What is the procedure in warning a player in table tennis?

Answer 1

Yellow and red cards are shown by umpires and referees to players and coaches who break the rules or misbehave during the course of a match or tournament.

For less serious offences the umpire may, on the first occasion, hold up a yellow card and warn the offender that any further offence is liable to incur penalties.

If the player then commits a second offence in the same individual match or team match, the umpire will award 1 point to the offender's opponent.

And for a third offence he will award 2 points, each time holding up a yellow and a red card together.

If a player continues to misbehave after three offences in the same individual match or team match, the umpire will suspend play and report it immediately to the referee.

If a coach continues to misbehave after receiving a yellow card, the umpire will hold up a red card and send the coach away from the playing area.
