Advice: "Advice" is any counsel or suggestion that could influence a player in determining his play, the choice of a club or the method of making a stroke.
Information on the Rules, distance or matters of public information, such as the position of hazards or the flagstick on the putting green, is not advice.
Bunker: A "bunker" is a hazard consisting of a prepared area of ground, often a hollow, from which turf or soil has been removed and replaced with sand or the like.
Grass-covered ground bordering or within a bunker, including a stacked turf face (whether grass-covered or earthen), is not part of the bunker. A wall or lip of the bunker not covered with grass is part of the bunker.
The margin of a bunker extends vertically downward, but not upward. A ball is in a bunker when it lies in or any part of it touches the bunker.
Burrowing Animal: A "burrowing animal" is an animal that makes a hole for habitation or shelter, such as a rabbit, mole, groundhog, gopher or salamander.
Note: A hole made by a non-burrowing animal, such as a dog, is not an abnormal ground condition unless marked or declared as ground under repair.
Flagstick: The "flagstick" is a movable straight indicator, with or without bunting or other material attached, centered in the hole to show its position. It must be circular in cross-section. Padding or shock absorbent material that might unduly influence the movement of the ball is prohibited.
Hole: The "hole" must be 4 1/4 inches (108 mm) in diameter and at least 4 inches (101.6 mm) deep. If a lining is used, it must be sunk at least 1 inch (25.4 mm) below the putting green surface unless the nature of the soil makes it impracticable to do so; its outer diameter must not exceed 4 1/4 inches (108 mm).
Water Hazard: A "water hazard" is any sea, lake, pond, river, ditch, surface drainage ditch or other open water course (whether or not containing water) and anything of a similar nature on the course.
All ground or water within the margin of a water hazard is part of the water hazard. The margin of a water hazard extends vertically upward and downward. Stakes and lines defining the margins of water hazards are in the hazards. Such stakes are obstructions. A ball is in a water hazard when it lies in or any part of it touches the water hazard.
Note 1: Stakes or lines used to define a water hazard must be yellow. When both stakes and lines are used to define water hazards, the stakes identify the hazard and the lines define the hazard margin.
Note 2: The Committee may make a Local Rule prohibiting play from an environmentally-sensitive area defined as a water hazard.
Ground Under Repair: "Ground under repair" is any part of the course so marked by order of the Committee or so declared by its authorized representative. It includes material piled for removal and a hole made by a greenkeeper, even if not so marked.
All ground and any grass, bush, tree or other growing thing within the ground under repair is part of the ground under repair. The margin of ground under repair extends vertically downward, but not upward. Stakes and lines defining ground under repair are in such ground. Such stakes are obstructions. A ball is in ground under repair when it lies in or any part of it touches the ground under repair.
Note 1: Grass cuttings and other material left on the course that have been abandoned and are not intended to be removed are not ground under repair unless so marked.
Note 2: The Committee may make a Local Rule prohibiting play from ground under repair or an environmentally-sensitive area defined as ground under repair.
Rub of the Green: A "rub of the green" occurs when a ball in motion is accidentally deflected or stopped by any outside agency (Rule 19-1).
Rule 1-1 "Gimmies"
Q. What is the Rule for allowing "gimmies"?
A. The Rules of Golf do not permit the use of "gimmies." Rule 1-1 states the Game of Golf consists in playing a ball from the teeing ground into the hole by a stroke or successive strokes in accordance with the Rules. Additionally, in stroke play, if a player fails to hole out and does not correct the error prior to playing a stroke from the next teeing ground, he shall be disqualified - see Rule 3-2. In match play, if the putt has not been conceded, (Rule 2-4) the player shall lose the hole.
