North bids 3C without asking about the alert
South asks about the alert of 2H at her next turn and is told that it shows a sound raise to 2S, typically 7-9 with a 3 card raise.
North now bids 4H. This makes 10 tricks (It's either 10 or 11 depending on how you defend). 3S would make 9 tricks.
All players at the table are of a good standard.
EW call the director. The director rules that North is in receipt of UI but the question does not indicate anything about either values or hearts. He confides to EW that the people he consulted were not unanimous about this. EW appeal.
How do you rule in appeal?
