The two squares are split by a strip in which an attacker and a defender start
The attacker must be played into this lane by his/her team-mate who dribbles into it
The defender tries to prevent this
The attacker who is played into the lane can rebound or turn on the ball
The defender in the box is only allowed to defend in the box and in the front part of the pitch
The defender in the second box may only defend there
In this way, getting free in a small space, shielding the ball, rebounding under pressure, opening up under pressure and playing out a 2vs1 situation are trained
When the defenders take the ball away, the 2vs1 situation changes into a 2vs2 situation and everyone can come into all the squares
The defenders can then make a point by scoring in the opponent's goal
