ITST rules

[Andamce Williams]

In ITST, u can put your player inside while the ball is coming? For example, you put your player behind the line (like in real tennis) but when the ball comes your player automatically enters slighty to the court (like in real tennis i think), because to return low services i think its normal to get inside in real tennis. You can do that in itst?

For example, like this return of federer: http://www.youtube.com/watch?v=Uwg08G60-68
he's behind the line but when murray executes her service he enters to the court.
