The rulings golfers actually argue about
My ball landed in a divot in the fairway. Can I move it to a better lie?
Play it as it lies
A divot hole is not an abnormal course condition. You must play the ball as it lies. There is no free relief unless the course has a local rule specifically covering divots.
Rule 9.1 · Ball Must Be Played as It Lies
My ball is touching a sprinkler head on the fairway. Do I get relief?
Free Relief
A sprinkler head is an immovable obstruction. You are entitled to free relief — drop within one club-length of the nearest point of complete relief, no closer to the hole.
Rule 16.1b · Relief from Immovable Obstruction
I accidentally moved my ball on the green while marking it. What's the penalty?
No Penalty
No penalty. If you accidentally move your ball or ball-marker on the putting green while marking or lifting it, simply replace the ball on its original spot.
Rule 13.1d · Accidentally Moving Ball on Putting Green
Stop arguing. Just ask.
