What happens when a player fails to adhere to a foot-fault warning and disturbs the head?

When a player does not comply with a foot-fault warning and subsequently disturbs the head, the rules allow for the opponent to make a decision regarding how to proceed with the head. This means the opponent has the option to either have the head reconstituted as closely as possible to its position before the disturbance or to play from the disturbed state. This rule is designed to ensure fair play and to give the non-offending player control over how the game continues after an infraction that directly affects the state of play. By empowering the opponent to choose, the game maintains its integrity and allows for a resolution that reflects the natural flow of play, despite the fault committed by the offending player.
