Chess.com Opponent Risk Score

Calculate risk scores for Chess.com opponents This extension helps you avoid playing cheaters (or those who seem suspicious). Right when the game starts, the extension pops up and shows you a risk score - the probability of your opponent being a cheater from 0 to 100, where 100 means that they're (almost) certainly a cheater. If the score is high or critical, you might want to abort the game before you start playing. The calculation is based on a primitive scoring model which considers 4 factors: - Overall win rate for each format - Recent win rate for each format (15-45 days) - % of High Accuracy games played recently* - Account age** These factors are combined, checked and weighted against each other, which results in the final risk score. On the options page, you can choose: - If you the risk score calculated based on all or only rated games - If you want to disable auto-pop-up behaviour. Note that this is recommended if you're running Chrome Version 126 or older. Please note that chess.com is not the fastest website out there. So sometimes the extension needs 5-10 seconds to load all the info. Just be patient! The extension source code, as well as the risk model description is available here: https://github.com/tim-sha256/chess.com-anti-cheat * High accuracy is considered 80%+ for rating in [0; 1500], and 90%+ for 1500+. ** Accounts younger than 60 days are considered more risky, and the overall score for them is multiplied by 1,5.
