CB runs to the left while passing the ball  to RB.
RB passes the ball to LB, who has made an initial feint and has the opportunity to shoot past CR, who is screening L3.
The pass to LB is to be made in such a way, that the shot can be performed on 1st step.
Often a jump shot will be the most effective.
If defending R3 is backing up, a center cross with RB is made and CR holds the screening.
Now RB put a pressure against the defending L2 and L3.
CB has moved to LB's position and can now move forward, receive the ball from RB and shoot.
