Tribute to Jim Warren: Elo Expert

Chess expert Jim Warren outplayed Bobby Fischer twice in the Sicilian Defence.
This same James E. Warren developed the computer program for Elo chess ratings.

On Friday, December 12, 2014, Tim Just posted the following:
"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."

When professor Arpad Elo produced the FIDE Rating List in 1969 he wrote:
"Grateful acknowledgement is made to Mr. James Warren of Western Springs, Illinois, who wrote the computer program for the method of successive approximations and performed the computation for the 200 selected players."
Arpad E. Elo, Member, FIDE Qualification Committee, USCF Ratings Chairman

Jim Brotsos, Co-founder of the Chicago Industrial Chess League wrote in part:
"Jim Warren has already received mention as one of the pillars of the League. In addition, he has had leadership roles in the Illinois Chess Association and the APCT. In 1997 he received the U.S.C.F. Meritorious Service Award for helping to establish the FIDE rating system. He and his wife have sponsored major regional tournaments and the U.S. Masters, often acting as financial patrons... They are, no doubt, the most influential couple in the history of Midwestern American chess. Jim has a significant collection of chessmen and one of the largest collections of chess books/magazines in the Midwest."

Robert James Fischer was born March 9, 1943 in Chicago, Illinois, but Fischer grew up in New York. He returned to Chicago on March 23, 1964 for his simultaneous exhibition tour and scored +49 =4 -1. Just two months later in another simul Bobby Fischer scored +44 =5 -1 in Cicero, Illinois on May 20, 1964. In both, Bobby Fischer played the same first 18 moves vs Jim Warren in the sharp 6.Bc4 Sozin line of the Sicilian Defence. Jim Warren won a pawn in each game. Fischer had to fight hard to draw. In early 2015, I hope to post my own games vs Jim Warren.
