Damaged or self inflicted damage?
South opens 2C, alerted and described as 'big hand' (or words to that effect)
West overcalls 2H, North Bids 2S. and the bidding staggers on until N/S reach 5D.
East holds AQxx spades (over N) A clubs and Qxxx diamonds (under S).
It turns out that N/S had recently changed their system to 2C = 'Big OR weak 2D.
North had forgotten, and hadn't amended his convention card.
South had a corrected CC. And surprise, surprise did have a weak 2D!
5D was defeated by 4 tricks. East called TD and claimed mis-information and said he would have Dbld.
It seems clear that E/W have been mis-informed, and thus damaged.
The Director adjusted the score to 5DX -4.
However NS contended that East is the architect of his own misfortune.
And it is difficult to see why East didn't double anyway.
He seemingly has 3 or 4 tricks, and his partner has bid, but he wasn't a strong player.
Is there any provisions within the Laws to cover NS contention?
