Kim Commons passed away last Tuesday (June 23) at the age of 63 after suffering a stroke the previous weekend. Commons was an IM who had given up serious play decades earlier, but was an up-and-comer in U.S. chess in the '70s. (Have a look here for a sample of his play during those peak years.)
I knew of him and think I had seen his name on some chess servers, but never met him in person or played him online, as far as I know. Perhaps Ken Regan or another player who was around during Commons' career would like to offer some memorial comments?
In any case, my condolences to his family and friends; may he rest in peace.
