Name of the Grandmaster
On your page
Did you know...? entry #57, you have posted the following: "A Computer Program named Deep Thought beat an International Grand Master for the first time in November 1988 in Long Beach, California".
Do you know by any chance who that GM was?
The first Grandmaster to be defeated by a computer was Bent Larsen, a Danish Chess player born on March 4, 1935.
On 1988, he lost a game to Deep Thought Computer in the Software Toolworks Tournament held in Long Beach, CA. He had the highest ELO rating of 2560.
He is considered the strongest Chess player ever born in Denmark and is credited with beating Bobby Fischer twice with black pieces.
