TCEC S23, CCC19 Rapid : Stockfish Wins Both

The previous report on the globe's top engine vs. engine ongoing tournaments was TCEC S23 Sufi, CCC19 Rapid : Nearing the Finish (November 2022). Here's a summary of that report.

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: In the 'CCC19 Rapid Semifinal', Stockfish, Lc0, and Dragon (1-2-3 in that order) -- are in the lead for the 'Challenger' (2-3) and 'Final' (1-?) matches.

Stockfish won both events by significant margins. The rest of this post gives a few details.

TCEC: Stockfish beat LCZero +27-10=63 to win its sixth straight Superfinal (Sufi). The site is currently conducting a 100 game 'Subfinal', where LCzero has already clinched victory over KomodoDragon. Plans for season 24 (S24) are already available on the site's Wiki.

(Blue links are available pages; red links are TBD.)

CCC: In the 'CCC19 Rapid Semifinal', Stockfish, Lc0, and Dragon finished 1-2-3, with the other three engines as distant also-rans. LC0 beat Dragon by three points in the 200-game 'Challenger' match and is currently trailing Stockfish in the 200-game 'Final' match. The really dumb money is on LC0. The only unknown is the margin of victory.

What's next for the site? My guess is 'CCC19 Bullet', but the !next command says 'Bonus Events!'. We'll find out soon enough.
