Table result 4♥=W, NS-420.
2♥ is alerted and explained by East as spades and a minor. The correct explanation is weak with both majors. East had misread the bid as 2♠.
X is undiscussed.
2NT is alerted and explained by West as a game-forcing enquiry. Opposite a 2♠ opener, 2NT would have been Lebensohl-like. After this explanation, East woke up to his mistake and the TD was called. After North was provided with the correct explanation of the 2♥ bid he was given the option to change his double which he declined.
1) Is it UI or AI to East that West has opened 2♥?
2) Do you adjust the score?
