Types of tennis match
An informal and unsanctioned form of tennis, this is played with similar rules to Canadian doubles, only in this version, players rotate court position after each game. As such, each player plays doubles and singles over the course of a match, with the singles player always serving. Scoring styles vary, but one popular method is to assign a value of 2 points to each game, with the server taking both points if he or she holds serve, and the doubles team each taking one if they break. Throughout the United Kingdom (particularly England) and Australia this format is usually known as "American doubles", whereas in South Africa you would call it "American singles", or cut-throat tennis. It is also found in the Caribbean
