Trust & Fair Play

Every practice game is monitored. We record move telemetry, run post-game engine correlation on credit-funded games, and review flagged accounts by hand before any action is taken. Actions range from a warning to suspension of credit-funded practice to a permanent ban.

Bans with high severity appear on the public ban list when the player has opted into transparency. Players can always appeal a decision by replying to the notification email.

Credit-funded practice rewards the helper for playing a session to its natural conclusion, regardless of the result. Nobody on Chessco earns credits for winning; that framing is deliberate and enforced from copy through to the database schema.

The accuracy figures we publish on the benchmarks page come from scheduled runs against our own corpus, with the methodology stated next to each number. When a benchmark measures an easier variant of the real task, we say so.

We index publicly published federation rating lists and publicly available online games. Players can request delisting from search at any time; see the privacy policy for the process. Anonymous online accounts are never reverse-mapped to real names without public evidence linking them.

Questions, appeals, or delisting requests: support@chessco.org.
