=== Cheating and fair play ===
{{see also|Cheating in chess}}
Unlike traditional over-the-board tournaments where handheld metal detectors are employed in order to counter players attempts at using electronic assistance, fair-play monitoring in online chess is much more challenging.

In response to these issues, chess platforms such as [[Chess.com]] developed AI-based statistical models which track improbable moves by a player and compare them to moves that could be made by an engine. Expert examination is conducted for all suspected cases, and the findings are published on a regular basis. FIDE introduced AI behavior-tracking technology to strengthen [[anti-cheating|anti-cheating measures]] in online events.<ref name="Research"> Duca Iliescu DM.

==== Challenges in cheat detection ====
AI-based detection systems use a combination of machine learning to track suspicious player actions in different games. This is done by measuring discrepancies between the real moves and the predicted moves derived from the available statistics. Players of unusually high skill level or unusual strategies that can imitate moves characteristic of automated chess systems. Each case is examined by a human expert to ensure that the decision is correct before any actions are made to guarantee fairness and accuracy.<ref name="Research" />
