TCEC Cup 11 Underway; CCC19 Bullet in Semifinals

In this blog's ongoing series covering the world's top-two ongoing engine vs. engine tournaments, the last post of 2022 was TCEC More Interludes; CCC19 Bullet Underway (December 2022). Following is a summary of that post.

TCEC: Stockfish won the VVLTC, then drew the two-game SVVLTC with LCZero. KomodoDragon placed first in the top-3 section of 'Noomen Extra 2'; Ethereal placed first in the next-11 section. LCZero then won the second chess324 tournament, a half point ahead of Stockfish. The site is currently conducting '4k Testing'. • CCC: After the 'CCC19 Rapid Final', there were so many CCC exhibition events that it's useful to list them; of 18 recent events, 10 were exhibitions. The site is currently running the 'CCC19 Bullet' event and has updated the event's 'Info' tab to explain its different stages. The 'CCC19 Bullet Newcomers' and 'Qualifier #1' events have finished, and 'Qualifier #2' is underway.

What's the situation two weeks later at the start of 2023? Glad you asked...

TCEC: Engine ice4 won the S23 4k tournament ahead of 4ku and three other engines; see the 'TCEC More Interludes' post for an explanation of '4k'. The site then launched into 'Cup 11', which is currently in the Round-of-16 stage; see TCEC Cup 11 (wiki.chessdom.org), for more info on the event. See also Stockfish Wins TCEC Cup 10; TCEC Swiss 3, CCC17 Blitz both Underway (June 2022; on this blog) for the previous event.

CCC: Four engines promoted from 'CCC19 Bullet Qualifier #2', and joined eight other seeded engines in the 'Main' event. The top six engines then qualified into the 'Semifinals', where more than a third of the games have been played. Stockfish has a significant lead over Dragon and Lc0, which have an even bigger lead over the other three engines.
