this question is more interesting than it seems at first!
a famous european coach just said this

If you see how American kids play, I think the forehands and backhands and serves are as good as the players in the rest of the world, but in general they don't play as well in matches. When I watch juniors play matches they often seem “disconnected” from one shot to the next. I think this is because we don't emphasize point play enough. We don’t emphasize the reasons you should hit the ball to certain places at certain times, or where your court position should be. The way I see it American kids are more used to hitting balls than really playing matches.

in europe, beginners are taught to think about strategy etc SOONER than in the USA. part of this is a function of surface, of course.
i think the original poster is asking a very smart question IF HE WANTS TO WIN MATCHES, rather than just ask IS THIS AN NTRP 4.0 BACkHAND?
lets start thinking about winning more matches, and give the stroke envy a rest. someone wrote recently that if you watch the strokes of a 100 ranked player and a 10 ranked player, it is very difficult to tell who is who.
almost forgot - to the original poster, get brad gilberts book, Winning Ugly. it is the best answer to your question that you are likely to get anywhere.
and just to clarify, i am not suggesting that strokes and technique at a beginning level are unimportant. i am just saying that a beginner who says that he is already working on stroke production and now wants to learn some strategy...that is a very wise beginner! its is a wiser question than the usual HOW CAN I HIT THE BALL HARDER DUH? WHAT STRINGS GIVE MORE SPIN DUH?
at your level, do not miss, do not make unforced errors (this goes back to what someone said above, about sending the ball back to where it just came from, the easiest hit you can make). do not think in one-shot time frames, but rather use a shot to move your opponent to where you want him, so you can hit to where he is not. do not be impatient, be ready to hit as many balls as it takes to win the point, do not get impatient and start trying to hit through your opponent to end the point early! hit some moonballs to your opponents backhand side, and see what they can do with that. keep that ball in play no matter what. hit up the middle and come to the net, and see what they can do with that. think, just dont mindlessly hit hard, think.
