I have been playing for a number of years and as a consequence have had a few different coaches. My standard is probably around the high end of intermediate, maybe better.... I'm county level(UK).Recently my coach at club and county have been saying different things. One of them says that i need to work on a backhand clear because I always go round my head and leave too much space open on the other side of the court. My other coach says just work on your movement and never to turn my back on my opponent in singles........ I'm not sure what I should be working on. Which do you use?
