The 'SI' on a golf scorecard stands for Stroke Index. Each hole on a golf course is given an SI number between 1 and 18, with 1 being the most difficult and 18 the easiest. The Stroke Index is used to assign handicap strokes to golfers in handicap rounds. It is also used to determine how many shots a player must give to their opponent in a handicap match play game.

What You'll Learn
SI indicates the relative difficulty of each hole
The stroke index (SI) on a golf scorecard indicates the relative difficulty of each hole. Each hole is assigned a unique SI number, typically ranging from 1 to 18 on an 18-hole course, with SI 1 denoting the most challenging hole and SI 18 representing the least challenging. This numbering system is not based solely on hole difficulty but also considers matchplay and fairness to golfers of varying skill levels.
The stroke index was designed to enable handicap match play, allowing golfers with different handicaps to compete against each other. In a handicap match, the player with the higher handicap will give shots to the player with the lower handicap on specific holes as determined by the stroke index. This helps to balance the playing field and ensure a fair competition.
While it is a common misconception that the stroke index ranks holes purely by difficulty, it is important to note that other factors are at play. For example, it is rare for the 1st, 9th, or 18th holes to have a low stroke index, as these holes are considered crucial in the event of a tied match or playoff. Additionally, the allocation of stroke indexes takes into account the need to distribute shots fairly among players of different skill levels.
The stroke index on a scorecard is used to determine where a golfer's handicap gives them an advantage. For instance, a player with a handicap of 12 would receive a stroke deduction on holes with stroke indexes from 1 to 12, while a player with a handicap of 24 would receive two strokes on holes with stroke indexes from 1 to 6 and one stroke on holes with indexes from 7 to 18. This adjustment ensures that golfers of varying skill levels can compete on a more level playing field.
The stroke index system also influences the scoring in Stableford competitions, where points are earned based on each golfer's net par for the hole. In this format, the stroke index aligns more closely with the ranking of holes by difficulty, irrespective of the hole number. This further highlights how the stroke index system adapts to different competition formats and considerations beyond simply ranking hole difficulty.

SI is used to assign handicap strokes
SI, or stroke index, is used to assign handicap strokes in golf. It is a numbering system that gives each hole on a golf course an SI number between 1 and 18, with 1 being the most difficult and 18 the easiest. These numbers are listed on the scorecard or somewhere visible and are used to determine how many handicap strokes a golfer receives on a specific hole.
The stroke index takes into account the difficulty of the hole and the player's handicap to assign handicap strokes. For example, in a handicap match play competition, if one player has a handicap that is eight shots higher than their opponent, they will receive a handicap stroke on holes with a stroke index of 1 to 8. This means that they will get one stroke deducted from their score on those holes.
The number of handicap strokes received by a player can also depend on the type of competition. In Stableford, par, and bogey competitions using stroke play, an even distribution of strokes is not as important. In these cases, the most difficult hole is usually given an index of 1, and the easiest is indexed as 18. The allocation of strokes must take into account both match play and stroke play formats.
It is important to note that the stroke index is not the same as the hole number, and it is also rare for the 1st, 9th, or 18th holes to have a low index due to their importance in the game. Additionally, it is recommended that Stroke Index 7, 8, 9, and 10 are not allocated to adjacent holes to avoid giving a player with a handicap of 10 shots an advantage on at least three consecutive holes.
By using the stroke index to assign handicap strokes, golfers of varying skill levels can compete on a more level playing field, as the handicap strokes are designed to balance out the differences in skill and ensure fair competition.

SI is used to determine how many shots one player gives another
The stroke index (SI) is used in golf to determine how many shots one player gives another. It is a numbering system that assigns each hole on a golf course a unique number, typically from 1 to 18, indicating the hole's difficulty relative to the others. The most challenging hole is given the lowest number, usually 1, while the easiest hole is assigned the highest number, typically 18. This system is in place to facilitate handicap match play games and to determine how many stableford points a player has scored on each hole.
When players with different handicaps compete in a strokeplay match, the number of shots the player with the lower handicap gives to the player with the higher handicap can be determined by subtracting the lower handicap from the higher handicap. For example, if one player has a handicap that is eight shots higher than their opponent, they will receive a handicap stroke on the holes with stroke indexes 1 to 8. This ensures a fair competition among players of varying skill levels.
The stroke index is also used to determine the distribution of handicap strokes in Stableford, par, and bogey competitions. In these competitions, the need for an even distribution of strokes is less important, and the stroke index may be aligned with the ranking of holes by difficulty. Handicap strokes are deducted from a player's score in the order of the stroke index, starting from the most difficult hole. For instance, a player with a handicap of 12 would receive a stroke deduction on holes with stroke indexes 1 to 12, while a player with a handicap of 24 would receive two strokes on holes with stroke indexes 1 to 6 and one stroke on holes with stroke indexes 7 to 18.
It is important to note that the stroke index is not solely based on hole difficulty. Other factors, such as the desire to avoid giving an advantage to a player with a higher handicap on crucial holes, also influence the stroke index allocation. Additionally, consecutive holes with high stroke indexes are avoided to prevent a player from receiving strokes on multiple consecutive holes.

SI is used in Stableford, par and bogey competitions
SI, or stroke index, is used in Stableford, par, and bogey competitions. In these competitions, stroke index is aligned with the ranking of holes in terms of playing difficulty, irrespective of the hole number.
Stableford is a scoring system used in golf. Instead of counting the total number of strokes taken, as in regular stroke play, it involves scoring points based on the number of strokes taken at each hole. The objective is to have the highest score, unlike traditional scoring methods, where the aim is to have the lowest score. The Stableford system was developed by Frank Barney Gorton Stableford to discourage golfers from giving up on their round after just one or two bad holes.
Par values are assigned to holes, which include a regulation number of strokes to reach the green based on the average distance a proficient golfer hits the ball, and two putts. Holes are generally assigned par values between three and five. A score of one stroke more than par (+1) for a hole is known as a bogey.
Bogey competitions are also called handicap competitions or stablefords. In bogey competitions, golfers measure themselves against the bogey score.

SI is used to assign Stableford points
SI, or stroke index, is a numbering system used in golf to indicate the relative difficulty of each hole compared to the others on the course. Each hole is assigned a unique SI number, from 1 to 18 on an 18-hole course, with SI 1 denoting the most challenging hole and SI 18 representing the least challenging. While it is a common misconception that the stroke index is a ranking of holes by difficulty, it is actually primarily used for golf match play.
The stroke index is also used to determine how many shots one player must give to another in a handicap match. For instance, if one player has a handicap eight shots higher than their opponent, they will receive a handicap stroke on the holes with stroke indexes 1 to 8. This helps to ensure fair competition among players of varying skill levels.
In addition to Stableford competitions, stroke indexes are used in par and bogey competitions. In these formats, the need for a uniform and balanced distribution of strokes is less important, and the stroke index can be aligned with the ranking of holes by playing difficulty. This allows for both matchplay and strokeplay to be taken into account in the allocation of strokes.
