I've said it before and ill say it again:
The best response to cheating is not to cheat back. I think the whole concept of "im going to call his next ball out no matter what" is just childish and disingenuous.
You can get back at them in a lot of ways without blatantly cheating.
It's easy to beat a "powder keg". All you have to do is light the fuse and step back. Keep your cool. They'll explode on their own.
Very few players actually get better when they get angry. Very few.
Most of the time people lose to cheaters because they dont know how to respond. They either cheat back causing a mutual explosion or curl up into a ball and lay in the corner of the court. Their excuse: "The other guy cheated."
