Possibly there is a flaw in your thinking, and philosophy, that is going to prevent you from playing successful all court tennis.
If your opponent hits a screeming meemie low and at your feet, you do NOT need to reply with a hard hit fast winner. In fact, percentages are in your favor if you just shovel it back deep, move another 2 steps forwards, and get ready to put the next ball away.
WHY? you ask. Consider the other way around. YOUR opponent comes to net, you blast a 85mph screeming topspin at his feet, WHAT ARE YOU THINKING? I'll tell, you. You are thinking you have won the point. If the opponent tries to reply with a screaming winner, YOU WILL HAVE WON THE POINT.
IF, OTOH, your opponent just half/low volleys it back deep to your court, what is your mindset? NOW, you are confused, mad, your winner didn't work, and you're going to BLAST the next shot even harder!
Right?
So, just shovel it back deep, move forwards 2 steps, anticipate getting a faster passing shot, but keep the lob in mind, and allow him to hit his clean winner IF HE CAN.
IF HE CAN, he is beyond your skill level.
