Israel , Teams KO match, 1st half , Top level event , played with screens (East and North are screenmates). EW are experts.
East explained to his screenmate :
4♠ = Exclusion KCB.
Pass (after North's double) = 1 KeyCard.
6♥ made easily - West did have 2 KeyCards and a ♠ void , so there was only 1 keycard missing.
NS called the director and said there has been a hesitation on the West/South side of the screen before returning with 5♥.
They suggest that the raise to 6♥ was suggested by the hesitation.
East explained his raise along the lines of : "I had a very suitable hand , and was sure my partner would have 2 Keycards to bid Exclusion KCB".
When director tried to establish the facts , he also was informed that on the S/W side of the screen West explained that "Pass" showed 0 or 3 KeyCards. It was also suggested , that West made this explanation speaking (instead of writing) , and it might have been overheard (that was not confirmed).
1. Well, what do you really think happened? Do you believe East's reasoning for his raise?
2. How would you rule as a TD, or AC member?
3. Eventually , one team won the match by a large margin, so the result of this board didnt matter. No ruling was given (I think) , and no appeal was held.
Would you pursue the issue further (as a TD, as the opps , as a random kibitzer..) ? Do you think East should face some disciplinary/ethical body, and explain his actions?
