Two quarterfinal matches of the 2021 Chess.com Speed Chess Championship were contested today, and neither was close. The first was between Ding Liren and Levon Aronian, and the second between Hikaru Nakamura and Anish Giri. (The results, and a brief comment or two about each match, will be given in the comments.) The winners will face off in one semi-final, and Nihal Sarin will play the winner of the last quarterfinal match, between Wesley So and Fabiano Caruana. That last match will be played on the next (and possibly final) rest day of the world championship match, which is this coming Thursday.
