When screening an opponent, what must the screener allow if the opponent is stationary?

When screening an opponent, the screener must allow the opponent who is stationary the ability to take one step toward them. This rule is in place to ensure fair play and to provide the defender a reasonable opportunity to move and respond to the actions in the game. By allowing the stationary defender a step toward the screener, it equalizes the positioning and prevents the screener from impeding the opponent's ability to defend effectively.

If the screener denied this movement, it could be considered an unfair advantage, as the defender would be unable to adjust their position or maintain an effective defensive stance. The other choices do not align with the established rule; for instance, allowing two steps backward or any amount of space for movement would not reflect the necessary balance between offensive and defensive play in the context of a screen. The rule emphasizes that while screening is an important offensive tactic, it must not be executed in a way that completely restricts the opponent's movement or ability to defend.
