Opposition

Opposition (from lat. Oppositio - resistance) in chess is a confrontation between kings.  Distinguish the near opposition, when the distance between the kings is one field, and the distant, when the distance between them is 3 or 5 fields.  Oppositions are possible vertically, horizontally and diagonally;  in the latter case, it is called a “scythe”.  Opposition is a special case of correspondence fields.  It is a typical method of struggle for 3 key fields located side by side vertically or horizontally.  Possession of the opposition allows the king to make a round.
