TCEC S23 DivP, CCC19 Blitz Final : 'Well' Underway

Welcome back to our ongoing coverage of the world's two foremost engine vs. engine competitions. Let's first summarize the previous report from two weeks ago, TCEC S23 Paused; 'CCC19 Blitz Main' Underway (September 2022):-

TCEC: S23 L1 finished with Ethereal and Berserk promoting into DivP. Before that event starts, the site is running 'VSOB22 until replacement GPU'. • CCC: The site is currently running 'CCC19 Blitz Main' with 10 engines. This was preceded by three other 'CCC19 Blitz' events: 'Newcomers', 'Qualifier #1', and 'Qualifier #2'.

The current situation has both sites following a script well known from recent competitions.

TCEC: S23 Premier Division (DivP) is well underway. Stockfish is two points ahead of LCzero and KomodoDragon, which are separated by a half-point. The other five engines have negative scores. The event will finish in a week or so.

CCC: Stockfish won 'CCC19 Blitz Main' ahead of LC0 and Dragon, who were well ahead of the other seven engines. Sound familiar? If not, see the previous paragraph. Ethereal led the also-rans and managed a positive score.

Repeat that previous paragraph for the 'CCC19 Blitz Semifinals', substituting 'other three engines' and 'negative score'. In the 'CCC19 Blitz Challenger Match', Dragon beat LC0 by six points in a 300 game match. Stockfish is pummelling Dragon in the 'CCC19 Blitz Final' match.

That pattern has been repeating for many months. Suggested template for future posts (respectfully respecting the respective 'NB' in the footnote):-

Round-robin: 'Stockfish won _____ [well] ahead of LC0 and Dragon [or vice versa] which finished ahead of [number] other engines.' • Match: 'Stockfish beat [(Choose one:) LC0 -or- Dragon] in the _____.'

Will some extraordinary event break the routine? Perhaps a respectful retrospective look would be revealing.
