Rule 4: Guarding is the act of legally placing the body in the path of an
offensive opponent. There is no minimum distance required between the guard
and opponent, but the maximum is 6 feet when closely guarded. Every player is
entitled to a spot on the playing court provided such player gets there first

bending his/her body into other than a normal position;
