Service and return.

One of the most important things in the game is SERVICE. The server first stands with the ball held on the open palm of the hand not carrying the racket, called the freehand, and tosses the ball directly upward without spin, at least 16 centimeters high. First the ball touches your court and jumps to the other court. If the ball hits the net and still fell to the other court, it is new service. But if the ball touches the net and doesnt go to the other court it is point for the other player.The ball must remain behind the endline and above the upper surface of the table, known as the playing surface, at all times during the service. The server cannot use his body or clothing to obstruct sight of the ball; the opponent and the umpire must have a clear view of the ball at all times. If the umpire is doubtful of the legality of a service they may first interrupt play and give a warning to the server. If the serve is a clear failure or is doubted again by the umpire after the warning, receiver scores a point. you can hide the ball with your hand(not actually touching it) and do a surprise service. Then you have more time to prepare for the return. If he is surprised and he returnes the ball you can hit the ball with the racket for a long hit. Then he could miss.http://en.wikipedia.org/wiki/Table_tennis#Starting_a_game
