Translation from the German WIKI
Hardly a program was eagerly awaited for as the Mephisto REBEL 5.0 because the foundation for this was laid in 1986 Cologne during the computer chess world Championship.
In the course of the tournament REBEL had beaten already impressively several competitors who ran on mainframes. REBEL in the final round got the chance to win the world title since it had a winning position against the American program Be-Be.
Unfortunately the Schröder brainchild couldn't resist to rob another pawn in a profitable position, a fatal mistake and ultimately finished on a 5th place.
