigger boat.

Hi,

 

#1 2NT is a nice bid, although I prefer to have at least a minor honor in every suit.

#2 4H is ok, as long as it says, I have a min 4H bid

#3 4NT is certainly ok, I have 2 KC, and the jack, so slam should have play

#4 5D ok

#5 5NT makes it clear, that the partnership has different meanings about the 4H bid

if 4H showed min values, one should be content with 6H, having a min as well,

if it showes more, than I dont see the add. values in the North hand.

 

So the ATB should be around, who is right, what 4H showes / not showes.

 

With kind regards

Marlowe
