According to the rules, when can a player seek advice from someone other than their caddie?

The correct answer is that a player can never seek advice from anyone other than their caddie during a round of play. This rule is in place to ensure fairness and maintain the integrity of the game. The essence of the rules of golf is to promote self-reliance and resourcefulness among players.

Under the Rules of Golf, advice is defined as any counsel or suggestion that could impact how a player plays their next shot, including the choice of club or strategy. The only person from whom a player can receive advice during a competitive round is their caddie. This limitation fosters an environment where players must rely on their own judgment and skills, aligned with the spirit of the game.

Regarding the other options: while spouses or certified coaches can provide support outside of formal play, their input is not permitted during the active round. The focus within the competitive context remains strictly on the player and their caddie, ensuring a level playing field for all competitors.
