> Expected strokes is the average number of strokes a benchmark golfer needs to finish a hole from a specific distance and lie, and it is the number strokes gained subtracts before and after every shot.

Expected strokes is the mechanism behind [strokes gained](https://pinflag.io/glossary/strokes-gained): every position on a hole, defined by a distance and a [lie](https://pinflag.io/glossary/lie), has an expected-strokes value, and a shot's strokes gained is simply the change in that value from before the shot to after it, minus the stroke just played. See [baseline](https://pinflag.io/glossary/baseline) for how that reference value is built.

The number moves sharply with both distance and lie. From 8 feet on the green, PinFlag's Broadie-verified baselines put expected strokes at 1.500; from 25 feet, it's 1.931. From 155 yards in the fairway, expected strokes is 2.960; from the same 155 yards in the rough, it rises to 3.210 — the extra strokes that lie typically costs.

Expected strokes lets a coach make like-for-like comparisons across very different starting points: a green hit from heavy rough and one hit from the fairway are not equally difficult positions, and expected strokes quantifies exactly how much harder one is than the other.
