Scoring: IMP
The auction was:
South:West:North:East
2♥(1):pass(2):3♦(3):pass(4)
pass(5):dbl :pass:3NT
all pass
(1) Not alerted. Described on card as "6♥ 5-9hcp can be 5♥ & weaker at fav vul".
(2) Picked up NS convention card, studied it in detail, huddled and then passed.
(3) Not alerted and not documented in NS's convention card or notes.
(4) Huddled and then passed.
(5) Huddled (was trying to decide if 3♦ was forcing and took advantage of the AI of EW's huddles to conclude that this was EW's hand). Immediately after south passed east says "If I'd known 3♦ was non-forcing I would have bid" and calls the director.
The director firstly admonished east for making the verbal comment that she did and instructed west to be careful not to take advantage of this or any other UI. The director then ruled that the auction continue and EW duly bid and made 3NT with a couple of overtricks.
NS called the director back to the table to argue that passing out 3♦ was a logical alternative for west.
EW made a counter argument that if they had known 2♥ could be so bad and that 3♦ was non-forcing they would've easily bid to 3NT.
How would you rule?
