People using programs to cheat usually don't tell on themselves, so maybe there is another reason he told you he using a program. Anyone using a program learns little about playing, but for some people winning is more important than anything else. I've played chess with people I know were using programs for making moves. They aren't weren't smarter after playing with programs than they were before they started, so as far as I am concerned I'm not the one who loses something.

Why would he tell you he was cheating if he was really cheating?
