Worst grandmaster by rating https://www.chess.com/forum/view/fun-with-chess/worlds-lowest-rated-grandmaster
This is a joke thread about the 'world's worst grandmaster', Panko Smoobachuk. Seeing this post, I wondered, what is the world's lowest rated grandmaster?
The new, munged* FIDE rating website still has the old &quot;Advanced Search&quot; option, but the page doesn't have its own URL. There you can search for GMs from all countries sorted by rating ascending and then you get that the Russian GM, Vasily B Malinin, born in 1956 is the lowest rated GM with a standard rating of 2100.
Looking at his individual calculations shows that his rating has been in steady decline since 2004 which would suggest some life-changing event happened then, perhaps a health problem, which affected his chess playing ability.
