TCEC FRC3, CCC Rapid 2021 : Both Finals Underway

The previous post on the world's premier engine vs. engine tournaments, TCEC Cup 8, CCC Rapid 2021 : Semifinals Both Underway (March 2021), was all about semifinals. Here is a summary:-

TCEC: In TCEC Cup 8, the 32 starting engines have been winnowed to four engines in the semifinal. The final match will finish this week. The next event is scheduled to be FRC3, 'Fischer Random Chess 3 with the 16(+) Season 20 FRC engines'. • CCC: The Rapid 2021 'Elite Round' of six engines should finish in a few days. The top two will qualify into the 500 game final match.

This post is all about semifinals. Here is the current situation:-

TCEC: In the TCEC Cup 8 semifinal, Stockfish beat KomodoDragon +1-0=5 and LCZero beat AllieStein +1-0=11. In the final match, Stockfish beat LCZero +1-0=7. In all three matches, a single decisive game determined the winner.

FRC3 has reached the final match, where Stockfish and KomodoDragon are tied with one win each after 29 of the 50 games have been played. The following chart from the TCEC Wiki shows the different stages of the event.

After the final match finishes, I'll have more to say about the tournament on my chess960 blog. I covered the previous edition in TCEC FRC2 (December 2020). In that event, Stockfish beat LCZero +8-0=42.

CCC: Stockfish is crushing Lc0 in the final match, which should finish this week. In the minimatch between the two engines for the qualifying 'Elite Round', Stockfish won +14-5=21. Looking ahead, what are the CCC's plans? Both the CCC club and the Discord channel are ghost towns.
