I know there are a few board members who have called the lines at big tournaments - I've always enjoyed reading about their experiences from so close to the action. During the course of this Oz Open (and any tournament, naturally), there have been some dubious line calls. Obviously, you can't be 100% perfect all the time. What's it like, though, when you make a call that gets overruled? Are you more nervous calling that line for the rest of the time you're stationed there? Do you have to stop yourself from jumping the gun next time? Have you ever had a player try and intimidate you? (and if so, did it work?) I guess a lot of this comes down to individual personality as well, but I've always thought it seemed like a tough job and in the heat of the moment things could get really interesting down on court.
