to chess. Click on the picture for a company profile.
In 1985, our first commercial chess program named REBEL 5.0,
was released in a stand-alone chess computer by Mephisto Hegener & Glaser, Munich, Germany.
Many stand-alone chess computers followed, including the well-known Mephisto
MM5, Mephisto Polgar, Mephisto Milano,
and Mephisto Risc.
In 1991, our microcomputer program the Chess Machine was declared World
Champion in the Micro tournament in Vancouver. But that was only the
beginning! The next year, in Madrid, an improved version of Chess Machine
won the World Champion title for ALL CLASSES. It was the first time a
microcomputer chess program defeated programs on huge mainframe computers.
The mainframes' domination of computer chess was finally broken!
In 1993, in cooperation with
Hegener & Glaser, we released our first PC-based chess program,
In 1994 we returned to our own brandname, REBEL.
But the absolute peak for Rebel Company came in 1998. On the island Ischia in Italy REBEL 10.0
during a 3-day event defeated second world player Vishy Anand (elo 2795) in a 8
game match with 5-3 using a new algorithm called anti-GM.
