Space bonus in presence of open files If the opponent has a cramped position, opening a file often helps him/her to exchange pieces, so it makes sense to reduce the space bonus if there are open files. Credits: Leonardo Ljubičić for the strategic idea, Alain Savard for the implementation of the open files calculation, "CrunchyNYC" for the compensation of the numerator.
