Helen Warren informed me this AM that her husband Jim Warren died. His heart gave out. I have few details. The death notice and funeral details will be in the Chicago Tribune a week from Saturday, according to Helen.
Jim worked with Elo in developing the ratings formula. Along with Helen he ran APCT for years. They sponsored many Master chess events over the years, including the U.S. Masters.
There was a profile written 35 years ago. Interestingly enough, he said the programming he did for the CICL ratings (Chicago Industrial Chess League) was a fore-runner of the work he did for the FIDE/ELO ratings.
{The main line is the game Jim Warren played against Fischer at the Edgewater
Beach Hotel in March 1964; their Cicero game from May 1964 is cited in the
notes to White’s 19th move. I’ve referenced a couple other famous Fischer
games to give the reader an idea of how impressive it was to get Bobby into
trouble in this line, even in a simul.} 1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4
