George Orwell [1]

a chess program by Thomas Nitsche developed in the early 70s, when Nitsche was student at University of Freiburg. Orwell III already played the first German computer chess tournament, the First GI Computer Chess Tournament, 1975 in Dortmund [2] , and was runner-up at the First European Computer Chess Championship 1976 in Amsterdam behind Master [3] [4] . Orwell was written in Algol, Simula and Fortran and ran on an Univac 1106/2.


At the WMCCC 1984 in Glasgow, while winning the shared title with Mephisto III A, Elmar Henne and Thomas Nitsche further competed with an experimental program with the Orwell brand-name, running on a 68000 processor of a NDR-Klein-Computer [5] interfaced with a Mephisto Modular board. When Hegener & Glaser abandoned the collaboration with Henne and Nitsche short later, to work with Richard Lang, Henne and Nitsche competed a last time at the WMCCC 1985 with three entries of Orwell, running on 68020 processors.
