TCEC/CCC 2019-Q4 & 2020-Q1/Q2 Summary

Last year, in TCEC/CCC 2019 Q1-Q3 Summary (October 2019), I decided,

After following the TCEC & the CCC for nine months, and with both events transitioning to new seasons, this looks like a good time to end the blog's coverage. [...] I'm going to have trouble keeping my distance from the action, so I wouldn't be surprised to come back to these events.

I didn't manage to stay away and was back with a new post a week later. The only change was to post every two weeks, tackling a related subject on the off-week. Here's a summary of the posts since then.

Since a summary after nine months doesn't fit well into an annual pattern, I'll produce the next summary after six months.
