Re: Lichess question

https://database.lichess.org/ I downloaded several 2019 PGN's. They contain about 30 million games each. When I make a selection on elo=2200+ (both players) the output is below 1%. Makes me wonder, either there are not many strong players or they maintain a non-standard elo rating. Ratings are not ...

Cock suffered from brain cancer. Radiation and chemo in the end did not help. At his 70e birthday he gave a party for his closest friends to (as he said) celebrate his life. As he told me, never lose your sense of humor.

RIP

Condolences to Trudy his lovely wife.
