"Stockfish Wins Computer Chess Championship As Neural Networks Play Catch-Up
The reigning Chess.com Computer Chess Champion Stockfish continues to assert itself as the greatest chess engine of all time, recently picking up a win in CCC 9: The Gauntlet.
Stockfish won CCC 9 over Leelenstein, a neural-network chess engine based on Lc0, the leading machine-learning chess project.
The champion engine triumphed in the blitz time control of CCC 9, beating 17 other engines in a "gauntlet" format.
Stockfish now looks to defend its title in CCC 10: Double Digits, an 18-engine tournament played in four rounds. CCC 10 is now in progress—watch at the Computer Chess Championship.

The first three rounds of CCC 10 will all be played at a time control of 10 minutes plus a three-second increment, on the border between blitz and rapid.

The two-engine finals of CCC 10 will be 400 games split up among three blitz and rapid time controls to determine the champion.

The neural network engines, led by Lc0, will try to dethrone the legendary Stockfish. Lc0 and Leelenstein will play in the first two stages, while various less-proven engines will try to qualify. The Allie neural network engine will join the tournament in stage two without playing in stage one.

The latest version of Stockfish, updated on August 5, boasts a big rating gain thanks to a recent patch. CCC organizers estimate the fish will gain a whopping 13 Elo points over its old self.
Lc0 will also bring its A-game to the tournament, running with net 42850, which should be the strongest network produced in the most recent training run, according to CCC planners.

Returning to the Computer Chess Championship is the enigmatic Stoofvlees engine, which is an experimental project combining several cutting-edge artificial intelligence techniques. The Stoofvlees engine uses feature recognizers paired with a neural network that was trained with an oracle of grandmaster games. The results were then built into the Deep Sjeng engine to create the new chess machine. Stoofvlees is written by the former Leela Go author "GCP," and reached the quarterfinals of CCC 9. "
Leelenstein will look for revenge on behalf of the neural-network engines in CCC 10.

Yes Jon....I find these Chess.com games of a very high quality and very interesting....just noticed the fantastic time control
of 10 min +3 sec...so there are no excuses and is enough time for a early strategical approach...has Arasan been entered before in the Chess.com Champs? I don't recall seeing it....Might be a good idea....Andscacs is entered...AR :) :wink:

ps Just happened to view a Wild game today..Queen side castling by black in a modern defense!

I agree. The latest patches for Stockfish are amazing. Stockfish is again best. Lc0 will need to see great things from the T6000 training. And that will take some time. In the mean time. Stockfish will keep improving and widen its lead!

Hey, look!

The *air quotes* World Champion *air quotes* in 5th place! Welcome to the real world!

They have the strongest software around, and they even allow Opening Books instead of repeating silly openings for both sides!

Looks like people are doing something right :)

Congrats to the Stockfish team!
Great spirits have always encountered violent opposition from mediocre minds.

Maybe very interesting, but certainly not very high quality at that time control. Here's a position from the Leelenstein-Stockfish game posted earlier.



Here White played 30. Rd1, losing the game.

This competition is a newer evidence for the statement that NN engines are stronger than Stockfish only in that case if the competitors do not use an independent opening book.
In general there is no serious difference in Elo between Stockfish and the top NN engines.

I have heard that hand-crafted evaluation functions are a way of the past and had introduced bias beyond redemption.
