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. [|Tarrasch's] concept of force, space and time and their equivalence (to some extend) is considered by material (force), piece placement and center control (space) and roughly by mobility (space and time). || toc =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. Toga II 3.0 gives a non-linear bonus for pieces on the opponent half of the board - the more the better. Senpai 2.0 considers space by the "glorified" pawn chain piece-square tables.
