If you have to use a program to play chess then you are missing the point of chess. Chess is the ability to solve complex problems and while computer use brute force to win a human used even more complex brain functions and many times can't even explain why a move was made when a better appearing move was ignored but yet they still won.
Chess is for your brain not theirs. IF someone is cheating it's not you that's actually being cheated. It's them.
Who is that person?
