Yielding fair access

1) Standing still. If a player attempting to play a ball is interfered with by an opponent, who, after his side has played the ball, was perfectly still in front of or aside the player, it is NOT a hinder. This “legal” hinder is the essence of the one-wall game. However, if a player of the side that has just hit the ball stands perfectly still, but his opponent moves back into him in trying to play the ball, not necessarily making contact, and is thus kept from having a fair chance to play the ball, it is a hinder. It is the duty of the player farther from the wall to get out of the way. (See Interpretation No. 12)

2) Being moved into the ball. If a player on the side that has just hit the ball is moved or pushed unintentionally into the ball, or prevented from getting out of the way of a ball, by an opponent trying to play the ball, it is a dead ball hinder.
