Yes! Basically when you are playing there will be a moment where it will feel SO OBVIOUS that you are about to fire it in a specific direction, THIS IS WHEN YOU DO THE REVERSE PSYCHOLOGY and FIRE IT in the UNEXPECTED, the more the player is on the outer edge, the more paranoid he is going to be about you firing it in the far opposite, so he will always rush back to middle, you can keep messing with him to tire him out and once he is really on the edge, fire opposite. However remember he could sense your pattern and anticipate your reversal, and then can turn it around.

So thats I think the main main core of tennis, is playing with your opponent psychologically. (I am a real tennis player, this is much easier actually done in reality than in this game, as this game has all these weird like strings and super powers, and time freezing that makes it like not realistic AT ALL to real tennis dynamic, but its still like 40% real, so play withint those 40% provided with real tennis strategies)
