SPCC: Testrun of Reckless 0.9.0 finished

Post by pohl4711 »

My UHO-Top15 Ratinglist is the world's first engine-ratinglist, using UHO-openings, and the world's first ratinglist offering additional Gamepair-statistics.

Testrun of Reckless 0.9.0 finished.

https://www.sp-cc.de

Also take a look at the EAS-Ratinglist, the world's first engine-ratinglist not measuring strength of engines but engines's style of play:
https://www.sp-cc.de/eas-ratinglist.htm

As usual, the most spectacular sac-wins of the latest testrun (won by the tested engine) can be replayed directly on my website. The pgn-viewer (by ChessBase) needs Javascript on and Adblockers off:

Reckless 0.9.0 is still 2 years behind stockfish based on the graphs of SPCC(stockfish16.1 of 2024 is at similiar level to Reckless0.9.0 based on the graphs)

Thank you !
Time flies... SPCC gets 12 years old in may, 2026.
So much work in these years besides doing the ratinglist: Created UHO openings and the EAS Tool, all for a bright future of computerchess.

True, but Stockfish has made very small progress (40 Celo) in these 2 years. Perhaps, Reckless can progress faster? We will see. I am very impressed by the progress of Reckless until now.
But, the higher the Celo, the harder further progress...
Interesting times ahead!

On Full UHO-Ratinglist, Reckless 0.9.0 seems to be significantly stronger than Stockfish 17, and only 11 Elo behind Stockfish 17.1 which was released a little less than a year ago. It seems to me that it's closer to 1 year behind.

As I understand it, the main list is based only on games between the top 15 engines, while the full list also contains older games. So the game pools are different.

Also, I think the main list anchors Stockfish 18 at 3873 Elo, while the full list doesn’t. Although, IMHO, it would be better if it did, so the two lists would be more comparable to each other. But I might be missing something.

Correct. In the full ratinglist, the game (or opponent) pools are different. Very different, when you look at amount of played games.
So, for getting a valid progress-history of Stockfish, the Celo-diagrams on my main site are the better choice!
That is the reason, why I include the #2 engine in there, too. First Torch, now Reckless... Here you have the better view on the race/competition between #1 and #2
