TCEC: Stockfish won 'Swiss 3' a half point ahead of LCZero, which was two points ahead of Berserk. KomodoDragon finished in fourth place, a half point behind Berserk and a half point ahead of the next five engines. After a 'Stockfish Simul', the site ran FRC5, which reached the four engine 'Final League' stage (with KomodoDragon missing). • CCC: In the 'CCC17 Blitz' semifinal stage, Stockfish finished well ahead of Dragon and Lc0. The other three engines had substantial minus scores. In the challenger match, Lc0 beat Dragon, earning the right to challenge Stockfish. In the final match, Stockfish beat Lc0, to win the 'CCC17 Blitz' tournament. The site then conducted the 'CCC18 Rapid' Qualification stage, starting the CCC's cycle of Rapid, Bullet, and Blitz tournaments again.
This current post covers the single fortnight that has passed since then.
TCEC: This past weekend I covered the FRC5 event on my chess960 blog in a post cryptically titled TCEC C960 FRC5 (July 2022). Stockfish beat LCZero in the final match.
The site is currently conducting 'DFRC 1'. I couldn't find the event on the TCEC wiki. The !dfrc command informs,
Double Fischer random chess: The same as Fischer random chess, except the White and Black starting positions do not necessarily mirror each other. Double FRC has 921,600 (960*960) possible starting positions.
The !dfrc1 command informs,
26 participants (FRC5 + Bagatur), Swiss format, games from starting positions, 11 rounds, and 30min+3s TC. Estimated duration: 12 days.
LCZero is currently ahead of Stockfish and KomodoDragon, although the three engines have not (yet) played the same number of games. Like FRC5, I'll cover the event on my chess960 blog, where I post twice a month.
CCC: From the 'CCC18 Rapid' Qualification stage, Rofchade, Seer, and Revenge promoted into the Main stage, where they joined nine other engines. Rofchade missed promoting into the Semifinal stage by a half point. Leading that stage -- you guessed it -- are Stockfish, Dragon, and LC0, already by a comfortable margin over the other three engines, although the stage is only at the end of the first round robin.

What do you think of this?
ReplyDelete> Is the standard starting position optimal? (Blind Fischer double-“random”)

> This got me thinking whether the starting position might actually be one of the “best possible” Chess960 setups. To give this claim meaning, consider the following made-up chess variant:
> Both players secretly write down a starting (valid Chess960) first rank for themselves. They then reveal their ranks and set up their positions accordingly, followed by playing Fischer random chess in the usual way, except with different setups for the two colors.
