I became aware last week that the World Chess Championship final is taking place in New York, between Carlsen and Karjakin. There have been three games so far, all drawn.
For the first game, defending champion Carlsen chose the Trompovski Attack, an unusual opening at this level. Interviewed afterwards, he said that it was because he is a great admirer of Donald Trump. Meanwhile, Karjakin (who sounds to me like a character from Grand Theft Auto) is a Putin fan*.
The human brain is a curious organ. At once, these two brain-owners can develop theirs to pretty much the highest level possible, whilst remaining remarkably stupid.
*Of course, he would be stupid to say anything different, given that he's Russian. Carlsen, being a Norwegian, has a choice.
