EW haven't played together before, but they've discussed their system, and are playing Acol with a 12-14 NT, multi-2♦ and Lucas twos, opening one-bids all show at least four cards in the suit.
When East bid 2♦, West announced "transfer to hearts". East immediately said words to the effect of "How can that be a transfer?", and West corrected his mistake.
North called the director, and asked for a ruling. The TD told East he shouldn't have said anything, and ruled that all comments by East and West (the announcement and the comment by East) were unauthorized information and care had to be taken to avoid taking advantage of them, and asked them to continue playing.
West made 10 tricks on the lead of ♣10 for a loss of 1 IMP (against 3NT+2 at the other table).
What should the TD do at the end of play? Do you see any reason to award an adjusted score?
Under EBU regulations (which the club follows), transfers to the majors are announceable only after 1NT and 2NT opening bids and an intervening pass. Other transfers would require an alert, but I doubt these two players have even heard of playing transfers over suit bids.
