I was downloading a database of his chess games and decided to read his Wikipedia entry to see what he’s been up to. This was a bit of a shock.
Viktor Lvovich Korchnoi (23 March 1931 – 6 June 2016) was a chess grandmaster and writer. He is considered one of the strongest players never to have become World Chess Champion.
Any chess fans can download a database of 1155 of his games here.
