Learn how golf tournaments work. Tournaments begin with a large number of players, and it takes a long time for the golfers to make their way through the rounds. By instituting a cut line, spectators and other contestants can focus upon the players who are most likely to win the tournament.
Look at the standings until you get to 70th place. The cut line in the big, professional tournaments usually stands after the 70th place. The cut could be different, however, depending on the tournament. If it’s a smaller tournament, the officials may put the cut in a different place.
View the course’s par number. Par is supposed to be the number of strokes it takes for an average player to make his way around the course. Under par means below average, so the cut may simply be the par number to start with.
Formulate the projected cut by applying this formula: Find out the cut from the first round of the tournament, then double it (the players are going around the course again, after all) and knock off one of the shots. If the cut was 70 on the first day, you would expect the best players to do better, not worse. So you double the first-day cut (140) and take off one shot. This makes the projected cut 139. The official cut may change at the end of the day, depending on how players are doing as the tournament progresses.
Restrict the field to players within 10 shots of the leader. This allows you to concentrate on the best players. It also provides motivation for the other players, as “making the cut” is a big deal and embarrassing if not accomplished.
