I am slightly disappointed that no-one has replied on the viability of this idea.
A couple of months has elapsed since I proposed it, and face-to-face bridge looks as far away in the distant future as ever. Bridge holiday companies, for example, face the difficult conundrum of whether (and how) to run holidays booked for September/October of this year in continental Europe. Most likely, the Foreign Office will have by then allowed beach holidays to resume, but there will be no way that face-to-face bridge, a standard component in the afternoons and evenings of these bridge holidays, to be safely run.
A pairs bridge-plaing app would remove any need for playing cards, it could observe the two-metre rule, and yet keep everyone in the same ballroom/conference room, thereby minimising the risk of cheating which is so widely suspected oN online venues such as BBO.
