Despite the fact that I purchased tickets for this year's event long ago, I can't see any value to having the Mosconi at all this year. There has been almost no tournament play this year and, at present, there is neither a Team USA nor a Team Europe nor a reasonable basis for selection of teams.
Having the event with no fans would be ridiculous. What makes the Mosconi Cup different from all the other events is the raucous atmosphere provided by the thousands of fans in attendance at the Alexandra Palace, this year's scheduled venue. To my knowledge, it's the only event of the pool year in which a single table event is watched live by thousands at a time.
I guess Matchroom may feel they can salvage something by staging the event, possibly with last year's teams consisting of players out of form, making it a stream only event with no fans present. They might also overhaul it for 2020 and replace it with some kind of exhibition match/matches of their own choosing, but then it would no longer be the Mosconi Cup. To me, though, cancellation seems the best course of action, as postponement would be a risky path that might well result in cancellation later on.
Matchroom, our sport's shining example and top event producer deserves better than what they got in 2020. Like most businesses, they have suffered during the pandemic. Like other businesses, they're surely looking for ways to stop the bleeding and reestablish their presence in their marketplace.
From my vantage point, Matchroom has little choice but cancellation, but we've seen them work miracles at Matchroom before, so perhaps there's room for a little optimism here.
Finally, as if it need be said, international travel between America and Europe remains a risky proposition, and asking it of anybody is possibly unfair.
