So the opening leader lays down the ace of hearts, commenting "I bet this gets ruffed", and then comments again when seeing dummy "yeah, that's too many hearts, its getting ruffed", and then expresses surprise when I follow suit. She promptly switches to a spade, and her partner tries to cash the AK instead of switching back to a heart. Justice was done (by the way, 4 spades is making, and 4 hearts can be made, there was a club void in one of the hands).
Quick question, though - if they had used UI correctly (ie, I had 1 heart and 2 spades), at what point do I call the director? At the point they give UI with their chatter, or at the point they use the UI, or at the end of the hand?
