Change of ends

I have already asked this question before, but i can't find the answer to this question on pingskills.

The question was why players change sides in some matches? I don't have the link of the video I saw.

Hi Sourav,

Here is the link to the previous question.  I did a search on the Ask the Coach page for your name and Changing Ends and it gave me the question I was looking for.

Try this link. Change of ends.
