Ian Wallis has correctly pointed out that the SCCA rules differ from the FIDE laws. Revised at last year's AGM, the relevant SCCA rule (1.4) now states: "Should any mobile electronic equipment emit a sound during play, the player in possession of it must immediately offer to resign. His opponent may decline this offer."
So the SCCA is taking a more benign view than FIDE. Has anyone experienced this new rule in action during this season? (Apart from the one cited in the recent article).
