Google's AI becomes world's best chess player in just four hours

An artificial intelligence program has become the world's best chess player in just a few hours - and it did it with almost no intervention from humans. AlphaGo Zero, developed by Google subsidiary DeepMind, is a descendant of AlphaGo - the AI program that conquered the human champion of the Chinese board game Go in 2016. After four hours of training, it took on the current world champion chess-playing program, Stockfish 8. Out of 100 games, it won 28 and drew the remaining 72. Even more impressively, it achieved this feat almost completely autonomously. The AI was given a few basic rules, such as how the different chess pieces move, but was programmed with no other strategies or tactics.
