More TCEC Bonuses; CCC11 Semifinal Underway

Time to get up-to-date on the world's premier, ongoing engine vs. competitions. To summarize the previous post, TCEC/CCC Bonus Events, from two weeks ago:-

TCEC: The site is running a series of bonus tournaments; the current event is titled 'Viewer Submitted Openings Bonus 4', with eight engines. • CCC: CCC11 R2 finished with Lc0 3.0 points ahead of second place Stockfish. After R2, the CCC ran two matches; Fat Fritz lost to both Stockfish and Lc0 by convincing margins.

TCEC is still in a holding pattern, while CCC has advanced another stage. Let's have some specifics.

TCEC: The site has progressed to 'Viewer Submitted Openings Bonus 9'. As for the next season (S17), the schedule is nearly identical to what was announced two weeks ago; it says:-

!s17 • Tentatively set mid-December 2019. Delay due to a potential sponsored hardware upgrade.

The plans for the various stages of S17 are still unannounced.

CCC: CCC11 R3 finished with AI/NN engines Leelenstein and Lc0 tied for 1st/2nd, a half-point ahead of Stockfish. Komodo placed fourth, 6.5 points behind Stockfish. The following chart shows the full R3 crosstable. There was only one decisive game among the top three engines, and the two AI/NN engines lost no games.

The top four engines qualified into the CCC11 Semifinal round, which is just getting underway. The tournament is projected to run for somewhat less than a week. The top two engines in the semifinal will advance to a 75-game final.
