✅ About Jan Timman
🔵 Jan Timman
🔹 Dutch chess Grandmaster
🔰 Jan Timman is a Dutch chess Grandmaster who was one of the world's leading players from the late 1970s to the early 1990s. 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".
He has won the Dutch Chess Championship nine times and has been a Candidate for the World Championship several times. He lost the title match of the 1993 FIDE World Championship against Anatoly Karpov.

He received the International Master title in 1971, and in 1974 attained Grandmaster status, making him the Netherlands' third after Max Euwe and Jan Hein Donner. In the same year he won the Dutch Championship for the first time.
