incredibly superficial, partly because of the lack of fitness.) This is not so
much a matter of a bit of extra padding, which many of us are guilty of, but

win on demand to ensure a second place finish along with a not entirely
irrelevant reserve spot for the World Championship, should Magnus Carlsen
decide that classical time-control chess is no longer interesting. His
strategy for the game was entirely reasonable. He played a dull technical game
without dynamics, allowing Nakamura to make his own mistakes without any
special involvement from Ding. This is how Nakamura should have played against
Radjabov, and how Caruana should have played against Duda. It often works more

of bullet against Daniel Naroditsky last night. It did not help his

flack for saying that the level of this Candidates tournament has been low. I
