Patrol chess is a variant of chess in which a capture may be made, and a check given, only by a piece that is guarded, or patrolled, by a friendly unit. Moves that neither capture nor give check are played exactly as in the orthodox game. The variant was devised by Frederik Hendrik von Meyenfeldt, who published a chess problem built on its rules in The Problemist, the magazine of the British Chess Problem Society, in 1975. Since then it has often been used as a condition in chess problems, where the composer requires the solution to obey the patrol rule, although complete games can also be played under it. Its effect is that an unsupported king cannot take an unsupported piece, and a piece with no friendly cover does not deliver check, so attacks and mating nets depend on pieces covering one another. The Wikipedia article illustrates this with a position in which a white king cannot capture a knight and a rook gives no check until a second knight arrives to patrol it.
