TCEC S15 and CCC8 Finals Both Underway

A week ago, in Leela Wins TCEC Cup 3; CCC8 S1 99% Finished, we left both of our two world class engine-to-engine competitions with their final stages just getting underway. Here's a recap of that post:-

TCEC: The S15 superfinal started [between Leela and Stockfish] and the score is currently tied at +1-1=11. • CCC: The CCC8 qualifying stage finished in the order -- Stockfish, Leela, Leelenstein, Antifish, Houdini, Komodo -- no tiebreaks required. Leelenstein beat Antifish for the second qualifying spot in the Leela family.

What is the current status of the two tournaments?

TCEC: With just over half of the S15 superfinal games played, Leela leads Stockfish by 27.5-24.5 (+8-5=40). At one point, Leela led by five points.

CCC: Here's a portion of the final crosstable from the CCC8 qualifying stage, showing how the first 12 engines (out of 24 engines total) fared against each other.

In the final stage, with about two-thirds of the games already played, the order of the four engines is Stockfish, Leela, Leelenstein, Houdini. The point spread between each successive place is almost enough to guarantee that this will be the final standing.
