But North is complaining that he wasn't be hearing by East from the start of the match, that East lost courage to admit
his absence and his misunderstanding of auction. Why North's guilt is bigger than East's one in the fact of no written exchange with no paper available ?

For what reason do you think that
N did not explain his partner's bid
E could not forgot his system ?
Why this preference ?

It is not strange to me, you're lucky to find 8 cards fit or better. Especially after the double, passe shows that very well.

The CoC weren't respected by TD, it didn't make easy for players. The composition of committee was known so it was easy to make quickly the 3rd one, but TD denied that procedure.

There is no difference between regulations required.
Only your partner forgot his CC after the 4th round and when you are back to the play area from lunch, his CC is not found. And TD asks you to play the 5th round without putting any paper on tables. You give your CC to the opponent on the other side of the screen, because your screen-mate is not interested by.
Do you think it's enough to refuse to play bridge as you're asked to do ?

Without spontaneous alert of 2H I can't see ruling in favor of NS

I agree totally with your way of doing !

What's CoC, please?

let us protest together:))

Well, I bid 5C, never 2NT. I don't want the auction room open for opponents.

Easy, too easy, he did not make his job for sure !
Anyway the players involved need more then such evidence.

The competition dured two days, six matches of 130 minutes each.

The CC was on the other side of screen, but E could ask for that and he did not. Nor he didn't listen his screen-mate explaining the system.
And there was no paper on tables !!!
I know, it's hard to believe, never seen that before.
It's the reason I'm talking to you about.

Hendrik, there were two committees before that problem, there was no reason to refuse one more espescially at crucial moment, but TD did.

Michael,
Really a plesure for me to read you! Maybe after a good night I'll be more clever to follow your mind. Now too tired, sorry and good nigth to all of you ♥

let him stay there for longtime!

very probably I misunderstood your message, please don't be angry, my english is poor.

How long will you hide your system to your opps ?

John, thank you for your large commentary, I need more time to answer to you about. Only I can tell you that same players played 12 boards against same opponents two weeks earlier.
