Home * Evaluation * Space
Space,
a loosely defined evaluation feature related to square control, in particular center control considered by piece placement dependent on pawn structure. A player controlling more squares than the other is said to have a spatial advantage [2]. Tarrasch's concept of force, space and time [3] and their equivalence (to some extend) is considered by material (force), piece placement and center control (space) and roughly by mobility (space and time).
Contents
Implementations
Some programs have explicit evaluation terms concerning space. For instance, Stockfish defines a space area bonus by the number of safe squares for minor pieces on the central four files on ranks 2 to 4, counting twice if on a rearspan of an own pawn. The space area bonus is multiplied by a weight, determined by the number of own pieces minus number of open files [4]. Toga II 3.0 gives a non-linear bonus for pieces on the opponent half of the board - the more the better [5]. Senpai 2.0 considers space by the "glorified" pawn chain piece-square tables [6].
