[edit] Career
John Nunn went up to Oriel College, Oxford, to study mathematics when he was only 15 years of age in 1970. At the time, it was said that he was Oxford's youngest undergraduate since Cardinal Wolsey. He graduated in 1973, gained his doctorate in 1978 with a thesis on finite H-spaces, and remained at Oxford University as a mathematics lecturer until 1981, when he became a professional chess player.
In 1975 he became European youth chess champion. He gained the Grandmaster title in 1978 and was British champion in 1979. Nunn has twice won individual gold medals at Chess Olympiads. In 1989 he finished sixth in the inaugural (and only) World Cup, a series of tournaments in which the top 25 players in the world competed. His best performance in the World Chess Championship came in 1987, when he lost a playoff match against Lajos Portisch for a place in the Candidates Tournament. He won the prestigious tournament at Wijk aan Zee in 1982, 1990 and 1991.
On the April 2005 FIDE list, Nunn had an Elo rating of 2617, making him number 98 in the world and England's number four (behind Michael Adams, Nigel Short and Luke McShane). His highest ever ranking was equal 9th in the world in January 1985. He has retired from serious tournament play and hasn't played a rated game since August 2006.
As well as being a strong player, Nunn is regarded as one of the best contemporary authors of chess books. He has penned many volumes, including Secrets of Grandmaster Chess which won the British Chess Federation Book of the Year award in 1988 and John Nunn's Best Games which took the award in 1995. He is the director of chess publishers Gambit Publications.
Nunn is also involved with chess problems, composing several examples and solving as part of the British team on several occasions. On this subject he wrote Solving in Style (1985). He won the World Chess Solving Championship in Halkidiki, Greece, in September 2004 and also made his final GM norm in problem solving; he won the World Championship again in 2007.[1] He is the third person ever to gain both over-the-board and solving GM titles (the others being Jonathan Mestel and Ram Soffer).
Since the mid-1990s Nunn has been actively working on data mining from chess endgame tablebases. The products of this work include the books Secrets Of Rook Endings, Secrets of Minor-Piece Endings, and Secrets Of Pawnless Endings. These books include human-usable endgame strategies found by Nunn (and others) by extensive experimentation with tablebases, and new editions have come out and are due as more tablebases are created and tablebases are more deeply data-mined. Nunn is thus (as of 2004) the foremost data miner of chess endgame tablebases. This work corresponds to the endgame part of the work of Berlekamp, Conway et al in dots-and-boxes, Hex and other games.
He is married to Petra Fink-Nunn, a German chess player with the title Woman FIDE Master.
