ManuTOO,
I wasn't sure where to post this -- Online Games, TE - Bug Report, or here --, as it really applies to the game as a whole but is maybe a bug that is primarily used in online games.
Some players are purposefully moving into a strike position such that visually the ball strike is with the handle of the racket. This results in a very dead shot that pretty much just clears the net and hardly rises after the bounce. Also, it doesn't have much displacement from where it bounces first to where it bounces the second time (assuming it isn't returned). In my last match where someone used this, the strategy seemed to be to serve well and then to use this shot, since the returner probably was a bit back to return the ball; it is hard to get to this ball after a return, as it is so short and deceptive (not like a drop shot as it appears to be coming toward you).
You can see the use of this shot in the attached recording. My opponent served well the first game but used this shot pretty much every time after the serve . After the first game, which he won, I won the second game quickly. Then, in his second service game, he used this shot again on both of his strikes of the first point of this game. You can see how he moved so close to the ball to create this effect. After he won that point, I decided to try to put an end to this and completely changed my game . When you watch the replay, you can see that this was no accident -- hitting with the racket handle. After I changed my tactic, he started trying other shots, and on many of those strikes you can see that he moved precisely into the correct position (green-corner) and was even able to do this with running rallies -- no more being too close to the ball. His serve was also pretty good. My point is that this racket-handle strike was intentional.
I'm not opposed to there being shot effects such as this in the game, but I think that they should have to be hit properly. It seems like a bug in the game that would result in such an effective shot when the player is far too close to the ball and hits the ball with the racket handle. In real tennis, I don't think that this would produce this type of shot or a winner so often. What do you think?
