I was just saying that you sometimes need to run at angles, so you can be in the best position to cover all possible passing lanes.
BTW: Do you ever try to run forward after your serve, but you run the wrong way?
For example:
You serve wide in the deuce court, but when you run forward, you run towards the ad court.
I'm never sure if I accidentally press the wrong way, or if it's a glitch. The worst part is that when I run the wrong way, I seem to run much faster.
I have trouble when approaching crosscourt sometimes too, because I just run straight forward. I think on TS3 that was better, because your player seemed to follow the path of the ball.
