I sent a message to Pierre Zimmermann today remembering him to register. I'm sure some of us here are also aware of other teams who will come for sure but did not register yet. It's easy to remember them to do it now. It would help the organization.

Some “big” teams such as Lavazza or Monaco are not registered yet. Can't imagine they are not coming.

In Ostend (last match) board # 5 also was a potential slam. Few bid it.
My experience is that, looking at last sessions (and last boards) of major events, you indeed can be suspicious. See last boards of the BB final / semi-final / round robin in Lyon last year, see last board of previous EBL European championship (in Budapest), see last board in Sanya, last boards at Bali BB (semi-final and final), penultimate board in Wroclaw… and many more (last board of the recent US trials !)
I would really find interesting that, taking last sessions of all European and World championships (to start with) of the past 20 years, one would compare the % of possible slams (ie. a/ 12 tricks can be made, or b/ the slam is a decent one - say 50% probability -but fails) with the theoretical number with randomly distributed deals (who knows this theoretical % ? … and the probability that the very LAST board is a slam ?)

Some statistics : you will be in a position to open a 4432 hand (ie. with opening values out of your NT range, as a dealer or 2nd seat when dealer pass, etc…) once a month if you play a 30 boards session every day. So I doubt your decision (5532 or 5542) will have a huge impact on your performance a the end of the year.
It's amusing to see that in my country (France) one of the very first questions in a new partnership still is : “do we play four-cards one diamond, or three-cards one club ?”
I'm personally convinced the Polish approach (the 5551) is best, but my partners are not !

5551 is the “original” Polish Club style. Many Polish champions (and other from former-Eastern block countries) champions play this way.

Right ! It was published only few hours ago so I did not see the other article.
At least that will give double chance to the readers !

This is also interesting to read, on the same topic.

Do you believe, then, that the IMSA should not have been created :

There has been a debate among the “Présidents de comité” who took the opinion of the “Présidents de clubs” and the players themselves. That's why we can say “ a vast majority …”

Patrick Laborde, non, la “reconnaissance d'utilité publique” est tout à fait autre chose. Il s'agit bien ici de faire reconnaître la FFB comme une fédération sportive par le ministère des sports.

You can easily enter a hand in BBO “hands played and results … editing hands”, and have a double-dummy analysis. Enter four hands, the contract, and play card by card … GIB tells you trick by trick when you go right … or wrong !

If you ask DM Pro not only if a contract makes, but the frequency of making 9, 10, 11 tricks …etc… you get a table with a comparison of both contracts (when I make exactly 9 tricks in NT, what % of hands give 9, 10, 11 …etc… tricks in Spades)

None of the opponents holds the 8 remaining spades for rather obvious reason in the bidding. So assuming East has 12 unknown cards vs. 13 is wrong but anyhow …
… I love these problems … knowing that a 3-0 break has a 22% probability (11% left and 11% right) and that these probabilities change to 12,4 % vs. 9,6% when you have 12 unknown cards in one hand and 13 in the other one, how much is - in pure maths - the “risk” of going wrong at the end of the year … ? Well, fractions of imps.
So better wait three minutes before calling a card from dummy, look at your opponent's face and see which one looks more nervous.
The hand remembers me one played by Jaïs in rubber bridge long time ago, in a similar situation (but dummy did not have the 10 of diamonds). After the lead Jaïs called “100 honors” … but none of the opponents said : “it can't be” !

The mathematical formula for these calculations is quite simple and if you are interested in making your own Excel sheet, drop me a message. It helps in understanding how probabilities change (or not …) when you get more and more information about the hidden hands.
One example : you play 5 Clubs and you want to know how often hearts are 3-3. LHO leads a spade and East follows (so both are left with only 12 unknown cards) and LHO opened a weak 2 diamonds (he has 6 cards in the suit and RHO has 3). Then the 3-3 probability in Hearts is still 33,6 % … did not change much (compared to the a priori 35,53 %) despite the fact you are down to 6 unknown cards vs. 9
And if you are convinced the lead is a singleton …etc…

In real life, if you don't bid 1D, West bids … 1D and when they reach 3NT your partner can't find the Diamond lead.
