What is the meaning of "My hand has been played"? And is it similar to "I've been played?"
This is the context:
"How did you get my phone number?"
"...She told me your name and that you are a professor at NYU. You are listed as Dr. Martin Rose. There are 3 Martin Rose listings in the telephone directory but none with the title of Dr. There you have. My hand has been played."
