Jan Timman (1951) is a former World Championship Candidate who rose to the number two spot of the FIDE world rankings. The Dutch grandmaster was one of the world's leading players from the late 1970s to the early 1990s and is still playing actively in open tournaments and in club leagues.

At the peak of his career he was considered to be the best non-Soviet player and was known as 'The Best of the West'. In 1993 he qualified for the final of the FIDE World Championship, but lost the match against Anatoly Karpov.

He has won the Dutch Chess Championship nine times and has been a Candidate for the World Championship several times. He has won dozens of tournaments, including Wijk aan Zee (1981 and 1985), Linares (1988) and the World Cup tournament in Rotterdam (1989). In a rapid tournament in 1991, in a knock-out format, he beat Gata Kamsky, Anatoly Karpov, Viswanathan Anand and World Champion Garry Kasparov to claim the title.

Timman is one of the best chess writers and annotators. He is the author of several highly acclaimed bestsellers, such as Curaçao 1962, On the Attack!, and Power Chess with Pieces. He is editor of New In Chess magazine and editor-in-chief of New In Chess Yearbook.
