Is it Trickery when defender A passes the ball back to the keeper and the keeper flicks the ball up to the defender A who then heads it back to the keeper? I know two defenders can do this and it is normal play but I was curious if the keeper is allowed to initiate without penalty.

USSF answer (January 16, 2012):
This was one of the first tricks used when the Law was changed to do away with this sort of behavior. Yes, it is trickery.
