A completely fair playing field will not give any advantage to commercial programs 2. If commercial programs are just a little bit better, a contest of (perhaps) 20 games could easily lean in favor of the weaker programs. 3. If amateur programs are actually as strong as the commercial ones (or even nearly so) it will make the commercial programs look bad. Perhaps I am seeing controversy where there is none. Perhaps I am imagining subversion where nothing of the sort exists. But then again, they have been aware of the exact nature of the problem for many, many years. A fixed version appears, and right away it is broken again. Purely coincidence, I imagine.
