There's been an exchange of notes on the Team England site about cheating and how highly graded players get detected and their accounts closed. Perhaps there is a need for lateral thinking about the question of cheating. There could be events for players who are open and honest about using engines. Some chess fans want to compare the performances of the different softwares with each other and with what a human can do, and I don't see anything wrong with that as long it's done transparently. After all, use of opening books and games databases is allowed in turn-based chess, and I admit to making use of the Games Explorer. I'm unsure this is morally different from using an engine. It's not cheating but only because it's permitted.
I've got academic qualifications in philosophy so I'm good at moral reasoning. Shame about the chess.
