Stockfish Wins TCEC S16; CCC11 Underway

In last week's post TCEC S16 Final Widens; CCC10 Bonuses on the two foremost engine-vs-engine tournaments, I decided,

After following the TCEC & the CCC for nine months, and with both events transitioning to new seasons, this looks like a good time to end the blog's coverage. I'll produce a summary of those nine months for my next post.

I jumped the gun with that decision. Here's a summary of the rest of that post:-

TCEC: Stockfish now has an eight point lead over AllieStein. This extrapolates to a 56-44 match win for Stockfish. • CCC: No plans for CCC11 have been announced.

Two significant evolutions took place during the week. Both signal a logical break in my ongoing series on engine tournaments.

TCEC: Stockfish beat AllieStein by a final score of 54.5-45.5, more specifically +14-5=81.

CCC: Chess.com announced, CCC11 Starts Now!: 'Title says it all. So head over to chess.com/ccc and join the fun.'

The announcement continued, 'CCC11 format is available here', with a link to a document on docs.google.com/spreadsheets. When I tried to access the document, I received the message 'Access Denied: You need permission', so I'm out of luck. The 'CCC11 Qualification' is already underway with 12 engines competing.

What about that summary of the past nine months? I'll have that in my next post. In the meantime, here's a reminder of other winners during the past few months:-

• 2019-09-30: TCEC S16 Final Underway; Leelenstein Wins CCC10
• 2019-07-15: TCEC S16 Starts; CCC9 Finishes • CCC9 Final: Stockfish over Leelenstein
• 2019-05-27: Leela Wins TCEC S15; Stockfish Wins CCC8 Finals

In a nutshell, recent winners were -- TCEC S15: Leela; S16: Stockfish • CCC8: Stockfish; CCC9: Stockfish; CCC10: Leelenstein. Neither the traditional A/B engines (represented by Stockfish), nor the more recent AI/NN engines (Leela & Leelenstein) can claim dominance.
