Dieter Steinwender, WCCC 1986 [1]

Dieter Steinwender,
a German computer scientist, computer chess expert, writer, journalist, salesperson, chess player (anti computer) and programmer. During his undergraduate at the University of Hamburg, motivated and supported by his advisor Frieder Schwenkel, Dieter Steinwender collaborated with his fellows Alexander Reinefeld, Dirk Hauschildt and Manfred Allers in developing the chess programs Murks for an Interdata M85 (1980) and later (1981-83) MicroMurks for the Motorola 68000 µ-Prozessor [2].

In 1982/83, along with Frieder Schwenkel, Dieter Steinwender played a correspondence chess game versus Belle [3]. In 1984, Dieter Steinwender published a didactic Basic program in Computerschach und Spiele [4], and along with Chrilly Donninger, the Basic program Minimax [5].


Dieter Steinwender is editor in chief of the German computer chess magazine Computerschach und Spiele (CSS). Until 2005 it was a paper magazine with co-publisher and ChessBase co-founder Frederic Friedel. Today the magazine is available online [6] with Steinwender as sole publisher and editor in chief [7] and shareholder of Steinwender EDV-Beratung GbR [8] with the associated CSS-Shop [9] [10] . The close relationships between CSS and CSS-Shop and ChessBase, was criticized as cause of possible conflict of interests related to independent journalism and test-reports of computer chess products [11] .


Dieter Steinwender participated at the Aegon 1996 human-machine championship, and demonstrated some Anti-Computerchess, especially in the game against Shredder [12] .
