A "bogey" occurs when a player requires one stroke more than par to complete a hole. So, if you finish a par 4 in three strokes, you make a "birdie," but if you take five strokes, you make a "bogey." The "bogey" score is used instead of the actual number of holes played because not all players use hoses on their golf balls. A golfer who uses a hose will be able to play faster and still keep his or her score within range of par. Thus, the "bogey" system was created so that everyone has an equal chance of winning. The first two rounds of most tournaments are called "qualifying rounds." These are official events where the field is cut down from the maximum number allowed to play. The third round is usually called the "playoff round" and it determines which players have qualified for the next stage of the tournament. In fact, the term "playoff" comes from this use of the word round. The "cut" is the amount of money each player must pay to enter the tournament. This amount varies depending on the prize structure of the event but is usually between 10% and 40% of the total cost of entering the tournament.
