user3059: Be the piece that moves away and makes a discovered check!

user2948: A queen can not start the game on a square of the other color. All other pieces can, and in fact, do.

user2525: The queen cannot not be where the queen starts when the game begins. 
All other pieces can not be where the queen starts when the game begins. 

user2953: 
A Queen cannot be captured when static by an attacking King.
A Queen cannot capture a piece more valuable than itself. 
A Queen cannot move to create a discovered check.
A Queen cannot sacrifice itself for a higher valued piece.
A Queen cannot initiate a double check.


user2800: I'll have a go at saying the queen is the only piece that cannot reveal a discovered check.
