In singles, the server starts in the right service court and serves into the opposite right service court. If the server wins a rally, one point is scored. The next service is from the left court to the opposite left court. This alternating process goes on so long as the server is winning points. Only the server can win points: should he or she lose a rally, the other player does not win a point but instead wins the right to serve. As in tennis, points are won when a player cannot return the shuttlecock or hits it out of the court. In men's badminton 15 points wins the game provided the score of the winner exceeds that of the loser by at least two points. If the score reaches 14-all, the player who first reached that figure can nominate to play on to 15 or 17 points. In women's play, 11 points wins a game and if the scores are level at 10 each, then there is an option to play on to 13 points. Women's doubles matches play to 15 points. The sport abounds in positional play and subtle manoeuvres, especially in the doubles game, where long rallies are commonplace. There is a wide variety of strokeplay ranging in power from delicate drop shots up to fierce overhead smashes, and the players need quick reflexes as well as a sharp turn of speed.
