The games are surprisingly "human," filled with genius sacrifices. This AlphaZero AI is a Google creation made possible by the company's acquisition of a machine learning company called DeepMind. The programmers of AlphaZero did not "teach" the game to the computer in the traditional sense. That means no opening book, no endgame tables, and apparently no complicated algorithms dissecting minute differences between center pawns and side pawns. The AlphaZero was just taught the rules and pieces and in four hours of "learning" it was able to destroy the best chess engine, Stockfish. Humans better watch out...AI is coming!
