is it the right place to migrate from r/chess?

I would say yes, of course the community m/chess is also pretty new, but the community is becoming more and more active. Welcome!

That's what I came here to check, mate.

Well take a look around lol. Both communities seem to be just starting up, so the content might be lacking. It seems like there’s been more activity here vs lemmy.world

@Mathusalem It is according to sub.rehab*, a site that lists alternative homes for subreddits. But this magazine is 2 weeks old, so it's early days.

*Not sure if everything it lists is genuine/accurate, but it does let you filter for "official" alternatives.

It's still to early to decide what's the successor, post-reddit communities are still forming
