Meaning
Conditions Affecting the Stroke are five protected elements relevant to the next stroke: the ball's Lie, intended Stance area, intended swing area, Line of Play and any Relief Area used to drop or place a ball. The Rules restrict deliberate improvements to these conditions.
How it matters in match play
The definition is the same in match play as in other forms of play, but a breach can change the hole result. Before a stroke, a player must normally accept these conditions and must not improve them except where the Rules allow. A player may ask for a Ruling if an opponent alters a protected condition or takes relief incorrectly.

Worked example
Illustrative example: Alex's ball lies beside a branch that interferes with the intended swing; Alex may not break the branch to improve the Conditions Affecting the Stroke, so the hole continues with the original lie unless another Rule provides relief.

Common questions
What are the five Conditions Affecting the Stroke?
They are the ball's lie, the area of intended stance, the area of intended swing, the line of play and the relief area where a ball will be dropped or placed.
Can I remove a loose impediment if it improves the conditions?
Usually, yes. Rule 8.1b permits reasonable actions such as removing loose impediments and movable obstructions, even when that improves a protected condition, subject to the specific Rules governing those actions.
Does this definition apply in match play?
Yes. The definition and Rule 8 restrictions apply in match play. A breach may affect the hole under the applicable Rule, so players should resolve uncertainty through the match's authorised ruling procedure rather than invent a local outcome.
Is a player entitled to free relief whenever a condition affects the stroke?
No. The definition identifies protected conditions; it does not itself grant relief. Free relief depends on a separate Rule, such as Rule 16 for interference by an abnormal course condition, and on that Rule's requirements.
Can a player restore a condition that was worsened by someone else?
In limited circumstances, yes. Rule 8.1d allows restoration when conditions are worsened by a person other than the player or by an animal, or permits a comparable replacement procedure when restoration is not easy.
Does the line of play include the air above the ground?
Yes. The defined line of play includes the intended direction after the stroke and a reasonable distance above and on either side of that line.
