Can Artificial Intelligence identify your style of play?
AI Unmasks Anonymous Chess Players, Posing Privacy Risks
Software that identifies unique playing styles could lead to better tutorials and games

Think your bishop’s opening, queen’s gambit and pawn game are unique? A new artificial intelligence (AI) algorithm has ingrained your chess style. AI software can already identify people by their voice or handwriting. Now an AI has shown it can label people based on their chess-playing behavior, a breakthrough in ‘stylometry’ that could help computers be better or more human chess teachers in their game. Alarmingly, the system could also be used to help identify and track people who believe their online behavior is anonymous.
“Threats to privacy are growing rapidly,” says Alexandra Wood, an attorney at Harvard University’s Berkman Klein Center for Internet & Society. She says studies like this, when done responsibly, are helpful because they “shed light on an important mode of loss of privacy.”
Chess software, such as Deep Blue and AlphaZero, has long been superhuman. But Ashton Anderson, a computer scientist at the University of Toronto and principal investigator of the new project, says the chess engines play an almost “alien style” that isn’t very informative for those looking to learn or improve their skills. . They better tailor their advice to individual players. But first, they had to capture a player’s unique form.
