Christina Tao shared a link from chess.com which concerned me and reassured me.

We believe there are two key points to take away from these numbers:

  1. Cheating is very common on a day-to-day basis.
  2. Chess.com is taking action against it!


Chess.com regularly receives complaints about members who have an excellent accuracy score in a game. We are thrilled to see our members using game reports, but the accuracy scores that are provided are not a part of our cheat detection, and they shouldn't be considered immediately damning evidence of cheating. Even beginning players can achieve very high accuracy scores if their opponent errs early, and they capitalize on the clear mistakes.
