On occasion, I manage to play the best move in the position. Does that mean I'm cheating?
Chess.com's anti cheat service is a joke, I have the solution

No, what this does is watches if the opponent continuously makes the "perfect" move based on a compilation of games and ALSO an algorithm which recognizes "best moves" based on mathematical probablilies.. A human could NOT be able to consistently make those moves. Keep in mind, like ANY chess engine, even one as complex as Deep Blue, there are ways to defeat it. However, this is NOT a competing program. It simply alerts the user of the possibility their opponent is using a program,
I have developed a script, a database of several hundred thousand GM games from the last 50+ years that will "watch" your opponents moves and also use a simple algorithm that decides what the opponents best move should be (not unlike what any chess program does) and alerts you when he/she makes that particular move, therefore letting you know if they are cheating or not. My script does not tell you the moves before they are made so it cannot be used for cheating. IT SIMPLY INFORMS YOU IF YOUR OPPONENT IS. In a way it is like PunkBuster but for Chess! Feel free to contact me for more info.
(Chess.com admin: please consider using my script, I WILL SELL IT TO YOU FOR A VERY REASONABLE PRICE. It is free for individual members for a limited time)
