Someone who's really fond of Chess professional scene is the ideal one to make that general thread for everyone to keep the discussion going. Whether it's the World Championship, there will be a continuous discussion about it. I've started to play Chess again online and that's why that general thread would be helpful for me to dive in to see those grandmasters and professionals that have been in the competition. I have a source to look out time after time but I think it's still good to have a conversation from those who know more.
Not only for Chess for every sports there must a general thread where every event about that sports is discussed. For instance, there is general thread about cricket T20 format. Now everything related to T20 whether its World Cup or some other tournament it's discussed there.
This Chess match between Carlsen and Nepomniachtchi was played back 2 months ago. Still we have an active thread about that match.
