The wing runs quickly against the outer goal line with 3 or more steps.
Then turns around and runs against her normal place.
The nearest backcourt passes the ball to the wing, who again runs against the outer goal line with max 3 steps.
The quickly turns, perform a dribble and attack between the defending wing and backcourt.
The defending wing should at this moment be fairly baffled by all that running.
Of course the shot can be performed at any moment when the wing has the ball if a shot is possible.

And the feint can be made with 9 steps when the wing starts from the outer goal line and receives the ball close enough to the backcourt.
