Yes, I always play as fair as possible. There's no honor in winning through illegitmate means, even if it isn't me doing the call.
In all my matches I have had few disputes with other players. Even in high school, which was basically hook-city, I was able to level with most players and we could play a fair match. Sometimes other players thought I was cheating them, but to my knowledge I called every ball honestly. I might not have been RIGHT everytime, but I never deliberately fooled anyone either. I'm not all rightous and honorable or anything - it's just what I would like my opponent to do for me.
I have found most people do the same when they learn to trust you. It's a few bad seeds that make everybody untrusting and critical.
Rafter played fair, and I always looked up to him for it. Henman is good about that too.
