TCEC S23 Sufi, CCC19 Rapid : Nearing the Finish

Continuing with this blog's fortnightly coverage of the world's two foremost, ongoing engine vs. engine competitions, the previous post was TCEC S23 Sufi, CCC19 Rapid : Both Underway (October 2022). To summarize that post:-

TCEC: In S23 DivP Stockfish won all of its mini-matches, finishing three points ahead of LCzero and KomodoDragon; LCZero had tiebreak superior to KomodoDragon. The 100-game Sufi has seen five games finish, with Stockfish having a one point lead over LCZero. • CCC: In the 'CCC19 Blitz Final' 300-game match, Stockfish beat Dragon by 60 points. Eight engines competed in each of the 'CCC19 Rapid' Newcomers, Qualifier #1, and Qualifier #2 stages. The next stage should be the 'Main' event.

Both the S23 Sufi and the CCC19 Rapid are nearing the finish. Both events should know the overall winner by our next fortnightly report. The smart money is on Stockfish to win both.

TCEC: After 83 games in the S23 Sufi ('Superfinal'), Stockfish leads LCZero +19-6=58. It needs only 2.5 more points to clinch its sixth straight Sufi.

CCC: Of the four engines promoting from 'CCC19 Rapid Qualifier #2' to the 'Main' stage, a three-way tie for fourth place was decided by a tiebreak match. Revenge thereby joined Minic as a second engine promoting from 'Qualifier #1' through 'Qualifier #2' to 'Main', in which ten engines competed for six places promoting to the 'Semifinal' stage.

Revenge promoted into the 'Semifinal', where it is currently in last place. The usual suspects -- Stockfish, Lc0, and Dragon (1-2-3 in that order) -- are in the lead for the 'Challenger' (2-3) and 'Final' (1-?) matches.
