There was a nice symmetry: two of the day's mini-matches were done in three games, with the winner winning the first two and drawing the third; meanwhile, the other two matches saw one player win the first game, his opponent win the second, followed by two draws to split the match. The day's winners were Magnus Carlsen and Wesley So, defeating Levon Aronian and Alireza Firouzja, respectively; the draws were in the Ian Nepomniachtchi vs. Hikaru Nakamura and Maxime Vachier-Lagrave vs. Anish Giri matches, with the first-named player winning the first game before losing the second.
Remember, advancement to the semi-finals means triumphing over the course of two days, so Aronian and Firouzja are still alive and kicking.
