Meltdown

Finally, the world chess championship match between the defending champion, Magnus Carlsen, and his official challenger, Ian Nepomniachtchi, is over. Nepomniachtchi was already trailing by two games when I wrote about the match six days ago. He threw so much caution away in trying to overturn this deficit that his play simply fell apart. Two more losses in the next three games and that was that: the match was over! Carlsen had won 7½-3½.
