A pressure is made from the left to the right.
CR is placed on the inside of the defending R1.
When CB receives the ball while running forward, she breaks and makes a pressure between the defending L2 and L1.
RW and RB crosses behind CB.
Now a pressure is made against the defense, and if CB has done her job well, she alone should have taken the defending L1 and L2 out of the defense, which should give plenty of room between the rest of the defense and - if the ball ends with LW - a numerical superiority should have been achieved.
