TCEC/CCC 2020-H2 Summary

Six months ago I posted my first semi-annual summary of weekly posts on developments in the world of chess engines: TCEC/CCC 2019-Q4 & 2020-Q1/Q2 Summary (June 2020). Here's the second semi-annual summary.

The first column lists the fortnightly posts covering the two most important, ongoing engine vs. engine tournaments. The second column lists the posts that appeared in the intervening week.
