It sounds more like something that would happen during a high school exam, but as The New York Times reports, the world of elite chess has been fraught with fraud in recent years. Players have been accused of collusion for using coded text messages and signaling systems to relay game moves, and in one particularly scandalous case in 2006 — dubbed "Toiletgate" — player Vladimir Kramnik was accused of collaborating with a computer in a nearby bathroom. But professor Kenneth Regan from the University of Buffalo is working on a program to detect the devious work of chess cheaters. To do so, he set out to create a model of how often player moves match those of chess programs by building and analyzing a database of games dating back to the early 19th century — to date, he's analyzed nearly 200,000 games. Be sure to catch the full NYT article for full details on Regan's methods.
