TCEC/CCC 2021-H1 Summary

Six months after the previous summary of posts about the world's two leading engine vs. engine competitions, TCEC/CCC 2020-H2 Summary (December 2020), it's time for another summary. As usual, the first column lists the fortnightly posts on the current status; the second column lists off-week posts on related topics that I wanted to explore in more depth. The last, blank space on the right is a space filler for this current post.

Seeing the titles of all the posts in the left column, shows that the TCEC runs like clockwork. The CCC hasn't run a structured, multi-phase competition in more than three months. What will the next six months bring for the CCC?
