In the figure of a Turk with a large box stood a strong player and won all the opponents, i.e. people who admired this "miracle" and that strong player would be hidden in the box while they opened the Turk, while the box was opened, this strong player hid in Turk.
Today there are chess computers that have artificial intelligence and can win the strongest players like Magnus Carlsen and the team at the top.
The computer can also be instructive because it contains something called "chessdatabase". There is a database of opening, games, endgames and analysis.
