The ultimate 6th game of Deep Blue 🆚 Garry Kasparov rematch in 1997 was played on May 11.
The score was even before this game, and it took the Machine 19 moves in the Caro-Kann to mark the revolution in chess making engines officially stronger than human.
Kasparov won 1, drew 3, and lost 2.

"The great mobility of the King forms one of the chief characteristics of all endgame strategy. In the middlegame the King is a mere 'super', in the endgame, on the other hand - one of the 'principals'."
