Caruana is playing quickly so far:
After the game, Magnus Carlsen declared that “He seems to have out-prepared me with the black pieces so far so I’ll have to try harder.”
Some controversy sparked just before the game, as a clip showing Fabiano’s daily activities was briefly uploaded to YouTube. The clip contained a few shots of a laptop screen showing openings research. The clip was taken down and it’s unclear if Carlsen’s team extracted any insight from it.
