Some programs score certain terms '''differently''' for the [[Side to move|side]] they are playing and for the opponent. Most often the big terms, like [[King Safety|king safety]], [[Passed Pawn|passed pawn evaluation]] or [[Mobility|mobility]] are scaled in some way. Whilst it might be argued that this idea runs counter the definition of chess as a zero-sum game, it also allows greater freedom in shaping the program's playing style. [[Richard Lang|Richard Lang's]] programs were famous for their asymmetry in evaluation and [[Pruning|forward pruning]] <ref>[http://groups.google.com/group/rec.games.chess.computer/browse_frm/thread/b456400a43207b02 Genius' asymmetric-search by example: TRY yourself] by [[Thorsten Czub]], [[Computer Chess Forums|rgcc]], December 30, 1997</ref> , which emphasis safety (rules like 'do not start a wild attack, but worry a lot if the opponent does so') <ref>[[Kaare Danielsen]] ('''1987''').
