Attacking RB has in this example the possibility to throw the ball to LB.
A pass to CB or to the opposite LW seems risky, as a defender is close to these players,
However a pass to LB player seems secure, as the defending R2 is at the goal circle.

When the pass is made, the defending R1 (who is high on the attacking LW) moves forward to catch the ball.
This action will be unexpected as the passing RB has evaluated that the defending R2 is no threat for the pass.
Defending R2 must be ready to cover both the attacking LB and LW in case the intercept is unsuccessful.
These 2 attackers will then have an easy opportunity to score.
