AI’s Hidden Vulnerabilities in the Games of Chess and Go: How Human Players Can Outsmart the Machines
Go and chess have long been touchstones in the world of artificial intelligence due to their intricate strategies and vast number of possible moves. Among the myriad AI programs tackling these ancient board games, KataGo and AlphaZero stand out as some of the most formidable, capable of easily defeating the world’s top human players. However, the narrative took an intriguing turn in recent years when researchers uncovered that these AI could be outmaneuvered through adversarial attacks.
The Power and Perils of AI in Chess and Go
KataGo and AlphaZero have earned their reputations through rigorous training and advanced algorithms. They play at levels that far surpass human capability. These AI marvels process thousands of potential moves in seconds, predicting and countering human strategies with uncanny precision. Yet, despite their prowess, they aren’t invincible.
Adversarial Attacks: The Achilles’ Heel
In surprising twists, researchers demonstrated that even the mightiest AI can have weaknesses. These weaknesses were exposed through adversarial attacks. Hostile bots identified and exploited vulnerabilities within the algorithms of KataGo and AlphaZero. By employing unconventional moves and strategies, these bots managed to outwit the AI. They created blueprints that human players could use to their advantage.
How Adversarial Attacks Work
Adversarial attacks involve feeding the AI deceptive inputs, leading it to make errors. In the context of Go, this meant identifying moves that, while appearing suboptimal, could confuse KataGo. These moves forced it into less advantageous positions. In chess, similar tactics involved non-standard opening strategies or unexpected middle-game moves that led AlphaZero into suboptimal play. Often overlooked by standard play, these moves became powerful tools in the hands of informed human players.

Human Players and the New Strategy
With these new strategies in hand, human players found themselves equipped to challenge KataGo and AlphaZero more effectively. By mimicking the unconventional moves used by the hostile bots, they could navigate the game in ways that the AI had not fully anticipated. This development highlighted a fascinating aspect of AI: while it excels in traditional, logical play, it can be tripped up by unpredictability and creative thinking.
The Future of AI in Go and Chess
The implications of these findings extend beyond Go and chess. They reveal a critical aspect of AI development: the necessity for continuous improvement and adaptation. As AIs become more advanced, so too do the methods for testing their limits. This dynamic ensures that both AI developers and users remain vigilant and innovative.
The Evolution of KataGo and AlphaZero
KataGo and AlphaZero’s journeys began as attempts to push the boundaries of what AI could achieve in the realm of board games. Through deep learning and extensive training on vast datasets of Go and chess games, these AIs developed abilities to predict and counter a wide array of strategies. Their successes underscored the power of machine learning and the potential for AI to excel in tasks requiring strategic thinking.

AI Cracks the Code of Chess Brilliance
Researchers at the University of Toronto have developed an innovative AI model that can understand how humans perceive creativity in chess. Unlike traditional chess engines that focus solely on maximizing win rates, this new model is designed to recognize and replicate “brilliant” moves—those that may not immediately appear advantageous but demonstrate deep strategic insight.
The researchers, using techniques like game trees and deep neural networks, trained their model on data from the Lichess database, achieving a 79% accuracy rate in identifying brilliant moves. This work, which was presented at the International Conference on Computational Creativity, could lead to more creative AI systems in other fields, such as music and art.
The team collaborated with advanced chess engines, including Leela Chess Zero and Maia, to develop this model. The project, based on an undergraduate thesis, has received significant attention, with experts suggesting it could serve as a valuable training tool for chess players and enhance the entertainment value of AI opponents.
Ultimately, the researchers aim to apply their findings to broader creative domains and are considering making their “brilliant” chess engine available for public play.
Learning from Adversaries
The discovery of adversarial attacks on KataGo and AlphaZero was not just a setback but a learning opportunity. Researchers delved into the mechanisms of these attacks, identifying the specific ways in which these AIs’ decision-making processes could be misled. This research has broader implications for AI safety and robustness. Understanding how AIs can be manipulated is crucial for developing more resilient systems.
Practical Applications Beyond Board Games
The techniques used to uncover vulnerabilities in KataGo and AlphaZero have applications beyond the realm of board games. In cybersecurity, for example, similar methods can identify and patch vulnerabilities in software systems. This cross-disciplinary knowledge transfer highlights the interconnected nature of AI research and its practical benefits.
Ethical Considerations
The ability to manipulate AI systems raises important ethical questions. How should such knowledge be used, and what safeguards should be in place to prevent misuse? These considerations are crucial as AI continues to be integrated into more aspects of society. Ensuring that AI systems are not only effective but also secure and ethical is a growing focus within the field.
