After six rounds, three players shared the lead. Two play each other in round seven. Magnus Carlsen, Fabiano Caruana, and Ding Liren shared first place with 4/6. In round seven, Caruana -- Ding was an important game.
Caruana won the game!
I was not able to follow this game live due to responsibilities as the tournament director for a youth chess tournament. Hence, I did not even know the result until the end of a long day.
I will annotate this game during the off day, Monday 25 January and then update this post.
