In May 1997 a different kind of Chess game began, which draw the attention of the whole world. It was a game between a man and a machine. The man was none other than the world champion chess player Garry Kasparov, and the machine was IBM’s supercomputer Deep Blue. After several days and six matches, Deep Blue beat the world champion on 11 May, 1997 – two wins for Deep, one win for Garry Kaparov and three draws. Yesterday, IBM celebrated the 15 anniversary of Deep Blue’s historic victory.
