Do not talk or move while a shot is being played either on the tee, fairway or green.
Do not play a shot until those ahead are out of range.
When looking for a lost ball, call the next players through, and once having done so, allow them to proceed even though you may have found your ball in the meantime.
If you are more than one complete hole behind the players in front, you have lost your place. You must give way to the players behind.
If you have incurred a penalty, indicate this fact to your opponent at once.
Walk smartly between shots.
Take your proper turn on the tee.
Replace divots, and rake out marks in bunkers before leaving them.
Repair pitch marks on greens and keep trundlers away from green surrounds and wet patches.
The removal of the ball from the hole with the putter blade is not permitted.
