Patrol chess is a chess variant in which captures can be made and checks given only if the capturing or checking piece is guarded (or patrolled) by a friendly unit. Non-capturing and non-checking moves are played as normal.
The variant was invented by Frederik Hendrik von Meyenfeldt who published a chess problem using the rules in The Problemist (the magazine of the British Chess Problem Society) in 1975.
Patrol chess has often been used as a condition in chess problems. It is also possible to play complete games under Patrol chess rules.

Famous quotes containing the word chess:
“What have we achieved in mowing down mountain ranges, harnessing the energy of mighty rivers, or moving whole populations about like chess pieces, if we ourselves remain the same restless, miserable, frustrated creatures we were before? To call such activity progress is utter delusion. We may succeed in altering the face of the earth until it is unrecognizable even to the Creator, but if we are unaffected wherein lies the meaning?”
—Henry Miller (1891–1980)
