Over the Board chess has resumed.  In one of the countries the government has a Track and Trace system in operation.  This means that mobile phones run an app which records other phones in the area.  If the owner of one of these phones gets the disease then all of those he has been in contact with are notified and asked to self isolate.

         Some players ask that they are allowed to have their phones with them and on during play. 

         What would you say? (3)
