TCEC S24 DivP, CCC20 Blitz Final : Both Underway

In the previous fortnightly report on the world's two leading engine vs. engine competitions, TCEC S24 L1, CCC20 Blitz Semifinals: Final Week (March 2023), both the TCEC and CCC were well into their respective seasons. Following is a summary of that report.

TCEC: S24 L1 is underway with Koivisto leading by a significant margin. Berserk is in a tie for second place. • CCC: Of the 12 engines that competed in 'CCC20 Blitz Main', six qualified into the 'CCC20 Blitz Semifinals', which is underway.

After another two weeks, both competitions are seeing the usual three engines vying for the top places. Following is the current status.

TCEC: Koivisto won S24 L1 three points ahead of Berserk, which finished a point ahead of the next three engines. Both Koivisto and Berserk promoted into the Premier Division (DivP). With two rounds completed in the eight engine, eight round tournament, they are in fourth and fifth place place, significantly behind KomodoDragon, LCZero, and Stockfish. LCZero beat Stockfish in an early game of the third round.

CCC: In the 'CCC20 Blitz Semifinals', Stockfish, Lc0, and Dragon finished in that order. Lc0 beat Dragon by 32 points in the 500-game 'Challenger Match', and is currently trailing Stockfish by 16 points after a sixth of the 500-game 'Final Match' has been played. This extrapolates to a difference of nearly 100 points when the match will have finished.
