, if an offensive player, such as the center forward, has the ball in front of the goal, and the defender cannot steal the ball, he may intentionally commit a foul. The forward then has a free throw but must pass the ball off to another offensive player, rather than making a shot at the goal. Defensive perimeter players may also intentionally cause a foul and then move toward the goal, away from their attacker, who must take a free throw. This technique, called 'sloughing', allows the defense an opportunity to double-team the center forward and possibly steal the inbound pass. The water polo referee may refrain from declaring a foul caused by a defensive player, if in his judgment this would give the advantage to the defending team. This is known as the Advantage Rule.
