Nothing wrong with your strategy.My original question was "What is your main singles strategy"?
My answer in it's most basic form is: I prioritize depth of shot above all else.
I can anticipate your response. "Do you mean you try to hit the back fence or even over the fence"? Yes, that's what I try to do and what I mean by depth.
But you're crazy if you anticipate that kind of response from me.
In fact, my first response to you was about having sufficient power, to which you said "right".
