If external forces cause a ball to move, how should the player react?

When external forces cause a ball to move, the player should replace the ball without penalty. This is in accordance with the Rules of Golf, which state that if a ball moves as a result of an external influence (such as wind, water, or an animal), the player must replace the ball to its original position. No penalty is incurred in this situation because the movement was not a result of the player’s actions.

Choosing to play the ball from the new position would not comply with the rules, as it would disregard the requirement to restore the ball to its original location after it has been moved by an external force. Also, checking with the opponent or assessing whether to take a penalty isn't necessary in this case because the rules are clear on how to handle the situation. This emphasizes the importance of understanding the applicable rules of the game to ensure fair play.
