@laatikko Leave them alone. They are simply insecure and scared individuals, who are using a similar strategy to "XY-Problem" only to mislead people.The original question is not, if corona is fake or flu. If they believe it is fake. They should infect themselves with corona to know better and prove to us. By the way one of them was "Mad" Mike Hughes. Their superhero. He is no more. Just saying...
But anyway back to original question.
Question:How much impact will Corona Virus (COVID-19) will have to chess especially OTB chess and OTB tournaments?
Answer: Lots of open tournaments have been canceled.
Question: And also the Candidates tournament are so close. Should they be postponed or not ?
My Answer: Yes, they should. Because it is not a fair tournament by now. Wang Hao is missing his 2nd.
Teimour Radjabov is out, who earned and prepared for the tournament.
MVL was gifted and he is not well prepared.
Question: Will it have any impact to online chess?
My answer: Indirectly, yes. Maybe there will more online tournaments.
