In Contempt of Hate [1]
The Contempt Factor reflects the estimated superiority/inferiority of the program over its opponent. The Contempt factor is assigned as draw score to avoid (early) draws against apparently weaker opponents, or to prefer draws versus stronger opponents otherwise.
Contents
Too little Respect
For stronger programs it might be dangerous to avoid draws by Fifty-move Rule, as happened for instance at the 1st World Computer Rapid Chess Championship in the game between HIARCS and Alaric aka TerraPi [2] .
Too much Respect
An example of too much respect appeared during the WMCCC 1990 in Lyon, Mephisto versus Échec [3] . Échec had something like +4 pawn-units for the final repeated position, while it had almost a won game otherwise.
