Here are some quotes on strategy from people I respect. These “rang true” for my many players in many matches.
Find out what your opponent can’t do, or doesn’t like to do, and make them do that.” Jack Kramer
(Think Nadal over Federer in 2007 French Open. Target? Federer’s backhand.)
Don’t change the “line of the ball” unless you are sure you can make the shot. Otherwise cross-courts “ad nausea.” Two-handed back- hands down the line shots will “slide wide” too often, believe me. T. Parham
When asked what he would do differently, Ken Rosewall replied, “..I would hit a lot more balls cross court.”
Cross-courts get you out of trouble. Jim Verdieck demanded the cross court ball from his team.
Get yourself in a position to “volley away from the source” Verdieck
Any ball hit extremely deep in either corner allows a good attacking possibility Verdieck (“2 and in”)
The simple strategy of tennis singles: “Attack the short ball” Dennis Van Der Mear
Good approach shots make easy volleys J. Leighton
No shots in “no man’s land” is a myth T. Parham
Rule 1 – Find a good doubles partner
Rule 2 – Get along with him/her
