Unless the regulation states otherwise, acts done "during a round of 18 or fewer holes played in the sequence prescribed by the Committee" do not include those taken when play is halted under Rule 5.7a. For the sake of this rule: "During" means at any time before the next scheduled start of play.
Thus, if there is a sudden thunderstorm with heavy rain and lightning that stops play on the first hole, the pro can take appropriate action (move some of his or her things out of the way, close some gates, etc.) without violating this rule. However, if there is more than one round of play that day, he or she could not leave the course without violating this rule because it would prevent him or her from finishing the round later in the day.
Similarly, if the pro leaves the course for any reason other than to finish the round, such as to get food or drink, he or she has violated this rule.
However, if he or she returns before the end of the next round, then there has been no violation of this rule.
This rule applies only to actions taken by the pro. An amateur can take any reasonable action during a round, including moving objects off the golf course, without violating this rule.
A "round" is normally comprised of 18 holes played in the sequence specified by the course layout. On a regular 18-hole course, each hole is played once in the round. The game can be played by any number of individuals, however a normal group of 1-4 people will play the round. If you happen to be the only person playing the round, then you would play all 18 holes.
Golf is most commonly played during daylight hours, which is why you see many golf courses with lights. Some courses are designed for night golf while others are not. Either way, you should notify the club before you play whether or not nights are a possibility. Most clubs allow you to use a flashlight, but some don't. You should also let someone know where you are going and when you might be back.
The objective of golf is to hit the ball into the fewest number of holes possible. This is done by getting the ball as close as possible to the place where you want it to go. Then, on your shot, you add what is called "golf swing" to get the ball in the hole.
There are different ways to hit the ball. You can use a driver, which is used for long shots; a fairway metal, which is used to hit balls that are closer to the hole; or a putter, which is used for putting.
If made during a round of at least nine holes, with the exception of a hole in one made during a match, which should be valid even if the match ends before the necessary round is finished. A hole in one made in a practice round in which the golfer is playing two or more balls should not be permitted if the player is only playing one ball.
Section 5-2 (c) of the USGA Handicap Manual addresses nine-hole scores, stating: (ii) At least seven holes must be played. There is no limit to the amount of nine-hole scores that can be recorded on a player's scoring record. Even if a golfer mostly plays nine-hole rounds, he or she can still use a handicap index.
