Players play a set where the server always starts at 30:40.

Variations:

• Play no-ad
• The server has only the second serve

Benefits:

• Players will inevitably win some of the games when they are 30:40 down and this will start building their confidence. When they experience this situation in the match they'll know that they can win from there. They won't panic or surrender before the point even starts.
• The returner will realize that it's not the best tactic to play passively. Unless of course he plays with a very scared opponent who chokes under pressure. But hopefully eventually the scared player will realize that this approach doesn’t lead anywhere (coach’s suggestion helps) and will change his game. That's when the returner will have to step up again.
