One semi-final of the 2021 Chess.com Speed Chess Championship has finished, and it was a very close battle that came down to the wire. (I'll give the result in the comments.) The winner of the match, which took place on the 13th, will face the winner of the other semifinal. That takes place on Thursday, December 16 at 5:30 p.m. ET, and sees three-time defending champion Hikaru Nakamura take on Ding Liren.
