TCEC S16 DivP & CCC10 S3 Both Underway

To summarize last week's post TCEC S16 DivP & CCC10 S2 Both Underway:-

TCEC: The 'Premier Division', to determine which two engines will compete in the Superfinals, is underway with eight engines. • CCC: The 'CCC10 Quarterfinals' are underway with 11 engines.

In the world's strongest engine-vs-engine competitions, what's changed since then?

TCEC: The Premier Division has another week to run. Three engines -- AllieStein, LCZero, and Stockfish -- are currently within a half point of each other, two points ahead of the rest of the field.

CCC: As Chess.com reported in CCC10 Quarterfinals Finished; CCC10 Semis Start Now!, six engines advanced from the quarterfinals. The following chart shows a partial crosstable for those six, with Stockfish, Lc0, and Leelenstein finishing well ahead of the others. None of the other engines managed to win against the top three.

The 'CCC10 Semifinals' stage is currently underway with the same three engines again well ahead of the other three. When I gathered the basic info for this post, the schedule said the event would finish in a couple of days, but later an announcement appeared that said, 'Due to unexpected hardware issues, CCC10 Semifinals will resume [later]'.

Both events have reached the stage that will determine the participants in the finals. If the tournaments progress as the intermediate results show, we will see two AI/NN engines battling against each other -or- Stockfish against one of those engines.

[For further information from the various stakeholders in the engine-to-engine events, see the tab 'TCEC/CCC Links' at the top of this page. • NB: Leela = LC0 = LCzero]
