Huh, I am the first one to give North blame? How can you pass with 1426 and just one defensive trick when your partner has to assume you have a weak NT?

I voted no blame.

#1 1C opening is ok, what else
#2 the neg. X is ok, we can of course talk
about 2NT being better, but the neg. X
is not bad / terrible
#3 Pass after 3S is ok
#3 the Penalty double is ok, after all you have
3 defensive tricks oppossite a opener
#4 Passing the Penalty out is ok as well, ok
you have some offense, but you are min,
and your shape is not out of space

And go to the 5 Level, which most likely converts
a reasonable plus score into minus, -500 is possible,
because partner never told you he has a fit for you?

But he may well sit on 2 trump tricks + 1 1/2 other tricks.

Expect no mercy from your teammates, if you go and
it is wrong.

I see that the panel is not willing to ascribe much blame for this result.

But here are my two cents.

Why is South making a negative double without hearts?

Here is a simple suggestion. Rather than make a negative double, bid 2 - game forcing, denies hearts, shows club support.

Now, it is not nearly as difficult for North to bid 4 over 3. And if South still doubles 4, well, that's life.

Depending how many clubs the 1C opener did
promise, e.g. for some, it may show only 2,
some people may require 5 clubs for 2S.

I am not saying, 2S is wrong, but just, that this
bid has some flaws as well.

This is an auto double of 2 Spade, even with just 3 Hearts. What else? Searching the possible 4-3 Fit in Clubs before?

After this double, North can never ever pass with his hand. This is beyond words.
He has an offensive 1426 hand, a clear 4 HEart bid.
After this bid there is still a big danger, that you reach 4 Spade doubled, but you have at least a chance to escape to 5 Club.

So 100% North.
Kind Regards

Let's explore this further.

Suppose we take the 2 card club opening bid out of the equation. Suppose the hands were:

1 - 1 - x - 3
P - 4 - x - All Pass


Do you agree with the auction? Is there any difference (other than the reversal of the minor suits) to the original hand?

Would a 2 bid over 1 be more acceptable in this auction?

Going back to the original hand. Suppose North, instead of holding 1426, held:



Doesn't North have an automatic 4 call over 3 after South makes a negative double? On a spade lead, both hearts and notrump make the same number of tricks - most often 9.

But if South cue bids rather than makes a negative double, NS get to 3NT.

I admit that the cue bid is not perfect. But it is less flawed than the negative double.

Nice hand to show why doubling is wrong. Because it is overloaded with various types of hands.

2 instead would had worked tad better: Never ask when you can show.

Anyway biggest mistake is passing twice with north's hand. I awarded him only 60%.

When partner assumes you have 4 hearts and bids some number of them at some level, what do do then? Play on the 4-3 heart fit? At least if you're working with a potential 4-3 club fit, you're not looking for a club game, you're looking for NT. I think the cue-bid is far superior to the double.

Having made the double, I think north has a clear 4 bid over 3.

Call me crazy....

but I just bid 3NT as South (or 3 if that will be interpreted as a transfer to NT). I'm control heavy for a 3NT leap, but I'm on the low end for points (12-15), so it should work fine.

Why am I playing around? Hoping that partner started with 6 clubs and 5 hearts?

Yes, because it is more likely that the 1D opener
was based on a 4 card suit.

And I would have bid 2S myself in this case.

The answer is No, 3H is enough.

Sorry, but the neg. X could just be based
on 6/7HCP, depending on partnership
agreement, which means openers 16HCP
balanced hand (which he would have opened
with 1 NT anyway) is not enough to justify
a 4H call.

And after a 3H bid, responder can bid 3NT.

PS: We had this discussion before, although the mayors
were reversed, and I know that I am fairly alone at this
forum with the opinion that a neg. X does not 100% gurantee
the unbid mayor, or more precise, I believe, that you are
able to cancel the message, that you hold 4 cards in the other
mayor.

I think the negative double either shows the 4 card major or it shows some fairly strong hand that is good enough to bid again after any support bid by opener. Opener should assume it's the 4 cards in the unbid major unless told otherwise.

I believe that 3 takes up too much space and is forcing opener to make the best educated guess as to the best contract. I think at the table 4 rates to be reasonable, whether it makes or not, because of my shapely hand with lots of offense and little defence. Maybe I'm wrong though.

Cuebid is so great?

Okay
Pd has
Kxx, AKQJ, xx, Kxx and bids what after 3 Spade comes to him? 3 NT with a singelton stopper? Because he knows that you have a running suit and/or a stopper yourself?

He has
xxx,KQJx,Kxx,KQJ and you want him to bid what? And you want to play which contract?

Yes, you will avoid some silly 4 Heart contracts with the cuebid, but with the double you have at least the chance to find some good 4 Heart contracts when NT is not the best contract. And- as long as the opps don´t intervene more- you may have a chance to show your hand type later.
Kind Regards

Do you mean the 2nd doubel?

The 2nd double is penalty.

The first was neg. and did not
deny length in their suit.
