Chess Mom is the second part of the sixth aired and seventh produced episode in season 4 of Dexter's Laboratory, which aired on May 23, 2003. In this episode, Mom poses as a personal cheerleader to Dexter as he is playing at a chess championship. However, Mom's cheering only leads to Dexter's embarrassment, as one is to be quiet during a chess competition.


Dexter's mother attempts to support him during a chess tournament but does nothing but embarrass him.


Dexter is playing chess at the big championship and his Mom is watching. Unfortunately, she doesn't realize that the audience is to be completely silent during the chess tournament (so the players can concentrate) and cheers for Dexter really loudly. This leads to Dexter's mother being told to leave by the announcer and for Dexter to lose the competition. Dexter becomes depressed that he didn't win, but his mother beats up the winner's obnoxious father and claims the trophy for Dexter, prompting Dexter to hug her and say she is the best.
