2. During exciting games, try to control yourself. Don't criticize the performance of players and coaches. Be careful with your words, since some may cause anger among other people in the audience.

3. Applause is a special form of body language you can use to communicate with players. But you should do it properly. When players first appear, clap your hands together to welcome them, but don't go on for too long. After an excellent performance, applaud warmly. If someone fails, your applause will help encourage them. Applause is not welcome, however, while a game is in progress and players need to keep their concentration. Various sports have various rules for the audience.

4. Snooker and table tennis courtside behaviour includes a ban on flash photography.
