Advancing the ball
The ball gets turned over to the defense if the attacker goes where without the ball?
Water polo
When the offense takes possession of the ball, the strategy is to advance the ball down the field of play and to score a goal. Players can move the ball by throwing it to a teammate or swimming with the ball in front of them ("dribbling"). If an attacker uses his/her arm to push away a defending player and free up space for a pass or shot, the referee will rule a turnover and the defence will take possession of the ball. If an attacker advances inside the 2-meter line without the ball or before the ball is inside the 2-meter area, (s)he is ruled offside and the ball is turned over to the defence. This is often overlooked if the attacker is well to the side of the pool or when the ball is at the other side of the pool.
