Thanks for the replies. To try and clarify a couple of points (or admit not knowing the answers): - I don't know if the director offered to allow a change to the opening lead or the bidding - E-W had no issue with the lead or wanting to change it (I think it was a trump but certainly was not AC) - the defence to 2SX was not optimum, as you have inferred - East was claiming that he might pass if he had been given the correct information - X was still for takeout if 2D did not guarantee spades It felt to me, although I didn't state it in my original post, that E-W were seeking redress based purely on them having got a bad board through bad luck and/or bad judgement and/or bad defence as opposed to anything to do with the incorrect explanation. However, I am very interested in views for my own interest and learning.
