- Author created a Chrome extension to detect potential cheaters on chess.com by analyzing opponent stats.
- Cheating is widespread, especially at higher ratings (2200 rapid, 1900 blitz), with 3/5 rapid opponents suspected.
- Extension computes a risk score (0-100) based on winrate, account age, and high-accuracy game percentage.
- Chess.com's anti-cheating measures are ineffective; few reports lead to bans, and abort limits hinder fair play.
- The model uses a weighted mathematical formula, with configurable thresholds; code is open source on GitHub.
- Future updates may include scoring history, report tracking, and abort limit warnings.
