changing courts

hi

I notice ma long and xu xin playing in the middle of the set, they just change courts. All I thought is that you can only change court after the setpoint. Is it Ok? How many times can you do it in a game?

Thank you,

Judah

Hi Judah,

In the deciding set so if it a best of 7 set match then in the 7th set the players change ends when the first player reaches 5 points.  This is to make sure that if there is an advantage at one end that both players have the same opportunity.
