Kasparov

no, you don't understand, he said,
there's a certain feel to a game,
a certain intelligence
I thought could only be human
how have they done this?

He lost the match in game two
when he resigned a game
he could have won,
assumed Deep Blue would make no mistakes.

We learned later
its next move would have been a mistake.

He was thrown into self doubt
when the machine suddenly looked human,
as though a thinking entity.
