IBM Deep Blue Chess computer 1997

To put it mildly, chess has the reputation that winning in the game requires deep thinking.

It is true that a computer has beaten the best human chess player.

Deep Blue was a chess-playing computer developed by IBM. On May 11, 1997, the machine won a six-game match by two wins to one with three draws against world champion Garry Kasparov. Kasparov accused IBM of cheating and demanded a rematch, but IBM refused and dismantled Deep Blue. Kasparov had beaten a previous version of Deep Blue in 1996.

Was there cheating or not is not the point here.

It was NOT a smart machine beating a human as in some futuristic sci-fi movie.

It was a team of humans beating the human Garry Kasparov with the help of a electronic calculator they had constructed filling it with rules and logical patterns created in their brains.

In a way, it is like beating a sprinter in 100 meter run by using a motorcycle.
