Originally posted by greenpawn34Before I looked at the game, I had a good guess what the final position would be, and the big surprise for me was that I was close to right, except tha the picture was a mirror image of what I expected! Very cool post!
The very first human to lose to a computer in a tournament game
was one Benjamin Landry playing MacHack VI in the Mass Ch. 1967.
Here is the game. MacHack was White.
Note the final position and compare it with the end of a famous Morphy game.

And this is horror story that all computers talk to each other about.
The 2nd US Chess Computer Championship, Chicago 1971.
COKO 3 v Genie
This position arose with White to play.
The computer can mate in one move with 1.Qb2 or 1.Bc4.
However the computer had been given a numerical value for mate
and here it can mate in two ways both with the same value.
So it moves keeping the mate in one on waiting for either the
Bishop or the Queen to be captured so it can mate in one move.
White lost.
