In Bridge, one is allowed to look at the four cards played to the last trick (if the next round hasn't started).
Can I similarly ask about cards played to the current trick?
I was sitting at East, and the third round of a suit was led by West. Declarer followed suit from dummy immediately.
I asked: "Who played the master card?" (It was West, and I didn't want to trump partner's trick.)
Dummy protested, "You shouldn't have asked that question, because you just advertised your void." But partner had already played (as had dummy). So only declarer would "benefit" from my question.
Was my question proper or not in this context? If it was improper, was it for the reason dummy said? And do I have the right to ask declarer to play in a "measured" (rather than "immediate") fashion, so I can see the cards played?
