In Focus-Weekend | Something Strange on the Chessboard? Call the Chess Detective.

In India’s coastal state of Goa, the world’s best chess players are chasing titles at the FIDE World Cup, a biennial tournament run by FIDE, the International Chess Federation. On the East Coast of the United States, Kenneth Regan chases fairness. Each night he downloads every game, feeding the moves into his program to see if the play looks human or too perfect. Cheating today isn’t just glances or notes. It can mean phones, signals, or online help from chess engines. Regan’s math hunts for patterns that feel off, walking the thin line between genius and help. From the 2006 “Toiletgate” scandal—when a world champion was accused of using computer aid during long bathroom breaks—to the 2022 storm between Magnus Carlsen and Hans Niemann, when Carlsen withdrew mid-tournament, suspicion has shadowed the board. Regan’s work keeps the focus on the moves, not the murmurs.Guest: Kenneth Regan, Professor of Computer Science, University at Buffalo; Anti-Cheating Expert for FIDE, the World Chess Federation Host: Anupama Chandrasekaran Edited by Jude Weston Learn more about your ad choices.
