E/W were annoyed at the lack of alerts. N/S explained that they had no agreement to play 2♣ as anything but natural, North merely decided on the spur of the moment that 2♣ then redouble would be best. The redouble was for takeout and therefore alertable: South knew it was for takeout but "assumed it was not alertable because everyone plays it as takeout". E/W did not seem so sure that redouble would normally be takeout.
Important question (for this hand).
(1) Might EW have done anything different if 2C and the takeout redouble had been alerted. Answer: seems unlikely.
(2) Did N take any improper advantage of the failure of S to alert 2C or XX? Can't see any.
So no damage, no adjustment. But no criticism on EW for calling the director.
General questions (not resulting in any damage on this hand).
(1) Should the XX have been alerted. Yes. Unquestionably. That's how English alerting rules work.
(2) Should 2C have been alerted. Much more difficult. Bidding something then redoubling it to mean "anywhere but here" is a well-known maneouvre. Is this an agreement or common bridge knowledge? Is one expected to alert every bid in wriggle-out situation to say "we have not made any specific agreement over this sequence, but sometimes players are known to bid fake suits and redouble them for rescue in this kind of sequence"? I think provided S is going to take the suit as a real suit, and N doesn't do it very often, then I don't think there is a strong argument for alerting it, because EW aren't really going to take any action in advance of the redouble if N only does it rarely. If N does it regularly, then I think you have to start alerting it, as EW may then want to take pre-emptive action.
