The device prohibition in Art. 11.3.2 is the primary anti-cheating provision in over-the-board play; Organisers may screen players entering the playing venue, subject to FIDE anti-cheating regulations; The scoresheet requirement (Art. 8.1-8.2) creates a verifiable record of every game
Why people argue about this
People often assume that simply having a scoresheet is enough to prevent cheating in chess, forgetting that Art. 11.3.2's device prohibition actually serves as the primary anti-cheating measure. They overlook how organizers can screen players entering the venue and FIDE’s anti-cheating regulations play crucial roles alongside the scoresheet requirement.
