The scoring method used in squash is called point-a-rally scoring, where a point is awarded on every serve regardless of which player serves. Matches are typically played to 11 points, with players requiring a margin of at least two points to win. This scoring system encourages continuous play and increases the game's competitiveness. Players must strategically place shots while anticipating their opponent's moves, making squash a fast-paced and dynamic sport that combines skill and endurance.
