He learned the game at the age of 5 from his father, Hans Knaak.
Further development led to him being awarded the International Master title in 1973 and the Grandmaster title in 1975. Meanwhile, in pursuit of a career, he took up a degree course in Mathematics in 1971 and followed this with a teaching diploma. Prior to unification in 1990, Knaak represented East Germany (otherwise known as the German Democratic Republic) and enjoyed unbridled success in the national championship, taking the title in 1974, 1978, 1982, 1983 and 1984, while finishing a close runner-up in 1975.
In team events, he played on the German Democratic Republic"s Chess Olympiad team at Skopje 1972, Thessaloniki 1988 and Novi Sad 1990.
He has also played league chess in the Chess Bundesliga, for Porz and Werder Bremen. There were some notable outright second places too, at Halle 1974 (after Tal), Bucharest 1975 and Trnava 1980 (after Sturua).
At Zinnowitz 1971, Sandomierz 1976 and Potsdam 1985, he shared second place, at Bucharest 1973 came third, and at Camagüey 1974, finished fourth. Knaak has written a number of books and articles about chess, mostly for ChessBase"s publishing wing, where he has been a full-time employee since 1994.
Unlike most grandmaster offerings, his writing is not always confined to the mechanics of the game, but frequently delves into chess history, particularly relating to the famous tournaments and great champions of the past
His treatise on Paul Morphy, co-written with Karsten Müller, received a complimentary review from esteemed critic John Watson, who considered the work would turn out to be more factually accurate than much that had previously been written. In his life outside of chess, he has been married since 1977 and has two children.
Rapid progress brought him to the pinnacle of junior chess and in 1966, 1969 and 1970, he was crowned national junior champion in his age range. Throughout the seventies and eighties he rivalled Wolfgang Uhlmann as the nation"s best player. At the latter event, he delivered an impressive 68% score, including a win against the strong French General Motors Joël Lautier. In international tournaments he has achieved first places at Olomouc 1972, Leipzig 1977 (shared with Malich and Smejkal), Halle 1978 (shared with Farago and Uhlmann) and Cienfuegos 1984.
