The circle runner can - no matter where she is placed - use a short explosion-like move to free herself in that moment where the defender's attention is elsewhere, or a short but not so fast a move in a numbering majority where there is a hole in the defense in order to receive the ball or create a hole for an attacking team-mate.
The short acceleration can also be used when a defender next to the circle runner moves forward to block a shot or a playing possibility. This short moment can be used to take advantage of the free space behind the defender.
In order to make use of the short accelerations the players must learn to move at the right moment and with the correct speed to prevent the defenders to have the time to close the gab in the defense.
