The timer starts and the player looks at the screen. The first move is made and the game is on. The computer examines the position and makes its move.
Humans have been playing chess since the 6th century concocting different theories and positions. The knowledge of chess by humans is immense.
Computers can calculate many different variations of various positions. They can think almost twice as fast as a human.
In 1997, a grandmaster named Garry Kasparov versed a chess computer named Deep Blue and was defeated after six rounds.
Chess computers have a position database that contains every single chess position that is theoretically possible, making them far more superior to humans when it comes to the planning stage.
They are smarter and faster than humans are and therefore are able to defeat humans in a game.
As seen in the Deep Blue versus Kasparov games, it is clear that computers are indeed much better at playing chess than humans are.
