I think it would be good, were it not for that it would gut a lot of groups, including the national teams (and thus the World League, etc). It would make it nearly impossible for smaller countries to compete even in their own divisions.
There is already the option to accept games only from premium members, make premium-member only tournaments and groups, and such.
For me, and hoping to not sound like a shill for Chess.com here, I would say there are already very many benefits for premium membership, especially the diamond level. Of course, it depends on what you are likely to use. I use almost everything that the site offers.
Hello,
I'd like to suggest that chess.com opens a companion website (chess-vip.com ?), with the same features than the current one, but with access exclusively to premium members.
I think this would increase the quality of the premium membership by offering better forums, better overall atmosphere and less cheating (having to pay to cheat is a good filter).
This move would make me reconsider premium membership. What do premium members think ?
