Answer for Watch the ball or opponent

Hi Starsky,
Thanks for your question.
Yes I would say after you have made contact with the ball you want to now keep an eye on your opponent. Look at their body positioning and alignment. You will then be able to read the play a lot easier and quicker keeping an eye on your opponent. Watch the opponents bat angle so you can judge how much spin they will produce, also it can give you a good indication on where they will pace the ball. When you have played your shot also get ready and in position for the next shot. Be on the balls of your feet and return to the recovery position. You need to recover relative to the line of play: https://tabletennisdailyacademy.com/videos/stance-ready-position/ we look at open points in the video there.
Hope this helps
