Henry Moore - Helmed Head N° 2 [1]

Some programs score certain terms differently for the side they are playing and for the opponent. Most often the big terms, like king safety, passed pawn evaluation or 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's programs were famous for their asymmetry in evaluation and forward pruning [2] , which emphasis safety (rules like 'do not start a wild attack, but worry a lot if the opponent does so') [3] .
