Lawrence C. "Larry" Kaufman (born 1947) is a chess Grandmaster, a title which he automatically earned after winning the 2008 World Senior Championship (which he later retroactively shared with Mihai Suba). He was an International Master before that.
A longtime researcher in computer chess, Kaufman has made several contributions to chess-related works. He helped write the opening book for the pioneering program Mac Hack, co-developed Socrates II and its commercial adaptation, Kasparov's Gambit, edited the journal Computer Chess Reports, and worked on many other research and commercial chess engines. He is also known for his work on computer chess engine Rybka 3, and several books and articles, including The Evaluation of Material Imbalances. He helped develop the chess program Komodo with Don Dailey, with whom he had worked on the Socrates series of programs. After Dailey's death in 2013, Kaufman resumed his work on Komodo with Mark Lefler.
Kaufman has reached a considerable level of competence in several other board games. He is one of the strongest shogi players in the west; he learned the game by the traditional method of studying handicap theory and is one of the leading experts in this field. Go and Xiangqi are among his other past interests.
Larry Kaufman's son, Raymond Kaufman, is an International Master.
