I can't see any basis for a normal score adjustment, because the side opening the Multi have done all that the regulations required. I suppose that if, as the Multi side, I had noticed when providing the opponents with the defence that there was a gap, I would probably have pointed it out and given them the opportunity to agree something, but that is a matter of "personal ethics". I wonder, however, whether the combination of the regulation and the fact that the agreed meaning of redouble doesn't feature in the suggested defence, has made normal play of the board impossible. We could then give both sides the good score bluejak would like to see. But this is only really appropriate if the TD is called during the auction if the dilemma is noticed. Otherwise a bridge result has been obtained, and if the opening side has got a good score, they should be entitled to keep it.
