I have tried to understand why some players would use a computer to make their moves. I can think of at least three cases, two of which are confirmed, in which players were using computer programs to beat me. I think that some of these players try to win by themselves at first. After realizing that other players are better their ego suffers badly and psychologically they give up on winning on their own. They start using a program and they get some satisfaction in seeing other players struggle while all they do is feed moves into a program. Their ego breaks down, so they lose perspective of what fair play is. I know my ratings are quite low, but they are my ratings, not Chessmaster 9000, or Gothic vortex, or some other program's ratings. Computer programs have a place. You can use them to practice at home, or to analyze positions after a game is completed, but using the program to defeat an opponent in the middle of a game is cheating.
