TCEC S20 Reaches DivP; CCC Testing

The previous post on the world's two most visible engine vs. engine competitions, TCEC S20 Reaches L1; CCC Regrouping (December 2020), might have been the shortest report in the two years since I started following the events regularly; that first post was TCEC S14 Underway (January 2019). To summarize the post from two weeks ago:-

TCEC: S20 'League 3' (L3) finished with a pair of NNUE engines qualifying into L2. One of them, Nemorino, also qualified into L1, which is currently underway. • CCC: The site announced, 'Bonus with updated Leela and SF. Then testing and showcase of engines new to CCC. CCC main event with over twenty engines coming later with a new hardware rig.'

This current post is even shorter. How will I summarize it for the next post in two weeks?

TCEC: S20 L1 finished with Ethereal and rofChade qualifying into Premier Division (aka DivP), which is currently underway. The top two engines will qualify into the S20 final match (aka Superfinal, aka Sufi). With a week and a half remaining, DivP is nearing the half way point. Stockfish has a comfortable lead over LCZero which has a similar lead over third placed KomodoDragon (once known simply as 'Dragon').

CCC: Who knows what evol lurks in the heart(s) of the CCC admin(s)? The 'testing and showcase of engines new to CCC' mentioned in the previous report has evolved into 'testing and showcase of new engines at CCC and of the new hardware rig'. The current event is called 'CCC Testing system changes V'.
